MSI strengthens its cooperation with Channel Well Technology, one of the largest PSU OEMs, enriching its MPG line with a 1000W model. With the upcoming generation of GPUs and with the introduction of ATX12V v3.0 spec, it became clear that strong PSUs will be a one-way road to deal with GPU power spikes effectively. This means that we will see more high-capacity PSUs in the following months hitting the market, which will have to meet the newest ATX spec if they want to remain in the game.
For units like the MSI MPG A1000G, which is not ATX v3.0 compatible, we guess there will be revisions with all necessary changes. Please keep in mind that the new ATX spec changes will affect the PSU prices, so if you don't plan on upgrading any time soon, once the new GPUs become available, it would be more affordable to get one of the current PSUs.
The MSI MPG A1000G offers good performance, but it doesn't pose a threat to the tough competition. That said, these are the first steps of MSI into the PSU business and so far things go well, unlike its major opponent, Gigabyte. The MPG A1000G has enough power to meet the demands of the current generation GPUs and thanks to its compact dimensions, it will fit in any ATX case. If you want something with lower noise output, a solid choice is the Asus Rog Thor 1000 (2021), which is more expensive. Other good alternative options are the Corsair RM1000x (2021) and the EVGA 1000 G6.
