MSI MPG A1000GS PCIe 5 PSU Review
Conclusion
A solid yet baffling power supply
I’ll be honest. The MSI MAG A1000GS PCIE5 confuses me. While I like its dual 16-pin (12V-2×6) gimmick, its lack of multiple 8-pin (6+2-pin) PCIe power connectors has baffled me. For a modern 1000W power supply, I expect to see at least three of these connectors, not one.
Yes, this PSU is designed for modern Nvidia GPUs. After all, MSI doesn’t make any current-generation AMD GPUs. Even so, losing the option to power GPUs with multiple 8-pin inputs is a big deal. Honestly, this PSU makes me wonder if 16-pin to 8-pin adapters exist, where I can power three 8-pin PCIe power connectors using a single 12V-2×6 connector. If they do, this power supply would have benefitted from having one of these adapter bundled.
Aside from this obvious issue, there is nothing that we can say that’s bad about MSI’s MPG A1000GS PCIE5 power supply. Its voltage ripple results are reasonable, its power efficiency levels are as advertised, and it is virtually silent. If you don’t care about having multiple 6+2-pin connectors, this PSU is an excellent option.
As someone who loves building PCs, I cannot help but think of situations where I might want more PCIe 6+2 power connections. Perhaps my preferred GPU isn’t in stock (a common problem these days), and I need to use this PSU with my old GPU? If that GPU uses two (or more) 6+2-pin PCIe connectors, I’m out of luck.
When new GPUs can be released with up to three 8-pin PCIe power connectors, it is crazy to see a 1000W PSU lacking them. With this PSU using two 12V-2×6 connectors, there may be technical reasons why more 8-pin connectors are unsupported. Even so, the lack of multiple 8-pin connectors makes this PSU hard to recommend. As such, it won’t be receiving an award from us.
