SilverStone Releases New Gemini Series 500W+500W Mini Redundant Power Supply Unit – GM500-S

Taipei, Taiwan, February 23rd, 2021 –SilverStone Technology, an established leader in the PC component field, is excited to announce the availability of the new Gemini Series 500W+500W Silver Mini Redundant power supply unit (PSU), providing new and improved models for users with mission critical servers and computers where shutdown or failure isn’t an option.

There are many systems that need to remain operational around the clock, so it is vital for them to have reliability and redundancy from the power supply. This is where the GM500-S comes in as it combines proven industrial grade components, 80 PLUS Silver certification, Japanese electrolytic capacitors and inclusion of PMBus 1.2, all stowed inside a PS/2 frame with a depth of 174mm. The GM500-S is capable of 500W+500W 24/7 continuous power output at 50°C while maintaining compatibility with majority of cases on the market.


GM500-S features dual 40mm DC fans to cool internal components and a hot-swappable design with convenient handle bar on each PSU, so in a case where one PSU dies, this design makes it convenient for users to pull and swap out the defective one seamlessly, all while the second PSU is keeping the devices operating.
