UPDATE: Technician replaced the board with asrock b450 gaming 4 and all is working well again. He tested a 2nd gen ryzen chip with my asrock b450 Pro 4 motherboard and it didn't work. Seems that board is dead so will have to RMA it.

Alright, so he brought another PSU and tested with the computer. It didn't come on @ all. So I advised he remove the motherboard from the case, and try it (breadcumbing) and he did so. Still did not come on. He removed both ram sticks and still no power. CPU fan doesn't come on. My conclusion is that this new board is bad after just 2 weeks of usage. However, he will be returning today with another motherboard and a ryzen second generation processor. We also can't rule out the new processor I bought isn't faulty either. I will update again when I have new information.

Good luck, tell the technician to make sure it is a newer model PSU, that ZS series unit is from 2010/11, it may not meet the specs for current hardware properly.

Voltage from the wall outlet tested with a automatic voltage stabiliser shows 220~240v. That's the range we use in this part of Africa. Jiwlow voltages detected. The computer technician will be bringing another PSU tomorrow. I will update you on how things pan out when he comes. I appreciate all the help you are giving m and I hope to resolve this.

As I said, some PSUs will have low voltage protections that will prevent them
from coming on if power is low and there is a load attached to them. I have had power supplies come on with the paperclip trick yet fail to come on when connected to a system, they were dead. Your options are pretty simple: Test your voltage from the wall (or have an electrician do it to be safe). Try a different, new PSU, your current one could have an issue. Your symptoms do not align with a faulty motherboard, issues like this are almost always power related, either with the supply from the wall or from the PSU itself. Stay calm and don't panic, we (the forum community) will help you get the issue resolved Let us know the results of the suggestions I made and good luck |

I took the risk of plugging the system direct to a power outlet, and still didn't come on. I tried the paper clip test on the PSU after disconnecting it entirely from the mobo and it turned on. I now reconnected it back, and removed both ram sticks, still didn't come on. I removed the computer case wires for power button and used a screwdriver to jump start the mobo, still didn't come on. This is a brand new asrock b450 pro4 motherboard. I don't know what else to do?

Check your power in your house, if you are running under voltage that will
cause the issue you are experiencing. A lot of electronics will continue to run on low voltage (including PCs) but a UPS is designed to keep power at rated spec. This means that the UPS will draw power from it's battery to supplement low power. Just like when a UPS turns off after a power outage when the battery is drained it will do the same if the battery is drained and you have low power. It may allow low wattage devices to work but when it senses a load beyond what it is able to provide it will not send power to that device. In all likelihood your PC will power on if you connect it without the UPS unless your PSU specifically has a low power protection. Most quality PSUs are switching models that are able to handle voltage from 110v (US standard) to 260v and quite a bit in between. I wouldn't recommend using your system without a UPS if you have bad power but connecting it just to test for a brief period should be fine. If your power is indeed low then you will need to contact your power company and report the issue. |

He brought the system back yesterday and tested with his own UPS and it came on. He tested with my own UPS and it came on. So to err on the side of precaution, I took his UPS to test with my computer. Worked fine for just a day and now this morning, it won't come on. Opened it up and rechecked all connections, nothing. My mouse and speaker lights come on but no power to the case fans, CPU fans or gpu. What else can I do? Is this a motherboard issue or a psu issue?
