Does the DFI LANPARTY UT nF4 Ultra-D require a 20 or 24 pin connection? Just curious, because either way the Antec TRUEPOWERII TPII-480 ATX12V 480W PS should be able to handle it, I believe. One question though, it seems to me that the Antec TRUEPOWERII TPII-480 ATX12V 480W and the Antec TRUEPOWERII TPII-480 BLUE ATX12V 480W Power Supply are identical except that the second one comes with blue LEDS. If so, why is the second one $10 cheaper?
