I just ordered a new system on Newegg and am unsure if I ordered a sufficiently powerful PSU. I assembled the system in my shopping cart a few months ago and decided to hold off on purchasing it until now. When I originally selected the components, I was not considering running crossfire or SLI, so I picked a Corsair 650HX modular PSU. Since the original selection, my budget has expanded, and I am now considering ordering a 2nd Radeon 5850 to run in crossfire a few months down the line. When I updated my shopping cart and made the purchase, I forgot to take the PSU and my possible future GPU purchase into consideration.
Will the current 650HX PSU be sufficient with two graphics cards (full system build below)?
I have already ordered all the parts from Newegg, and they should arrive at my house tomorrow. Should I return the 650HX before opening it and order a larger PSU if I plan to install a 2nd graphics card in the future? If so, which should I get? 750HX, 850HX? Will Newegg give me any trouble with this return?
Also, I got a $40 combo discount when purchasing the Corsair 700D case with the PSU. This same combo is offered for the 750HX, 850HX, 950TX, and 1000HX. Does anyone know if this would result in a complicated return procedure with Newegg? I really don't want to ship the case back.
