The Gigabyte AORUS GeForce RTX 5090 XTREME WATERFORCE WB is the water-block ("WB") variant of AORUS's flagship Blackwell card. Instead of a triple-fan air cooler or a closed-loop AIO, it ships as a bare PCB wearing a pre-installed full-cover nickel-plated copper water block with G1/4 threaded ports — meaning it is built to be plumbed directly into a custom open-loop cooling system. It is, in effect, the same top-binned GB202 board as the air-cooled AORUS Xtreme, but stripped down for enthusiasts who already run (or are building) a hardline or soft-tube loop.
Under the block sits the full NVIDIA RTX 5090 silicon: the GB202 die on TSMC's 4N process with 21,760 CUDA cores, 170 RT cores, 680 Tensor cores, and 32GB of GDDR7 on a 512-bit bus pushing 1,792 GB/s. Gigabyte factory-overclocks it to a 2655 MHz boost, up from the 2407 MHz reference spec, and the block actively cools not just the GPU but the GDDR7 modules and VRM/MOSFETs. A leak-detection circuit runs across the whole block and flashes an RGB warning if it ever senses liquid escaping.
This is a deliberately niche product. It is not for someone shopping for a card to slot in and game on today — it has no fans and no heatsink, so it physically will not cool itself out of the box. It is for the custom-loop builder who wants the cleanest install, the lowest sustained temperatures, and a factory OC, without sourcing and mounting a third-party block themselves.
Quick verdict: If you run a custom loop, this is close to the ideal RTX 5090: top-tier factory OC, full-cover block with VRAM/VRM cooling, whole-block leak detection, a gorgeous concealed-PCB look, and a 4-year warranty. The water block keeps the GB202 far cooler and quieter than any air card, unlocking better sustained clocks. Just remember you're paying a heavy premium over the $1,999 reference 5090, and the card is dead weight without a loop to run it. For loop owners it's a 90/100; for everyone else, buy an air or AIO model instead.

Performance & Thermals
Gaming & compute
As the fully-enabled GB202, this is the fastest consumer GPU on the planet — typically 25-35% ahead of an RTX 4090 at 4K and the only card that comfortably drives 4K 240Hz and high-refresh 8K with DLSS 4 and multi-frame generation. The 2655 MHz factory OC adds a few percent over the reference 2407 MHz card; expect roughly 115 TFLOPS FP32. The 32GB GDDR7 frame buffer and 1,792 GB/s of bandwidth also make it a monster for local AI inference, Blender, and pro rendering.
Thermals
This is where the WB earns its keep. A full-cover block on a properly-sized loop holds the GB202 dramatically cooler than air or AIO cards — well clear of the 80-90°C an air 5090 can hit under sustained load, with memory and VRM also actively cooled. Lower core temps mean the GPU sustains its boost bin longer and the fan-less card adds zero noise of its own.
Acoustics
The card itself makes no sound — there are no fans on it at all. Total system noise is whatever your loop's pump and radiator fans produce, which a good loop keeps near-silent even at full 575W load. This is the quietest way to run a 5090.
Power & OC headroom
It pulls the same ~575W TGP as every 5090 through a single 16-pin (12V-2x6) connector; budget a quality 1000W PSU. Because liquid cooling removes the thermal ceiling, this card has more real overclocking headroom than air models — once temps are out of the equation, you're chasing the silicon's voltage/frequency limit rather than fighting heat. Use a native 12V-2x6 cable and seat it fully to avoid connector hot-spots.
Pros and Cons
✅ Pros
- Top-binned, fully-enabled RTX 5090 with a 2655 MHz factory OC
- Pre-installed full-cover block cools GPU, GDDR7 and VRM — no third-party block to buy or fit
- Whole-block leak-detection circuit with RGB flash warning adds peace of mind
- Lowest temperatures and effectively silent card — best sustained clocks of any 5090
- Stunning concealed-PCB aesthetic ideal for show builds
- 4-year warranty (with registration), longer than the FE's 3 years
- Single 16-pin connector and clean, slim profile in the loop
❌ Cons
- Unusable without an existing custom liquid loop — no fans or heatsink included
- Large premium over the $1,999 reference 5090 and even over AIO models
- Niche: wrong choice for anyone not already invested in custom cooling
- Installation risk and complexity (fittings, coolant, leak testing) fall on the buyer
- Still a ~575W card — needs a strong PSU and good case airflow for the rest of the loop
- Resale and warranty handling are fiddlier than a sealed air card once it's in a loop
Who should buy the AORUS GeForce RTX 5090 XTREME WATERFORCE WB?
Buy this only if you already run or are building a custom open-loop cooling system and want the cleanest, coolest, quietest, factory-overclocked RTX 5090 without sourcing a separate water block. It's aimed at enthusiast and show-build PC owners who value sub-60°C GPU temps and a fully-concealed PCB. If you want a 5090 you can simply install and game on, choose the air-cooled AORUS Xtreme/Master, an AIO WATERFORCE model, or the Founders Edition instead — they cost less and don't require a loop.
Frequently Asked Questions
How much does the AORUS RTX 5090 XTREME WATERFORCE WB cost and is it in stock?
It typically sells around $2,549.99 in the US (seen at Micro Center and Best Buy), a premium over the $1,999 reference RTX 5090 MSRP. As a niche water-block SKU it's produced in lower volume, so availability comes and goes — set stock alerts at major retailers.
Can I use this card without a custom water loop?
No. It ships as a bare PCB with a pre-installed water block and has no fans or heatsink. You must connect it to a working custom liquid loop (pump, radiator, fittings, coolant) via its G1/4 ports. Without a loop it cannot cool itself and should not be powered under load.
What power supply and connector does it need?
It uses a single 16-pin (12V-2x6 / 12VHPWR) connector and carries the RTX 5090's ~575W TGP. Gigabyte recommends a 1000W PSU; use a native 12V-2x6 cable from an ATX 3.x/PCIe 5.x supply and seat it fully to avoid hot-spots.
How is it different from the regular AORUS Xtreme WATERFORCE?
The non-WB WATERFORCE is a complete card with a built-in 360mm all-in-one cooler you just mount in your case. The WB version is a block-only board meant for your own custom open loop. Same GB202 silicon and 2655 MHz OC — different cooling philosophy.
How cool and quiet does it run versus an air-cooled 5090?
Much cooler and quieter. A full-cover block on a decent loop keeps the GB202 well below the 80-90°C air cards can reach, while also cooling the GDDR7 and VRM. The card itself makes no noise; total acoustics depend only on your pump and radiator fans.
Is it worth it over the Founders Edition or an air AORUS model?
Only if you're committed to custom liquid cooling. You're paying for a pre-mounted block, a factory OC, VRAM/VRM cooling, leak detection and a 4-year warranty. If you don't have a loop, the FE or an air/AIO 5090 delivers the same core performance for less money and zero installation risk.
