  1. Unfortunately, the ATi Radeon HD 6870 requires 2 6-pin PCI-E adapters to run. My motherboard wouldn't even POST because the GFX card wouldn't even bother powering on. I'm very sure that many PSU's are capable of this, and alot of them actually are 6+2 pin adapters. Sorry, you will have to buy a new PSU for this graphics card.
  2. u don't necessarily need to buy a new psu.

    u should be provided with molex to pci-e adapters when u buy the card.

    if u don't have 2 spare molex cables, then ur out of luck. load and amperage balance are crucial as well.
  3. Your power supply unit should have a combined +12 Volt continuous current rating of 23 Amps or greater to properly power a Radeon HD 6870 system.
