TX750 / HX620 ?

[whyzex]

Hey everyone,

Im going to buy a new pc very soon..
AMD Phenom 2 955 (3.2ghz)
Gigabyte MA790X-UD4P
OCZ (2x2gb 1066mhz) blade edition

And i was wondering.. would a Corsair HX620w will be enough for this system with two HD4890 or will i need the TX750w?
Thanks=)

I think a 620 would suffice but I'd personally go with a 750 just to be on the safe side, especially if you add a lot internal drives and such.

How many hard drives do you plan on using?

620HX should be enough and it's modular.

The HX620 would be enough, but I recommend this instead: http://www.newegg.com/Product/Product.aspx?Item=N82E16817371025

I use a PC Power & Cooling 750W Silencer Crossfire edition.
It's a little bit long for a PSU and features only a single rail.
If you want modular, the Corsair HX series has a top reputation.
The TX line is their 'value' line, so the quality might not be as good.
And I'm not sure if it's modular or not.

The TX line is not modular.

Im planning to have 1 hard drive and 1 DVD-RW drive..
so will a 620w be enough for 4890 x 2 ?
thanks =]
(btw the modular thing is just a bonus for me, i can settle for non-modular if its really good...)

Assuming that you're using a Core i7 CPU, as long as you do not OC whatsoever and only have one hard drive, the 620HX will be enough for two HD4890 in CF.

But I would recommend something beefier to be on the safe side. You can always get the 750HX or the 850HX PSUs if you want modular.
