Run 2 GTX 460's on corsair 650tx? - Page 2

post #11 of 20
Just don't overclock.

You will not damage anything if you power dual 460s and PHII on that PSU. If anything the PSU will blow if it's inadequate. You'll be fine, seriously. The 650TX is a great quality PSU.

Even if you OC the crap out of all your HW the PSU will handle it.

Shouldn't have any problems with overclocking all of that on a 650w corsair PSU

Yes, it will do it, just not very safely, do you have 4 free molex connecters left on your power supply? it only has 2 6pin connectors and you'll need to use the 2-molex to 1-6pin power converter cables so make sure whichever card you buy has them in the box (I think most manufacturers include them.)
FYI, Nvidia will tell you not to run your cards with the molex cables for long periods. I don't know why, i have seen many cards run that way for years without issues but i thought id let you know.

There is no safety concerns with that psu powering a x6 and two gtx 460s.

Yes, ignore the others. A 650W will be more than enough and you'll be able to overclock the cards to your hearts content.

Will be fine, just hope you are ready to deal with HyperSLI/SLI hack to run SLI on that AMD board.

A 460 does not use 270 watts. Its TDP is 160w. Even with a healthy OC, a single card will not approach your estimate.

No. Just no.

I don't usually call people out on these things, but no.

A 460 is a 160w GPU, not 270w.

I have a 955 x4 (125w CPU) and a 460 Hawk with 1 HDD and 3 fans on a folding rig. Even with both the CPU and GPU running at 100% and overclocked with upped volts, it pulls 330w from the wall. Add a 2nd 460 and you will be around 500w.

Your PSU is just fine (I actually got my Antec 620w in case I upgrade and get a 2nd 460).
