Is my PSU enough to use a gtx 650ti?

Hi, i was wondering if my PSU could run a gtx 650 ti, as it is kinda crappy. Some of the specs of the PSU:

-Omega, Model: 525ATX (Crappy brand)

-Total output maximum 525W

-It says something about having a couple of 12V rails, each one having 16A, it looks like this:
+12V number 1 16A
+12V number 2 16A

What do you guys think? can i buy a gtx 650 ti without worrying or should i get another GPU?

  1. That card needs 20 amps / 450w PSU to run, you are on the so called "safe" side.

    but i wouldnt trust that PSU..

    says a guy who ran overclocked 5850 + fx6100 on a sh** 500w 70% efficient psu... :D

    How do i know if i have the 20 amps? as i have a couple of 12V with 16A each, i really don't know how that system works :(

    Let me try and explain. Most p/s have one 12v rail rated at xxx amps from the p/s, some split that rail into two 12v rails like yours 2 16amp 12v rails. So the max rating on your 12v rail is 32amps. so you should be fine with 20 amps as long as there is no other big load on the second rail. There are some high end p/s that have two dedicated 12v rails but your talking high end parts.

    Now the bad news your power supply is probably only putting out about 60% efficiency or a little over 300watts of safe reliable power and that may be to little depending on your cpu and other peripherals.

    Thanks a lot for the explanation! So, would you recommend I take the risk of getting a gtx 650 ti? or should i get another GPU? If so, i would really appreciate if you could give me a couple of options please?
