Hi, so I have just finished building my second PC (with lots of experience rewiring my current one) however the computer won't respond at all when I turn it on.

The PC;
MOBO - MSI B350 Mate
CPU - AMD Ryzen 5 1600
GPU - Gigabyte geforce GTX 1050
PSU - cougar GX-F 550 (550 W)
RAM - TeamGroup 2x4 3200mhz
Case - Corsair carbide 275R

There are currently no SSD or HDD plugged in as they will be taken from another PC.

I have checked all the cables several times to ensure i haven't made a mistake. The case is definitely plugged into the right pins on the MOBO and yes, the power supply and wall were also turned on. I have checked the power was connected correctly to both the MOBO and CPU and the connections are connected without any gaps.

what components should I check and how should I check them. I have a Ammeter, voltmeter tool thing which I know how to use. however, don't know how I check components with it.

Final thing, I don't believe the PSU is new or it has already been opened the reason for thinking this is the warranty sticker has been ripped and a small piece of it is missing. I noticed this after removing it from the case the to inspect the PSU assuming it was the problem.

I have removed the PSU from the system and unplugged the motherboard for further inspection.

Thanks

Jump start the psu to check it powers up (google 'jump start psu').

Try running it all out of the case. The motherboard box makes a good platform for this.

I'd always check it all works before installing it into the case.

Edit: Any chance it needs a bios update to support the cpu you're using?
 
Sounds like the PSU to me, especially given that the warranty sticker is broken. Connect a fan or two then short out any green and black wire on the 24pin ATX connector
 

I have followed both of your steps and some tests myself here are my results.

I have checked the power supply to work by using a jumper which I have concluded is working (at least partly).
Now when I power on the PC all of the red debug light flash and the PC turns itself off almost instantly.

I have checked the ram by removing one of the 2x4 so the PC has only 1 ram stick inserted.

I have removed the GPU and now when i power the PC i get a different response, the debug lights now flash however the PC doesnt turn off instantly, the bottom 3 lights indicating the RAM, Boot device and GPU stay lit.

I plugged in the case fans but they wont start when I power the PC.
The PSU fan will not start* when plugged into the motherboard however will start when I jump start it.
To conclude the previous two points, NONE of the fans start at all, however *PSU fans move but don't finish one full rotation.

When I press and hold the power button the PC does not turn off, i must use the power switch to turn off the PC.

I have reset the CMOS using the head of a screwdriver and shorting the battery, I have had no positive response or effect from the motherboard.

The onboard GPU doesn't take the place of the inserted GPU when not plugged in. Asif onboard doesn't work.
 
After i re-read the Guide i think you might be right about the onboard graphics, i believe the manual may be referring to onboard graphics if you have it on the PCU.
With the bios issue, I doubt it as my current PC also has the Ryzen 5 1600 with the MSI B350 Tomahawk, whereas the PC im building has a MSI B350 PC Mate (same CPU)

[edit] I wouldn't have thought a bias update would effect the start up either.
 
What if the first board happened to come with and recent enough bios and this one didn't? That's assuming it is one of the boards where the bios could be an issue.

Have you contacted the supplier to check that there couldn't be a bios related incompatibility?

This has become a standard bit of advice, I do it too, however... Be aware when inserting things like tight RAM modules, GPUs or installing coolers that the motherboard box will allow the motherboard to flex badly. I have seen YouTube videos where some of the main channels show the motherboard box as the best place to build a system, but then badly bend the board inserting the memory. All it takes is for you to crack a single track and you will have endless amounts of intermittent issues.
