you can link out a pin to trick the psu into starting unconnected

however i just went and bought a proper psu tester (thermaltake dr power 2)

and two of the four spare psu units i had here failed on the load test (secondhand not new ones)

heres a you tube link to testing ,rather annoying accent but does the job

I disconnected all the panel connectors from the mobo. Just using the power on switch on the mobo.
I think I have a volt meter but I admit I haven't ever tested a PS before. 
Being lazy here... is there a youtube vid that shows me how to do it?

I didn't think I needed to plug in the 6pin cause, as you said, its such a tiny vc and should just draw from mobo.
My older desktops are Antec Sonta cases with built-in PS... hard to get out. 
At the moment, I don't even have the Video card plugged in (although I have tried to boot with it in).  I'm just trying to get Dr Debug to tell me I'm missing stuff or what's wrong but I don't seem to be getting that far into the boot up process. Even if the CPU or water cooler were installed incorrectly, I would expect Dr Debug to tell me something.

sdlashley, have you tried the power on button on the board?  Please do, if not.  Do you have a volt meter to measure the voltages in the 24 pin connector?  Try clearing the CMOS.  I think you are seeing the V5SB (5 volt standby).  if all else fails, remove the front panel connectors from the board and then use the power on button on the board.  Perhaps you have a hot Reset due to plug error on the panel connectors.  You make a good point on the power supply rating, so do not get a new one yet, but you really need to measure your voltages when you get running.  Enjoy, John.

do you not have a spare psu you can test ?

even new ones can be faulty
(the old saying with electronics they either blow the first day/week or last forever)

i dont think that your drawing too much from it with your precise system

but do wonder why/if a 710 needs a 6 pin power (even 750's draw enough thru the pcie to run)

Since I'm not getting any Dr Debug codes, seems like its either the mobo or power supply. I might need to go buy another power supply and verify it. I am getting some power since the mobo does light up but maybe something else isn't working?

Actually, I did triple, quadruple, bajuple check them... and realized I didn't plug in the 6pin vid connector. But, that didn't help. I also tried this...
power off; unplug; insert 1 dimm into A2; press cmos clear; plug in; power on power supply; power switch mobo.
I repeated the process after insert 2nd dimm into B2.
Same result... led light under asrock gear turns green, then flashing blue. When I hit the power on mobo, I hear a click but nothing else happens.

The green & blue lights come from behind the gear logo on the mobo. 
Since I'm using such a weak video card and M2 drives and will never OC, the total draw on my power supply < 400watts so a 650w seems big enough. From what I've been able to search, this issue seems to be either the cpu power (4 pin) isn't plugged in or the board is bad. Just trying to make sure I try everything before entering the RMA process.

sdlashley, please see my signature for my similar build.  The first thing I see is the rating of your power supply.  I have an an additional 200 Watts.
Quote When powered on, first get green then flashing blue.
Where are the lights coming from?  Seems only the PS is even trying.  If so, I would ask PS support and check the PS manual.  What would you RMA?  I would borrow a stronger power supply and try again.  Enjoy, John.
