Introduction and Features
In this review we are going to take a detailed look at FSP Technology Inc.’s new Twins 500W redundant power supply. It’s been quite a while since we reviewed a redundant power supply in the ATX form factor. This should be interesting! (Actually, it turned out to be very interesting, along with a few surprises we didn’t expect).
The FSP Twins 500W redundant power supply is targeted towards use in home and small businesses for mail or web server systems that require maximum up time. The Twins 500W PSU incorporates two 520W modular power supplies inside one standard ATX housing. Under normal operation the two power supplies operate in parallel, sharing the load. If one of the power supply modules should fail, the other one automatically takes over with no down time. And since the power supply modules are hot-swappable, a faulty unit can be replaced without having to turn off the system.
FSP claims the Twins 500W is a server-grade power supply designed to deliver stable power and is certified 80 Plus Gold for high efficiency. The ATX chassis measures 190mm (7.4”) deep and is fitted with fixed, ribbon-style cables. Each modular power supply uses a 40mm fan for cooling and the Twins 500W comes backed by a 5-year warranty. Users can also download and install FSP’s Guardian software to monitor power input, power output, and efficiency, along with other parameters in real time if desired.

If you are running a server at home, for instance a PLEX server, which you access while travelling and need it to stay up 24/7 you may have looked into redundant PSUs. They tend to be expensive and do not easily fit into a standard case, let alone a SFF one. FSP Group has a solution they call The Twins.
The Twins are a pair of 500W PSUs in a casing that will fit in most cases, the width and height are the same as a normal ATX PSU, the length of 190mm might be an issue for some cases however. They are fully hot-swappable and offer redundant power so that if one happens to go out your system will continue to run.
This 500W unit and the following 700W unit are both 80 PLUS GOLD certified and come with a USB header connection which allows you to use their FSP Guardian software. FSP Guardian allows you to monitor real time power input, power output, efficiency, and other specs and saves the data for 30 days to let you see how your power systems are behaving. The non-modular wiring provides you with a pair of 6+2 PCIe connectors and a half dozen SATA connectors in addition to the usual motherboard power connections.
You can check out the full PR below the specifications listed here. Both models will come with a 5 year warranty and cost $399 and $499 respectively.
October 26, 2016 – Taipei, Taiwan – FSP, the performance power specialist, is pleased to announce a new 500W addition to its Twins series redundant Power Supplies, with a 700W version coming soon. Fitting most ATX tower chassis, these PSUs offer consumers a reliable solution for home mail, web, or email servers without needing to jump up to more costly form factors.
Redundant Modules for Reliable 24/7 Operation
The Twins series houses two independent power modules, each with its own power adapter. Under normal conditions, the two modules share the energy load to maximize efficiency and stability. If one module fails, however, the other automatically takes over as a clean fail safe. Being hot-swappable, a failed module can be replaced while the system is running without any downtime.
Compatible with Standard ATX Cases
Users can mount the Twins in standard ATX cases without the need for a special bracket. Both ATX 12V and EPS 12V connectors are provided for maximum motherboard compatibility. Flat ribbon cables save space and installation hassle, perfect for cramped cases.
80 Plus Gold Efficiency and Server-Grade Reliability
Both Twins PSUs are 80 Plus Gold certified, offering up to 90% efficiency. Under constant operation, this drastically cuts down operating costs. Each power supply module features a dedicated dual ball-bearing fan, premium capacitors, and has over current protection, short circuit protection, over voltage protection, and fan failure protection. Reliability is further backed by a MTBF of 100,000 hours and a 5 year warranty.
LED Alarm Guard and Digital Control Software
The LED alarm guard alerts operators to problems in the system and simplifies problem diagnosis. If a power supply fails, an alarm will sound and an LED indicator will show which power supply needs to be replaced. Users can connect the Twins’ to a USB header for FSP’s Guardian software: a full suite of digital monitoring controls. Keep an eye on input, output, efficiency, and other metrics in real time, or review up to seven days of past data.
The FSP Twins Series is now available in 500W/700W versions at a MSRP of $399/499 USD, respectively.
