MSI MAG A850GL PCIE5 850W

MSI's budget Gold default in 850W trim: fully modular, 80 Plus Gold, with native 12V-2x6 (ATX 3.1) wiring so a current-gen GPU plugs in without an adapter, plus a 10-year warranty. It's a sensible, unremarkable beginner-tier unit. Right for a mainstream gaming build that wants headroom and a clean cable run; skip it if you're chasing a silence-first PC, where premium platforms idle quieter.
