A Detailed Look
The FSP Twins 500W redundant power supply enclosure/frame is painted satin black and measures 190mm (7.4””) deep. The power supply comes with a basic assortment of flat ribbon-style fixed cables (see specs section for details).
Removing the cover exposes the two modular power supplies. The modules slide into the main chassis/frame from the rear and plug into card-edge-connectors at the front. A mechanical latch holds the modules in place.
Each modular power supply is cooled with a 40mm fan mounted on the front (Protechnic Electric MGT4012ZB-W28) rated at 0.49A at 12 VDC and use double ball bearings, which is good as these little fans can easily spin in excess of 10,000 rpm. Unfortunately, these small diameter fans are the common choice for use in server-style power supplies because of space constraints. The obvious down side is the noise they generate.
Do most redundant server PSUs
Do most redundant server PSUs operate in this fashion or keep one on standby?
Most of them can be
Most of them can be configured to act either as a 1+1 (failover) or a 2+0 (both live).
If this cant be configured to
If this cant be configured to be 1+1 then its kind of pointless.
I currently use a high end Seasonic with a APC UPS for reliability.

Redundancy is exactly the point of this. I will most likely be buying 15 of them. Have been waiting for something like this forever!
When your production machines are 10,000$ per hour per line, having a power supply go out can cost thousands.
So I’ve known that redundant
So I’ve known that redundant PSU’s have been standard in rack-mount cases for a long time, so what’s the use-case for using these in standard ATX machines?
Rendering boxes, or other such machines?
I just legitimately don’t know.
Anytime you have a PC running
Anytime you have a PC running a mission-critical app or controlling high-value process equipment, you want to maximize up time by minimizing any potential hardware failures, like the PSU. I used to work in Bio-tech R&D and we frequently used redundant PSUs along with large UPSs on mass spec instruments and PCs running High Throughput Screening robotic systems. Any down time could cost thousands of dollars per hour.
