Creative X-fi extreme music
maxtor 160GB sata HD

sorry for hijacking this thread but would a 650w psu costing £27 wreck my computer even though it has all the standard protections and is 80% efficient?

and yes 650w sounds fine but 750w would be a wise investment as you will have allot more upgradibility.

Next time make a new thread.

And no, the PSU will pull only what it needs. It's good to have higher wattage because of that efficiency rating though. However, unless you're running a very high end setup even a Corsair 450 will work fine.

Any PSU costing £27 is pretty much going to be junk. Go with a name brand, a Corsair 550 would be a good choice, or even as Carbon says, 450W would be enough with a Corsair.

I've had an E7200, P45, and a ATI 4870 all running off a 450W PSU before and there was no smoke.

Dont get carried away with wattage. Lots of the cheapo PSU Makers quote high wattage, to mislead the uninitiated.
The ampage on the +12v Rail(s) is the figure you should be looking for. If the maker is shy about listing these, then it's probably junk.
If you check out the Corsair 650w, you will see the rating is 52A, which, as Carbon said is more than adequate, with plenty in reserve. The Corsair 450w delivers 33A and the 550w delivers 41A

If you are unsure, this Calculator on Corsair's website is quite useful, in deciding what PSU you need, for a specific system.

Also, make sure that there is not 4 rails on the 12V side, as that is next to useless. One or two at max.
