Corsair AX1500i Fried?

[rustybh1]

After complete PC strip down, migration to a new case, rebuild and introduction of a custom GPU cooling loop, my PC failed to power up after initial start today.

Carried out some troubleshooting by disconnecting all cables (except power in) and the PSU self test worked fine. Then reconnected one power connector at a time and ran the self test, all good until I connected the main ATX connector and the self test failed.

Next I removed the PSU from the case, and ran through the self tests again, connecting one cable at a time, this time with the other end of the cables not connected to anything, and again all worked good until I got to the main ATX connector.

Finally I tried the 2 halves of the connector separately and the test failed when I connected the 14 pin half of the connector.

I also tried this with a 2nd spare cable I had lying around.

I'm guessing that somehow my PSU is fried, but I just wanted opinions as a sanity check.

And now my next question.......... Do i swap it out like for like, or try something different??

hmm. when you were testing it, did you plug the cable into the motherboard to test it? Or was it just plugged into nothing but the psu?

before you say the unit is fried...it may be faulting due to a dead short. check that the mb not grounded out do to a missing standoff or the mb hitting the mb tray or cpu cooler shorting the mb out or if it on tight. may want to pull the mb on a table see if the mb and power supply post. also see if the cpu cooler is on to tight.

I tried the self test with both the cable plugged into the mobo and also plugged into nothing at all - same result, fail.

Mobo is all good and the cooler seated correctly.

Could also be a bad cable, but that will be hard to confirm if it's the main ATX as you say because chances are you don't have another one laying around to confirm it.

Is it still under warranty? Corsair is usually pretty easy to deal with and they may cross ship another unit or rush a cable to try.

Yep, tried with a 2nd cable I have, same results.
