Final Thoughts and Conclusions

The SilverStone Strider Platinum Series 1000W power supply performed very well during our testing. We found the overall efficiency of the power supply to be excellent and easily meets the rigorous 80 Plus Platinum criteria for high efficiency, even while operating on 120 VAC and at elevated temperatures.

The voltage regulation delivered by the ST1000-PT is also very good across the board. All of the main DC outputs stayed well within SilverStone’s claimed ±3% range with the three primary rails measuring ±2%. AC ripple and noise suppression is also very good. The power supply is silent at low power levels and remains very quiet through mid-power operation. Only at the full 100% load did the fan noise really become noticeable. The ST1000-PT comes with a very good assortment of all-modular, ribbon-style cables with two ATX12V 4+4 pin/EPS 8-pin, and six PCI-E connectors for multiple graphic card support, each on their own cable.

Bottom line, the SilverStone Platinum Series 1000W power supply delivered very good performance and deserves serious consideration if you need a lot of power for your next build.

MSRP for the SilverStone Platinum Series high output power supplies:

•    SilverStone ST1000-PT (1000W): $189.99 USD
•    SilverStone ST1200-PT (1200W): $239.99 USD

•    1000W or 1200W continuous DC output
•    Excellent efficiency (80 Plus Platinum certified)
•    Very good voltage regulation (±2% confirmed)
•    Clean DC outputs with low AC ripple/noise
•    Very quiet operation below ~60% load
•    All-modular cable design with flat ribbon-style cables
•    Universal AC input with Active PFC
•    5-Year warranty

Minor Weaknesses:

•    Modular 6-pin peripheral cable could accidentally be plugged into an 8-pin EPS connector
•    Standard enclosure measures 180mm (7.1”) deep

SilverStone Strider Platinum Series 1000W Power Supply

I would like to thank our friends at SilverStone for sending us the Platinum Series 1000W PSU to review – thank you!


Edit 12-27-2016: In response to a question posed by one of our observant readers, we went back and checked all three SilverStone Strider Platinum Series power supplies we have reviewed (ST55F-PT, ST85F-PT, and the ST1000-PT) to see if it was possible to accidentally plug one of the modular cables into a connector it was not intended for.  We found that none of the connectors on the four compact chassis models (550W thru 850W) could be inadvertently mixed up. However, for the two high-power models (1000W and 1200W) it is "possible" to plug one of the 6-pin peripheral cables into either of the 8-pin EPS slots because of the extra wide key slot.

I contacted SilverStone and asked why the key slots were made over sized on the 8-pin EPS connectors and they said that was a carry-over from earlier models and was done to allow either end of the cable to be plugged in (the 4+4 pin end has double keys). They also informed me that this was an oversight on their part and have issued an engineering change order to correct the issue on future product runs. Any damage caused, even though it was accidental, would be covered under warranty.

While I feel it is very unlikely that anyone would actually do this, it is nice to see a manufacture willing to admit their mistake, take quick corrective action, and stand behind their product.
