Howdy folks , Just a quick one, I've got a Thermaltake 1200w PSU, it has 5 PCI-E 8 PIn connectors, my motherboard uses 3 of these and my GPU uses the other 2, I'm just gonna upgrade my GPU and that will need another 8pin can i use the daisy cable from one of the other cables as they split off to 2 at the ends? & Or are there PSUs that have 6 PCI-E 8pins on the back of them.
I'm confused on the PCI-e connectors used on the motherboard. Or do you mean the 8 pin motherboard connectors? The 2 are not the same (even though they can fit). The motherboard connectors will usually be split into 4+4, and GPU connectors split 6+2.
I would not use piggy back cables on that, no. Does your PSU have any extra connectors for EPS etc? it might be a better idea to have a third PCIE 8 pin made.
If the PSU is anything like this They all look like they have the same connector in the PSU body and there's only five of them. I have no experience of workstation boards but if they're gobbling up three of those slots it's only two left for the GPU and that's not enough for the xtx. But, yeah, I'd agree with @Vault-Tec - I'd not be daisy chaining on the 7900XTX
I've always been a bit wary of daisy chaining but then I've not had a clear reason as to why tbh other than the draw on one cable. In that scenario is there a preference to which would be daisy chained? I would presume the third connector on the GPU rather than the first but I have no idea why. Or does it make no odds?
It's more of a problem with thinner wires and cheap PSUs. Not sure which ones I'd go for, probably have to test to see if there was any difference, but it's normally pretty even.
The cables seem pretty thick gauge, I'm assuming they have the dasiy connectors for that reason but wanted to check my sentaments, I think it might be from the days of the old cheap PSUs with super thin wires, I can't remember the brand but one of my early pcs had a PSU that cost about £20.
This is the back of my PSU, I'm using all but 1 of the 6pin plugs with the included cables it came with, In for a penny in for a few pounds, Asus Rog Thor PSU ordered probably best not to cut corners
