Nvidia is reportedly making 600W reference boards for the RTX 4090

Rumor mill: According to market sources, Nvidia has shared its reference boards for the flagship RTX 4000-collection GPUs, which could possibly be termed the RTX 4080, 4080 Ti, 4090, or 4090 Ti, with its OEM associates. It has not delivered the GPUs on their own however, but the boards are geared to eat 600W of energy.

Quite a few leakers with superior monitor data have just lately reported that they anticipate the RTX 4080 or 4090 to have a 600W TBP (whole board ability). A higher-finish model, both the RTX 4090 Ti or some particular edition card, could take in about 800W. But they’ve also hooked up a number of disclaimers to all those figures, noting that it is far too early for correct particulars to have been finalized.

Igor’s Lab reviews that Nvidia has advised OEMs to take a look at the reference boards employed to help them style their PCBs and coolers at the comprehensive 600W. Not every 4080 or 4090 will necessarily consume 600W out of the box, but at minimum some will turbo or overclock into that electricity bracket.

Igor’s Lab acquired a picture of a reference board from a Chinese OEM and verified its authenticity with two other sources (previously mentioned). One particular standout element was the twelve slots for memory modules, which indicate that the GPU will have either 12 GB or 24 GB of GDDR6X memory, most likely the latter.

It also experienced an impressive 24 voltage converters, up from 20 on the Founder’s Version RTX 3090 PCB (shared involving the GPU and memory). It utilized UPI Semi’s UP9512 controllers able of eight phases, so 3 controllers for each phase.

All all those converters and modules are fed by one 12VHPWR connector, also identified as the PCIe 5. electric power plug, which can provide 600W alone. Igor’s Lab notes that OEMs are designing PCBs that use the comprehensive 600W, but, as described, that’s a ceiling, not an regular. Every 12VHPWR connector will occur with an adaptor with four 6+2 pin Molex plugs, even even though most energy provides you should not come with that many cables.

The insiders anticipate Nvidia to reuse the 3090’s three-slot air cooler for the 4080 and 4090. In the meantime, suppliers are reportedly making ready 3.5-slot air coolers and looking at water-cooled solutions very similar to what AMD utilized for the RX 6900 XT LC.

In a prospective initially, the 3090 Ti and 4080 are allegedly pin-appropriate, that means they can use the exact PCB patterns. Igor’s Lab speculates that OEMs could possibly be utilizing the 3090 Ti to examination their 4080 coolers and PCBs. So the 3090 Ti and the 4080 may well share sections.

At the pretty minimum, the 3090 Ti is the demo run for the 12VHPWR connector. Rumors show that the 3090 Ti will eat 400-500W relying on the product, a vary that seems to be mad when compared to the RTX 3000-sequence but tame compared to the rumored figures for the RTX 4080 and 4090.
