What is 1 x 16-pin?

[throwaway4372]

(The last time I built a pc it was 1x 8-pin and 1x 6-pin)

On this gpu spec sheet it says it takes a 1 x 16-pin:

ASUS TUF Gaming GeForce RTX™ 5070 12GB GDDR7 - Tech Specs

ASUS TUF Gaming GeForce RTX™ 5070 12GB offers ultimate durability and cooling performance with military-grade components and a phase-change GPU thermal pad.

On this psu spec sheet there is no mention of a 16-pin:

Can you help me make sense of this? How would I connect this GPU and PSU?

It's that abysmal new connector that Nvidia has been using for the last couple of gens. It should come with a adaptor in the box that you plug two or three pci-e 8 pin leads into but it looks bloody awful. They couldn't have made it look worse if they tried. They have made it far too short so that the sockets where the pci-e leads plug into are in full view and it just looks so untidy. It would have been better if they made it longer so that the connections could have been made behind the motherboard tray or psu compartment. That is the correct version of psu for the 5000 series and 1x 600W 12V-2x6 (12+4-pin) is what you are looking for. If you haven't already got it don't buy that psu as it isn't as good as the one it replaced plus they cut the warranty from 10 to 7 years.

The new connector began life as nvidia exclusive, with the 3000 cards.

It was later adopted as part of the PCIE spec and PSU manufacturers label their PSUs that carry it as PCIE5. This connector is: 12VHPWR.

The 12VHPWR is actually 12 pin, but 4 of them are sense pins positioned underneath.

It was updated again to what is called: 12v-2x6.

ATX 3.x PSUs have a modified spec that's supposed to account for the large power spikes from modern graphics cards.

If your PSU is ATX 3.x it will have the connector in some form, 12VHPWR or 12v-2x6.
