Compatibility Question .

Solution


No, they will work fine. It's just that they may have problems when the CPU goes into C7 sleep state. Corsair has a pretty good explanation: http://www.corsair.com/en-us/blog/2013/may/haswell-compatibility-with-corsair-power-supplies


I've seen the term Haswell ready a lot, does this mean these don't function with Haswell CPUs?

I'd avoid the CX line of Corsair PSUs if I were you. This mid-range Seasonic is one of the best for the money. A bit more expensive than the Evga you were looking at, but it should last the life of any system... and more. https://www.amazon.com/Seasonic-S12II-620-BRONZE-SS-620GB/dp/B003BIEOCI
 
Generally for budget PSUs with high quality:
Seasonic Units are great
As are XFX (except for the XT) - they are actually made by Seasonic
For corsair the new CXMs are decent (grey lettering on the box, 450/550/650W) all other CX/CXM units are utter garbage
