Built by Enthusiasts.
Switched from a 750W unit for my RTX 4070 Ti build. The native 12V-2x6 connector eliminated adapter clutter entirely, and voltages stay rock-solid under full load.
I've deployed over thirty of these in client workstations. The full modularity saves hours per build, and MSI's ATX 3.1 implementation gives me confidence for high-end GPU upgrades down the line.
