Is 750W overkill for this build?

Achilles16 · Mar 10, 2014

I am about to start ordering parts for the new gaming system i am going to build. I was just wondering if 750w was overkill for the system i am going to be building. Keep in mind that i will over clock and probably do SLI in future. Here is the link to PCpartpicker and the specs.

I'd say it is good, because you should have enough room for SLI if you want with overclocking. I'd go with a 600w if you don't want that upgrade path or if you do go for a minimum of 850w.

More than enough power with this 550w

The CX Series are very poor supplies with cheap capacitors.

It isn't overkill no. It is definitely more than you need though. As someone else pointed out though CX series aren't really all that good; you can get much better PSUs for the same money that corsair charges.

I will be overclocking and probably be doing SLI in future too.

Would 550W be more than enough for overclocking and SLI though?

Any recommendations?

Seasonic S12G-550; is a much better unit than the corsair, and costs less. The XFX XTR 550 is good too.

That 550w XFX would be enough for overclocking but not enough for SLI.

Which XFX series is better? Are they both Haswell ready?

I have found these two but don't know which to go with.
