The FSP MEGA GM Series adopts a fan grille design similar to the FSP MEGA TI Series, featuring a silver-coloured vent plate paired with a two-piece shroud construction, reinforcing its premium design approach.


The rear of the FSP MEGA GM has two switches – the switch and the eco semi-fanless mode switch which is turned off by default.


The visible side of the PSU features minimal branding, limited to a small print of the brand and series name, along with a discreet circular sticker that serves as the warranty seal.


The top panel features a large label containing essential information about the PSU, including output specifications, certifications, the serial number, and other regulatory details.


The MEGA GM Series features a fully modular cable design. While some users may have reservations about the connector layout, particularly the positioning of the locking mechanism, FSP’s implementation on the MEGA GM places the clips on the more accessible side of the PSU, making cable installation and removal straightforward.


In scenarios where troubleshooting requires disconnecting cables from the PSU, this design proves particularly practical. The connectors remain easily accessible, unlike some layouts where the locking tabs are positioned along a single edge— such as the COUGAR GLE Series PSUs— or placed in close proximity to one another, as seen on the be quiet! Pure Power 13M, which can make cable removal more cumbersome.


FSP also implements this modular cable layout on the FSP VITA GM, which we have previously reviewed. This consistency across product lines highlights FSP’s experience in PSU design, with the connector layout carefully considered to balance accessibility and ease of use, particularly for cable management and maintenance.
