The Seasonic X900's (number two in the image) 900W output is considerable overkill unless you're building a real behemoth of a system with multiple graphics cards and multiple physical processors. Seasonic includes four PCI Express power connectors in case you want to But the real sense behind picking a supply this powerful is that components run more stably and more efficiently when they're running well within their capabilities. When we tested it at 50% load, the X900 achieved a creditable 86.2% efficiency and warmed
At maximum load, its efficiency fell to 81.6%. Naturally, though, you pay for the extra power. £109 isn't pocket money, and on a pence-per-watt calculation it would be an expensive choice even if you needed the full 900W. Its warranty is short, too, at just one year - which is particularly galling considering that most other manufacturers' power supplies come with three or even five years as standard.
