Oh, heavens, did I learn that the hard way. For my first water cooled rig, I installed water blocks on the mobo, CPU and GPU. Had the whole loop built, tested, filled. No leaks, no problems. THEN I plugged in all the power cables and tried to turn it on. Frickin' dead mobo. Had to drain and dismantle it all and ship the mobo back for a replacement.[/quotemsg]
That is rough!
I once gambled on a power supply and won. I bought a Corsair AX 850w power supply for a build a few years ago. The intent was to modify it. Cut the cables down to exact length for a micro-atx build and sleave the cables with custom blue and grey sleave. (this was before it was popular and you could get people to do it for you).
I was so excited to get started, that I cut the cables and got to work. I didn't realize until the day I went to put it back together that I had never even turned it on.
I'm still using that PSU as a daily driver 4 years later, but man was I nervous.
