psu for gtx 560ti?

post #1 of 21
Thread Starter 
Hey guys,

I currently have a gts 450 and am looking at upgrading in the next few weeks to a gtx 560ti for more enjoyable gaming. I currently have a crappy 450W thermaltake psu and i know this won't be enough to run the new card and my existing hardware. What wattage PSU would i need to run this card and if you have an recommendations as to a specific PSU could you please let me know?

Many thanks

Depends on the model. A quality 450W PSU would be able to handle a 560 Ti. Do you have more information on your specific model?

well i have a thermaltake V3 black edition mid tower and the psu came with it, so i'm guessing it's not really very good.

There are people in these forums that will swear up and down that you can run a GTX580 on a high quality, name brand 400 watt power supply.

...but...

A good 500 watt Corsair with solid 12 volt rails should handle that fine. You will want something more like a 700 to 800 watt for SLI.

That TR PSU is crap, get a decent 550W-600W and you're good to go.

a decent 500w PSU is more than enough. im using a thermaltake 500w PSU on mine with cpu and gpu overclocks already and it still works great

Thermaltake power supplies are generally of high quality. It is unlikely the one you received free with the case was designed to do much heavy gaming. However, the recommended wattage for that card 500 watts. You would be cutting it close.

thermaltake power supplies are the same with budget FSP power supplies. they're decent but not that good still didn't stop me to use a thermaltake PSU on my htpc with gtx 560Ti. they're known to be very efficient cards anyway so even a thermaltake PSU will be good for the job
