if you would have read the topic:"before making a post about a psu..."
you would notic that the raidmax psu's are on the blacklist...
but anyhow,if like your computer working,do not use the psu...
try to get a refund for it...
Some of the new Raidmaxes are OK because they're made by Topower instead of their older provider, Leadman. Unfortunately I don't know how to tell them apart, except for reading "TOP" on the big transformer inside.
regarding the question, IMO
its likely a suckers bet, even if they are "OK" supplies your likely overpaying for them
better to be conservative and go with "know good" high quality components than take a chance with the one component that if it is flakey can alternately fry everything else or worse slowly degrade components and cause intermittent hard to pin down issues
