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 https://www.youtube.com/watch?v=hMP_zqlgzDc |

OK... lots of progress.
I pulled the PS out and tested it with the EVGA test that comes with the PS. It worked. Also, first time I was the PS fan come on. So, I put the PS back in and plugged in the 24 pin and hit cmos switch. Whaaaat... Dr Debug came on. I swear I tried this combo. Next, turn off, unplug, plug in cpu power. CMOS, power on... Whaaaat... Dr Debug comes on and not only that, it booted all the way to the bios screen. Hmm... now I'm confused. OK... last plug... I plug in the 8 pin power connector, location 9 on the mobo chart. oops.. back to flashing blue. pulled it out I've added the vc, up to 64 gb memory and m2 drive; hit cmos, boot to bios... all appears working. So, do I not plug in the 8 pin power connector in location 9?

right we need some extra info here
now you have a 24 pin power that only connects to 24 pin your psu only has a 8 pin splitable into 4+4 and from evga website any other multi plug is a vga ............. so where the hell is the other 4 pin board power coming from ? Edited by datonyb - 29 Sep 2017 at 3:56am |

try the 8pin in board location number 9 and the 24 pin location 10
do not use anything on the 4 pin location 2 and check to see that boots there is also another board power connector called GFX_12V1 location 18 in manual this is an extra pcie graphics connector for board (this gets used when 4 graphics cards are to be used to boost the pcie slots) long story short i think by default were going in a loop right back to johns first reply i think you need to uprate the psu, when we get to the bottom of this saga for an extra cpu/eps 4 or 8 pin lead (the 750watt evga g3 has two sets of these leads) Edited by datonyb - 29 Sep 2017 at 4:10am |

24-Pin ATX Cable
(1)
8(4+4)-Pin EPS/ATX12V CPU Cable
(1) 8(6+2)-Pin PCI-E VGA Cable
(1) <-- using this for 8 pin connect at location 9 on mobo 2 x 8(6+2)-Pin PCI-E VGA Cable <-- don't use any of these Everything does appear to be working. Bios shows all voltages within tolerance. Ubuntu is currently loading. Should I be worried?

datonyb, perhaps sdlashley is out buying a power supply.
sdlashley, I am almost positive you need a power supply with a CPU 8-pin (4+4 is OK) AND a CPU 4-pin connector. A lot more power is not needed for the rest of the machine. Enjoy, John. EDIT: Just read your latest post. Hang in there and when you are stable, please run Prime95 and keep an eye on the voltages, temperatures (CPU in particular) and other variables such as power. I have AIDA64, but if you do not, please DL the trial version or get HWMonitor (free). Edited by MisterJ - 29 Sep 2017 at 4:33am |
