YEYIAN Raiden RGB 850W

A 850W unit with 80+ Gold efficiency certification and non-modular cabling. It uses the ATX form factor — confirm your case lists ATX support. 850W covers a 300W+ flagship GPU plus a high-end CPU with margin to spare. Skimping on the PSU is a false economy; better efficiency ratings usually mean better components and longer warranties.

Expect to pay around $2739.99, which lands it among premium options. PlanMyPC's builder flags compatibility problems automatically and tracks the latest power supply deals from multiple stores.
