Much like the Corsair RM1000e we just looked at, the MSI MAG A1000G similarly outputs around 1000W at 80 Plus Gold Efficiency. However, MSI is proving why they’re one of the hottest gaming brands around, as this PSU is both more compact and more stylish than pretty much anything else in its respective class. Aesthetics are a big part of PC building these days, as is performance, but thankfully the MSI MAG A1000G has plenty of both!
Efficiency is excellent on this PSU, and while Titanium and Platinum rated units are better, they also cost a lot more money, so 80 Plus Gold strikes a good balance for gamers, especially when the MAG hits over 92.6% efficiency at around 600-800W load, which is an ideal zone for a high-end gaming PC.
PC gamers often have to deal with spikes in power too, which requires that a power supply can handle the big increases in power as well as the transitions from one power state to another and the MSI MAG excels at both, with a peak output of 1265 Watts, around 27% over the rated 1000W!
While also dealing with rapid changes in voltage perfectly thanks to some of the best transients we’ve tested so far, such as this 0% to 100% load on the 5v rail demonstrated below.
Their PSU is based around a CWT design, but MSI modified it to allow for a larger 135mm fan and hybrid cooling mode, making it much cooler and quieter too, and capable of being completely silent under 40% load.
With the latest ATX 3.0 and PCIe Gen 5 standards, allowing for the latest 12VHPWR connector natively as well as a secondary one that runs from the PCIe slots, a good range of more traditional PCIe connectors and peripheral connectors, it’s more than capable of keeping up with both current and future PC demands.
