Hi, guys. As I need another video card for my other rig, I'm thinking about retiring my gtx 260 from my main rig. There are bunch of articles here on Tom that make the gtx 460 a great card to me.

Here's my question, would my Corsair TX750 be enough for my main rig with dual gtx 460s? Although I feel like 750 isn't quite sufficient, I do find on nvidia website that this PSU will be able to support dual GTX 460 setting.

Also, 12V on Corsair 750W is 740W. I believe most PC components nowadays rely most on 12V

The 460 I'm looking at is Asus GTX 460 OC'ed edition

Below is my main rig spec
i7 920 OC @ 3.33ghz
EVGA SLI LE
OCZ 12GB ddr3-1333
2X1TB HDDs
CM Cosmos 1000 case
5X120MM fans

Thanks a lot for your advices in advance.

I think he already HAS the Corsair 750TX, not sure just going by the wording in his post.

if not Shadow is right, have a look at the XFX since with the promo code its a few dollars cheaper than the Corsair. I'd still opt for the Corsair but I fanboy them a little bit so I'm biased.

Get the non-OCed version of the card and do it yourself. You will get much better results and save $30.

Is that why the price was so high? I thought they just jacked up the price of the DirectCU, I was shocked when I clicked the link.

EDIT - Yeah, here it is.

Check out the stats on that XFX unit and on the 650HX. All the power ratings are exactly the same and they are likely the same exact unit as both are rebranded Seasonic power supplies.

I know.. I have a problem. :pfff: 

Didn't realize that XFX was modular though, I'd get it just for that. Regardless I'm pretty sure the OP has a PSU.

The 650HX is modular as well(and also $30 more expensive right now.)

Yeah, I was comparing it to the TX, not HX. I thought the HXs were Channel Wells, not SeaSonic, but I guess thats the only the 1000HX.

I'd recommend the 650W XFX PSU if it's cheaper, There still a decent brand and it's SLi/80+ certified SFAIK.

Thanks, guys

Yea, i already have a corsair PSU, was wondering if it will be enough for that setting

The reason I chose the OC'ed Asus is because Amazon has it for 210, which is actually cheaper than the non OC version, so why not?! Although they dont have it in stock yet, but I have time to wait. And I live in a place where newegg charges sales tax :(  so for me, Asus is the best choice
