  4. Thank you, the thing is, i can get the PSU the i mentioned for 20$.
  5. A system with one GTX 680 requires a 550W PSU with at least 36A on the 12V rails and two 75W 6-pin PCIe power connectors. The PP-800 has 60A available on the 12V rails and 4 PCIe power connectors; it is electrically sufficient and has enough connectors for this setup.

    A system with two HD7850s running in two way CF mode requires a 600W PSU with at least 36A on the 12V rails and two 75W 6-pin PCIe power connectors. The PP-800 is also sufficient for this build.

    The PSU is one of the most important components in your computer - it makes no sense to spend several hundred $ on other components and then skimp out on the PSU. Going with a cheap/crappy PSU may lead to system instability and worst case scenario - the PSU breaks down and takes other components with it.
