[harakim]

Im Buying a new Rig , it is a average gaming PC around 40k and i want to know how i can know that what i need for my power supply ?
I meant to say is which will be the best power supply for my Rig ?

Motherboard: Gigabyte EP-45-DS3R
Processor: Intel Core 2 Duo E8400
SATA HDD: Samsung SpinPoint F1 750 GB SATA 32 MB
Memory: Corsair TWIN2X2024-6400
graphic : Geforce 9600 GT

For a normal home PC which only runs games occasionally, a 300W-400W PSU should be fine. For a medium to high-end PC which runs games frequently, I'd recommend 450W-550W. For an ultra high-end gaming PC, 600W+.
