just wondering, if u don't have enough power to feed a graphic card, will it damage the card?
since im thinking of getting a 7600GT AGP while sticking to the old Icute 450W (dun think is real power, i doubt it only delivers around 250W++), wut consequences will i get?

P4 3.0GHz
1.5GB Kingston DDR400
FX 5600 AGP

It will slow down the card, the whole system and might overload the PSU and might fry the whole system with it. But your 450watts PSU is enough for your system. So I don't think you'll needing an aftermarket replacement.

While it is possible that an overload of the power supply can occur that will damage your components, the more likely situation is your system will either freeze or reboot.

if the card does not have enough power when you turn on your pc it will notify you that the card is underclocked to prevent damage to it.

psu's usually pop like chuck said too.

i'd suggest you get a better PSU. Icute PSUs are almost like cheap bundle PSUs you get with cheap casings. Get at least an antec. 8)

just stick your card in and try it.

99% of the time, if there isnt enough power, your system will just reboot.

No the card shouldn't break...

But as with any power loss, you might lose data off the harddrives, if Windows for some reason is touching important data, like the registry.

Could be a small possibility of a surge to the system, if the PSU is really bad, but a few tests most likely won't hurt. and assuming that supply is OK, 400w is enough.

Since that PSU most likely doesn't have the special graphics card adapter, you should connect the adapter that comes with the graphic card, from two different lines, there's usually two separate coming from the psu, use both and you're safest possible..
