Why such on experiments with noname PSU? Why not take branded one?
I tried some on "named PSUs" / coolermaster / corsair / fsp / silverstone.
So far, the verdict is that I have no luck with Coolermaster / Silverstone. RMA them fast though it takes about 2-3 weeks for them to send me a replacement.
I'm also an idiot for running more than 4 vegas on a single mobo :-P
