At the face of the box is a photo of the PSU, along with the model name, capacity description, and several badges depicting the unit's efficiency, Japanese capacitors, DC-DC converters for the minor rails, semi-passive operation, and ten-year warranty. FSP also has an icon for the dual EPS (CPU) connectors of this PSU. On the back, the most important features of this product are covered.


Protection inside the box is good since a foam spacer surrounds the PSU. The bundle includes the user manual, fixing bolts, and the SFX to ATX adapter bracket.



The cooling fan is not centered. This tends to be a trend with small form factor PSUs. At the front, we have the on/off switch and AC inlet. There is no switch to toggle off the unit's semi-passive operation, which is a shame.


On the two sides, we find stickers with the model description. The power specifications label is on the bottom of the unit.


The modular panel has eight sockets, two for the 24-pin ATX connector, two for the peripheral cables, and three for the EPS and PCIe cables. Both EPS and all four PCIe connectors are available simultaneously since all three cables have two connectors.


The fan grille does not restrict airflow, which is a highly welcome feature in a high-capacity SFX power supply. Moreover, the unit's finish is matte, so it is both fingerprint proof and scratch-resistant.

The cables are pretty long for an SFX PSU, which holds especially true for the ATX and EPS cables. Moreover, they are flat and "stealth," which means their gauges are black as well. There are no in-cable caps, which is ideal for most users, and the number of EPS and PCIe connectors is adequate.

I'm not too fond of the fact that both EPS connectors draw power from the same socket. While the only way to provide two of these connectors because of the small dimensions of the modular panel and low number of sockets, it is not safe if used with a power-hungry CPU.


I would like to see more SATA and 4-pin Molex connectors. Lastly, there is no need for the FDD connector. They should provide an additional 4-pin Molex connector instead and include an FDD adapter for the few who need it.
