Fortron/FSP Zen 400
The Zen 400 from Fortron, with its output of 400 watts, stands out immediately thanks to its blue color. Compared to its 300 watt predecessor, the first thing you notice is a large aluminum cooling element on the underside of the unit, which is reflected in its considerably higher weight.
There is a single 6-pin connection for graphics cards. The ATX connection corresponds to the ATX12V 2.2 standard; it has 24 pins and can be split to accommodate older motherboards.
The unit’s connections are no longer up-to-date. It only has four SATA connections, yet these are becoming more and more important. Oddly, there are still six of the 4-pin Molex connections used by older drives. There are also two floppy connections on the power supply, though these can be used for fan controllers. The +12V CPU connection is only available as 4-pin version, which can lead to problems with some boards that require an 8-pin connection.
The length of the connection cables also leaves a lot to be desired: only 16” (40 cm) to the ATX connection. This may be too short for larger cases, and as a result, it may not be possible to route the cables as neatly as one would like.
