Which PSU?

post #1 of 10
Thread Starter 
Upgrading PSU, wondering which one you guys think would be the better choice between:

CORSAIR CMPSU-750TX ATX12V / EPS12V 750W

PC Power & Cooling S75QB EPS12V 750W

OCZ ModXStream OCZ780MXS ATX12V / EPS12V 780W

The Corsair and the PCP&C both have a single 12v rail and 60A on them, the OCZ has 4 12v rails with 20A on each.

It will be used with my sig rig.

I'd pick between the Corsair and PC P&C. JonnyG gave em both a rating of 9/10. If you don't mind the MIR definitely get the Corsair. I was on Jonny's forums a little bit ago and he was recommending this to be a good power supply and cheaper than both of those ignoring the MIR.

Why do I fell like an idiot for not being able to come up with what MIR means lol? Drawing a blank.

The XIGMATEK MC NRP-MC751 ATX12V Ver.2.2 / EPS12V Ver. 2.92 750W seems nice since its modular. Not in stock on the Egg however...

A tough call. I would go for Corsair 750TX, then PC P&C 750W.

AFAIK, the Xigmatek is the same "guts" as the TX750W. They're both CWT inside. My guess is Xigmatek is trying to saturate the market by under-cutting everyone else's price.
post #7 of 10
Yeah I can't seem to find any other reputable stores selling the Xigmatek. 'tis a shame.

So between the Corsair and the XIGMATEK I need to make my decision. Modular is attractive! But just not knowing who they are scares me. If JG says they are both made by CWT then I'll believe it.

Yeah. I can't find anyone else with the Xigmatek in stock either.

Another suggestion is the Thermaltake Toughpower 750W. Not as cheap as the Xigmatek, same price as the Corsair, but modular and from a company I think we're all familiar with.

Not to say the Corsair isn't a great choice.

I went ahead and ordered the Corsair. Should be here tomorrow. I also grabbed a CM 590 for another rig I'm building lol.
