SilverStone Strider Platinum Series 750W Power Supply Review

January 9th, 2016 James Leave a comment Go to comments

Overview

 

We’ve seen a few components from PC hardware giant SilverStone over the last few years from CPU Coolers to Cases, but not so many Power Supplies. But this next Power Supply is possibly one of the most interesting components so far, why? Well, apparently the Silverstone Strider Platinum Series 750W (SST-ST75F-PT) Power Supply is the ‘world’s smallest fully modular ATX power supply’!

The Silverstone Strider Platinum Series 750W Power Supply measures in at just 150 mm (W) x 86 mm (H) x 140 mm (D) making it (somewhat obviously) the smallest ATX Power Supply that we’ve seen here at pcG! This is the 750W version, 550W and 650W versions are also available. This is also the 80-Plus Platinum edition with both Titanium and Gold editions also available. The Strider Platinum Series 750W is a fully modular Power Supply and comes equipped with enough cables to power a dual Graphics Card Gaming system.

 

SilverStone ‘As desktop computers continue to advance toward ever more efficient and smaller designs, SilverStone is helping to drive the efficiency movement by releasing the Strider Platinum series of power supplies. Created to be the smallest fully modular ATX power supplies with 80 PLUS Platinum efficiency, they are also incredibly quiet with the ability to run in fanless mode. If the loading condition is below 20%, the fan in the power supply can remain off for silent operation during idle or low powered computing activities. Other great features inherited from previous Strider series include ±3% regulation, powerful single +12V rail, 24/7 continuous power output, and multiple PCI-E cables. For those looking to build highly efficient systems in small footprints, the Strider Platinum is definitely the best choice.’

The Silverstone Strider Platinum Series 750W Power Supply arrived at pcG in a smart looking predominately black box proudly highlighting the Power Supply’s 80-Plus Platinum efficiency rating and the fact that it’s the world’s smallest (fully modular) ATX PSU. In addition to this the front of the box shows us that this is a 750W Power Supply as well as highlighting the following features below:

  • Compact design with a depth of 140mm for easy integration
  • High efficiency with 80 PLUS Platinum certification
  • 100% modular cables
  • 24/7 continuous power output with 40℃ operating temperature
  • Class-leading single +12V rail
  • Strict ±3% voltage regulation and low ripple & noise
  • Ultra silent 120mm fan with intelligent semi-fanless operation
  • The back of the box is awash with information and images highlighting the same aspects of the Strider Power Supply that are shown on the front, in both English and various other languages.

    The sides of the box also offer up a little more information on the SilverStone Strider with the top of the box showing off the cables that the PSU comes equipped with and the bottom of the box highlighting the specifications (see Specifications/Features below) as well as the power loads permitted on each rail. Both the left and right sides of the box offer up very little other than the PSU brand, the wattage and the fact that this is the ‘World’s smallest 80-Plus Platinum full-modular ATX power supplies’, just in case you’ve not realised! 😉

    On opening the box we can see that the Power Supply and its associated accessories are adequately packaged, although I feel it could have been better, with the PSU simply covered with a bubble-wrap bag! Atop we find a specification leaflet as well as a SilverStone Power Supply manual, that seems somewhat generic. Hiding beneath the simple black cardboard section at the front of the box are the bundled cables and accessories.

    As you can see from the giant yellow warning label, the fan aboard the Strider will not spin until a certain temperature or Load is reached!

    Within the box, other than the Power Supply itself and the paperwork, we find the modular cables including European power plug, as well as some screws, cable ties and some Velcro straps.

    At the time of review the SilverStone Strider 750W Platinum Series Power Supply is available for approximately £121 on Amazon and comes with a 5 year warranty.

    First Impressions

     

    Silverstone Strider 750W

     

    First Impressions of the SilverStone Strider Platinum Series 750W Power Supply is that yes, it is small, very small indeed! It’s also nice that it’s also fully modular too! There’s very little else to say, other than the fact that the PSU looks well made and looks pretty good to boot! If it does what it says on the tin, then there’s no doubt that SilverStone will have a winner on its hands…

     

    Silverstone Strider 750W - top Silverstone Strider 750W - bottom

     

    NOTE: There may be some debate as to what is the top of a PSU as the physical top often features a fan, but when installed the fan normally faces down, now suggesting that this is in fact the bottom! So, from now on I’m calling the side with the fan the top! 😉

    Looking at the top of the SilverStone Strider we can see that it’s dominated by an offset 120mm cooling fan, with the centre of the fan featuring a smart SilverStone logo. The noise output of the fan is rated at 28dBA, although under certain circumstances (low load/temperature) the fan will not spin at all!

    The bottom of the Power Supply has a high quality black finish (as does the rest of the PSU’s casing) with an embossed SilverStone logo and name. The logo/name are also correctly orientated, assuming that you fit the PSU face side down and have a left side window in your case. I think they call that attention to detail…

     

    Silverstone Strider 750W - left Silverstone Strider 750W - right

    The left side (whilst looking from the back) of the SiverStone Strider is effectively featureless; the same black finish is present as is the version number, serial number and a few quality control stickers, that luckily all say OK! 😉

    The right side of the SilverStone Strider features a large sticker providing a host of information regarding the PSU, again this sticker is correctly orientated so you can read it when the PSU is correctly fitted, fan side down. Although having said that, there’s some argument for no sticker at all I think…

     

    Silverstone Strider 750W - back Silverstone Strider 750W - front

     

    The back of the Strider features a hole (haha, get it whole/hole!) host of holes in an attempt to improve airflow and keep the internal temperature down. In addition to this we find the main 3-pin power socket as well as a on/off switch in the top left corner.

    The front of the power supply is where we find all of the modular sockets, that are offset to the left to ease cable management (more attention to detail!), below the sockets there’s also a basic guide as to what each socket is for. Top left we have the main 24-pin socket, whilst to the right of this and bottom right, we have the x4 6-pin Molex and SATA power connectors. The two blue 8-pin (6+2pin) connectors are the PCIE power connectors for your Graphics Card/s, note that there are two so both SLI and Crossfire is supported. To the left of the blue PCIE sockets we have the single motherboard 8-pin power socket. Finally there’s this odd looking 4-pin socket at the far left, what’s that I hear you ask, a 4-pin power output? Nope! Important, please read on…

     

    Silverstone Strider 750W - cables Silverstone Strider 750W - Sensing cable

     

    Finally we have the cables that are supplied with the SilverStone Strider 750W Power Supply, this consists of a 20+4pin power cable, 4+4-pin power cable, x2 split PCIe 6+2 pin power cables, x2 four plug SATA power cables and x2 three Molex and one Floppy power cables (see Cable Details below for more details). All of the supplied cables are flat and a very flexible indeed and I rather like them, which is strange as I’m not normally a big fan of flat cables…

    But there’s something odd about the SilverStone Strider and that’s the fact that there’s another cable dangling off the MB end of the 24-pin plug!? This terminates some 550mm later in a single 4-pin plug (see above right). At first I thought this was an optional 4-pin power plug of some nature, but no! After reading the somewhat poor documentation supplied I was also none the wiser!? After some research I discovered that this cable needs to be plugged back into the PSU as it’s a sensing cable that feeds info back to the PSU regarding the voltages being supplied! Pretty important stuff, missing from the manual! 🙁 In fact you don’t need to plug it in if you don’t want to; I did some testing with it plugged in and out and all of my results were pretty much the same! Anyway, at least we now know what it’s for… 😉

    Overall then the SilverStone Strider Platinum Series 750W Power Supply seems to do everything right, apart from the information regarding that sensing cable perhaps! What SilverStone have done is create a very desirable Power Supply with a very small footprint that’s more than capable of powering a high end Gaming PC. As long as our testing goes OK, it would seem that this Platinum Power Supply might just get a Platinum award from us! Let’s see…

     

    Cable Details

    Hardware Installation

     

  • Test Rig Setup

  • Case Cooler Master HAF XB Power Supply Silverstone Strider Platinum Series 750W
    Motherboard ASRock Fatal1ty Z170 GAMING K6 CPU Intel Core i5-6600K
    CPU Cooler Noctua NH-U12S RAM G Skill Ripjaws 4 16GB
    Graphics Card EVGA GeForce GTX 980Ti Classified SSD HyperX FURY 120GB

     

    As you can see the SilverStone Strider 750W is significantly shorter than our regular Corsair AX760i that we use for testing and the Corsair is already a relatively short Power Supply at just 160mm long! All ATX based Power Supplies are 150mm (W) and 86mm (D) but the Strider is a further 20mm shorter than the Corsair. This will obviously help for installs within smaller M-ATX and ITX cases, but to be honest no one wants a physically big Power Supply anyway, smaller PSU’s simply mean easier installations and better cable management and possibly better cooling. Nice one SilverStone! 🙂 Silverstone Strider 750W - comparison

     

    Installation of a Power Supply is usually a straightforward and simple task. However installing into our HAF XB Test Rig case is usually made even easier, courtesy of a secondary PSU mounting bracket which allows for an additional 28mm to literally hang out of the back of the case.

    This means that by the time we’ve fitted the smallest fully modular ATX Power Supply in the world, there’s very little Power Supply actually in the case! Which of course is great news as now we’ve now got plenty of room for the cables. Although due to their flat nature and their high degree of flexibility, they’re even easier to manage than normal. Only a slight whinge, in that the plugs were very tight in the sockets on the PSU end. Conversely, they were very easy to fit on the motherboard side, strange…

     

    Testing Methodology/Setup

     

    When it comes to testing Power Supplies there’s very little else you can do other than put the PSU under load and measure the voltages. As this is not a very real world test (as it only takes seconds to setup and record), we have employed a more real world test. For more details on our thoughts regarding Power supply testing check out this article.

    The Power Supply is put under a real world load for 1 hour, while running both Unigine Heaven and running Prime 95 (Blend) simultaneously. Power Supplies under 750W are tested with a single EVGA 980Ti Classified GPU while Power Supplies of and over 750W are tested using two EVGA 980Ti Classified Graphics Card to ensure the PSU gets a real workout.

     

    Hardware Performance

    As you can see from the above images, the SilverStone Strider Platinum Series 750W Power Supply did well in our burn-in tests. In our single GPU test the voltages were stable at (3.312v, 5.064v & 12.000v). When we leaned on the Strider’s single 12v rail a little more, in our X2 GPU test, these voltages deviated a little more with voltages of (3.280v, 5.040v & 11.808v). All voltages were well within the ATX guidelines though, which allow for a 5% fluctuation. Throughout testing and during the week long test period no signs of instability were encountered.

  • x1 EVGA GTX 980Ti Classified


  • The maximum power draw (at the wall) during testing was recorded at 430.8 watts, suggesting that this Platinum rated Power Supply was delivering approximately 405 watts to the system due to its 94% efficiency at an approximate 50% load.

    Silverstone Strider 750W - x2 GPU power consumption
  • x2 (SLI) EVGA GTX 980Ti Classified


  • The maximum power draw (at the wall) during testing was recorded at 671.5 watts, suggesting that this Platinum rated Power Supply was delivering approximately 611 watts to the system due to its 91% efficiency at an approximate 100% load.

    Final Thoughts

     

    The Silverstone Strider Platinum Series 750W is the world’s smallest fully modular ATX Power Supply. It’s got a power output of 750W (enough for a dual GPU system) and it’s got a Platinum 80-Plus efficiency rating! I don’t think I need to say much else…

    The Silverstone Strider Platinum Series 750W Power Supply arrived at pcG in a smart black box with the components within being adequately packaged. Once out of the box the sheer (lack of) size becomes apparent. At just 150 mm (W) x 86 mm (H) x 140 mm (D) the Strider is indeed very small, in comparison our test Corsair AX760i measures in at 160mm long, 20mm longer than the Strider. If you bear in mind that the AX760i is already a relatively short PSU (that’s why we use it) we can begin to appreciate just how small the 750W Strider actually is. And the small size is important, as it simply means that this PSU is going to be easier to install than any PSU you’ve used before and that has to be a good thing. Of course this is especially true if you’re building a small form factor Gaming rig…

    The SilverStone Strider is also a decent looking Power Supply (as far a power supplies goes that is!) with its matte black finish and some well placed and appropriately placed stickers and logos etc. The cables are pretty good too! Yes they are flat (something that I not normally a fan of) but they’re very flexible indeed and as they’re flat they can be orientated to aide in airflow too! My only real complaint about the SilverStone Strider is the fact that Silverstone provided very little information (READ None!) regarding the Sensing cable that has to be plugged back in to the PSU from the motherboard. This (apparently!) helps stabilize the voltages as the PSU monitors them! The fact that this important information seems to be missing from any documentation though is simply bizarre!

    When it came to the SilverStone Strider’s performance as one would expect the Power Supply performed well. Pulling 430W at the wall in our x1 GPU Stress Test and just 671W in our x2 GPU Stress test. All voltages (3.3v, 5v & 12v) were also stable during both tests, with the highest deviation being 3.280v, 5.064v and 11.808v. Although, all of those voltages are well within ATX guidelines.

    I’ve always thought that Power Supplies should be smaller as it simply makes for an easier installation, especially when installing into smaller form factor cases. Well it would seem that SilverStone were privy to my thoughts! The Silverstone Strider Platinum Series 750W seems to tick ALL of the boxes; it’s the world’s smallest 80-Plus Platinum fully modular ATX PSU, add to that its impressive power output and its Platinum 80-Plus rating and a fair(ish) price! The only thing letting it down is that 3 year warranty as that’s a fair bit less than some of the competition that are offering 5 years and beyond…

    Bottom line is that the SilverStone Strider Platinum Series 750W Power Supply is well worth tracking down as it simply enables you to build a powerful and efficient Gaming system, while taking up very little space.
