SilverStone ST1200-PTS Strider Platinum 1200W Power Supply Review

I had mentioned that this 1200W Platinum PSU was smaller than the previous version and to give you some indication as to just how much we have a “old” Corsair HX 850 sitting being the SilverStone 1200W PTS.  As you can see there is a rather definitive difference In terms of size.  The PSU is also lighter weighing only 2kg which may not sound like much however in a fully built custom PC every little bit matters.

SilverStone includes a magnetic fan filter that is made from an ultrafine mesh that appears almost transparent and does an excellent job at catching dust.  Of course most modern cases come with a PSU fan filter so you can reuse the filter on another fan or simply leave it in the box.

The SilverStone Strider 1200W-PTS Platinum is a fully modular power supply meaning that every single cable can be removed.  For those building in a SFF case SilverStone sells custom cable kits for the Strider Series that are shorter and easier to route when space is limited.  You also have the option to go with a custom cable kit from a vendor like CableMOD or build your own.  Something you cannot do without a fully modular PSU design.

Overall the PSU follows a strict voltage regulation of +/- 3% to curb any power spikes and the same +/- 3% ripple and noise control.  Of course testing these can be difficult but basically this means the power is clean and will prevent any ground loops from causing issues with your components.

The SilverStone Strider Platinum is a single rail design with the 12v rail supporting a 100A circuit with a maximum RMS power output of 1200W.  As part of the 80 PLUS Platinum certification the PSU must be between 89% and 92% efficient while the power supply is operating between 20% and 100% load.  If you match your PSU properly there is a very strong chance that the included fan may never turn on and is one of the arguments for buying a big PSU.
