Are you an experienced builder? Did you bench-test the hardware before putting it in the case? Please list all your components, especially the power supply make/model & wattage. Also, what type of CPU cooler & how was the thermal paste applied? Ryzen CPUs use the vertical line method.

This is my second build ever. No I didnt I just knew amd cpu would go with the motherboard. Power supply - Corsair TX550M 80 PLUS GOLD, 550 watt. CPU cooler came with the ryzen 5 1500x

✔ Best Answer
The bench-test is an important step. It's a way of confirming that all the hardware works before it goes in the case. Now you have no idea if you have a hardware problem or an assembly problem. Are you sure the CPU cooler was installed correctly?

You didn't list the components like I asked, but if you have more than one stick of RAM installed, remove all except one. Disconnect the SSD or HDD, DVD drive, & remove all cards except graphics. You realize you need a graphics card, right? The majority of AM4 boards have graphics ports (VGA, HDMI) but they won't work unless an A-series APU is installed. You should also disconnect all external devices except a monitor & keyboard (PS/2 style preferred). And if your board doesn't have a built-in speaker, a chassis speaker should be connected so you can hear any beep codes. Once you've done all that, try to boot & see if you can access the BIOS using the keyboard.

BTW, the PSU is a good one should be OK.

Ok but how do i bench test if no display works. I used just enough paste between the cpu and the cpu cooler. made sure by doing it twice.

Motherboard- Gigabyte | GA-AX370-gaming K5
GPU- EVGA GTX 1050
Powersupply- Corsair TX550M R
RAM- G.SKILL Ripjaws V Series 8GB (2 x 4GB) 288-Pin DDR4 SDRAM
Case- Phanteks Eclipse Series

I hear no beeping probably because my case doesnt have . where can i get one of those and wahts there name?

You should start by eliminating all the unneeded hardware as I listed above. You don't need a hard drive, DVD drive, mouse, 4 sticks of RAM, etc to bench-test. Start with minimum hardware & then work your way up.

You should be able to pick up a piezo speaker for about a buck: https://images-na.ssl-images-amazon... or maybe you can pull a PC speaker out of an old case: https://upload.wikimedia.org/wikipe...

Correct thermal paste application is critical. I'm surprised the AMD stock cooler didn't come with a thermal pad pre-applied. All Ryzen CPUs use the vertical line method. If you applied the paste differently, that may be your problem. Here's a picture of a Ryzen 5 with the heat spreader removed; it will show you why the line is important plus it must go in the proper direction: http://img.danawa.com/images/descFi...
