Common Applications
The N-PNY4090-X is purpose-built for the PCB of the PNY GeForce RTX 4090 24GB XLR8 Gaming VERTO EPIC-X RGB OC. A nickel-electroplated high-purity copper cold plate sits over the AD102 die, GDDR6X memory and VRM phases, sealed under a PMMA acrylic top. The black anodized aluminum backplate adds rear-side stiffness and thermal coverage without contacting coolant. Top and bottom G1/4 port pairs allow either serial or parallel routing, and an installed 5V 3-pin A-RGB (RBW) light bar provides motherboard-sync lighting. Bykski backs the block with a one-year manufacturer-defect warranty.
Frequently Asked Questions
Q: Which card is the N-PNY4090-X designed for?
A: PNY GeForce RTX 4090 24GB XLR8 Gaming VERTO EPIC-X RGB OC. Do not install on non-VERTO EPIC-X PNY 4090 cards; the PCB layout is specific to this SKU.
Q: What does the block cool?
A: GPU die, GDDR6X memory modules, and VRM stage in a single full-cover assembly.
Q: What materials touch the coolant?
A: Nickel-electroplated high-purity copper cold plate with a PMMA acrylic top. The aluminum backplate is dry-side only.
Q: What is in the box?
A: 1 full-cover GPU water block, 1 backplate, 2 stop fittings, mounting hardware, thermal grease, and 1 pre-installed 5V A-RGB (RBW) light bar.
Q: What is the warranty and is the loop aluminum-safe?
A: A full one-year warranty against manufacturing defects. The wet path is copper, so the rest of the loop must be copper or brass; no aluminum radiators or fittings.
