Hi everyone,

First time posting here...need some guidance from u experience pc guys..
Currently, my casing + PSU is the so-called cheapo Icute ATX 450W and using Geforce 6600Gt..with stable results.

Wanting to upgrade to Galaxy Geforce 7900GS Super but worry that my PSU will not have enuff juice...  Eventhough the PSU states combined dual 12V rails are 32A ( 17A + 15A ), but somehow after reading numerous post...i have doubts now on the stated Amperage....

So had anybody out there successfully run the 7900GS with the ICute ATX like mine without power related problems ????

What about those sub RM200 PSU selling in Low Yat like enermax, cooler master brands..are they sufficient to power the 7900GS.

My current specs in PC have nothing much, just bare essentials for budget gaming.
My specs now:

AMD 64 Bit 3000+
Asus K4NE Mobo
1GB Ram
80GB Harddisk
1 DVD RW
6600GT 128 MB
ATX Icute Casing c/w 450W power.
Any recommendations and advice will be much appreciated. Thanks.
