Silverpower Gorilla 400W


Maxpoint is responsible for brands like Tagan that have sold well in Europe during the last years. Maxpoint then opened an office in the U.S., which is why Tagan is also available here as well. Silverpower is a newer venture from Maxpoint to cover the lower end market. Maxpoint has the exclusive rights for Seasonic in Europe, which is why the idea came up to ODM from them. The name for this unit is actually not clear since Maxpoint told us Gorilla, or King Kong, or Kong on different occasions. This unit will probably never see the U.S. market but we thought it might be a good addition even if it's only for our readers in Europe.


The Silverpower 400W is based on Seasonic's S12 design. Since we have a 120mm fan in this power supply, the fins needed to be opened and not like the PCP&C Silencer series. In fact, this power supplies is almost the same as the Silencer since they share the same basic topology. Instead of Nippon Chemi-Con, the Silverpower sports a main cap made by Hitachi and the secondary caps are from Ostor.

Maxpoint really equipped the Silverpower Gorilla well, with more cable harnesses and connectors than most of the competition. The main ATX connectors are at the 50cm mark and both (yup - two of them) PEG connectors are at 55cm. The other connectors are spread on two cable harnesses at various distances.

    How can Silverstone Element ST40EF 400W get so good score on quietness and efficiency compared to Silverstone Element Plus ST50EF-Plus 500W?
    This (SPCR) review says Silverstone Element Plus ST50EF-Plus not that quiet or efficient:

    Could you comment on this PSU? I know you have a 500 and 550w article coming up but an incredible deal ($25 after rebate) came up on this PSU and I'll snatch it up for my build if it's good.

    Thanks.

    As usual, thank you for your interesting review and the effort you surely put into it!

    This is the kind of article I like to keep in my favorites and refer people to. Reply

    I skimmed through, but I didn't see what type of set-ups you'd recommend for this class of PSU.

    So, I'll post what I'm using with a Corsair vx450:
    Q8200 @ 3.3ghz (475x7)
    8gb Ballistix DDR2-800 cas4 @ 475mhz (4x2gb)
    Evga 9800gtx (stock clocked for now)
    Gigabyte P-45 UD3P
    3 x 7200rpm sata disks
    2 x DVD/RW
    3 x 120mm fans

    It's been running fine for almost a month now (thanks MS for the 30% eBay cashback lol). I previously used this vx450 in my first build (s939 Opteron/7600gt).

    The VX450 is a pretty good PSU and under optimal conditions you can probably draw more than the max. rated wattage (450W @ 50C ambient). Though personally I like to go with a bit more headroom taking future upgrades into consideration. Reply

    That's another way to group the power supplies.
    That's one reason I still use Enermax Liberty power supplies...they're a nice small size for HTPC's and the modular connectors are important when there isn't much space. Using this affects power efficiency which is probably why the highest efficiency ones don't use them...

    its a very nice test, i like it. i miss some words from the ripple side, they could be useful to those, who don't want to analyze so many graphs.

    i have an FSP 500 GLN60 (active pfc, smooth oemgrey color:D), i wanted a BS2, but the two seems to be identical to me (ok, it only has one 6pin connector). and i'm out of connectors (6molex, 4sata... with 7 HDDs/opticals, 2 fan controllers and only one video card). so having many connectors is a good thing, although you can buy molex duplicators (only downside is they cost money). and its still more than enough to power my system (q6600@3.0, hd3870, lots of vents, hdds...).

    and most of the computers are fine with just 200-300W. its a shame, that there aren't that many good PSUs on the low edge, because having a monster of PSU means you will have bad efficiency in idle with most of the computers. ofc you can build a computer, which eats up 1000W, but besides skulltrail its hard, and mostly needs enthusiast end water cooling/compressor for cooling purposes.

    and having a good PSU is like having good safety in your car: you only notice it when it fails, but then it is already too late. and buying a noname PSU means that you playing russian roulette all the time...

    I find it weird people keep recommending Sea Sonic. I'm currently loojing for a new PSU in the 500-600watt range. I remember toms 24 hour PSU stress test, where Enermax, Zalman, Cooler Master and Silverstone where the last remaining, while Seasonic had failed with the rest.

    I just read Hardocps Seasonic S12II-500 watt psu review, and the transient load test showed awful results.
    http://hardocp.com/article.html?art=MTM2NCw3LCxoZW...">http://hardocp.com/article.html?art=MTM2NCw3LCxoZW...
    Think computer showed a lot of undervoltage ripple too, and on the 12v a lot of switching between overvoltage and undervoltage. That doesnt look good.
    http://www.thinkcomputers.org/index.php?x=reviews&...">http://www.thinkcomputers.org/index.php?x=reviews&...
    And i have read about the DOA Seasonics too, and the ones failing after some time...
    Seasonic also only provide 3 years of limited warrenty here like many other places, while a brand like Cooler master give 5 years, just like Corsair.

    Just makes you wonder.
    I think i'll go with an Enermax modu+ or pro+ this time..still not sure though.

    Hmmm... your first link is to the german side of Tom's, and while we can make out perhaps the SeaSonic PS failed, searching the English side for the same article does not yield a proper counterpart, and the article that comes close to it, is not even finished and broken. What does that say about Tom's Hardware?

    Your second link does show some iffy parts, but overall, they recommend the power supply and dismiss the transient load results as not important. Btw, you think a computer motherboard is going to fry because the 12v line varies 0.2v? 4.92 volts is bad? Those voltages can vary 10% on the 12v line and 5% on the others and meet Intel's ATX spec. Welcome to the real world of imperfection.

    Three years vs 5 years, so what? My FSP power supply in the thrid computer I've built in 2001 still runs fine, and it came with only a 1 year distributor warranty. In fact, only 1 out of 10+ FSP power supplies died, and it probably died because the power strip blew.
