Run 2 GTX 460's on corsair 650tx?

post #1 of 20
Thread Starter 
Buying another 460, you think il be okay with this psu?
post #2 of 20
The lowest corsair slizone is saying is a 750 (the one i have to be exact). There are some 650's on there....it's up to you, but be aware you may blow the PSU and end up needing a new one. It's better to over kill a little than undershoot.

if you had a sandy bridge i'd say you'd be fine but since you have a Phenom2 its going to run a bit more watts. one of my rigs is a 2600k on stock clocks with 2 6970s and it runs on a 650w Corsair so it should be fine as long as the PSU is actually rated at 650w. so many factors involved to give you a solid yes/no answer.

Many people told me 650W was okay for GTX 460 SLI and a X6. It ran well for a long time. I added a few slipstream 1900 fans and then my XFX 650W started smoking.

I believe a 650W would work b/c my GTX 460's were 900 core at 1.87V and my X6 was 1.55V at 3.9GHz. If you're really worried, then get a 700W or higher.

A high quality Corsair 650W is fine. You won't have any issues.

You will exceed 80% of the 12V rail with that
Each 460 uses about 270Watts under load
The Hard drives you have (Samsung F3's) will use about 5Watts per drive
the 650tx is rated to 624W for the 12 V rail
80% of that is 499.2V
you will be using 550W + whatever the motherboard/processor requires
Even on a 750 Watt power supply that is pushing it (720W 12V rail, 80% is 576W)

It will work, but you are in the" danger territory"

Because I already own the 650TX, I will say I am a little disappointed to hear that it may not power the setup. The last thing I want is to over load the PSU and damage something more valuable.

It will power it.

You could run two 470's and a sandy system on that and it'd do it.

It'll be just fine. Just don't run prime95 and furmark at the same time.
