Graphics card power cable issue

[hobib_ali]

i have the Zotac 4090 and it has 4x 8pin power cable connectors that goes in to one cable that then feeds into the card, its an adaptor

is there a cable that is smaller or neater for cable management

I cant see anything online, generally you can get the thinner cables that are easier to manage

anyone else got a 40 series with an aftermarket adaptor?

and apparently the 4x8 pin cable adaptor, 1 or 2 of them is redundant

they do that to servers, why do it to consumer graphic cards

so in theory you can use a 2x8 pin adaptor as long as it provides 500 or 600 watts?

I'm not sure I'd entertain the idea of thinner cables. With the amount of power these things can pull under load, thin cables will lead to them getting hot and cause a potential fire.

I don't know the specifics of whether you need all 4 connectors attached, or how they should be shared across different power rails. Ultimately I think you have to forgo a bit of neater cable management with a beefy card.

The problem is you'd be wandering out of spec - that adapter ends in a connector rated for 600W right? So to be valid, it needs 4 x 150W 8-pin connectors in.

Regardless of what your card is actually specced to draw, that is what the adapter needs to made like.

Cablemod global store has their own 12VHPWR Extension (adaptor) cable, as well as various PSU compatible 12VHPWR cables that go directly to the PSU (bequiet, Asus, Corsair, Seasonic, EVGA) if the PSU is ATX 3.0 compatible.

The advantage of their adaptor cable is that the section from the GPU to the 3 PCI-E 8 pin connectors is longer so you just see one cable inside your case with the rest hidden behind wherever your PSU sits. For a 4090 their adaptor cable (for older PSUs) only has 3 PCI-E 8 pin connectors rather than 4 but they claim that this is enough to supply the 600W maximum power draw.

They will also be selling 90 degree and 180 degree adaptor plugs in the next few months to help with the tight bends in some cases where the cable leaves the GPU but these are not yet listed or ready for purchase.

I got myself an ATX 3.0 power supply, which comes with one 600W plug directly from the power supply to the card, looks neat.

Basically the above.

I already have the 2 x 8 pin to 1 x 12VHPWR cable for my Corsair HX850i. Only problem with that is the cable is stiff and projects straight out from the 4080 I'm using so I'm waiting for Cablemods to release the 90/180 cable adapters.
