Mining rig not turning on

[Erick3150]

Hello,

I recently got all the part for my mining rig but I got a big problem. It just does not turn on. I installed the CPU, RAM, etc. I try to turn it on without any GPUs and it just turns on for a fraction of a second. I thought it was the PSU did not have enough power, but it doest even work without the GPUs. It ONLY works when I unplug the power to the CPU. Here is a parts list

-ASRock H110 Pro BTC+

-Celeron G490 LGA1151

-2x DDR4 2666

-Varago PSU 600W (pic in the folder)

-GPUs (not connected)

I got two of these Varago PSU in case I needed more power, but I cant even turn on the mobo without the GPUs. I even tried connecting both PSUs to the mobo. One to the main power and the processor, and the other PSU to the extra power ports. I also tried to connect one PSU to the main mobo power and the other PSU to the CPU power and same result. Still does the same thing. I tried to look for an answer online but could not find anything. I tried to remove the RAM and put it in again, nothing. Removed the CPU and fan and installed it again, nothing. I am not sure what the problem is. All the components are new. Here is a video showing the problem and a pic of the PSU. https://drive.google.com/drive/folders/1D7BsnPlTva9fi6LkuZJ7IMiP_ZyosDaZ?usp=sharing

DO NOT use 2 separate power supplies to connect to the motherboard directly.

Only connect 1 PSU to the Motherboard mixing them is not advised as per Asrock.

Would it be a problem even if its the same PSU? Because I was going to use that other PSU to power on some of the GPUs. Besides that, it still doesn't turn on. Even if I just use one PSU.

One problem at a time mate, one problem at a time, fix the motherboard to power on first before worrying about using two power supplies on the motherboard, if the motherboard is up and running then we can talk about how to use two power supplies

Great advice. I took out the mobo and disconnected everything from it. Just left the basic components on with one PSU (which i have 2 of the same ones). Tried it again and didn't work. Here is a video of it,

Would it be because the PSUs are "uncertified"? Because they should have enough power to turn on a PC with 1 RAM stick and a Celeron CPU.

sounds to me like you have a short, if something is not seated properly, reseat ram, cpu, what is the motherboard sitting on?

I doubts it psu as there is very little power needed without gpus.  Sounds like it may be a dead board.  

Did you blank CMOS setting?

Besure to unplugpower cord before doing this.  

I think ive got your answer....G4900 is not supported by that board...

see here
https://www.asrock.com/support/cpu.asp?s=1151&u=1062

You can see here a Pentium G3560 is supported:

https://www.asrock.com/support/cpu.asp?s=1151&u=945

Just because it is celeron or pentium LGA1151 gotta check if it says 300 support only.  Change the cpu and you should be good to go.

Tried that and it did not work. Tried it twice and got the same result. I also checked if I had any shorts and it doesn't seem to have any. I have the mobo sitting ontop of the anti static bag in came with. The mobo supports Gen 6 and 7 of intel. I have the Celeron G4930 LGA1151. It should be compatible right?

Sorry your original post shows only G490 for cpu.  

No its not on the list from ASROCK site...meaning its not supported.

http://www.asrock.com/support/cpu.asp?s=1151&u=1147

It requires a 300 series chipset...This is 110 chipset.

[Erick3150]

Thank you. I think I found the problem then.

[miner29]

Looks like G3930 should work...cheapest $112

or an i3-7100 $133....


found using pcpartpicker.com

will work

[Erick3150]

Great, thank you. On the specs of the mobo it says it supports up to 2400 RAM. I got 2666 RAM. Would it still work?

[miner29]

Generally yes....the ram is just capable of faster operation.  The general rule is it can be faster than needed but wont run faster than what is required.
