GTX 560 ti

[UnderPowered]

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

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....
