Specs: Windows Vista, AMD athlon x2 2.7GHz dual core
i have replaced the power supply in my PC twice.i started with a 350 watt,when that blew i went to a 500 watt,when that blew i went to a 650 watt power supply.i have a AMD athalon x2 dual core ASUS M2N68-VM mother board 1tb HD with a Nvidea 8800 gts video card.the 650 watt has been great since i got it about 2 years ago but it just shut off the other day while i was just reading news on the internet.i wasnt playing games or watching videos...does this sound strange?..what should i get for me next power supply..if 650 doesnt cut it should i just get the biggest they make,or is there another problem i should address before replaceing another power supply?

Purchase a better quality, look for single 12 volt rails and 80% efficiency certified power supply.
Have the power you plug the computer into tested, Problems can be:
A badly wired outlet.
Improper grounding.
Other wiring problems back as far as the fuse/breaker box.
Use a surge protector (or better yet a UPS) to plug in your computer hardware into.

You have to be a little bit crazy to keep you from going insane.

What you haven't told us is what brand and quality of powersupply have you been using? If you pay cheap you get cheap. A good quality 400W powersupply will outlast and outperform a cheap 750W unit.

The unit you had for the last two years.... Had you ever cleaned out the dust buildup from it's internal fan?

Just posting the wattage tells us nothing about the quality. My guess is you're buying cheap generic junk.

"the last power supply i had was a diablotek"

Diablotek are junk. Are you unable to buy online? Here's a Corsair 600W for just $40 after promo code & rebate:

http://www.newegg.com/Product/Produ...

Don't let the low cost fool you, Corsair is top quality. Notice the specs: ultra-quiet 120mm fan, Active PFC, 80 PLUS Certified, +12V@40A, extra long fully sleeved cables, 5 yr warranty.

What makes you think it's a problem with the power supply?

Something must be causing it to blow.

Or perhaps you think when a fuse blows you stick a 6" nail in it's place.

A thank you would be nice, if I have helped.

You're obviously clueless about power supplies. That fact that you bought a Diablotek confirms it.

Replacing a psu with a bigger one each time is the equivalent of fitting a 6" nail or higher rated Circuit breaker.

But ok, I'm sorry for my facetious comments.

As to the problem. The only thing I would suggest as it's so intermittent, is replacing parts one at a time.

I googled for common causes, http://www.google.co.uk/webhp?rlz=1...

Not sure if that will be any help.

A thank you would be nice, if I have helped.

if i knew it all about power supplies i would'nt be asking this particular question so dont get all uptight about comments i listed by people who have already bought the corsair and found it to be a waste of money.i know the diablotek isnt top of the line but it was affordable.and not wanting to waste my hard earned money on another piece of junk im asking people who might know.and now that i know diablotek is junk i wont be buying another one.

Look here:
http://www.newegg.com/Product/Produ...
I used certain search criteria like 80% bronze cert., single 12V rail, Active PFC, and arranged by Best Consumer Rating. Look especially at the XFX and OCZ. That is how I narrow down my search for quality components, then I look at the wattages, 12Volt Amperage, and prices of my top 4-6 choices. This way you can look for any really good buys only among the really good products.
