Hello all. I have just built a new PC. Specs are here:

PC Build
CPU: AMD Ryzen 7 2700 3.2 GHz 8-Core Processor
Motherboard: Asus ROG Strix B450-I Gaming Mini ITX AM4 Motherboard
Memory: Crucial Ballistix 32 GB (2 x 16 GB) DDR4-2666 CL16 Memory
Storage: HP EX920 1 TB M.2-2280 NVME Solid State Drive
Video Card: EVGA GeForce RTX 2070 SUPER 8 GB KO GAMING Video Card
Case: Cooler Master MasterBox NR400 (w/ODD) MicroATX Mid Tower Case
Power Supply: EVGA BQ 850 W 80+ Bronze Certified Semi-modular ATX Power Supply
Optical Drive: Pioneer BDR-2209 Blu-Ray/DVD/CD Writer
Monitor: Acer VG271 Pbmiipx 27.0" 1920x1080 144 Hz Monitor
Keyboard: Logitech K800 Wireless Slim Keyboard
Mouse: Logitech MX MASTER 2S (Black) Wireless Laser Mouse
Total: $1656.90

I am pretty sure that I should be getting over 100 FPS in Diablo 3. I am only getting about 70-80 FPS. I'm not sure if my Monitors refresh rate has anything to do with FPS but I know with my GPU it should be more than I am getting. I have checked the settings in D3 I should be able to run it with max video settings and not have a problem but I am even on the lower settings.

Can anyone here help me?
 
Solution
Please explain why you would replace the PSU? The wattage is more than enough for the GPU.
Voltage regulation and ripple. Performs 3x worse than a CXm from Corsair that I wouldn’t recommend where a CX unit that would be recommended as the lowest unit to get is probably the same price as you paid for the one you have. Wattage isn’t everything. Personally wouldn’t put that PSU in anything with a dedicated GPU. It’s a fine office PC unit though.

Not necessarily the “problem” but DDR 2666 with a Ryzen is leaving performance on the table. Cheapest PSU I’ve seen paired with a 2070 super, I’d replace that thing when you have the money.

Thanks for explaining. Any thoughts on my FPS loss?

I’d monitor your CPU speeds and GPU speeds. Are they boosting to the appropriate speeds? if not there could be reasons why like the ripple I explained not providing adequate reliable power to either the CPU, GPU or both.

RAM speed is important with Ryzen. The infinity fabric is the transfer between RAM and the CPU. It can go up to 3733Mhz. So being at 2666Mhz is a significant drop in max speed.
