When most people build a gaming system, usually most of their money goes to buying a powerful video card and processor and spending as little as possible on a power supply. It makes sense to spend most of your money on a video card and processor because those two components have a big impact on your gaming experience but what most people forget, is that the power supply is one of the most important component in a PC. Cutting corners when purchasing a power supply can prove fatal for your system and you must make sure you purchase a quality power supply from a reputable company.

The problem is that many people have no idea which power supply to use in their system and they simply end up buying some random power supply they find on websites such as Amazon and Newegg. There are three major things you have to look for when shopping for a power supply: power output, efficiency and manufacturer. There are a very large number of cheap, no-name power supply products out there and many of which should be avoided at all costs. A no-name power supply can take down other components in your system and it's often more expensive to buy the cheapest unit because of the increase in electricity cost in the long run. A higher quality power supply will typically be more efficient and pay for the difference in price over time.

SilverStone is not just known in the industry for making great computer cases but also for making high quality reliable power supplies. The SilverStone power supply line are comprised of the Strider, SFX, Nightjar, Gemini and Zeus model lines. I interviewed Tony Ou, SilverStone's marketing manager, a few months ago and asked him some questions about computer cases, power supplies and other upcoming products from SilverStone. Head over here if you are interested in reading my interview with Tony Ou.

SilverStone ST75F-PT PSU

Today we are going to look at the SilverStone Strider Platinum ST75F-PT power supply that retails for $154.99 and comes with 5 years of warranty. SilverStone displayed the ST75F-PT at CES at the beginning of 2016 and it received a lot of positive attention. The Strider Platinum line ranges in capacity from 550W all the way up to 1200W. The ST75F-PT is a 80+ Platinum certified PSU, fully modular and comes in a compact design that delivers 415W per litre. It has a silent 120mm fan with intelligent operation with the ability to run in fanless mode and comes bundled with flat black cables. The fan in the power supply turns off for silent operation during idle or low powered activities if the loading condition is below 20%. The first thing you will notice about the PSU is Silverstone's logo in the middle of the rounded wire grill.

Another feature include ±3% regulation, powerful single +12V rail, 24/7 continuous power output, and multiple PCI-E cables. SilverStone has designed the ST75F-PT for those looking to build efficient systems in small footprints. The ST75F-PT has a 40 Celsius max temperature rating. Some of the high quality PSUs are rated for 50 Celsius intake temperature but that doesn't mean the ST75F-PT won't operate above 40 Celsius, it's just that the fan profile is optimized for temperatures under 40 Celsius. The 50 Celsius rating is a pretty difficult standard to meet and the majority of the PSUs out there are rated for 40 Celsius.

Looking at the power specifications below, the single +12V rail can deliver up to 62.5A, so it's got plenty of power to handle a couple of high-end video cards. In case you are wondering, power supplies with multiple +12V rails are infact just a single +12V rail split up each with a limited output capacity. Splitting up a single +12V rail into multiple rails is done for safety reasons. It's safer to limit the current through multiple rails so that each wire can carry a limited load without getting too hot than to have one single +12V rail. Both single and multiple rails have their advantages and disadvantages. The biggest advantage a single rail PSU has over a multiple rails PSU is that you don't have to worry about which rails are connected and most single rail PSUs are of higher quality. But this is also a big disadvantage when it comes to fault tolerance and safety.

The PSU comes in a simple but elegant box and on the front we see that the ST75F-PT is world's smallest 80 plus platinum. On the back, you will see a couple of graphs illustrating the features of the PSU such as the efficiency, size difference between a regular PSU. Since this PSU features a compact design, it makes it ideal choice for enthusiasts with compact cases. The dimensions are 150mm in width, 86mm tall and 140mm deep and weighs 2.25 kg.

SilverStone's packaging has always been very good and this time it's no exception. We can see that the ST75F-PT is protected by two high density foams as shock absorbent and plastic wrapping to prevent any accidental damages during shipping. SilverStone has put a yellow tape around the PSU that says the fan will not spin during operation until certain load or temperature is reached. The ST75F-PT features a nice clean, flat black paint job that's really attractive. There's a void sticker on one of the corners of the PSU and tampering with the PSU of course voids the warranty.

The accessories included are Velcro straps, two sets of bolts, a couple of zip ties, an AC power cord and two manuals. The manuals have all the information that you need to know about the power supply. The black manual has basically information on how to set up your power supply in all the languages and it's pretty generic. The white manual on the other hand is where all the interesting information is about the PSU and it tells you everything you need to know about the PSU. It's perfect if you want to learn how PSUs work and how to troubleshoot them and it will make you a more informed enthusiast user.

All cables are flat and are of plenty ample length and feel high quality in hand. Flat cables have much greater flexibility to allow for tighter folding and management of cables. This PSU is compatible with SilverStone’s PP05 which can be used to reduce cable clutter in smaller cases and all cables are wrapped in super flexible mesh. I strongly recommend the PP05 kit if you are going to be building a small form factor computer so you won't have to deal with the added clutter of long cables.
