and i just want to know how much power supply is required for this card ? I know on Manufacture's link i posted above it says 400 Watt or Greater, but i have 300 Watt supply ... so should i upgrade psu or is it enough for this card ?
It really depends on how much the rest of your computer consumes. I would suggest getting at least 500W.
Well my system is old, but i cant upgrade it rite now ... here are the specs:
Operating System
Windows 7 Ultimate 64-bit SP1
CPU
Intel Core 2 Duo E8400 @ 3.00GHz 39 °C
Wolfdale 45nm Technology
RAM
2.00GB Dual-Channel DDR2 @ 332MHz (5-5-5-15)

Hard Drives
233GB Western Digital WDC WD2500AAJS-75B4A0 ATA Device (SATA) 31 °C

So will it be okay or i really need to upgrade the PSU ?
