Bykski GPU Water Block and Backplate for Sapphire Radeon RX 7900 XTX Nitro+ (A-SP7900XTX-X)
The Bykski A-SP7900XTX-X is a full-coverage GPU water block engineered for Sapphire Radeon RX 7900 series graphics cards. The nickel-plated T2 copper cold plate covers the GPU chip, while thermal pads transfer heat from the onboard memory and power stages into the cooling loop.
Replacing the stock air cooler with liquid cooling lowers sustained temperatures under heavy board power and eliminates fan noise from the system. A clear acrylic top displays coolant flow across the 0.3 mm micro-channels, and an aluminum backplate braces the circuit board.

Warnings
Warranty is repair or replacement. All returns are accepted within 30 days, no questions asked. An installed or used item comes back at a higher restocking fee.
The top is acrylic. Tighten mounting screws evenly and finger tight - over-tightening cracks acrylic, and a cracked top is not covered. Installation removes the card's stock cooler, so never power the card without the loop installed and the pump running. Thermal pads go where the block has corresponding raised contact points; the die itself uses thermal paste.
No instructions are included, the installation illustration is in the gallery images. The manufacturer may modify the design, so the delivered product may differ from the images. Qualified users must install it themselves. The manufacturer isn't liable for damage caused by misuse, improper installation, noncompliant operation, or incompatible hardware or fluids. Use constitutes acceptance of these risks.
Customer Reviews
I didn’t buy this water block because of the BYKSKI name; it was the only one available when I bought the 7900XTX Sapphire Nitro Plus for a ROCm AI build. I mainly use EK and Alphacool for water blocks, and I would have bought one of them, but alas, this was the only one available. To start off, the **** holes do not perfectly align. The silicone thermal strips included in the kit were smashed in transit because there was nothing to prevent the water block from doing so. The documentation was unacceptable; there is a nut on the block that needed to be removed, or it would crush a part of the PCB, obviously meant for some other model of 7900XTX. There are way more screws and some types of screws not needed, which is confusing. The backplate has two different types of **** holes and only one type of **** for this install. My biggest gripe is that there was no reduced-size PCIe plate for the GPU after adding the water block. In systems with many PCIe slots, one reason people watercool is to make them available again. But if the PCIe plate is not replaced with a reduced-size version, the PCIe slots are still useless under the GPU.
I build a lot of computers, but I would say unless documentation, quality control, and attention to detail improve, it will be my last BYKSKI water block.
Fit perfectly and after plumbing up the cards own loop with a 480 radiator temps do not reach over 32c under heavy load while over clocked. Should have made the move to GPU water cooling sooner
Keeps the GPU cool as designed. Looks great.
Overall great product and cools really good
High quality and keeps my gpu cool for a good price
