deadlockedworld :
What retailers do you have available? A 400 or 450w quality brand PSU would be a better choice than a cheap 500w. I dont know what information you have, but the US newegg listing for the coolermaster doesnt even list the +12v amperage--and it costs as much as my Corsair did.
This is a much better deal at that price:

Also my configuration is,
Intel Core 2 Duo E7400 (OC to 280MHz x10.5 = 2.94GHz)
2x 2GB DDR2 800 Dual Ch. RAM KVR (OC to 420MHz)
ATi Radeon HD 4670 1GB DDR3 (OC to 850MHz core/980MHz memory)
ASUS G31 chipset m/b
Zebronics Platinum 500W PSU
1x Seagate Barracuda 7200.12 320GB and 1x WD Caviar Blue 160GB
Creative SB X-Fi Titanium & Creative Inspire T7900 (+ Creative SBS 560 with realtek)
2x DVD RAM drives
APC 500VA UPS
Samsung SyncMaster 793s monitor
iBall combo multimedia keyboard and mouse
Here's everything you may need for your opinion.
Will there be any problem if I upgrade to ATi 5770 1GB with Core 2 Duo E8400?
I have a pcie 1.1 x16 slot, a 5770 requires pcie 2.1 for full functionality
