Colorful formally released its flagship custom-design graphics card based on the GeForce RTX 4080 "Ada" launched earlier this week, the iGame RTX 4080 Neptune OC-V. This card features a factory-fitted all-in-one (AIO) liquid cooling solution. Unlike some other similar cards, such as the MSI SUPRIM Liquid X, the Neptune OC-V relies on a 100% liquid-cooled configuration, wherein a the cold-plate is the only source of cooling for the GPU, memory, and VRM; there are no additional fans on the card. The cooling solution involves a waterblock that pulls heat from all key components on the PCB, which is connected to a 360 mm x 120 mm radiator that comes with three 120 mm RGB fans.

The card is 25.3 cm in length, strictly 2 slots thick, and 17 cm in height. Silvery aluminium makes up the cooler shroud and backplate. The coolant tubing comes with white Nylon sleeving. The aluminium radiator has a white frame, as do the three fans. The fan impellers are frosted to act like RGB diffusers. The Neptune OC-V comes with factory-overclocked speeds of 2640 MHz GPU Boost (compared to 2505 MHz reference). The most interesting aspect is the power limit, which is now set at 470 W (compared to 320 W reference). This means that the 12+4 pin ATX 12VHPWR power connector has 600 W keying, and the included power adapter is of the 4x 8-pin PCIe to 1x 12VHPWR type, compared to most other RTX 4080 cards that include an adapter that's keyed for 450 W (3x 8-pin).
