Causes of Power Supply short circuiting
Posted on 2005-04-27
I have a custom built system and everything was working fine for a few months. Recently, I turned the system on, I heard two quick beeps and then saw sparks fly out of the back of the power supply.
I dismantled the entire system and rebuilt it from scratch with a new power supply. I got the system to boot and I could even get into the bios (after resetting CMOS) but the machine wouldn’t boot into windows. The power supply blew again.
This was a very cheap PS, a Kyoto 420 W, but I didn’t want to risk putting a good one in and having that blow again. The original power supply was the one that came with the case, again probably not a very good one, but it did last a few months
Here are some quick specs:
