EVGA GTX 950 SSC on sale at Newegg, but requires an 8 pin connection instead of the usual 6 pin, and my PSU (ANTEC VP 450 with 18A each on 2 12V rails) has only 1 6 pin connector (card comes with dual 6 pin to 8 pin so no good for me) and no 8 pin. Could I use a dual 4 pin molex to 8 pin adaptor to power the card?

    Yes, you can use the adapter and it will be fine. Just make sure your PSU has enough output to power the video board.

    OK you can use that BUT as the other person replied make sure your PSU has the guts first. Then having been there and done that when you use the dual molex hook each to a different line. Why this makes a difference I am not sure, but rationally it wont be pulling a lot of power from a single line.

    My system Asus A88X-Pro, AMD A10-7700K, 16 gigs G Skill DDR3, 120 SSD, 1 TB, H50, w10 64, Corsair Gold 750. No overclock. Monitor setup: DVI to 24", DP to 24", HDMI to cat 6 transmitter to 52" tv. The DP is set to my primary monitor.

    Yup, as stated, use a 4-pin molex from 12v rail 1 and a 4-pin molex from 12v rail 2.  Don't use 4-pin molex power from the same rail.  Especially don't use 4-pin molex power from the same daisy-chain series of molex connectors.

    One thing to be aware of is that PSU is rated to put out a max of 360 watts on the +12v. So while it's barely adequate, I wouldn't plan on doing any serious over clocking.
