Hello! I'm building my first PC in December but I want to buy a component this month in order to have a little more budget when I buy the rest of the components.
I was thinking of buying a 750w PSU but I'm not sure if it will be powerful enough. The new build would be something like this:

CPU: i7 950
GPU: 460 sli // 6870 CF // 69xx i haven't decided yet
HDD: Samsung spinpoint F3 1TB
RAM: 6GB

750w is enough?? I'm not sure if i'll SLi or CF right now but it's a future possibility and I want a strong enough PSU

If 750w is enough, which PSU is better??
- Corsair HX750W
- NZXT HALE90 750w

Thanks a lot for reading!

The corsair 750 PSU would be a great option for any of those combinations of graphics cards.

Agreed. And 750w is plenty for that rig and then some.

wow thanks a lot for the quick responses. I just have two more questions:

I don't intend to overclock but just in case, can do some OCing (for example pushing the i7 950 to 4.0 ghz) with the corsair?

Just out of curiosity why not the NZXT psu?

Thanks!

with a 750w PSU from either corsair or nzxt (both are good) you can OC your CPU, RAM, and video card. the system has an OC i7 CPU and GTX 460 in SLI. they hardly broke 500w in a stress test.


FYI. the antec 750w true powers are on sale on newegg.

Test System Specs
- Intel Core i7 920 (Overclocked @ 3.70GHz)
- x3 2GB G.Skill DDR3 PC3-12800 (CAS 9-9-9-24)
- Asus
P6T Deluxe (Intel X58)
- OCZ GameXStream (700 watt)

Yes, I agree with the XFX psu, the same performance and quality (slightly lower efficency than the Hale, doesn't really matter because of the lower price) at a lower price is always great.

Great, I'll go with the Corsair then.
I would go for the XFX Black edition but the problem is I live in Spain. That means I can't buy from newegg, everything is overpriced, and I can't find half of the decent brands/models (yeah, PC stores here suck XD)

But anyways, I'll go for the Corsair and many many thanks for your help!
