will this PSU be enough?

[soul_steel]

I'm looking for a new PSU for my pc, is not such a high end computer so I bought a corsair CX430 Power supply, but I aquired a radeon 5770 from my job and I want to load it to my system, I did some research and found it needs 34A in the 12v rail and the PSU only has 31A, so I want to ask if it will be able to told my pc? or maybe I got bad information and it can work with this PSU?

here's my system

AMD phenom 9650
4gb ram ddr2
biostar a760g m2+

that's all I have loaded, oh and my Hard drive as well.

is that enough or do I need a larger psu? thank you for your answers

They [ AMD ] reccomend a 450 watt psu with 1 x 6 pin

No mention of amps

An Nvidia GTX650Ti has a 400 watt reccomendation
http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-650ti/specifications
No mention of amps

Both cards have similar max power ratings
http://www.gpureview.com/show_cards.php?card1=615&card2=682

Both companies overstate what is really needed, to make up for cheap azz power supplies inability to provide enough amperage

You'll be fine

I'm using a GTX650Ti on a 220w PSU.
Those ratings are generally for terrible PSUs that cant manage to hit half their rated power.
