298570 2004-12-02 00:54:00 just wondering before i put the new one in , is there any thing from my computer that could have caused the psu to blow or is it a fault noone (22)
298571 2004-12-02 00:56:00 Probably a fault, just make sure you've got the tab set at 230V. You computer shouldn't be able to cause the PSU to 'break'. ~~~~~ s y ~~~~~ (2054)
298572 2004-12-02 01:02:00 hope so noone (22)
298573 2004-12-02 01:10:00 The only time I worry about any power supply I have built is the first time I turn it on. ;-)

That one that banged was probably getting its first turn on. Of course, the replacement one is getting its first power up, too. :D

Don't worry, there were probably 2 or 3 out of each hundred produced tested thoroughly at the factory. If there had been a real problem, the batch would have been held back. The manufacturer has a good name, but they have a failure rate, however small. You happened to get a bad one.

298575 2004-12-02 01:31:00 You could always connect the green and black wireds on the 20pin ATX header and turn the PSU on without connecting it to the PC. That way you can find out if its faulty without risking your PC, that if you plug it in and it goes boom you know its your PC at fault. Pete O'Neil (250)
298576 2004-12-02 01:59:00 how could the pc be at fault ? noone (22)
298577 2004-12-02 02:12:00 > how could the pc be at fault ?
God knows, but atleast by doing the above test you can eliminate it as a possible suspect.

298578 2004-12-02 02:20:00 i dont think my pc is at fault as the old power supply worked and it still does work noone (22)
298579 2004-12-02 02:27:00 Just plug it in. It'll work. ;-)

If you're at all worried, plug it in before you install it. It's the moment it "sees" the mains (from the switch on the PSU) and charges a big capacitor through a rectifier that bangs and flashes can happen. And if it survives the first time, it will go for a long time.

The parts that feed the computer are fairly tame. A computer fault can cause smoke losses from the computer boards, but the worst computer faults might cause the PSU to shut down.
