is my seasonic power supply faulty?

post #1 of 14
Thread Starter 
Basically my PC just turns off just goes dead by it self and im 95% positive it is the power supply because i did the paperclip short with green and black wire then hooked up to my multimeter to the yellow wire and it is 12.26volts, now here is the problem it basically turns it self on and off by itself probably 5 times within 10 minutes "i watched voltage drop from 12 to nothing" then after the 5th time or so it stays on and reads a constant voltage so it does this for orange and red wires as well? so is it faulty?

Do you have another PSU you could try? Just to make sure your not RMA'ing something for nothing.

What you've listed really doesn't say much.

I don't think is the motherboard because it worked for about an hour then it got worse and worse. With the PSU completely out the the computer with nothing hooked to it, and shorting green to black it still does this. Do you want a video of what its doing?

Okay. Sounds like a pretty good plan then.

RMA that sucker.

Maybe a short in your case?


That +12V reading is completely fine by the way.

Even though it drops to 0.5V?

When does it drop to 0.5V? You didn't say that.
