What power supply?

I am upgrading my computer. I am thinking about getting the i5 2500k processor and a motherboard to go with it. My current power supply should work as long as I choose a motherboard which has a 4 pin CPU power socket. This is the power supply that I have:
http://www.amazon.co.uk/600-Black-Storm-power-Supply/dp...
It is 600 watt and is very cheap!

I want to know if it is worth getting a new power supply. I am upgrading my PC because my processor has died. I have had my power supply and computer for a year and a half which I built. Is there any way the my cheap power supply can affect the life time of other components in my computer, for example my PSU. I believe that my CPU packed in because I had overclocked it by 10% and had unlocked the forth core. My processor is the Athlon II x3 3.2 GHz. Overclock to about 3.5GHz and a core unlocked. My motherboard is ASUS M4A78LT-M LE

If you do think that I should get a new power supply what one would you recommend. Like I said I am thinking of getting the i5. I have the HD 6850 graphics card and one hard drive. I was thinking of getting this corsair one:

However I notice that its only 80% efficient where others are 90%.

anything above 80% efficient is desirable. those 90% are extremely expensive.

corsair has a good reputation among PSUs.

Wow, you're not kidding. That thing is garbage.

Without question. The one you've got now is a time bomb.

Yes, a bad power supply can kill the other components outright, or reduce their lifespan. Also, I assume you mean "CPU" and not "PSU" because the power supply is the PSU.

Overclocking can decrease the lifespan, but 10% is nothing. I ran an E6600 at a 50% overclock for five years with no issues, and my X3210 is close to 100% overclocked.

That Corsair unit is pretty good. Certainly miles better than the one you've got now.

Yes, other PSUs are more efficient, but you're going to pay a lot more for that efficiency. 90%+ units will often cost twice as much as an 80%+ one. It's up to you to decide if it's worth it or not. Depends on how much you spend on electricity, how much power your computer draws and how much you use it.

Yes I would recommend getting a new PSU as the one you have looks very low quality and I wouldn't trust it.
It is entirely possible for a low quality PSU to cause damage/shorten the life-span/kill other components.
Overclocking and unlocking a CPU core could be the cause of pre-mature death, but the PSU could also have played a part.

This is better for the same price:
XFX Pro 550W Core Edition 80Plus Bronze £51

It is nice to have a unit which is as efficient as possible, but if you are on a 'lower budget' then it's better to prioritise performance (in terms of voltage regulation and ripple and noise suppression) and reliability.
It is possible to get an 80Plus Gold certified unit for close to £50:
