Hi there,
I recently decided to buy a PC and build it For the first time after being told it was easy and like ‘lego’ for men. After buying one for £1100 I quickly realised this wasn’t the case. I put it together and the first time I tried powering it on it ran, however, it ran for 3 mins before completely turning off and since then hasn’t ran at all. And ideas what could have happened?
Specs:
Ryzen 5 2600
MSI MPG X570 Gaming Plus
MSI GeForce RTX 2080 6GB
16GB of Corsair DDR4 RAM
500GB SSD
EGVA 550W B3 PSU

While I would have to agree with the 'lego for men' analogy, it does still require basic electronic skills.
Your issue could be almost anything, from dead on arrival hardware to installation errors.
And being honest, with a first time builder, the money is on the later.
What I refer to as a PICNIC problem. (Problem In Chair Not In Computer)

But to go through the basics and get you started:
  • check the processor is orientated the right way
  • you used thermal paste between the processor and heat sink
  • the heatsink is plugged in to the correct motherboard header pin
  • when turning on, all the LED's and fans make the right actions
  • check all cables are connected correctly
  • check all the anchor points for the motherboard to the chassis have risers
  • check the memory chips are seated correctly
because you say the PC was going for about 3 minutes, you probably have most of those sorted but it sounds like it may have overheated, so check that angle.
my concern is if it did overheat, it should have been able to be turned back on after it cooled. the fact it doesn't may indicate something has been fried.

basically, go through the motherboard manual page for page and see what stands out.

Okay. So after doing all of this already. The PC still won’t turn on. I think it might be a lack of power from the PSU only having a 550W when the graphics card needs 500W wasn’t a good idea. Think I’m going to get an 800W. Would this help?

you can test that theory by removing the graphics card and using the onboard HDMI connector.

Tried that and still wouldn’t power on. So must be something else. I’m getting a new PSU anyways as it’s 550W and the Graphics Card needs 500W. But still doesn’t answer the question as to why it won’t turn on.

Are there any signs of life from the computer or PSU at all, any lights on etc.

For the record, your GPU requires the system to be powered by a minimum of a 650W PSU and preferably a Gold efficiency rated unit from a proven brand.

MB specs here say that the MB requires the following three connections from the PSU;

1x 24-pin ATX main power connector
1x 8-pin ATX 12V power connector
1x 4-pin ATX 12V power connector

PSU specs here say that the PSU only has the following;

24 Pin ATX 1x
EPS (CPU) 1x 8pin (4+4)

This means that there is a power supply cable from the PSU to the MB missing.

Right okay. Mine is Bronze 80+ so not good enough. And there is a CPU PWR2 that isn’t plugged in. Is there a recommended PSU?

Can you also answer the question that was asked, there is no point in replacing anything until we have determined what is going on, the present PSU should at least power up with the RTX 2080 not in the board.

Can I ask that you do not quote every reply, it really does not help any and just makes for unnecessary reading, thanks.

Okay, I have tried without the GPU and the motherboard gets power but the pc doesn’t start. The Flash BIOS button flashes 3 times and that’s all I get.
Sorry for the issues

Quick test for you to do, completely disconnect the PSU from the MB then follow the steps in the video here to see if the PSU activates, its a Corsair video but the principle is the same as with your PSU, there is also no need to connect a chassis fan.

No worries, a lot of folk quote every reply and we have to read them because they sometimes insert info into the quoted reply.

Nevermind, I found which cable was which using a picture on google. Nothing seemed to work but I could hear the PSU was on so not sure what was happening. Then PSU fan wasn’t spinning but it was making a electric sound

while the PSU may not be the best fit, the PC did work fine for about 3 minutes before turning off.
I think we could be looking at a DOA (Dead on Arrival) issue - probably the PSU but who can say.

I'd be taking it back for a warranty repair.

Check the back of the PSU, if the eco mode switch is in the off position turn it to on to see if the fan spins when you attempt to jump start the PSU.
