Nearly all stock NVIDIA RTX 4090 graphics cards have a higher maximum TGP (total graphics power) for overclocking. There are models with TGPs below 500W (ZOTAC), but the vast majority have higher values. There are cards around 600W (Founders Edition, ASUS ROG Strix or Gigabyte Gaming). But there is also a model that exceeds this threshold.

Colorful iGame Neptune is a liquid-cooled RTX 4090 graphics card. The chip is located on the same circuit board as in the iGame Vulcan series, but its clock speed is slightly higher – 2640 MHz versus 2625 MHz. What’s really higher is the maximum TGP of 630W – 80W more than the Vulcan. This power consumption is the highest of any RTX 4090 currently available. Colorful recommends a 1000W PSU for this card.

Interestingly, increasing the TGP by an additional 80 watts did not affect the performance increase in any way. In the 3DMark Time Spy Extreme test, the card showed only a 0.7% increase.

Also, even though the card has a default TGP of 550W, the peak value seen with the NVIDIA PCAT power monitoring tool was only 470W. It is also worth noting that due to the complex water cooling system of the video card, there was a relatively high idle power – 47 watts.

In addition to using the 12VHPWR connector, the 600W consumption is also achieved with four 8-pin power cables with adapters. As Igor’sLAB found out, NVIDIA RTX 4090 graphics cards go back to 450W when using only three 8-pin cables. In the case of NVIDIA’s latest generation flagships, it will not be superfluous to pay attention to the power consumption of a particular model.
