Subsequent-gen energy connector for GPUs can deal with as much as 600W – TechSpot

Why it issues: Trendy GPUs have pushed the venerable Eight-pin Molex connector to its limits. Nvidia denounced it with this era’s Founders Version playing cards, which have a proprietary 12-pin connector; AIBs select between overstuffing hungry playing cards with three connectors or ravenous them with two.

A brand new energy connector, known as 12VHPWR, solves that drawback by delivering as a lot energy as 4 Eight-pin Molex connectors — 600W. It’s a part of the PCIe 5.zero normal, and it may begin showing on GPUs subsequent yr.

Some producers have already listed their 12VHPWR plugs and cables, therefore the images. However the credit score for a lot of the particulars goes to Igor’s Lab, which realized concerning the connector from energy provide producers and AIBs. The latter was relieved to be shifting on from previous Eight-pins.

As its title would recommend, the 12VHPWR connector has 12 energy pins/plugs. They’re three mm large, as an alternative of four.2 mm like Molex. It additionally has 4 tiny contact pins/plugs on the underside to hold sideband indicators and a latch on prime to safe the pins within the plugs.

Every of the 12 energy channels can carry a minimum of 9.2 A at 12 V. When all 12 channels are lively, it could actually carry a complete of 55.22 A or 662.4W. However it could actually’t be paired with GPUs that draw greater than 600W as a result of it wants ~10% redundancy.

Impressively, at 19 mm large, it’s solely a fraction bigger than a single Eight-pin connector. It does require beefier cables, although, made out of extra premium supplies.

In the meanwhile, there aren’t any GPUs that require the total 600W. The primary GPU that’s rumored to make use of the 12VHPWR connector is the (unconfirmed) RTX 3090 Ti, which could draw 450W.

However the connector could be getting used to its fullest earlier than you’d anticipate. AMD and Nvidia’s subsequent era of information middle GPUs are believed to make use of power-hungry chiplet designs, and be twice as giant as their present choices, which already eat 250-300W.
