80 PLUS Gold: Four Efficient 700-850 W Power Supplies

Measurements: SilverStone Strider Gold SST-ST75F-G

Efficiency according to 80 PLUS specifications

Efficiency based on performance profiles

The SilverStone Strider Gold can't keep up with its competitors in terms of efficiency. At 100% load, it misses the 80 PLUS Gold limit by one percent; at 50% load it misses by two percent. To eliminate the possibility of error or a bad sample, we repeated the test with a second unit, which returned identical results. Granted, this isn't too important in the real world, but it's still off-spec.

The SilverStone Strider Gold 750 is certainly a good PSU, and it delivers more than enough power, even for demanding systems. The fully modular cable solution is also an interesting feature for the folks who prefer particularly clean innards. But the efficiency lapses cannot simply be ignored, especially with a street price of roughly $190. SilverStone only offers a three-year warranty, while the other manufacturers offer five.

    Every now and again you can catch the Seasonic X series on sale. I picked up a X-650 for about $110 with shipping. For that price, there isn't really anything better. With out a sale, I still say full modular and 80+ Gold is worth the premium over less auspicious contenders.

    Thanks for an excellent review.

  • on the seasonic X-760 introduction, the first paragraph states that it comes with hard-wiring. But if you look at the pictures, and further down the review, you'll notice that it is fully-modular.

    no pun intended here ;-)

    I've used the X 650 in builds for two of my friends. I can't wait to get mine. The cabling is perfect for the Antec 1200 case.

  • What about noise? Only had a quick glance at the article but that didn't seem to have been measured.

    Great review, but where is Corsair???? Certainly Corsair is one of the industry leaders and most recommended PSUs on the market.

    This review would have benefited greatly by including both silver and gold rated PSUs from 750W - 1000W. Some Silver rated PSUs actually perform at nearly at gold levels (Corsair) and so they are a great value.

    It would have been nice to have some expert comment on Au's claim that a non-modular cable setup improves efficiency. This appears to be a myth because we see many modular units outperform non-modular units in their class.

    Still I really enjoyed this review.

    Not to forget is that a 80+ PSU generates about twice the heat of a 80+ Gold PSU, 20% compared to 10% of the power output. So a gold certified PSU should be significantly more quiet then a 80+ given equal cooling.

    flongGreat review, but where is Corsair???? /citation]Corsair don't build there own PSU:s the are mostly Seasonic built, some CWT. For example the Corsair AX series are nearly identical to the Seasonic X series, the only difference is the fan.

    I have a SeaSonic X-760 fitted to an O/C'ed i7.

    The 'fan-on' at 20% (i think without looking back) is worst case, mine kicks on at about 30-35% depending on ambient temp, so its awesome quiet. Even when on its quiet.

    It works very well in a dual gaming/home cinema box...

    I'd definiately recommend one
