Obsidian One | RX 9060 XT 16GB + Ryzen 5 7500F | Ready-to-Go Gaming PC | PC36

💎 Obsidian One

Two panes of glass and nothing to hide behind them

Most cases are a single box, and everything you would rather not look at has to be hidden somewhere inside it. The Corsair 2500X is two boxes. The left chamber, behind tempered glass across the front and down one side, holds the motherboard, the processor, the cooler and the graphics card. The right chamber, behind mesh, holds the power supply, the drives and the whole cable loom.

That split is why we build in this case, and it's why Obsidian One takes longer to put together than a machine in a plain box. Glass on two sides means there is no bad angle and nowhere for a lazy cable run to hide. The 2500X also ships with no fans at all, so every fan you can see through that glass is one we chose and fitted.

Behind the glass it's a straightforward 1440p machine: a Ryzen 5 7500F and a Radeon RX 9060 XT with 16GB of memory, on a board with a full PCIe 5.0 slot and room for two more drives. High settings at 1440p today, and a case and a power supply with room for a good deal more than that when you want it.

🧬 Built to last, designed to evolve

This system is built on AMD's latest AM5 platform, which offers one of the best upgrade paths available today. That means you can start with a great processor now and still have room to move up the stack later, while keeping the same motherboard, case, power supply and most of your core components. The case takes graphics cards up to 400mm and the power supply is deliberately larger than this build needs, so the obvious upgrade in a couple of years is a straight swap rather than a rebuild.

📃 Specifications

• 🧠 CPU: AMD Ryzen 5 7500F
  Click or tap for deeper spec info

  • 6 cores, 12 threads of Zen 4, boosting to 5.0GHz, with 32MB of L3 cache
  • The 7500F is the 7600 without the integrated graphics, and because you are fitting a graphics card anyway, that omission costs you nothing and saves real money. It is the most sensible processor in the AM5 range at this price
  • 65W TDP, though in practice it boosts past that and will pull around 88W with every core loaded. That is still a modest heat load, and the tower cooler fitted absorbs it without ever becoming something you can hear
  • At 1440p with this class of graphics card, the card is what sets your frame rate, not the processor. Spending more here would not show up on screen
  • AM5 is a live socket. When you do want more processor, a 7800X3D or a 9800X3D drops straight in without touching anything else
• ❄️ CPU cooler: Thermalright Assassin X 120 Refined SE ARGB
  Click or tap for deeper spec info

  • A tower cooler running 4 × 6mm direct-touch nickel-plated copper heatpipes through 51 aluminium fins, with a 120mm ARGB PWM fan
  • Rated to 225W, which is well over twice what this processor draws with every core loaded. It isn't merely adequate here, it's comfortable, and that is why the fan stays slow enough to disappear into the room
  • We fit the ARGB version on this build rather than the plain black one. It costs us the same and this is a case with glass on two sides, so the lighting is part of what you are paying for
  • 148mm tall, and it does not overhang the DIMM slots, so all four memory slots stay reachable if you add a second stick later
  • Mounted with Arctic MX-4 paste, applied by hand
  • The 2500X takes coolers up to 180mm tall, which is unusually generous for a micro-ATX case, so there is a great deal of room here if you upgrade the processor later
  • Thermalright back it with a 3 year warranty
• 🔲 Motherboard: ASRock B850M Pro-A WiFi (micro-ATX)
  Click or tap for deeper spec info

  • 8+2+1 phase Dr.MOS power design. Plain English translation: comfortably more power delivery than a 65W processor will ever ask for, and enough for a 9800X3D if you upgrade later
  • PCIe 5.0 x16 for the graphics card, steel reinforced. Worth saying clearly, because Gen5 graphics slots are optional on the B850 chipset and plenty of boards at this price only give you Gen4. This one is the real thing, and the metal bracing matters when a heavy card is hanging off it
  • Three M.2 slots, the first PCIe Gen5 x4 and the other two Gen4 x4, so two stay free for drives you add later
  • Four DDR5 slots supporting up to 256GB, with three free on this build
  • Wi-Fi 6E, Bluetooth 5.2 and 2.5 Gigabit Ethernet. The 6E part means the 6GHz band, and 2.5G wired is a genuine step up from the gigabit ports found on most boards at this price
  • A BIOS Flashback button on the rear panel, which lets the board be updated with no processor fitted. That is a builder's feature rather than a buyer's, but it is part of why we choose this board
  • Realtek ALC897 audio. This is the standard codec at this tier and it is fine for headphones and desk speakers. If you use a dedicated DAC or an audio interface it is irrelevant, and if you do not, you will not notice
  • PC36 only uses motherboards chosen for stability and longevity. See our Trusted brands page
• 📏 Memory / RAM: 16GB (1×16GB) DDR5-6000 CL36
  Click or tap for deeper spec info

  • EXPO-tuned DDR5-6000 CL36, the speed and timing combination Ryzen responds to best on AM5. We fit CL36 rather than the slower CL40 kits often used at this price
  • One stick rather than two, and we will explain the reasoning properly rather than gloss over it. DDR5 pricing is unusually high at the moment. A second stick adds a meaningful amount to a machine at this price, and fitting one is how we keep the 16GB graphics card in the build without the total climbing
  • The honest numbers. A single DDR5 stick is not penalised the way a single DDR4 stick was, because each DDR5 module runs two independent sub-channels internally rather than one. The gap against a matched pair is real but small: roughly 4 to 9 percent in genuinely processor-intensive games, and close to nothing everywhere else. In the games this build is bought for, the graphics card is the limit long before the memory is
  • If you would rather have dual channel from day one, ask us on live chat and we will fit 2×8GB for a small supplement. We would not usually recommend it: a pair of 8GB sticks costs more than the single 16GB and leaves you at the same 16GB. The better route is a second matching 16GB stick, and with four slots on this board there is room to do that whenever you like
  • 16GB is enough for every current game at 1440p. If you stream, keep a lot open alongside a game, or do creative work, take the 32GB option below and skip the two-step
  • Specification guaranteed, model may vary. Happy to confirm the exact part on request
• 💾 Storage: 1TB NVMe PCIe 4.0 SSD
  Click or tap for deeper spec info

  • Rated at 5,000MB/s or better. Games load in seconds and Windows feels instant
  • This is a QLC drive, which is the honest tier for this price. It is quick for everything you will do day to day, and it slows down only during very long sustained writes such as moving hundreds of gigabytes in one go. For gaming and normal use you would not notice the difference
  • Two further M.2 slots sit free, one of them Gen5, plus room in the rear chamber for two 2.5 inch and two 3.5 inch drives. Adding storage later is easy and cheap
  • We fit 1TB as standard across the whole range rather than varying it by price, so comparing our machines to each other is straightforward. The 2TB option is below if you want it
  • Specification guaranteed, model may vary. Happy to confirm the exact part on request
• 🎮 Graphics card: AMD Radeon RX 9060 XT 16GB
  Click or tap for deeper spec info

  • RDNA 4 with 16GB of GDDR6. The memory is the headline here: 16GB at this price is unusual, and it is what stops the card running out of room in texture-heavy games at 1440p while cards with 8GB start stuttering
  • Comfortable 1440p at high settings in modern titles, and very high frame rates in competitive games at 1080p or 1440p
  • Supports FSR 4, AMD's machine-learning upscaler, which is a real step up from FSR 3 and is limited to RDNA 4 cards like this one. It is the reason a card at this price still has life in it in two years
  • AV1 encoding for streaming and recording at a much better quality-to-bitrate ratio than older codecs
  • Being straight about ray tracing: Radeon cards are still behind NVIDIA here, and this one is no exception. Ray traced games are playable at 1440p with upscaling on, but if heavy ray tracing is your priority rather than raw frame rate, say so on live chat and we will point you at an NVIDIA build instead
  • The chipset and VRAM are guaranteed: it will always be an RX 9060 XT with 16GB. The AIB brand varies with availability, and we only use established manufacturers. See our Trusted brands page for more info
• 🧰 Case: Corsair 2500X, Black
  Click or tap for deeper spec info

  • 376 × 469 × 304mm, roughly 54 litres. Micro-ATX, with four expansion slots
  • Dual chamber. The left side, behind the glass, holds the motherboard, processor, cooler and graphics card. The right side, behind a mesh panel, holds the power supply, the drives and every cable. The two are separated by the motherboard tray
  • Tempered glass on the front and the left side, lightly smoke tinted. Mesh on the right, with a dust filter over the power supply intake
  • Around 100mm of space behind the motherboard tray, which is genuinely exceptional for a case this size and is the whole reason the cable side works
  • Graphics cards up to 400mm, CPU coolers up to 180mm, power supplies up to 225mm. Nothing in this build comes close to any of those, which is why it upgrades so easily
  • Front I/O is USB-C, two USB-A and a combined headphone and microphone jack
  • Two 3.5 inch and two 2.5 inch drive mounts in the rear chamber
  • It also supports rear-connector motherboards, the kind with the sockets on the back. We do not build with those as standard, but the case is ready for it if you ever want one
• 🌬️ Case cooling: 2 × 120mm ARGB reverse-blade side intake plus 1 × 120mm ARGB rear exhaust, all fitted by us
  Click or tap for deeper spec info

  • The 2500X ships with no fans at all. Not a reduced set, none. Every fan in this machine is one we have chosen and fitted, and that is a cost we absorb rather than a corner we cut
  • Reverse-blade fans on the intakes, which is a detail worth explaining. A normal fan shows you its frame and its wiring from the front. A reverse-blade fan is built the other way round so the blade face is what you see through the glass. In a case with two glass panels that is the difference between looking finished and looking assembled
  • Two intakes in the side position and one exhaust at the rear. Air comes in alongside the graphics card and leaves past the processor cooler
  • The bottom mounts are left empty on purpose. Fans will physically fit down there, but in this chassis they sit so close to the underside of the graphics card that they have very little room to breathe and contribute much less than the mount count suggests. We would rather fit three fans where they work than five where two of them are decoration
  • Worth knowing what fans are actually worth here: independent testing of this case found that adding fans was worth around 7°C on processor temperatures, while removing the glass panels entirely was worth about 1°C. The glass is not what limits this case. Empty fan mounts are, and this one does not have any that matter
  • Fan curves are set by hand before dispatch and verified through our standard stress testing rather than assumed
• ⚡ Power supply: Deepcool PL750D 750W 80+ Bronze, ATX 3.1 certified
  Click or tap for deeper spec info

  • 750W is far more than this build draws. That is intentional. A 7500F and a 9060 XT together pull well under 300W in normal use, so the supply spends its whole life in the quiet, efficient middle of its range rather than working hard
  • The real reason for the headroom is upgrades. This unit will run an RTX 5070, an RX 9070 or an RX 9070 XT without being replaced, so a graphics card upgrade in two years is a 15 minute job
  • ATX 3.1 certified, which means it is built to handle the sudden power spikes modern graphics cards produce without shutting the machine down. All PC36 power supplies of 750W and above are ATX 3.1 certified
  • Fixed cable, with the spare length folded into the rear chamber behind the motherboard tray, where the glass never reaches and nothing blocks airflow
  • Deepcool back it with a 10 year warranty
• 🔌 Cabling: Black cabling, routed into the rear chamber
  Click or tap for deeper spec info

  • Black cables throughout. Everything is routed through the tray's grommets into the right-hand chamber and tied down there, so the glass side shows the components and nothing else
  • This case rewards doing that properly and punishes not bothering, because two glass panels means there is no bad angle to hide behind. It is where a good share of the assembly time on this build goes
  • Braided cable extensions in a colour of your choice are available. See the upgrade options below
• 📶 WiFi / Bluetooth / Ethernet: Wi-Fi 6E, Bluetooth 5.2 and 2.5 Gigabit Ethernet, included
  Click or tap for deeper spec info

  • Built into the ASRock B850M Pro-A WiFi. No separate adapter needed, and the aerial is supplied in the box
  • Wi-Fi 6E adds the 6GHz band, which is usually far less congested than 2.4 and 5GHz if your router supports it
  • 2.5 Gigabit wired Ethernet, which is faster than the gigabit ports fitted to most boards at this price and worth having if you move large files around a home network
• 🪟 Operating system: As chosen by you from the listing options below. Windows 11 Home (OEM) is recommended.
• 🧹 Setup and optimisation: PC36 High-Class Standard. Full stress test with certificate, bloat-free installation, and BIOS set up properly
  Click or tap for deeper spec info

  PC36 High-Class Standard, included free with every build

  • Ready the moment you open the box. Your PC boots straight into Windows with a local account already set up. No account sign-in wall, no first-run questionnaire, no half-hour of setup before you can use the machine you just bought
  • BIOS updated and configured properly: manual fan curves, PBO enabled, EXPO enabled, Secure Boot enabled
  • Vanilla Windows 11 installation if you choose Windows, with no bloatware added by us, and all drivers loaded and ready to go
  • Full stress test with certificate. Every system is torture tested on CPU, RAM and GPU before dispatch, and ships with the certificate to prove it

  PC36 Premier Optimisation, available in the listing options

  • CPU tuning to bring thermals and noise down with minimal performance loss, plus a deeper strip and debloat of Windows and a hand-tuned fan profile
  • On this build it is a nice-to-have rather than a necessity. The 7500F is already a cool, quiet chip and this case moves plenty of air. It will make an already quiet PC quieter

  PC36 Ultimate Performance Tune, available in the listing options

  • Advanced overclocking: memory tune, CPU tune and GPU overclock on top of everything in Premier
  • Honestly, this is not the machine for it. At 1440p this build is limited by the graphics card, and a processor overclock will not change your frame rate. If you want more performance from Obsidian One, the money is better spent on the graphics card or on Obsidian Two
• 🛡️ Warranty: 3 years parts & labour (return to base)
  Click or tap for deeper spec info

  • Standard 3-year coverage included, parts and labour both
  • Optional extended warranties in the listing options below

👁️ Transparency notes

• Our photographs show the walnut version of this case, but every build now uses the plain black one, which is otherwise identical (click or tap to read more)

  Corsair sell the 2500X with an optional walnut front and roof, and that is what is in our gallery. It is no longer something we can source reliably, so every Obsidian we build now uses the standard black case, which is otherwise identical in every dimension and every feature. We are photographing a black build and the images will be replaced. Until then, look at the black case rather than the wood when you picture yours. If the woodgrain is specifically what you wanted, talk to us on live chat before you order and we will tell you honestly whether we can get one.

• This build uses single channel RAM, which offers a price saving but a very small performance loss (click or tap to read more)

  The gap against a matched pair is roughly 4 to 9 percent in processor-intensive games and close to nothing elsewhere, because DDR5 modules run two sub-channels internally rather than one. We fit one stick because DDR5 prices are high at the moment and the money is better spent on the graphics card. Three slots stay free, so adding a matching 16GB stick later gives you 32GB in dual channel with nothing thrown away. We can fit 2×8GB in dual channel from the start on request, though we would not usually recommend it. Ask us on live chat before you order.

• The glass is smoke tinted, which looks superb in a lit room and dims the interior in a dark one (click or tap to read more)

  If you want the lighting to read strongly at night, that is worth knowing before you order.

• Product images are representative photos of a similar spec in the same style. Your PC will look similar but not identical. Our support team can help clarify anything you're unsure of.

🛠️ Popular upgrade options

• Quick-add upgrades. This listing has a set of one-click upgrades chosen to fit this exact build, each one priced, in the Quick-add Upgrades section on this page. Memory, storage, optimisation, the anti-sag bracket and the extended warranty are in the build options instead. Anything not shown in either place, ask us on live chat and we will price it.
• Memory upgrade to 32GB (2×16GB) dual channel: available in the listing options below.
  Click or tap for more info

  The upgrade we would recommend first on this listing. It gets you dual channel memory as well as the extra capacity, so it is worth slightly more than the capacity alone suggests. Take it now if you stream, edit, or keep a lot open alongside a game. If you only play games at 1440p, 16GB is genuinely fine and you can add the second stick whenever you like.

• Storage upgrade to 2TB: available in the listing options below.
  Click or tap for more info

  Worth it if you keep more than about eight large games installed at once. Less urgent than on our higher builds, because two M.2 slots stay free and the rear chamber takes four more drives, so adding storage later is cheap and easy.

• Braided cable extensions: available in the listing options below.
  Click or tap for more info

  This is the listing where cable extensions earn their money. Two glass panels means the cabling between the power supply shroud and the motherboard is genuinely on show, and sleeved extensions change how the whole build reads. Purely cosmetic, but of all our cases this is the one where it shows most.

• Three slim 120mm intake fans in the base: available via live chat.
  Click or tap for more info

  We leave the bottom mounts empty as standard because standard-depth fans there sit very close to the underside of the graphics card and achieve less than the mount count implies. Slim fans change that arithmetic and give the card more room to breathe. On this tier the thermal gain is small, since a 9060 XT is not a hot card, so take it if you like the look of a full set through the glass rather than because the machine needs it. Ask us on live chat and we will price it.

• Graphics card upgrade: choose it from the quick-add upgrades, or speak with us via live chat.
  Click or tap for more info

  The 750W supply and 400mm of card clearance mean almost anything will go in without further changes. An RX 9070 GRE or an RTX 5070 is the natural next step. Talk to us and we will price it against simply buying Obsidian Two, which is often the better answer.

• CPU upgrade to Ryzen 7 7800X3D: choose it from the quick-add upgrades, or speak with us via live chat.
  Click or tap for more info

  Worth it only if you play CPU-limited games at high refresh rates, such as competitive shooters at 1080p or heavily modded simulation games. At 1440p with this graphics card you would not see the difference. If you want more performance from this machine, spend the money on the graphics card first.

• Extended warranty: available in the listing options below.
• Anything else: speak with us via live chat. Different fan colours, a white case, a bigger cooler, a specific card model. We build these to order, so most things are possible if you ask before you buy.

🎯 What is this PC best for?

• 1440p gaming at high settings in modern titles
• High frame rate competitive gaming at 1080p and 1440p
• Streaming and recording, using the card's AV1 encoder
• Anyone who wants the machine to be part of the desk rather than hidden under it
• Buyers who care about how a build looks inside as well as what it scores
• A sensible starting point on a platform and in a case that both upgrade cleanly for years
