Power Supply Roundup: Eight 1000W for the Extreme Users
 

We recently published a major roundup of several high-end power supplies. As stated previously, such power supplies are already more than what most people will need, but for those looking to push extreme overclocking to new levels you might still need more power. We have eight 1000W power supplies we're looking at today the aim to provide just that. It's no surprise that power supplies in this range typically use high quality components, and the prices are also quite high. We have units from well-known companies as well as companies that are less familiar to our US readers.
