If it is enough...

You probably could run it without a problem because it does run 30a on the 12v rail. I'd actually recommend a little more juice though for 2 reasons. First, PSUs are most efficient near 50% of their capactiy. If you're running that 400cx in the 85% range under load, not going to be as efficient as it could and it can shorten the life of a unit running it near full all the time. Second, there's no room to upgrade with that tight of a margin.

I take it you're looking at the 400cx because of the rebate? While Corsair is a better product than OCZ, OCZ does have a good product. That corsair only carries a 3 yr warranty, same as the OCZ if that helps. Check these, they provide a little more room and are near the same price after rebates.

Yep😀 I'm a cheapo.


I guess I could take it up a notch and go for the...

As its only $5 more expensive than the corsair 450 watt.

If you can find something for cheaper feel free to recommend😀

I edited my post with a link before I saw this.

I have that 550VX, nice PSU that comes with a 5yr warranty. That would be better than the OCZs I have there, but like I said, OCZ is still a good enough product.

Hehe, I actually originally purchased http://www.newegg.com/Product/Product.aspx?Item=N82E16817341029&cm_re=ocz_power-_-17-341-029-_-Product

After installing it in my build I discovered it made a horrible grating sound when the fan spun >.<




EDIT:: http://www.newegg.com/Product/Product.aspx?Item=N82E16817341016&cm_re=ocz_psu-_-17-341-016-_-Product

Is pretty tempting though... I'll do a bit more research.

EDIT:: Going with OCZ... Willing to give it another chance!

PSUs are one component I would never buy recertified. If a PSU comes with a 3 yr warranty and doesn't have a little red voltage switch on the back, I'm okay using it for a quick pick. That recertified only had a 1, so even they knew it was a risk.

One thing OCZ does offer that others don't is a in route passing swap if there's a replacement needed. So you know you're getting a new PSU and not just your old one back after they took it apart and couldn't find anything.

Thanks for the best answer.
