Currently: HP Pavilion 590-p0070, i7-8700. stock PSU is like a 185 Watt I believe, I supplement my power for a RX-580 8GB with a Astro 550 Watt PSU, PCIe slot is x16 version3 with 2 slots of DDR4 with 2 sticks of 2X8 GB's of Thermaltake RAM that only shows a 25% usage at most and the MB is a HP 843B with H370 chipset. After a full week of research I am at wits end seeking any suggestions, work arounds or remedies before I pull an old commercial solution and throw this bad boy out of the window! Thanks!
