Power Supply Roundup: Eight 1000W for the Extreme Usersby Christoph Katzer on December 11, 2007 9:30 PM EST

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.
As usual, we are testing with our Chroma programmable loads to load each rail to a specific amount. This is important to get truly accurate results and not merely approximate values. We conduct tests in two different temperature environments. One is normal room temperature of 25-26°C, while the second environment goes from room temperature and increases steadily up to 50°C. Especially during the higher temperatures, we will see how good the power supplies are and how well they can perform in high-stress environments. Components inside will perform much worse at higher temperatures, but we expect any good quality PSU to deal with such test conditions without failing.
Note: If you would like to know more about our testing methodology, equipment, and environment, please read our PSU testing overview.
Before we get to the test results, let's look at the various power supplies. Some of the units appear nearly identical, which is understandable as they are manufactured by the same ODM; others take a very different approach. While appearance, design, and features are all things to look at, at the end of the day what really matters with a 1000W PSU is how well it actually performs.
