From what I’ve seen and the specifications laid out, the cooling method – air, via the 120mm fan – appears to be adequate for most scenarios, though I always keep an eye on thermal performance, which can vary based on the build and room temperature.

In my toolbox of power supplies, the Strider Platinum series has marked itself as a noticeable contender. It offers a blend of efficiency, power, and forward-looking features that many enthusiasts and professionals will appreciate, albeit with the recognition that the premium for efficiency and compact size might not align with every builder’s needs or preferences.

Power and Efficiency

When it comes to building a PC, the power supply is a crucial component that often doesn’t get the level of attention it deserves. I’ve spent considerable time researching and the SilverStone Strider 850W 80+ Platinum Modular PSU caught my attention for a number of reasons. Its promise of combining both power and efficiency in a compact package is particularly appealing.

Key Advantages of the Strider Platinum PSU:

  • 850 watt maximum output, suitable for high-end systems

  • 80 plus Platinum certification for energy saving

  • Full modular design for a clean build

  • Fanless mode capability under low load for silent operation

However, it’s important to dissect these features a little bit to see how they translate into real-world use. Starting with the 850 watt output, it’s more than enough for most gaming setups, even those with multiple graphics cards. This aspect gives me peace of mind about future upgrades or expansions, knowing I won’t need to replace the PSU.

The Platinum certification is synonymous with high efficiency, which not only helps with energy cost savings but also means less heat is generated. This is especially important for me, as I tend to favor builds that are both powerful and sustainable.

I appreciate the fully modular cables as well; they’re a boon for cable management, allowing me to use only the cables I need, which also aids in better airflow within the case.

However, while the PSU can operate in fanless mode when under 20% load, for me, this point is more of a nice-to-have than a make-or-break feature, since most of my computing activities involve more than just idling or light uses.

For a PSU, it’s quite quiet thanks to the ultra-silent 120mm fan, even when it kicks in during heavier usage. As someone sensitive to noise, this is a significant plus.

On the flip side, despite so many benefits, there is a cost premium for the 80 Plus Platinum efficiency and brand reputation. Budget-conscious builders may look towards more affordable options, though I believe the energy savings could offset the initial investment in the long run.

Also worth noting is that the small size (5.9 x 5.5 x 3.4 inches) is an impressive feat of engineering, considering the power it packs. It definitely frees up more room for other components or even smaller case options.

In all, SilverStone’s Strider Platinum is a strong contender for those valuing a balance of efficiency and power in a small form factor. Sure, the price might be a bit steep, but for a build that’s likely to stay relevant for years, it seems like a worthwhile investment.

Design and Compatibility

The SilverStone Strider 850W 80+ Platinum Modular PSU impresses with its thoughtful design and compatibility features, which make it a compelling choice for building a high-efficiency, compact PC system. Here’s a rundown of my observations on these aspects:

  • Size: The compact size of 5.9 x 5.5 x 3.4 inches is ideal for small form factor builds. This is quite an achievement for a fully modular PSU, allowing for a tidy setup and efficient use of space.

  • Modularity: The 100% modular cables are a huge plus. It gives me the freedom to only connect the cables I need, which helps airflow and reduces clutter.

  • Compatibility: Compatibility with ATX12V v2.4 means it will work with most modern motherboards. It should fit seamlessly into most current systems without issues.

On the downside, for those who have a heavy reliance on legacy connectors, this PSU might not be the best fit. The fact that the connector types focus on HDMI, USB, DVD, HD, AC, and DC means it’s more geared towards modern devices. If you’re running older hardware that requires different connectors, it might require purchasing additional adapters.

The ultra-quiet operation of the 120mm fan can’t be overstated. I appreciate a silent workspace, so having a PSU that can operate in fanless mode under low loads is a major advantage. Nonetheless, while the unit remains silent during idle or low-demand tasks, some might find the fan noise noticeable during intense operations, which could be a minor drawback for sound-sensitive users.

The Strider’s small stature and 6-pound weight make it appealing to those who frequently modify their setups or attend LAN parties. However, its weight might be a bit on the heavier side when considering the smaller size—something to keep in mind if weight is a critical factor for your build.

In the realm of form factors, the ATX and ATX12V standards ensure broad compatibility across a multitude of cases and motherboards, affirming the PSU’s versatility. Yet, for those seeking to integrate this PSU into non-ATX compliant cases, this might limit the applicability.

Overall, the SilverStone Strider Platinum series comes off as a reliable, efficient choice for power supply units. Its 850 watts of output is generous for most gaming and professional workstations. I’m inclined to view it positiively, especially for those prioritizing efficiency, modern connectivity, and a modular design in a compact space. Although, as with any product, it’s important to weigh these strengths against any potential limitation it may pose to specific individual needs or setups.

SilverStone Technology’s dedication to performance and silence in the Strider Platinum series power supplies is commendable. The balance of thermal and noise management is crucial in a power supply, and it’s often a deciding factor for me when building a PC. Here’s where things stand for the Strider Platinum 850W:

  • The 120mm fan with its semi-fanless operation is a strong selling point. It remains inactive under 20% load which ensures a silent performance during light computing tasks. This is a relief when I’m working late at night and prefer not to have the constant hum of fans in the background.

  • When the fan does run, it’s still ultra silent. The noise is minimal, and often blends into the ambient room noise, which is quite impressive for an 850-watt unit.

  • The power supply operates confidently at a continuous 40℃ which is a decent threshold for most environments. The promise of 24/7 operation without faltering under a reasonable thermal load gives peace of mind for system stability.

However, even though the fan is generally quiet, I’ve noticed that when the unit is under substantial stress, noise can be perceptible. It’s not a deal-breaker but worth noting for users who are particularly sensitive to sound.

In terms of thermal performance, it holds up well. I haven’t encountered any overheating issues and it seems to dissipate heat effectively. While I don’t push my PC to extreme limits regularly, I am confident that the Strider Platinum won’t buckle under pressure based on my experiences thus far.

Summing up these observations:


  • Excellent silent operation at low load.

  • Adequate cooling for most scenarios.

  • Fan noise blends with ambient noise, barely noticeable.


  • Noise levels can become noticeable under heavy load.

It’s worth mentioning that managing the acoustics in a power supply while maintaining high efficiency is a delicate balancing act, and SilverStone seems to have found a good middle ground with this model. The only time I might be cautious is during those marathon gaming sessions that push everything to their limits.

In conclusion, the thermal and noise performance of the Strider Platinum 850W is quite consistent and dependable. The semi-fanless feature is ideal for users who, like me, appreciate a quiet computing environment, and it’s reassuring to know that the fan will only kick in when absolutely necessary. In my book, these factors make it a trustworthy companion for my computing needs, even with the slight increase in noise during intense use.
