Will an Ultra LSP 550w work with gtx 560 ti?

Hello, I have been looking to upgrade from a sapphire vapor-x 5770 to a Gtx 560 ti.
My question is, can my PSU handle it?

I was stupid a few months ago and bought an OEM PC (HP Pavilion p6754y) with the intent to upgrade it, but i was even more of a novice with computers than i am now.

I bought an LSP 550 Watt PSU that (according to the box) has exactly 30 amps on the +12v rail, and 2 PCI-E 6-pin connectors.

I also bought a Sapphire Vapor-x 5770 and have been using it for a few months, but it gets quite hot (up to 85c in furmark, but only around 80~ in actual games). Although my friend bought the same PC along with a sapphire vapor-x 5750, and a corsair 650w PSU, and his temps are not nearly as hot as mine.

I have an AMD Athlon II x4 640 @ 3.0ghz, 4GB of what i believe is 1333mhz ram (but i may be wrong), and everything but the GPU was running off of a 250 watt PSU until i upgraded it.

My question is, would a GTX 560 ti work well with my system?

Ultra PSUs tend to be overrated, the 550 watt is probably closer to a 400 watt, not enough to run a 560Ti. I strongly recommend a better PSU for a 560Ti. You run a high risk of overstressing that power supply, the 560Ti uses about twice the amount of power of a 5770.

Alright, thanks. I figured this was the case because i have read some fairly bad things about ultra lol.
