Asus X99 Deluxe II not Posting

[Doctor0707]

I have my current rig with Intel i7 5930k with gtx 980ti on a Asus X99 Deluxe II motherboard and 32gb dominator platinum My system wont post but would give off the rgb pattern light. Tried to press power button and replace the power supply but no postal code or fan moving.

I all ready have done that and still no results.

That's what everybody ALWAYS says, but has rarely actually done. If you have ACTUALLY triple checked EVERY SINGLE one of those steps, then there is something wrong with your hardware.

Either something isn't connected correctly, isn't fully plugged in or plugged in at all (EPS 4/8 pin CPU power to the motherboard is a common oversight. Not FULLY seating the graphics cards, memory or 24 pin ATX power cable to the motherboard are other common failures), or, the CPU wasn't properly installed and pins were bent on the motherboard. The only other options are a faulty power supply or other cabling not being correctly connected.

What is your PSU model? What are ALL your hardware specs.

Try benching the unit.

I have a corsair 1000th gold psu and I switched it with my testing corsair 850m

I have no idea what a Corsair 1000th is. No such thing exists.

I am having the exact issue. That it was the motherboard. I had an x99 strix gaming Asus board. Had it rma and now have the delux ii. Both same problem. Led lights on board with the "breath" effect but will not attempt to post or boot. I checked the power supply by bridging 15 pin with a black one and the fans come on, but still nothing. Everything is connected but no dice. I have a 5820k processor. Does the first generation x99 chips have problems with these gen ii boards?

For both of you, I'd try booting with only a single stick of RAM, and see if it will post. Make sure to install it in the slot designated in the motherboard manual for single stick operation.

The memory was not it. Just fixed it. Apparently the cabling from my power supply had a defect in one of my CPU specific cable for the 4 pin connector, not the 8.

So, as I originally posted, it WAS one of the things to have been checked in the initial "check these things first before posting about POST/no boot issues".

23. Make certain all cables and components including RAM and expansion cards are tight within their sockets.


I also wanted to add some suggestions that jsc often posts. This is a direct quote from him:

"Pull everything except the CPU and HSF. Boot. You should hear a series of long single beeps indicating memory problems. Silence here indicates, in probable order, a bad PSU, motherboard, or CPU - or a bad installation where something is shorting and shutting down the PSU.

To eliminate the possiblility of a bad installation where something is shorting and shutting down the PSU, you will need to pull the motherboard out of the case and reassemble the components on an insulated surface. This is called "breadboarding" - from the 1920's homebrew radio days. I always breadboard a new or recycled build. It lets me test components before I go through the trouble of installing them in a case.

If you get the long beeps, add a stick of RAM. Boot. The beep pattern should change to one long and two or three short beeps. Silence indicates that the RAM is shorting out the PSU (very rare). Long single beeps indicates that the BIOS does not recognize the presence of the RAM.

If you get the one long and two or three short beeps, test the rest of the RAM. If good, install the video card and any needed power cables and plug in the monitor. If the video card is good, the system should successfully POST (one short beep, usually) and you will see the boot screen and messages.

Note - an inadequate PSU will cause a failure here or any step later.
Note - you do not need drives or a keyboard to successfully POST (generally a single short beep).

If you successfully POST, start plugging in the rest of the components, one at a time."


If you suspect the PSU is causing your problems, below are some suggestions by jsc for troubleshooting the PSU. Proceed with caution. I will not be held responsible if you get shocked or fry components.

"The best way to check the PSU is to swap it with a known good PSU of similar capacity. Brand new, out of the box, untested does not count as a known good PSU. PSU's, like all components, can be DOA.

Next best thing is to get (or borrow) a digital multimeter and check the PSU.

Yellow wires should be 12 volts. Red wires: +5 volts, orange wires: +3.3 volts, blue wire : -12 volts, violet wire: 5 volts always on. Tolerances are +/- 5% except for the -12 volts which is +/- 10%.

The gray wire is really important. It should go from 0 to +5 volts when you turn the PSU on with the case switch. CPU needs this signal to boot.

Had you done this, you would have discovered the problem much sooner. Either way though, glad you discovered the problem and got it corrected. Good luck going forward Chorel86. Might not be a bad idea to go back through that list and double check things @Doctor.
