How did you measure the voltage drop? (DMM I suppose?)

I replied in my thread... got this one off topic lol... but yes, i use a Fluke DMM along with some "old trusty" analog variants biggrin.gif

But you have to understand that Rail does not = Power and has nothing to do with it.
Its explained by the pros in this thread (in my sig too):
http://www.overclock.net/t/761202/single-rail-vs-multi-rail-explained
So having a 30A or 20A on the 3.3v rail doesn't mean that the 30A has higher power than the 20A or that it has better voltage regulation than the other...... or does it? not sure anymore...

This... lol I dunno. I'm working an RMA with PCP&C for mine, and I'm sure it will pan out ok.
