    Default AsRock z97 Extreme 9 wont power on

    As the title says, I am having problems with my computer. Last night while playing a game the computer immediately shut down like it had lost power. This was the second time it had happened, the first time required disconnecting the power from the power supply waiting a few seconds, then by using the power button on the mobo (not the chassis power button) it turned back on.

    Last nights situation was a little rougher, I removed everything from the mobo except the processor, reconnected everything, that did nothing. After resetting the cmos it finally turned back on. Currently the computer has been shut down for 2 hours, i have tried resetting the cmos again to no avail. The lights on the lan flash like the lan is connected, the usb ports have power, the light on my AIO water cooler has power, but the mobo will not power on. Any thoughts?

    Also, this is my second psu. I originally had a cooler master silent pro 1000, but at random times it would sound like it was a plane trying to take off. I was thinking that couldn't be good, so I returned it, and got a different psu. The corsair ax 850, it is a refurbished model... Could the first power supply have caused an issue, or was the motherboard having issues all along and the first psu was able to absorb it?

    I just pressed the power button on the mobo, and presto! it turned on. I hadn't done anything to it, and the power was connected to it this whole time. Anyone have any ideas as to why it wouldn't power on, but now it will after doing nothing to it?

    Carefully inspect the 8-pin EPS_12V psu cable to ensure that both ends of the cable are fully seated.
    Also look closely at the connectors to see if there are signs of damage.

    The Corsair AX850 is a better power supply and hopefully there aren't any problems with it being refurbished.

    Can you test your system with a 500 - 600 (or higher) watt power supply to see if it makes any difference?

    If there is an electrical problem with your system, higher quality power supplies will not power up your system or the power supply's protection circuits should shut down the system. Make sure that none of your hardware is running hotter than normal.

    I just saw your latest post and sounds like your power supply might be overheating and that it took a while for the psu to cool down before it could restart.

    I was just gaming for 20ish minutes, and none of the temps got above 53 degrees (i know its not a long sample size, but i have to run so I will test for longer tomorrow when I'm home). I'm using HWMonitor to view all the temps.

    If the power supply was overheating, why would the mobo still have power (usb ports were charging my phone, the watercooler had its light on, and the lan card was connected to the router)?

    There are no signs of damage on the 8 pin cpu power cables, although they are 2 groups of 4 pins, not a single 8 pin. And I have both 8 pin cpu power connections attached. Do i need to have both 8 pin power connections attached if I am not overclocking?

    Thanks for the reply ProfJim

    You're welcome, glad to help out.

    Using the two 4-pin (ATX_12V) connectors is fine and is identical to using a single 8-pin EPS12V connector.

    It sounds like the power supply is able to provide low power to usb ports when the power supply can't or won't power the rest of your system.

    See if your system will run normally with another, good quality power supply.
    If it's a lower power psu you might need avoid running with high electrical loads, especially if your cpu and video card are highly overclocked.

    A low cost (~$15 - $20) psu tester won't help much as they only measure voltage, not how many watts your system can provide.
    You would need to use a Kill-A-Watt power meter or a higher end UPS unit to measure how much total electrical power your power supply is using.

    I expect that your AX850 is cool running and that it should only be slightly warm when your system is running.

    Regarding the power button on the board working instead of the power button on the PC case, that could be a problem somewhere in the case's power button to mother board header connection system. Such as, a bad connection at the mother board header, pinched wire from the case power switch, case power switch starting to fail, etc. Or it could have simply been a coincidence, if the case power switch now works consistently.

    If the LAN LEDs were blinking and you had power to the USB ports, the board was receiving power and was on in the standard S5 power state, but the main 12V, etc. rails were not active, which is normal in the S5 state. The signal that causes the PSU to become fully active and then the PC to operate is sent to the PSU in only one way, whether by the PC case power switch, or the switch on the board.

    What PC case are you using? I would check the entire power switch system in the case, and if the case has a power connector for its own use (most do) then check that connection. Using an electrically operated power switch in a PC is highly unnecessary, but anything is possible. Of course the most obvious point of failure is the connection to the board.

    You certainly do not need to have both eight pin CPU power cables connected to the board if you are not over clocking. Frankly, you don't need both of those cables connected if you are over clocking. The vast majority of mother boards used to over clock have one eight pin CPU power connector.

    For example, the new ASRock X99 Extreme 11 board has one eight pin CPU power connector. The X99 OC Formula has one eight pin and one four pin CPU power connectors. ASRock boards from their "Overclocking" series will normally have more than one eight pin CPU power connector. That type of board is capable of being used with extreme CPU cooling techniques (liquid nitrogen) for CPU benchmark records at abnormal CPU core voltages and power consumption.

    The use of two eight pin CPU power connectors on that board is not obvious, but may be related to its 4-way SLI/Crossfire support. Given your current hardware and configuration, you don't need both of those cables connected.

    Thanks for the responses parsec, and profjim. This morning it happened again, under the same exact circumstance. The game in question is Path of Exile (and it only happens when playing this game), when i use the skill Discharge, my frame rate spikes from ~140 to 1. I had been using this skill several times, but I like to use it right when a bunch of guys spawn, and when i pressed the button on the keyboard to activate Discharge it was like I pressed the switch on the power supply.

    Someone on the PoE forums had stated that PoE does have a fair amount of cpu processing, and that the power boost from the intel chips sometimes has issues with PoE on newer intel chips.

    Is it possible that the cpu load spikes up to the point the power boost kicks in, and that extra instantaneous load on the psu is causing the power rails in the psu to trip (like a surge protection)?

    I am going to unplug one of the 4 pins going to the cpu, and I would also like to disable the power boost feature but I'm not sure where the setting is for that, can anyone help with that?

    Also about the power button, I will always press the case power button first, before the mobo power button, I haven't been doing that in the past (only when the computer is in its current state, otherwise the power button works normally), so its quite possible that the case power button is just fine, I was just impatient and thought that button was different for some reason.

    Going from past experience I won't be able to turn the computer on for a few hours, and being that it is sunday I'm going to watch some football, so I won't be back until later in the day, but any help is very much appreciated.

    Default Re: AsRock z97 Extreme 9 wont power on

    Okay So I removed one of the 8 pin cpu power connections. In the UFEI I disabled turbo boost, and in windows I changed min power state to 25% and max power state to 90%. I gamed for a while no problems (i also turned v-sync off in the game). The cpu's frequency never went above 3.5 ghz. I exited the game, changed the max power state back to 100% started the game back up, the first time I used Discharge (about 20 - 30 sec into playing) the computer powered off immediately.

    Any ideas?

    Is this a new(er) build? Or one that's been running a-ok for some time now?
    #1 - Please, when seeking help, enter the make and model of ALL parts that your system is comprised of in your Signature, or at least the model #'s in your System Specs, then "Save' it.
