The short version
The MAG A750GLS PCIE5 is MSI's mainstream 750 W ATX 3.1 power supply, rated 80 PLUS Gold with Cybenetics and PPLP certification and cooled by a 135 mm fluid dynamic bearing fan. Its native 12V-2x6 cable is rated at 450 W, and MSI includes four 6+2-pin PCIe connectors. Tom's Hardware rated the 850 W sibling a capable mainstream unit. It suits GPUs that draw well below that cable's limit, and offers only five SATA connectors.

- 80 PLUS Gold with Cybenetics and PPLP certification

Common questions
How much GPU power can its 12V-2x6 cable handle?
MSI rates the 16-pin 12V-2x6 cable on this 750 W model at 450 W. Cards that can draw more than that need a higher-rated cable or PSU.
How long is the MAG A750GLS PCIE5?
MSI lists dimensions of 150 x 150 x 86 mm, so allow 150 mm of PSU clearance rather than the shorter 140 mm of some rivals.
