    Will a Proline 500W PSU be good enough?

  6. If you hadn't said cheapest I would have said one of these two but the builder is fine and really cheap.

    The OCZ is modular with 3 yr cover and the Corsair has 5 yr cover, the builder series only has 2 yr cover.

    The IP-S500AQ3 Proline 500W Power Supply is actually made by IN WIN known more for their cheap computer cases.

    It has two +12 Volt rails with each rail rated at 17 Amps individually or 28.3 Amps combined.

    This power supply has only one 6-Pin PCI-E Power Connector.

    Your Radeon HD 6870 graphics card will draw a maximum of 14.1 Amps under full load. This graphics card also has two 75 Watt 6-pin PCI Express power connectors that must be used to evenly distribute the DC current draw.

    That Proline 500W Power Supply doesn't even meet AMD's recommendation of a power supply with two 75W 6-pin PCI Express power connectors for your HD 6870 graphics card.
  8. Will a Thermaltake 500W with dual 12V rail (36A combined) PSU be good enough?
  9. What is the minimum Amps per rail that can handle my system?

    Is there a reason why you don't buy one of the psu's recommended to you.

    You keep coming back with sub standard options??

    Corsair, Seasonic, XFX, OCZ a decent branded 500w will be plenty for your setup.
