Corsair RM650 (ATX 3.1)

A beginner-tier 650W supply built to the ATX 3.1 / PCIe 5.1 revision, with Gold efficiency, full modular cabling, and a 12VHPWR connector. It's a clean fit for midrange GPU builds that won't push past its wattage. Skip it for a 5070 Ti or anything higher, since those need more headroom than 650W leaves.
