This document describes the FSP500-70RGHBB1 redundant power supply for servers. It is a 500W power supply in a PS2 form factor that does not require a front bracket, making it suitable for tower and 3/4U chassis. Each module can provide 500W of power and support hot swapping. If one module fails, the other can instantly take over without interrupting the server. The power supply has features like 80 Plus Gold efficiency, PMBus support, and protections. It is presented as a reliable and easy to install redundant power solution for home and enterprise servers.

1. First Ever Server Grand
PS2 Redundant
for
Home and Enterprise Server

2. PS2 Redundant Transformation in FSP
The Power Module Is Getting Smaller,
and the Form Factor Becomes
the Best Suitable for PC Compatible Chassis.
Generation I Generation II Generation III
Generation IV

3. This PS2 redundant (Twins 500W) is designed
for Standard ATX or PS2 Tower Chassis, no
front end bracket needed. You can use in a
Home server, Enterprise server, IT shop and
System integrators.
During normal operation, the modules share
the load for optimum efficiency. If one fails,
the other can instantly take over the load
without interrupting the computing. Each
module comes with a line to a wall socket so
they can be on separate fuses if there is access
to different plugs. This is the best power
supply for future IoT integrated intelligent
house.

8. Q1: What are the major differences among FSP500-70RGHBB1 and
other Mini Redundant Power Supply?
Ans.: FSP500-70RGHBB1 offers much easy installation without bracket at rear window (details
please refer to Q2), high efficiency 80+ Gold, PMBus 1.2 for digital power management and also price-
competitive .
Q2: Why FSP500-70RGHBB1 is the best solution of redundant PSU
for Tower Server and 3/4U Server?
Ans.: When you install Redundant Power Supply on Tower Server or 3/4U Server, FSP500-70RGHBB1
is absolutely an ideal solution - you do not need bother the trouble of the bracket at rear window,
because FSP500-70RGHBB1 supports PS2 form factor with 4* standard
mounting holes like Single PS2 PSU. Meanwhile, you could perform the
hot swap function by pulling out the module without any interference.
If you were SI or PC/IPC distributor who might need bundle Single PS2
Power for Tower and 3/4U Servers as standard configuration due to the
cost concern and offer an option with redundant PSU, then
FSP500-70RGHBB1 is an excellent choice.

9. Q3: Is there any compatible model of FSP500-70RGHBB1 with + / -
wattages?
Ans.: Yes. In addition to FSP500-70RGHBB1, FSP offers FSP400-70RGHBB1 now and plans to release
600W/700W version at Q1 2016. In other words, FSP offers wide range of 400W ~ 700W to fulfill the
different market requirement.
Q4: Which Chassis are compatible with FSP500-70RGHBB1?
Ans.: Most of Tower Servers and 4U Rack Server Chassis are compatible with FSP500-70RGHBB1, for
example, Chenbro SR105/SR107/SR112, Chenbro RM413/RM423. Chieftec Tower Server and 3/4U
Rack Server Chassis.
