I am planning a new build, and was wondering if I should go for the Corsair HX650 or the XFX 750w Black Edition, I don't really plan to overclock, but I do want high end components for the quality and longer lifespan.

Here are my build specs:

AMD Phenom II x6 1090t
Corsair Dominator GT 2000mhz 8gb
Asus Crosshair IV
32gb Corsair SSD
2x 500gb Seagate 7200.12
XFX 6870 Black Edition
Corsair H50
Asus DVD Burner OEM
3x 140mm LED fans

My question is which would be the better choice for long term upgrades like crossfire, and possible OCing. I know they both are well reviewed, but I am wondering which ya'll would recommend. Thanks

The Corsair HX series are excellent:

I don't have any experience with the XFX model you mention,
because I am very loyal to Corsair's PSUs.


http://www.newegg.com/Product/Product.aspx?Item=N82E168...

+3.3V@24A, +5V@30A, +12V@52A, -12V@0.8A, +5VSB@3.0A

Warranty: 7 years limited


From the specs above, the 650HX appears to have a single +12 Volt rail:
(cf. "Single +12V rail design providing up to 52A")

some folks prefer a single rail, because it doesn't require any attention
to cabling any of the 12V connections.

Compute Watts = Volts x Amps; thus:

+12V x 52A = 624 Watts (same as shown on the PSU's UL plate)

That's a LOT of 12V direct current! :)

Well the 7 year warranty is definitely something to consider, but about the rail, the xfx has 62amps on a single 12v rail, and also both psu's OEMs are seasonic I believe. I would prefer to spend less, as in the corsair, but if 650w isn't going to allow for crossfire or ocing in the future I may end up needing to go to 750w.

^ Yes, you are right about the PSU's OEM,
And IMO if overclocking on the cards and 6870 Crossfire, IMO the 750W would be better,...

I was thinking the same thing, but the TX750 is also the same price with a large single rail, plus both are not modular, which is what I was hoping for.

^ Multiple Rails when implemented properly are as good, also that TP is partially modular,...
But if you are fine spending more, then get the XFX 750W, without doubt it is a very good PSU...

If I will choose between TX750 and TP 750 - I will buy TP 750. Tried that one and it's good one.
