Can my PSU handle GTX 560 Ti or GTX 460

post #1 of 32
Thread Starter 
Based on my research, GTX 560 Ti and GTX 460 needs 24A on +12v

And on the box of my 550 watt PSU, it says that I have max load of 14A on +12 v1, and 15A on +12 v2

I don't really know what v1 or v2 mean, but does this mean that my PSU is 29A ? because 14A+15A = 29A ?

This a photo of my PSU box



Also, I want to mention that I have 8800GTS 320MB and it says on the box that 8800GTS needs 400w and 26A on +12, and I'm surprised about this because 8800GTS use only one 6-pin cable, while GTX 560 and 460 use two 6-pin cable

it COULD work, but i wouldn't risk it. Either save your cash to get a new PSU and GTX460/560ti, as not to risk your entire rig.

Actually gxt460 is 160w and gtx560 is 170w. The 24a you mentioned may be a system number. A good psu always show clear numbers including combine 12v. I don't think you just add 12v together in this case. What model of that PSU? And what's else such as cpu in that rig?

I have a Seasonic 520w. It runs 8 fans, 4 hard drives, mcp355, core i3 @ 4.5ghz, GTX 460 at 900mhz. Your more than safe.

Seasonic quality =/= thermaltake quality

that's a generic PSU afaik. don't use it. even a cheap so-so 500w PSU would be more than enough for a gtx 460/560

edit: nvm so they're thermaltake PSU's. I think that PSU can handle the two cards.

Going to need more information about the rest of your rig to give a remotely accurate answer to that question.

If it is a decent 550w and your not running anything too crazy for the rest of your rig then I would guess yes it will be fine, if its a cheap psu then I would say no.

what brand/model is the psu?

edit:lots of post since i started to reply getting distracted at work FTL. That PSU should be fine even if it is a budget Thermaltake it should still be decent.

It will be lucky if TR2 550 unit can pull 25a on 12v. Q6600 stock at 105w already. It isn't much left for GPU. It may run but when the GPU like gtx460, gtx560, price from $130 to $250, probably is time to get a solid psu. It is just to protect your investment.
