The PSU which Blew was a 550Watt which came with the machine by default

not sure what the actual CPU Model No. is though.

550 is more than enough, the PSU that came with the PC would have been of standard quality and are not really up to todays components.

I ran 2 HD 5770's with this PSU click here another choice is click here but there are certainly plenty of other quality PSU's to choose from.

Only basic PSU would run that setup, but you are better buying bigger in Watts for in case of upgrades as the PC only uses what it needs, it will not consume much more in power to run.#

A Basic would be in the order of 350 Watts, if its a good one.

PS its graphics and Drives that use power

Don't forget each USB port could be suppling power to the accessories plugged in, add a little bit for that.

& also Ollyolly PSU recomendations look good and pointer to the Online PSU Calc appreciated. For some odd reason I was thinking I needed 750w for this machine. Will post back what I end up with, as his Nvidia PCI Express card is Kaput failed, depends on what relplacment card he wants.

Yes, the PSU you choose will depend mainly on what replacement GPU he goes for.

Tell him to get a good quality brand rather than a generic/low-quality one that may lure him in with its higher quoted wattage. With PSUs, it's not always about large figures - other aspects are also important.

The quality PSU makes are: Antec, Be Quiet, Corsair, Enermax, Tagan, OCZ (or PC Power & Cooling), Seasonic, Silverstone, Etasis, Zalman, Xigmatek, Akasa, Chieftec, BFG - & the 'better' models offered by Coolermaster, FSP, Gigabyte & Thermaltake. G

Remember my own PSU which kept tripping out the Fusebox in the house, eventually found out it was a new Coolermaster 750w modular PSU but took me nearly 2 months to diagnose. That was a fun end to 2009

  GaT7 16:43 15 Feb 2011

Audio~~Chip, unfortunately the quality makes get it wrong on occasion too! But I'd still trust one over a generic/low quality alternative. G

The GTX Card has 2 PCI Express Power points on the card corner,
