" rel="nofollow - Installed E5-2620-v3 or E5-2640-v3 with memory :
Video card is MSI GT 610. Nothing seen on the monitor. When the motherboard is powered on the first time, the PSU fan starts / the CPU fan starts. +- 5 seconds after, the PSU / CPU fans are stopping for few seconds then starts again. Nothing seen on the monitor... Is the card broken?

" rel="nofollow - Both CPUs and the memory are compatible. I just looked. CPUs are covered under "All' BIOS revisions and Crucial states that memory is compatible with your MB. You haven't overlooked connecting the 8-pin CPU Power have you? |

" rel="nofollow - Well that's the second issue I'm having.... When I connect both power connectors, the motherboard does not power at all.... What's wrong here?

Time to remove it from the case and bench it with just the bare minimum to enter the BIOS. CPU+cooler, memory, and an ol' cheapo PCIe GPU seeings those Xeons ya have have no iGPU. Peeking through the wire from here to all the way there I'm guessing it's shorting on something. Too, list out the components that comprise your system, including the PSU and its age |

Oh. Double check the case wiring at the MBs System Panel Header too. Some case/MB combos can get confusing. |

Hello, I'm using a new 400Watts powersupply Be Quiet! BN227 SFX Power 2. Even out of the case, the issue is still seen [ with or without videocard installed] Regards Olivier

" rel="nofollow - GT 610 min. is a 300w PSU. Question the PSU. With 24-pin it fires yet with 24-pin _and_ 8-pin it does as you say???? Makes no sense it acts that way. Swap in another PSU to test. |

" rel="nofollow - Can I assume yYou're experienced enough you don't question the CPU and or cooler install? The memory is FULLY seated? Not high on one end? |

Yeah memory fully inserted... If the PCIE 12v connector is not in the card starts... If it's there, it never start. Will add a few pictures tomorrow. |

Is this your PSU: http://www.bequiet.com/en/powersupply/493." rel="nofollow - http://www.bequiet.com/en/powersupply/493. if so, your PSU only has one four pin CPU power connector. Your PSU does NOT have an eight pin CPU power connector. That is fine, just be sure to put the 4 pin CPU power cable into either the right or left four openings on the mother board CPU power connector. Your PSU has one six/eight pin PCIe/video card connector. The specs for your PSU are confusing. It shows it as a single rail 12V design, but it then shows 12V1 and 12V2 rails, at 17A and 16A respectively. That means one 12V rail is good for 204W, and the other 192W. But the combined load for the 12V rails is 360W. Adding the single power rating for each 12V rail is 396W. A 400W PSU for an X99 system is really quite small. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

| Connected the P4 connector from the BQUIET SFX PSU - Now it boots properly... U can close this call... It's solved! |

I guess I got confused by the fact the MB booted without the P4/P8 cable. Physically the PCIE cable of the PSU is the same than the P8 cable. That's the second thing that confused me... The PSU went in shorting mode and did not start. The doc should have a note: DO NOT PLUG PCIE cable into that ATX slot ;-) |

You would be surprised how often we warn people about that here.  Here is a comparison shot, as you can see there are a lot of differences, unfortunately it is possible to force either into the wrong connector, the physical shape differences are not enough to prevent it  -------------

A user would need to lean on the connection/board damned hard to make that happen. Somewhere before he cracked the MB I would like to think "Common Sense' would take control of his exhaustive efforts and make them re-consider. |

" rel="nofollow - You would think but cheaper PSUs power connectors are quite soft and are very easy to force in there. I have tried it myself on budget (known brand) PSUs and it's way easier to do than it should be. Obviously I didn't try to power them up but I saw a user with this confusion and figured it shouldn't even be possible right? Wrong...... Did it require more force? Yes, but more force than a higher end better quality component that has a snug fit? Not really..... Very disturbing, especially with more and more people coming to the dark side and building their own systems. This issue needs to be addressed IMO. Some PCIe connectors have the last 2 blocks on the upper right (with the catch on top as shown in the pic) fused into one which should prevent this entirely, lets hope that catches on. -------------
