MSI expanded its MAG GL line of modular power supplies with two new high wattage models—the MAG A1000GL PCIE5, and the MAG A1200GL PCIE5. The company had debuted the series in June 2023, with 850 W, 750 W, and 650 W models meeting the ATX 3.0 and PCIe 5.0 spec. The company also took the opportunity to update its high-wattage connector standard from 12VHPWR on the original three models, to the new 12V-2x6 connector on the two new models. Both the 1000 W and 1200 W models come with a 600 W-capable 12V-2x6. The standards have also been updated, with MSI saying that the 1000 W and 1200 W models meeting ATX 3.1 and PCIe 5.1 standards, besides the newer connector.

On both the 1000 W and 1200 W models, you now get a 24-pin ATX, two 4+4 pin EPS, one 600 W-capable 12V-2x6, four 6+2 pin PCIe power, twelve SATA power, four 4-pin Molex, and a Berg. These PSUs boast of 80 Plus Gold switching efficiency, and feature a single +12 V rail design, active PFC, LLC full-bridge topology, DC-to-DC switching, most common electrical protections, and a 135 mm fluid dynamic bearing fan to keep cool.
