Hello gamers, this bad boy arrived today and it’s the first time I’ve encountered 3 PCIe power slots. I’m familiar with using 1 cable and using the daisy chained 8 pin to handle the 2 slots. Since my Gigabyte 80+ G 1000W came with 3 of these PCIe cables I’m assuming this setup is correct? I’m probably needlessly worrying that I’ll brick this.
To be exact, each cable is an 2+6 pin into the PSU while the opposite end is 2 (daisy chained) 2+6 pins. My worry is rooted in not being familiar with the daisy chained bits importance.
Is this really such a big of a concern? I just built a new system recently with 7900 XTX and Corsair RM850x as a PSU, and it came with only 2 PCIe cables with daisy-chain ends (ridiculous amount of SATAs though for some reason), so one of the connectors on the GPU is currently using that. Should I shell out for an extra cable? Corsair ones are ridiculously overpriced where I’m at, €23 for a single one.
If the card pulls more than 300w I personally wouldn’t be using a daisy chain.
You will probably still be fine on a card with three plugs across two cables.
It’s worse on cards with two plugs, like some of the 3090 and 3080 cards. That use 400+ w of power.
