Sapphire 7970 Vapor X 3 GB Power Req

The box says they recommend 750W or more, but everywhere else tells me 650W 80+ Gold is plenty. Please tell me 650W will be sufficient.

  1. A good 650w PSU should be fine depending on the rest of the systems specs and if any overclocking is taking place. Post the system specs and the make on model of the power supply you want to use.

    Only want to overclock the CPU to 4.6-4.8, nothing major. Single monitor, no Cross Fire, no Multi Monitor set ups, no crazy 5 GHz+ Overclocks on the CPU, and I will prob. just use the boost on the GPU to OC it, but I may manually OC a little bit (just to learn how, since I will be doing this for a living soon).

    Reason I'm worried is because I've already bought the PSU and GPU. When spending 6 months planning my build, I never looked at the power requirements on the actual card, I got information from everywhere but. (reviewers, users, etc...) It's 80+ Gold so I hope it will be good enough.
  3. 650 watts is enough as long as it is a decent 80+ model with a fairly heavy 12v rail.

    Well as far as I know it's one of the best 650 Watts. Corsair HX line, 80+ Gold.

    I looked up the specs. It has 54 amps or 648 watts on the 12v rail.
    You will be fine.
