The Ultra X3 600W and 1,000W units overall are fantastic bits of kit - they look as good as you can get and have an awesome set of cables to complement the shiny gunmetal box. If you need a 1,000W model then the Tagan or Enermax might still be slightly better options in terms of absolute performance though. The Ultra X3 600W is an excellent choice for those wanting a mainstream unit and although it may cost a bit more, it's certainly a worthwhile investment. Many will still love the highly recommended Corsair HX620, and quite rightly so, but the 600W X3 should be considered quite a serious contender to it because it does just about everything right.
