Is this a reliable PSU - like the fact that it's modular and the name brand isn't half bad to me. I'm a kind of sucker for good deals - though I will only stick with the more common named brands. I think Thermaltake is relatively reliable because they make some slick cases and decent cpu coolers. Help me as I need to decide whether I should return this PSU for a 800w corsair or a 750w antec. Thank you!
