Today we take a look at another new power supply in the MSI catalogue – the MPG A1000GS. This PCIE5 ATX v3.1 supply is fully modular, and is 80 Plus and Cybenetics gold certified. Is this a unit you want to be shortlisting for a new build in 2025? Let's find out.

While the last flagship MSI power supply I looked at cost a staggering £600 (MEG Ai1600T – review HERE), the MPG A1000GS I am reviewing today has an more palatable MSRP of £184.99. Checking pricing online as we go to publication this indeed appears to be the case (HERE). MSI are including two native 12V 2×6 connectors to support the new range of RTX 50 series graphics cards (although one is surely enough for a 1000W PSU). This power supply has a power excursion rating of 235% and is PCIe 5.1/ATX 3.1 ready.

The OEM partner of choice for this power supply is CWT based on the CTE platform.

This power supply falls into the mid tier of a ‘triangle rating system' inside documentation that MSI sent us. I think this is worth a little clarification today as I had so much to discuss regarding the Ai1600T in the previous review, I did not dwell on this at all.

So, for clarity, the ‘MEG' range is ‘Enthusiast Gaming' sector in the high end, with the aforementioned £600 Ai1600T filling that slot. The supply we are testing today falls into the MPG ‘Performance Gaming' sector and the lower end 1000w/850w/750w/650w units fill the MAG ‘Arsenal Gaming' sector.
