Hello friends, in the coming week i am upgrading my computer with a new graphic card, ram and hopefully Cpu(if comes in the budget).
My question is regarding my PSU if it poweful enough For all of the new specs.

Firstly old configuation:
Cpu :Intel Dual core E2140 @1.6Ghz(oc to 2.1 GHz)
Mobo:Intel G43 express Chipset(dont know the brand nothing written on it)
Ram:1Gb ddr2 667 mhz
Hdd:WD 320 gb
Gpu:---
PSu:CIL-PDYSSEY oct 2008 450 w(as written on it,dont think its good enough)

New Specs :
Cpu:Intel Core 2 Duo E8400 3.0 GhzOr Core 2 Quad Q8300 2.5 Ghz
Mobo:same-Intel G43 express Chipset
Ram:4GB DDR2 800 mhz
Gpu:Ati radeon 5670 512MB GDDR5
PSU:same or if required New (want some suggestions)

I used to play games like Far Cry 2 with old specs with 15-20 fps.But sometimes(often many times) games suddenly freezes and the computer restars.Is it because of the PSU or something else.This happens even in games like Halo1.
I forgot to mention the frequency of ram goes up to 834 Mhz.
I want your expertise regarding the issues.

Your symptoms sound like a classic bad PSU scenario.

I've never heard of that brand of PSU. I suggest you get a new PSU from a good brand like Corsair, Enermax, Antec, Seasonic, PCP&C.

Your current PSU is borderline with that proposed configuration. I would jump to at least 620 watts. There are various opinions on PSU's. Go with one of the brands rwpritchett has recommended.

A good 450 - 500 watt PSU will power that system.

My favorite PSU for a mid-range system is the Corsair 550VX.

If the PSU is a good PSU
450W can even still handle a non-OCed Q8300 and a HD5850.
But 550W is more recommendable, so that you have some room to breath.

Corsair, Antec, Tagan, Silverstone, Seasonic, Enermax, and PPC make good PSUs. choose one from them.
