Same cord for both supplies, because I wanted to rule that out. I also tried different PCIE connectors and both had the issues at some point or another. The stability of the OCZ unit seems to be an issue - sometimes it works, sometimes it doesn't. I ordered the PSU Rvenger linked in a previous post so hopefully I have luck with that. I really could not afford anything too expensive at the moment but I need my system back up and running both for school work and my gaming addiction.
And also, if I can say anything about a PSU brand from personal experience, it is that I have 2 Antec power supplies that are well over 6 years old and they are still up and running powering somewhat modern components. Those damn things last. No more OCZ for me.
