Hey guys,

Wondering if i were to buy the corsair 650w psu, for my new build, if it would still be compatible with haswell when it is released?? http://m.ebuyer.com/257232

Ps. Is 650w enough for i5470k and a gtx 660 + room for upgrades in the future? Also im thinking of getting the corsair 300r case, will that fit all my components in?? http://m.ebuyer.com/351501

Thanks guys!

Unknown.

Due to Haswell's new low power states there is a fear that current generation PSUs cannot provide low power that is stable enough for the CPU to use. That could potentially cause instability resulting in BSOD I suppose.

Since Corsair PSUs are manufactured by either Seasonic or Channel Well (CWT), I would say that you should not worry. Especially if it is a Seasonic model. I think it may be PSUs of average quality and below which may run into issues with Haswell.

A 650w PSU should be fine for you build and it should provide enough headroom for future upgrades....

...unless you are looking at two nVidia Titans...

If this is a gaming PC, then you are better off with the i5-4670k since games do not use Hyper Threading.

Compatible? - I would say yes and only because you would be able to disable these ultra low power states in the bios and avoid the situation.
