I’ll have to check to find the 4+4 pin that comes with it I’m not currently home right now but will update when I do in about 6 hrs from now, but I bought a 6 pin to 1x4 to 2x2 pin connector that seems to work with old psu so I don’t see why it wouldn’t with new one

The PUS cables are all very specific to each power supply, especially Corsair, so using there cables is very important.

CPU fans didn’t turn on at all just motherboard fans for sec then turning off, not sure what was the rating of old psu it was the default psu that came with computer

Okay, let us know what happens when you get home. Make sure you only use the cables that came with the Corsair Power Supply...

Using the 8 pin that came with the psu worked thank you for the help glad I didn’t have to pay 100 bucks to have someone come look at it
