I want to know that does this powersupply will work fine if these components are used.

The components detail is two (MSI) Geforce 8800GTX Graphic cards, (BFG tech) nForce680i motherboard, (Intel) X6800 core2Duo Processor, (Corsair) Dominator TWIN2X2048-6400C4D* memory, (westerndigital) Raptor X Hard disk, (Creative) Xi-Fi Fatality1 sound card and DVD writer and Combo drive.


Also a friend of mine told me to buy Corsair 620W powersupply. Is Corsair powersupply is better then mine Enermax Coolergiant 600W? kindly tell me in detail.

as long as it uses the same connector (new ones typically use 24 pin, older ones 20 pin) you will be ok... just double check that the connector on both the power supply and the motherboard are the same

as for which one is better, i have never heard of any of them, but if you google the make and model of the PSU and type review after it, you can compare both of them... i would find them for you but im in a bit of a rush, sorry

Hope this helps
