Recently I have been hoping to upgrade my old graphics card (HD 5450) to a GTX 560 ti, my only concern is my PSU and my other specs in my system. I know the "recommended" requirements for the GTX 560 ti is at least a 500w psu with 30a on the 12v rails. At the moment i only have a 450w psu with dual 12v rails(both 18a) that supply about 360w of power(30a, I may be wrong). I was wondering if the GTX 560 ti would run in my system, if it can how long can it run before the psu would fail on me.

Specs:
Intel Core i5 650
8GB DDR3 RAM
Radeon HD 5450
FSP450-60EP 450W PSU

Rails:
+3.3V: 16A
+5V: 20A
+12V1: 18A
+12V2: 18A

you are correct on your 12v rail and its amps

the question is if your PSU can actually deliver its stated power and for how long. in theory it should work but still, I would look into purchasing a better PSU.

At the moment I am on a really tight budget and my current psu is only temporary, I was hoping to upgrade my PSU in about 2 weeks. I was wondering if my system could survive that long with my 450w.

if i were you, i would wait even if for 1 year... if you don't have the money right now just hold until you save some instead of firing out your system, the 450W could do it, but i don't know if you have a garbage PSU or a good brand one. and away from that, if any load happens your GTX 560Ti will blow up....
