Advice - 3 pin XTX power connector

[randomguy1969]

Hey folks,

I'm looking at this card:

Asrock Radeon RX 7900 XTX Phantom Gaming OC 24GB GDDR6 PCI-Express Graphics Card

Order Asrock Radeon RX 7900 XTX Phantom Gaming OC 24GB GDDR6 PCI-Express Graphics Card now online and benefit from fast delivery.

It's got 3x 8 pin power connectors but can I get away with just two and the draw from the PCI Express socket? I plane on undervolting this too btw

Thanks

There are XTX cards with just 2 8 pins, I'd get one of those if you don't have enough.

If your psu doesn't have more than two pci-e connectors then it is not a psu that is suitable for a power hungry gpu. What make and model is the psu?

Heya.

Ok so it's bad I never realised thought I had a 750 w for some reason.....but it's a Corsair v650.

The Corsair VS series are garbage with cheap and nasty internals, are only basic 80+ white certified and should be avoided. Never skimp on the psu. Buy cheap, buy twice has never been more true than when buying a psu. The stock 7900XTX will draw up to 360w by itself when gaming with spikes up to 460w and that's just the graphics card. You are looking at a overclocked card that will have a even higher power draw. Asrock recommends a 1000w psu for that card although that seems rather excessive and I would say a decent quality 850w minimum although for the small price difference between a decent 850w and a decent 1000w you may as well go for the 1000w for future proofing and make sure it's ATX 3.0 as well.
