To be honest, my buddy set up all the parts i have then i had bestbuy install it. The 850w that i got is more than enough for my set up, per him i deff trust him. He just got himself a similar set up. Ive only had mine a week or so and i absolutely love it. Hope this helps. When it comes it pc stuff, im not that knowlegable. Hence why i needed help.

Sorry, there was a problem. Please try again later.Your 850W PSU is sufficient at stock settings, but the XFX MERC 310 RX 7900 XTX requires ~350W–400W, and with a Ryzen 9 5900X (~105W–150W) and the rest of your system (~100–150W), total power draw can reach 700–750W under load. Avoid using a pigtail—each 8-pin connector should have its own dedicated PCIe cable to prevent overheating and voltage drops. Since your RM850e only includes two PCIe cables, get a third PCIe cable from Corsair for safe operation. If overclocking, a 1000W PSU is recommended.
