I'm a PC technician and have used several ATX power supply testers on at least two DOA Dells, so here's my quandary. The PWS tested good on both occasions(most recently with Dr Power II), problem is, They were both bad. Last week I even ordered a new motherboard(I now have to return) because I was fooled into believing the tester. Turns out it was the PWS! A new(old ) Dell PWS fixed the problem.
And Here's the kicker...I think The motherboard knew the PWS was bad and didn't/Wouldn't/couldn't power it on(Dr Power II powered it on just fine.).
Why did Dr Power II Lie to me?!? Whats going on?
