Question Rog Loki 1200w/e870 crosshair USB power question

[littlelion4]

Hi Guys,
Im running into an issue with my PSU it has two 8pin connectors, my motherboard has two 8 pin CPU connectors which use these two up. The mother board also has and 8 pin USB power which i dont have space for on my PSU. So guys this is where i need your help, can i use a 6+2 on that 8pin usb power input under the ATX power input without toasting my MB? Heres the manual for help.

Ya i saw that but it does not tell me is I can use the 6+2 as an 8 pin. I'm gunna be hopefully grabbing a 5080 or 5090. And I have a ryzen 7 98003xd.

Yes, why not? It's the same like a 8 pin PCIe on a GPU where you use a 6+2 pin connector too.

But what case do you use. SFX and SFX-L have extremely short cables that can't reach the connectors on the motherboard in ATX cases.

Using the RoG Hyperion, and ya i grabbed cable extentions from cablemod for it. i just know your not supposed to use 6+2 for CPU i was not 100% certin if it was ok for any PCIE power or just direct to Graphic cards.

Use only the cables that come with the PSU.

Be very wary of extenders - verify that all of the pin-outs match.
