Just got done putting together a new computer and it won't boot. No post codes, no beeps, nothing. The G skills rgb lights up when osu is on, and my Kraken blinks on for about half a second when I press the power. When I power on the psu the motherboard flashes all it's lights. Fans haven't moved at all and I get nothing on either monitor at any point.

I've tried using a different gpu and cpu cable (8pin).
Tried different slots on my psu.
Reseated everything, literally everything.
Tried with and without my gpu.
With 1 monitor and 2, on and off the gpu.
Changed ram to different slots and tried each individually.
Read the entire motherboard guide.
Verified everything was installed/screwed in properly.

I5 8600k
Gigabyte gaming 5 Auros z370 mobo
16g g skill rgb
500g evo 960
NZXT Kraken x62
Vega 56
Xfx 1050w fully modular
S340 elite


Edit: If I hold the power button down for an extended period of time I get the same flash from my Kraken and a quick red flash on my mobo where I'd hope for a code.

Did you test your GPU in your other computer to see if it works? That'll either confirm or rule out a bad GPU. This is why I always test boot in the minimum configuration on my motherboard box before I put it in the case. When I built mine in March I put the MOBO on top of its box, added the CPU, Cooler, RAM, GPU(no integrated graphics on Ryzen), and PSU to test the components. It helps avoid problems like this where you're constantly in the case pulling things in and out not to mention eliminates the possibility of a short circuit.

Ok, That info would have been helpful. Step one strip down to the bare minimum of components again. Reset the BIOS then use one stick of RAM and try each RAM slot 1 at a time and see what happens. If it continues to do the same use the second stick of RAM and do the same with it. PC constantly resetting indicates a RAM issue generally. This is preferably done with a CPU cooler attached. A case fan isn't ideal for what we're doing. So try it with the Kraken but only plug in the pump don't plug in the USB connection to the mobo and try that.

Maybe a stupid question, but how do I reset the bios? Will reference the manual when I get home incase it has that info.

Also, when you say strip, is just unplugging everything from the mobo acceptable? Or the psu as well?

Should have clarified. Yes reference your motherboard manual for how to reset your BIOS/CMOS. When I say strip unplugging everything is fine just as long as the only things connected to the motherboard are the items I mentioned. No graphics cards, no front panel connections, no hard drive, basically you want the only things necessary for a PC to boot into BIOS. It's a troubleshooting tactic to narrow down what the issue could be. If it boots in the minimum configuration you add 1 component at a time until it doesn't boot and generally that part is the one causing the issue. Just noticed the last part of your question, Yes you need the PSU plugged in but only the 24 pin motherboard power connection and the 4/8 pin CPU power connection.

I made some progress! Though I don't know what to do with it...
The part of the "power cable" that plugs into the top of the Kraken on the CPU (one that looks like a sata) seems to be causing issues. I unplugged it just for giggles, and the computer booted. Got my aorus splash on the monitor.

Edit: So I was able to install Windows, but my pump and pump fans are not running at all...

There were 2 separate cables that came out of it, I had unplugged the USB like you recommended, didn't realize you meant the other one as well, which just doesn't plug into the motherboard at all.
It won't pump without the sync cable I'm assuming, if that is what that one is?
I can boot and get into windows with the usb cable plugged into the motherboard, but it won't pump.

There should be 2 cables. 1 that is a micro usb that plugs into your USB2.0 headers on the motherboard which shouldn't be needed for boot and should stay unplugged. The other which plugs into the CPU fan header and splits off into a PWM fan connection splitter that one should be plugged in. If you had disconnected that from the motherboard what was connected in it's place? A case fan? Hence the confusion because a PC won't boot if nothings connected to the CPU fan header. If the power cable isn't plugged into the CPU fan header from the Kraken that'll also explain why the pump isn't running. I suggested unplugging the USB cable a while ago mainly because it's probably not compatible until you get all of your BIOS updates done and all of the drivers installed. Should be able to run just fine without the USB/Sata looking cable for now.

I tried every combination of cables being plugged and unplugged, leaving the usb unplugged for most. Tried changing fan config in bios. The computer just would not boot with the power cable.for the Kraken plugged into the Kraken (it is plugged into power on the psu via the sata and the cpu_fan is connected, these are all part of the same cable).

I plugged the cooler into the hpwr_fan with all the other fans in the mobo and nothing in cpu_fan and it booted with everything (everything everything) plugged in, but my pump wouldn't run. Tried rearranging the fans to see if I could make the pump run after installing cam and updating the drivers, and then it stopped booting again.

Think I'm just going to call it quits on this one, was really hoping i could get it working. Thanks for the help though, I appreciate it.

In the end NZXT may be right and I've just had the bad luck to get two bad Krakens in a row.
I honestly think it's a power issue though, but I really don't know how I can force it more juice.

I have a corsair h60 that works fine for now til I decide what I want to do... Maybe I'll try a thermaltake since I find the evga ones kinda ugly.

Yeah seems like your system isn't playing well with the Kraken then. Just in the reviews I've seen and product pages it seems way too complicated for what it is. You very well could have 2 bad ones in a row. Your PSU is brand new like you said and has plenty of juice to power your system so I honestly don't think it's that. Did the H60 work when you plugged that in? H60 is a good cooler if you don't plan to over clock. I'm using one currently with my Ryzen 1700x until I can buy a new case with room for a 240/280mm radiator. Once booted is everything up and running normally? PC troubleshooting is hell some times so I just want to make sure It's running normally and there's no issues other than a wonky cooler. On another note you could have saved a few bucks on that PSU. A 1000W PSU is overkill for your system. 550 to 650W would be perfect unless you plan on running SLI on your GPU's in the future in that case you'll need all of that power.

Well, new issue now. I switched to the corsair h60 and it booted fine, without the gpu. Was able to function normal, temps were good, fans were running.

Then I added my vega 56 and now it won't boot again... I unplug the Vega, it boots fine, plug it back in, same issue as with the Kraken...

Side note, the 1050w psu was a replacement XFX sent me when my 750w died last year. Ended up buying a replacement because I couldn't wait for the rma, and kept the 1050 in the closet til now.

Man you're just catching hell with this aren't you. Ok leave the GPU out for now and Update your BIOS, chipset, and MOBO drivers to the latest off of the Gigabyte website. The latest BIOS update is from 7 days ago. Once that's done see if it'll run with the GPU in. I'm a little unsure as to why it won't boot with the GPU in. It should boot but sometimes the BIOS has to be set to a discrete GPU in order to use it but it shouldn't hold it up from booting. I'm not sure if you can check voltages in your BIOS but it'll also be worth checking your 5 and 12 volt rails to make sure they're still in line as well. The other thing you can try is using another PCI slot to rule that out as being bad. Given it seems like you're having power issues I'd also pull your motherboard out of the case and make sure there's not an out of place screw or stand off that could be causing shorts. You're getting some very weird issues.

I think you've already RMA'd you're board but I'd check the CPU pins once more for damage and the CPU it self to make sure there's no damage. Everything points to electrical like something on the CPU socket is damaged or there's a short between the board and your case.

Already updated Bios, chipset, and all mobo drivers to most recent last night, was one of the first things I did when I booted on integrated.
Looked through my Bios, but didn't see anything relevant to the GPU, so I might scan over the manual just to be sure.
I tried both rails on my gpu, and separate power cords.

I'll have to pull the cpu and motherboard out and look at them again, because I've done pretty much everything else... It's crazy the amount of trouble I've had with this build, maybe it just wasn't meant to be... I'm on the edge of just returning everything and sticking with my old comp, it still runs fine...
