Trying to pick a PSU for my new I7 system

[kylo]

I need a modular PSU with at least 500w+

I have narrowed it down to these two but i can't decide which one is better...? Any tips or recommendations would be awesome.

SeaSonic X650 Gold 650W ATX12V V2.3/EPS 12V V2.91 SLI Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply - $160 (free shipping)

CORSAIR CMPSU-750HX 750W ATX12V 2.3 / EPS12V 2.91 SLI Ready CrossFire Ready 80 PLUS SILVER Certified Modular Active PFC Power Supply - $170 ($10 shipping)

Besides the obvious +100w difference... which one looks more reliable and efficient?

They are both very high quality units that I would trust. Both are manufactured by seasonic with the x650 being their newest and most efficient design as it is 80 plus gold certified. I would say get the seasonic if you're going to use a single graphics card the corsair if you plan on using dual cards. Either way you'll be very happy with your choice.

Yes. You cannot go wrong with either PSU.

The Corsair HX 750 is from CWT. Anyway, I agree with you.

Just FYI, that's a bad price on the 750HX. It used to be about $20 less. You could get the 850HX from Amazon for the same price without a rebate(the 750HX there is sold out).

Guess I'm used to saying that they are from Seasonic because of the older hx models.
