To meet the requirements of current and future desktop computers, SilverStone created the Strider Gold S series power supplies. The Strider Gold S models are all new designs engineered to be the smallest, full-modular ATX power supplies at any wattage levels. The Strider Gold S series includes wattage range from 550W to 1500W for a great variety of applications. With short depth designs, all models in the series are among the world?s smallest full-modular ATX PSUs. In addition to 80 PLUS Gold level efficiency, the Strider Gold S PSUs are built to meet very high standards in electrical performance with ?3% voltage regulation, ?3% ripple & noise, and high amperage single +12V rail. Other notable features included are 24/7 40?C continuous output capability, low-noise fan, and multiple sets of PCIe cables. For users looking for a power supply with faultless combination of compact size, performance, efficiency, and quality, the Strider Gold S Series is the only choice.

    Nothing else like this exists. High power output, platinum rated efficiency, and only 140mm length. That’s unheard of. I paired this with Silverstone’s short cable kit and a Fractal Design Node 304 case. Fit perfectly allowing for maximum length GPUs. This allows me to build a very compact, but not cramped, top end gaming system.

    This is powering an Asus Maximus VIII Impact, i7 6700k, 16GB of Corsair Vengeance LPX DDR4, an MSI GTX 980 Ti Gaming GPU, and two Samsung SSDs. All within a Fractal Design Node 304.

    On idle and light load, the fan isn’t even on, so it’d dead silent. Under full load, I can’t hear it. The GPU is the loudest thing in my system.

    There are a few technical reviews out there already that show this is a very good PSU. The only negatives they’ve stated is the 3 year warranty. Most other PSUs from known brands offer closer to a 10 year warranty. This is also rated for operating temperatures of up to 40 C, while most other PSUs from known brands rate closer to 50 C, but I doubt that will matter for most people.

    If you found this, you probably already know, but this power supply is 80+ Titanium rated. 80+ ratings are about power supply efficiency, and power supply efficiency is a HUGE factor in how much power your computer uses. Titanium is the highest rating and, while it includes slight increases in required inefficiencies at 20%, 50%, and 100% of rated load over Platinum, the second highest rating, it also includes something that no other 80+ category includes: minimum efficiency at 10% load. This is important because your computer likely spends a lot of time at low loads, and the nature of power supply design is that this isn’t easy to achieve.

    So far I’ve noticed that the supply is quite quiet, and I’ve loaded it up pretty well and burned it in, so I’m hoping not to experience any early life failures. I don’t have the test equipment to verify that it’s actually meeting its efficiency targets, but quiet is a pretty good sign that it’s not turning a lot of extra power into heat.
