Im building a new system. I am having confusion regarding correct psu. have a look at complete rig and suggest any alterations.

i5 750 (plan to overclock arnd 3.6ghz)


Coolermaster Hyper212+

G.Skill 4gb 1333 8-8-8-24 1.5V

HD 4850 1Gb (Powercolor or Sapphire)

PSU - Corsair VX450 or Glacial power GP-AL650AA (both around 90$, in india)

I already have -

WD 1TB FALS 7200RPM , LG DVD writer, Kb, mouse etc....

Is corsair 450 enough for this rig or should i go for glacial power...??
Also suggest any other component needing alteration...

The high quality Corsair VX 450 is an excellent choice. It can power your system.

The Asus p7p55d seems to be the more popular of the two motherboards.

Neither. Gigabyte P55-UD4P FTW!

As for the PSU, it is enough according to Corsair.

I would love to get this mobo, but unfortunately its not available in my local shop and secondly it'll put me back by around 280$ compared to 200$ for the other two(in INDIA)..

and regarding PSU, will the corsair be able to provide enough juice for OC'ing my rig and if i swap HD 4850 for HD 4890.... Just a thought..
