There are so many 1000W PSU on the market, so which one do you think is best?
MSI MPG A1000G PCIE 5 & ATX 3.0 Gaming Power Supply: https://www.amazon.com/MSI-A1000G-Gaming-Power-Supply/dp/B0B434DB7Y/?tag=6890-20
Honestly, any of the top brands (Seasonic, Corsair, EVGA) will serve you well at this tier. Just make sure to get something with at least Gold efficiency and a good warranty. The differences between the best units are pretty minimal in real-world usage.
The Corsair RM1000e PSU leads in efficiency and quiet operation. The MSI MPG A1000G PCIE5 is another strong contender with positive user feedback. Both power supplies are reliable choices for high-performance systems.
