Why it issues: Modern GPUs have pushed the venerable 8-pin Molex connector to its limits. Nvidia denounced it with this era’s Founders Edition 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 downside by delivering as a lot energy as 4 8-pin Molex connectors — 600W. It’s a part of the PCIe 5.0 customary, and it might begin showing on GPUs subsequent yr.
Some producers have already listed their 12VHPWR plugs and cables, therefore the photographs. But the credit score for many of the particulars goes to Igor’s Lab, which discovered concerning the connector from energy provide producers and AIBs. The latter was relieved to be transferring on from previous 8-pins.
As its identify would recommend, the 12VHPWR connector has 12 energy pins/plugs. They’re 3 mm vast, as a substitute of 4.2 mm like Molex. It additionally has 4 tiny contact pins/plugs on the underside to hold sideband alerts and a latch on prime to safe the pins within the plugs.
Each of the 12 energy channels can carry a minimum of 9.2 A at 12 V. When all 12 channels are energetic, it may carry a complete of 55.22 A or 662.4W. But it may’t be paired with GPUs that draw greater than 600W as a result of it wants ~10% redundancy.
Impressively, at 19 mm vast, it’s solely a fraction bigger than a single 8-pin connector. It does require beefier cables, although, made out of extra premium supplies.
At the second, there aren’t any GPUs that require the complete 600W. The first GPU that’s rumored to make use of the 12VHPWR connector is the (unconfirmed) RTX 3090 Ti, which could draw 450W.
But the connector is perhaps 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.
