EVGA 460 SSC and i5 760 on TX650

post #1 of 4
Thread Starter 
I have a fairly new Corsair TX650 and just bought a second EVGA GTX 460 SSC (actually the first card was a SC but over clocked to SSC speeds). From what I hear this PSU should be able to handle a second GTX 460, but will it be good for any extended period of time or should I keep an eye out for another PSU in the near future?

This is the same system in my sig. I keep all my overclocking on stock voltages but I do have fairly many things to power... 4 sticks (8 GBs) of 1.65v RAM, 7200 rpm drive, SSD, Sound Card, wireless NIC, DVD/burner, Logitech G110, Logitech G500, and external HDD.

Should I be planning to upgrade or will this last me a couple years?... I'm not really planning on adding anything to the system very soon.

Sorry forgot to put SLI in the title! As I stated above this is the second card.

You can easily power that rig even OCed with the 650W PSU for the longterm. Very likely it never goes over 500W, probably not even over 450W.

For your peace of mind you should think of buying one of these Kill-a-Watt measurement tools for 16$ on the egg (they could be cheaper somewhere else, got mine for 12). You plug it in the wall electricity socket and plug the PSU cable in it - this way you'll see in realtime exactly how much your rig consumes from the mains. Remember just that likely the PSU efficiency is about 80% so the amount of electricity supplied by the PSU to the components (where the 650W matters) is about 20% less than what's shown on the Kill-a-Watt screen, the 20% are losses in the PSU.

650w is more than enough for SLI GTX 460's + overclocks.

My system runs fine with a corsair cx400 so you will be fine with a tx650.
