CPU: AMD Ryzen 7 1700x
Mainboard: GIGABYTE GA-A320M-S2H
GPU: Sapphire Pulse Radeon RX 550 4GB
RAM: 16 GB DDR4 3200MHZ
PSU: 700 W 80 PLUS
SSD/HDD: 512GB SSD and 2 TB HDD
On the last parts i dont have any more information, forgot to wrote them down, are not any more specific in the offer and computer is at my fathers home.
Tested the pc with Display Port connected to my 1080p monitor, but after just some minute
