Tonight I powered up my "in the making" PC, minus it's CPU just to run the watercooling loop for a few hours. After setting up the CPU blocks etc (first time since the rebuild) I turned on the PSU and pressed power... it was then I noticed not a hell of alot was happening, and some smoke was slowly rising out of my Coolermaster Realpower 700
Tried again outside later incase it was a conflict with something else with the same results, the fan does not spin up, and you can just hear some fizzing. Any idea what is up? I have already emailed MicroDirect about an RMA but am curious as to what went wrong?
