My logisys ATX PSU has +12V max 16A on the +12V rail. I have +5V and max 36A on the +5V rail. That means I have 192W on the +12V and 180W on the +5V rail at Full/ Max load. I want to dedicate this PSU ENTIRELY (Nothing else plugged in) to a Radeon 6850 video card. The issue is I don't have an 6 pin connectors. Can I use a Molex to 6 pin adapter to power this video card? Will this PSU power my video card to begin with?
