Silverstone Strider Gold S Series ST85F-GS


Since being founded in 2003, Silverstone have brought us many high quality products, including revolutionary fan designs, high quality and sometimes niche cases, along with well built and affordable power supplies.

Over the past few years, Silverstone have brought us a fair few mATX, and mITX cases, such as their Sugo range along with ranges aimed at the HTPC market. It’s actually amazing to see just how many of these Silverstone have released, along with the amount of design work that’s gone into every one of them.

In order to support these, Silverstone have also been prompt in releasing compact power supplies, along with shorter cable kits, as they clearly understand the horrors of having to route ATX length cables around an ITX system.

TTL takes a look at one of the new entries into the Strider Gold S series; the ST85F-GS, complete with the matching PP05-E short cable kit, making this ideal for use in compact systems.

ITX motherboards are very common these days, and we are now seeing more and more high powered mATX and mITX systems. With the release of the R9 290X and the GTX780Ti, along with high performing motherboards such as the Asus Maximus VI Impact, there’s no longer a need to have a full ATX system with an SLI or Crossfire graphics solution in order to get a great performing system. We think this new range of power supplies is the perfect way to support this.

The S series are gold rated units, and are available from 550w to 850w, whilst maintaining the minimalistic, sleek look on the outside, as well as being only 150mm long. In certain cases such as the Bitfenix Prodigy, larger power supplies simply won’t fit in most circumstances, and if they do, you’re often left with next to no room to work with the cables and so cabling becomes a nightmare. With the ST85F-GS, this is no longer an issue as the modular flat cables make things easy to work with, and the short design of the power supply means you have even more room to work with. The the 850w output is able to power any single GPU on the market, from the Titan, to the previous generation dual GPU cards such as the GTX690, or the AMD 7990, and so regardless of what you want to put into a compact system, the ST85F-GS will have you covered.

Along with being shorter and more compact than most power supplies, the ST85F-GS (like most Silverstone power supplies) is fully modular. This is especially beneficial in the more compact systems since unnecessary cables won’t get in the way, however, if you want to use this for a full ATX system, then the modular cable system will again aid in cable management, as well as aesthetics. The modular cables also allow for the standard cables to be replaced with the PP05-E short cable kit from Silverstone. These cables are only around 30-35cm long making them ideal for use with a small system. In a case such as the Bitfenix Prodigy M, where the power supply sits in the front of the case, there’s a very short distance between the end of the power supply, and the GPU and motherboard power connectors. This means longer cables obstruct airflow onto the graphics cards, and as well as increasing temperatures, this will be detrimental to aesthetics. With the short cable kit however, excess cabling will be minimised and airflow won’t be blocked. This will make things look a lot tidier inside.

The power supply itself comes with 2x8pin CPU, 1x24pin Motherboard, 4x8/6pin PCIE, along with 8 SATA and 6 Molex connectors, meaning you’ll have plenty of connectors to support even the most powerful of systems. These cables are all flat design, so they won’t interfere with airflow, and they’ll also be far more flexible than standard cables.

Overall, these units are incredibly well built, and like all Silverstone products, they keep a sleek design. If you’re looking to power a high end compact system, then the Gold S Series with the PP05-E short cable kit should definitely be under consideration.

Thanks to Silverstone for providing the PSU and the cables. You can discuss your thoughts on the OC3D forums.
