I currently have a Rosewill Capstone 650w PSU. It's 80+ Gold and in the Tier 2 Class A section according to the list. I was wondering would it be enough to power a 4770k and 2x Sapphire R270X Vapor-X edition. I currently have an 8350 w/ a single 270x. I am planning on selling my 8350 and Asus M5A990FX Pro R2.0 soon since the single core performance isn't cutting it in some of the games I play. The PSU calculators I've used said it would be enough, but I just want some more opinions. Preferably from someone that has a similar system. Thanks.

for single card builds 450w-500w is usually more than enough; you might need 550w if doing big OCing. For SLI/Crossfire 750w is recommended.

Antec/Seasonic/XFX are the better PSUs to get. How long have you had the rosewill? if it's worked for a few months then it might be a decent one and worth keeping.

Edit: if it's this one http://www.newegg.com/Product/Product.aspx?Item=N82E16817182071&cm_re=capstone_650-_-17-182-071-_-Product
It looks good to use for a single card set up, might work for dual 270x to.

It should be ok. Most sites recommend 700W for that card in crossfire, but that's assuming a low quality PSU. You have a very nice one there (capstone is made by Super Flower, right up there in quality with Seasonic). Your 650W should be enough.

It even comes with 4 x 6+2-Pin PCI-E connector, which means they had CF/SLI in mind when they built it.

Yeah that's what I was thinking. Since I already have a single card, I just want to add another one instead of going through the hassle of selling and shipping the current card and getting a stronger single card.
