Sure go ahead, if you have your digi cam handy.
Both of my Enermax psu's have 2 x 4 pin connectors, I think the mini atx FSP one in my media centre does too.
Edit: I just looked up that PC Power & Cooling psu (assuming that is the one you bought) it does indeed only have a 4 pin cpu power connector, the 6 pin is for a graphics card. You 'should' be able to run just using the 4 pin plugged into the 8 pin socket, making sure that it is plugged into pins 1-4 not 5-8 ...your motherboard should have something in the manual about this, for compitability with old psu's.
I am staggered that, that new power supply does not feature an 8 pin cpu power connector and a 6+2 and or 8 pin vga power connector though.
