It is not as simple to add up the rails, typically total combined load would be max around 80% of that number so lets call yours 25amps! Most quality units will have that rating on the sticker in watts!
As you can see people are pointing towards replacing the unit ASAP I did not take that direction since you are planning to do that in the near future but I agree with them. If you try it and everything runs fine I still recommend replacing it but if you start experiencing sudden shut downs and other problems then do it ASAP!
Agreed. I can technically replace the PSU as soon as the 16-17th but I have to talk the wife into it lol. I just realized that Newegg accepts Paypal so I may be able to use the cash I have in there (if ebay ever releases it lol) and pickup a new PSU there or maybe ebay even.
Any recommendations on a $50-60 PSU that will do the job for my setup?
EDIT: Found this one with 2 PCI-E connectors, 40amp on 12v rail 520w Antec (http://www.newegg.com/Product/Product.aspx?Item=N82E16817371030)
think that one will be enough?
