6.6/10verdict: good, not the best

This is a 750W ATX 3.1 power supply for a single-GPU desktop where low noise and a long warranty matter more than cable tidiness. It suits builders who want a native 12V-2x6 connector and Gold efficiency and are happy with fixed cabling. It is a poor fit for multi-GPU builds or cases that need a minimal cable count.

6.3/10verdict: good, not the best

The MSI MAG A850GL PCIE5 suits builders putting together a modern gaming PC who want a fully modular 850W Gold supply with a native 16-pin cable. It fits those who value cable management, quiet running under load and PCIe 5 support. It is less suited to always-on machines that idle at very low loads.
