Weird Issue with PSU

Mcthommo · 23 Mar 2023 at 15:15

upgrading from intel system to an AMD one- watercooled and pc wont start if I have any peripheral cable plugged in. will turn on if only 2 8pin cpu, 24 pin and 2 PCIE 8 pins but no matter what cable I use for the sata/Molex cables, it simply will not start- I have replaced cables with like for like and still the same
Any ideas what to try next as pulling the rest of my hair out with this.
psu is Corsair RM1000x with AMD 7950x on Gigabyte Aorus Elite X670 AX, RTX 3090 and various Aquacomputer peripherals- all water cooled

Ignore it- was one of the AS kit that was creating a short on the case frame
Update: still doing it so I think it must be one of the AS periphs causing an issue

AS is Aqua Suite stuff but I think I have located the issue- the USB 2.0 layout on the mobo is reversed to the pin layout for the previous mobo so was creating an overload that way.

in a word, yes
