NVIDIA’s next-gen GeForce RTX 4090 graphics card, which will be powered by the AD102 “Ada Lovelace” GPU, will have a TBP (typical card power supply) of 600W…and that’s in reference form, not custom AIB form where 600W+ might be in the rearview mirror.
The rumors come from Tom @ Moore’s Law is Dead, who said his sources have confirmed the 600W power consumption news. AMD and its next-generation RDNA 3 architecture.
Tom’s sources explained: “It looks like the best Lovelace Professional 6000/8000 card could use 320-375W. Right now they’re testing prototypes at the limits of an 8-pin EPS (375W), or they’re even testing some prototypes with a 16-pin connector. It’s still 2 slots, and still a blowing cooler. So they’re limited to what they can cool“. The source added: “But this is an unprecedented power boost for a standard class of professional card.“.
The leaks continue:In mid-2021 the Lovelace top was expected to be a 400-500W card, but 500W+ was still an option…at this point 500-600W seems incredibly likely. The RTX 4090 will have a TBP of 600W. It also seems to be more advanced than the other maps…so it’s probably the first to launch“.
What about system integrators (SIs) and OEMs and the next-gen GeForce RTX 4090’s 600W power draw? Tom spoke to some industry sources, who said: “Honestly, we (major OEMs) don’t see this as a huge challenge. Now we know we need to support 600W, and so we will“.
“If people notice…many OEMs are suddenly releasing larger chassis that include much better PSUs for a reason. We prepare ourselves. 1000W+ PSUs will soon be standard“.
