Tagan is perhaps not a name you
are familiar with when it comes to high-end power supplies. However if the
rest of their line-up of power supplies works as well as the SP-1000E GuardianX
1000 watt power supply we are reviewing does you will soon be not only hearing
about them, but reading a great deal more about them in your favorite forums and
magazines.
The majority of the power
supplies we have reviewed in the past have had a total of two 12-volt rails to
chose from. Some of the newer power supplies we have reviewed in the last
6-months have even gone so far as to have a total of four 12-volt rails, giving
you far more leniency as to how you hooked up your 12-volt components. The
Tagan SP-1000E goes even further by offering a total of six - 12-volt rails.
Rails 1, 2, 5 and 6 are 18 amps each, while rail 3 and 4 are 28 amps each.
So now that we have given you a run down on the beast why don't we check out the
specifications and features.

• Meets newest requirements: Intel ATX12V Rev
2.2 and EPS12V Rev 2.9.
• Six independent +12V Rails for more stability and safety.
• Support 2x8-Pin + 2x6-Pin PCI-Express or 4x6-Pin PCI-Express-connectors for
High-End Graphic cards using NVidia’s SLI or ATI’s Crossfire Technology
• Active Power Factor Correction with a high PF value of > 0.98
• Extra high efficiency more than 80% at full load which minimizes cost, energy
and heat.
