Power Supply Big Enough?

Bought a new agp vid card to replace my dying A-I-W 9800, it's a EVGA 256-A8-N542-T2 Geforce 7600gs 256mb. Before I install it I'm wondering now if my power supply is too small for this card. It looks to be a no name "POWERUP LC-B400ATX"
Here's what it says on the sticker of the PS, hope it helps.

V- : VOLTAGE : CURRENT
INPUT : 115V- : 10A
: 230V- : 6A
----------------------------------:--------------------------
V : +3.3V : +5V : +12V :-5V -12V +5VSB
:------------------------ :--------------------------
OUTPUT : 28A : 40A : 17A : 0.3A 0.8A 2A
----------------------------------:--------------------------
MAX ; 220W : 240W : 1.5W 9.6W 10W
: 380W

Well, it's either testing it or checking if anyone have tried that combo already on the net.

I have a problem with lousy tire 5 PSU crashing the system while playing games, so I'm switching to a much better and more reliable PSU now.

Yeah I had the same problem, I had only a single +12v rail as you, and that was trying to power everything with mobo/all the case fans and other things in found in there + the power consuming 88000 GTS.

Basically this produced rails to drop amps down causing the whole system to crash while playing.

But then again it depends on what other parts you have in the setup as well. Check out this one:

Helped me to get a recommended total W estimate.

If I try installing the card and it's not enough am I at a big risk of damaging the card itself?

thanks for all your answers

Got the card in and running, so far no problems over 2 days, no thanks to my clumsy fingers.
