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

Rumor mill: In accordance with trade sources, Nvidia has shared its reference boards for the flagship RTX 4000-sequence GPUs, which might perhaps perchance also be referred to as the RTX 4080, 4080 Ti, 4090, or 4090 Ti, with its OEM companions.

Rumor mill: In accordance with trade sources, Nvidia has shared its reference boards for the flagship RTX 4000-sequence GPUs, which might perhaps perchance also be referred to as the RTX 4080, 4080 Ti, 4090, or 4090 Ti, with its OEM companions. It hasn’t delivered the GPUs themselves yet, but the boards are geared to luxuriate in 600W of vitality.

Numerous leakers with factual display screen records dangle these days talked about that they request the RTX 4080 or 4090 to dangle a 600W TBP (total board vitality). A better-kill mannequin, both the RTX 4090 Ti or some particular edition card, can also luxuriate in over 800W. But they’ve also connected several disclaimers to those numbers, noting that it be too early for proper important points to were finalized.

Igor’s Lab reports that Nvidia has instructed OEMs to take a look at the reference boards outdated to support them make their PCBs and coolers at the total 600W. No longer every 4080 or 4090 will necessarily luxuriate in 600W out of the box, but at the least some will turbo or overclock into that vitality bracket.

Igor’s Lab obtained an image of a reference board from a Chinese language OEM and confirmed its authenticity with two diversified sources (above). One standout characteristic became once the twelve slots for memory modules, which display that the GPU might perhaps dangle both 12 GB or 24 GB of GDDR6X memory, perchance the latter.

It also had a formidable 24 voltage converters, up from 20 on the Founder’s Version RTX 3090 PCB (shared between the GPU and memory). It outdated UPI Semi’s UP9512 controllers able to eight phases, so three controllers per allotment.

All those converters and modules are fed by one 12VHPWR connector, also referred to as the PCIe 5.0 vitality sail, which might perhaps perchance bring 600W by myself. Igor’s Lab notes that OEMs are designing PCBs that consume the total 600W, but, as talked about, that’s a ceiling, no longer some degree out. Each 12VHPWR connector will approach with an adaptor with four 6+2 pin Molex plugs, even though most vitality offers construct no longer approach with that many cables.

The insiders request Nvidia to reuse the 3090’s three-slot air cooler for the 4080 and 4090. In the period in-between, manufacturers are reportedly making ready 3.5-slot air coolers and pondering water-cooled alternate solutions identical to what AMD outdated for the RX 6900 XT LC.

In a most likely first, the 3090 Ti and 4080 are allegedly pin-admire minded, which manner they’ll consume the same PCB designs. Igor’s Lab speculates that OEMs can also be using the 3090 Ti to check their 4080 coolers and PCBs. So the 3090 Ti and the 4080 might perhaps perchance share substances.

A minimum of, the 3090 Ti is the trial rush for the 12VHPWR connector. Rumors display that the 3090 Ti will luxuriate in 400-500W looking out on the mannequin, a fluctuate that appears loopy compared with the RTX 3000-sequence but tame compared with the rumored figures for the RTX 4080 and 4090.
