Replacement psu for apparently dead Orion 900

[kbernatz]

Sadly, I did not do my homework on power supplies when purchasing a system from Vigor last October, and took their Orion 900 power supply. Today (6/2/2010), the system fails to start and I'm not getting power to any hardware (case fans, DVD, even the fan on the power supply itself is not working). I checked the power cord and it's fine, so my guess is that it is the psu. Researching the rep of the Orion psu, it definitely seems that it is a low quality component.

I have two GeForce 275's on an Asus P6T motherboard, in a fairly large case (Vigor gaming Deltaforce-T7 system case).

I would like to simply replace the Orion 900 psu with a comparable, but superior quality psu. One recommendation I found on-line was the Corsair 850TX (http://www.newegg.com/Product/Product.aspx?Item=N82E16817139009). Would this be a recommended replacement that should be fine with my other components? Is there anything I should be concerned about in purchasing a new psu? Thanks.

Corsair is a quality psu maker, If you are willing to spend the money and invest in this psu, I say go for it!

here's some data I compiled a few months back:

For comparison purposes , the list below contains performance ratings (10 scale) at jonnyguru.com / prices as per newegg on 02/21/2010 and ones w/ double asterisks (**) made it onto silentpcreview.com's Editor's Choice List meaning they excelled at both electronic and acoustic performance:

Thanks! Looks like I have some more homework to do, though I'm happy to see that the Corsair is a listed as a preferred option - given that it was explicitly mentioned as replacing the Orion 900.
