Corsair AX1200w PSU Problem

post #1 of 4
Thread Starter 
Hello, new member here. I tried looking up any solutions on this site but had no luck so I figured I'd ask.

Bought a new Corsair AX1200w PSU a few days ago online. I heard it was one of the more premium PSU's available and a good investment. Received it yesterday and installed it, but when I went to power-on, it would turn on for 1 second then power back off.

I re-checked all of my connections, nothing. I cleared my CMOS by battery and by jumper. Nothing.

Any suggestions? Thank you in advance.

No, The older PSU that I had was functional (525w) but I just felt the need to get a newer and more advanced PSU so I could have sufficient power for future updates

Have you tried just powering on the psu and running it to see if its fully working and not something that is short-circuiting in your computer... if it turns out that the psu is faulty just rma it.

Just get a heavy gauged insulated piece of wire and insert it into the green wire socket and the black wire next to it, I have included a url on how to do this and this also tests the 3.3v, 5v, 12v to make sure that they are capable of outputting the recommended volts.

Note: Even though the psu will be converting full power to 12v still take precautions about electricity as it can be fatal.

How to test a psu:

I hope this has helped you.
