This motherboard has an 8pin,a 4pin EPS,and 24pin CPU connection. I purchased a 850 watt Thermaltake PSU that had a 8 pin and 24/20pin connection but no separate EPS 4 pin so I returned it to Newegg.com.I see some of the new PSUs have the 24/20 connection and two split 8 pin<4&4> connections. .I assume all of these connections should be utilized simultaneously on this motherboard<8pin 4pin and 24pin> is that true? The instruction manual is not very clear on this at all. This ASUS motherboard was given to me by a friend who is a gamer.Thanks for any help on this.

That's an overclockers board so I imagine the extra 4 pin is just for stability when pushing high clocks. I'm pretty sure you can leave that not hooked up.Edit: Looked around some and it seems I'm right about the extra 4 pin it's only for stability when pushing high clocks so you don't need to hook it up.
Thanks very much for the reply. This motherboard came with an 8 core AMD CPU and 32 gigs of RAM. I will be using a liquid cooler with a SSD 250 gig boot drive for Windows 7. Would this PSU be adequate since it has those 8 pin and 4pin eps connections:850 watt psu? Thanks again.

A 850W power supply should be more than adequate unless you are going to run multiple power hungry video cards and overclock everything. There are plenty of power calculators out there to help determine what you need.
