Repeat PSU failures

[Catdaddy1958]

Hello,

I came back from out of town last week to find my PC inop. My PSU tester said DEAD. I tested another used one, installed it and IT DIED on connection.

I have since purchased a new case and PSU, reassembled the PC with only the DVD burner and the master HDD. INOP- PSU tests bad. (Did NOT test it before powering up- DID hear an arc when connecting the power cable.)

My question- is there a way to determine the component that's frying the PSU's without sacrificing another one and installing the components one at a time, stripped mobo first? I know I can test the HDD between a black and the pellow wire for resistance- what about testing the mobo, memory, etc, without sacrificing another drive?
AND- are there any protection fuses in a PSU that I can replace? I'm handy with a DVOM and a soldering iron...

Specs:
Homebuilt AMD 1900 on ATX mobo- forgot brand.
new cpu fan
used case fan
Toshiba DVD burner
80 gig WD whitebox HDD.
Don't remember memory mfg- been a while.

Well I don't know anything about power supply but you should really purchase from quality brands that use reliable OEMs to manufacture their parts. Seasonic has manufactured for itself, Antec, Corsair, and XFX. I would go for any of those. Other OEMs probably use crappy parts inside.
