I don't think they'd hang with the overclocking overhead the gtx classifieds possess.
The lights don't dim oddly enough with two psu's being run together. Just don't run you'r SS on the same room line as you're rigs. THat was my problem in days past, I ran an a/c unit, a/c chiller, two 1200 w PSU"s off one room line and constantly tripped the breaker. Got me braggin points for that
