Seasonic X900 SS-900HP 900w PSU

Conclusion

Conclusion

To put it simply, the Seasonic X900 is a wolf in sheep's clothing. Managing to keep the size of the X900 to not much bigger than your average ATX PSU, Seasonic have ensured that the X900 will work in a wide range of PC enclosures from spacious towers down to compact lanboxes.

This combined with the extremely impressive efficiency figures of almost 85% and minimal voltage fluctuation across each of the X900's rails shows Seasonic's dedication to not only manufacturing power supply's with excellent performance, but consideration for the environment and of course your energy bills too!

Currently priced at just under £130 over at Aqua-PC's and Scan, the X900 is at an amazingly good price point that can currently only be matched by lower wattage units from other manufacturers.

The Good
• Very good voltage stability on all rails.
• Extremely high efficiency of almost 85% reported by our equipment.
• Dimensions not much larger than a standard ATX PSU.
• Very competitive pricing for a 900w unit.
• Silent up to and beyond 50% load.
• 4x PCI-E cables and support for the latest 8-Pin PCI-E standard.

The Mediocre
• 80mm fan gets a tad noisy at 100% load.

The Bad
• Nothing to report.


In recognition of these excellent qualities I need to congratulate Seasonic for managing to obtain Overclock3D's "Best In Class" award. This award signifies that the Seasonic X900 900w PSU is considered by Overclock3D to be the best all-round power supply in the 900w and above classification for the month of September, 2007.

"Seasonic have always been known for their high-end range of silent PSU's. Will their latest 900w beast - the X900 unit live up to their reputation and our expectations?"

Quality review as always mate, and what an excellent performer. I'll have the stability and efficiency over other blingy high-powered units any day. Keep up the good work Quote

Mr. Smith
Almost 85% efficiency is very impressive.

Shame about the noisy fan, had they placed 2 fans in the unit - one intake, one exhaust - then the fans would not have had to reach full throttle like a single one does...
