Review on FSP Swappable Redundant Guardian FSP500 50RAB by Ben Rodriguez

The unit works as advertised and I can change modules without shutting down the system. I ordered a replacement Module 520 and received a Module 720. The packaging was correct but the label on the outside of the box was incorrect. I took this opportunity to try the 720 module in the 520 block and it worked correctly. The 720 module had higher fan speeds and lower wattage, but I found similar differences between the two 520 modules: I wish it was "modular" so there wasn't a bunch of cables crammed into the case. It's also quite noisy when you first turn it on, but it quickly becomes noticeably quieter.
