So I was wondering if I would be able to run a HD 5850 on 430W PSU, it has 28 Amps on the single 12V Rail, which i heard was better than two lower amped dual 12V rails, I was hoping to Unlock my CPU(Will list soon-to-be specs of PC later), and if not, I would at least want to overclock it, though on stock voltage, I was hoping to use a two 4pin Molex to 8pin adapter and take away the two extra pins to plug into the card as the CX430 only has one 6pin though the HD 5850 needs two.I can't change PSU, as it comes pre-built with he rest of the PC.

CPU - AMD Athlon II X3 450 (3x 3.2GHz) 4000MT, 1.5mb

The card requires you to have a 500 Watt power supply unit at minimum if you use it in a high-end system. That power supply needs to have (in total accumulated) at least 40 Amps available on the +12 volts rails.
are you sure, my friend had that card, its that dual core card right, and he said he needed an 800 watt psu or something. He said it came otu recently but his job allowed him to have a test run of it or something at his job area.
