The short version
MSI's MAG A850GL PCIE5 is a fully modular 850 W power supply that MSI describes as ATX 3.1 ready, with a native 16-pin cable rated at 600 W, four 6+2-pin PCIe connectors and flat cables in a compact 140 mm body. It carries 80 PLUS Gold and Cybenetics Gold efficiency ratings. It suits gaming builds that want plenty of connectors, but MSI's page states neither a warranty term nor a zero-RPM mode, so those need checking.
