Introduction

FSP Logo




FSP stands out not just as a retail brand, but as one of the true heavyweights of the industry. As a major OEM, FSP actually designs and builds the internal platforms for many of the most recognisable names in PC hardware such as be quiet!, EVGA, Thermaltake and NZXT. Because of their experience in industrial, server, and enterprise power delivery, FSP's consumer units routinely inherit over-engineered server-grade reliability. The brand has quietly built a reputation for delivering rock-solid stability and longevity, making them a go-to choice for enthusiast builders who prioritise proven engineering over flashy marketing.

The new FSP MEGA PM 1200 is built to the latest ATX 3.1 and PCIe 5.1 standards. Beyond its premium 80 Plus Platinum and Cybenetics Platinum efficiency ratings, the MEGA PM 1200 comes with FSP's "Off-Wet, Off-Dust, and Off-Stain" conformal coating, an industrial feature designed to protect internal components from harsh environmental factors like high humidity. Packing all of this, along with high-quality 105°C Japanese capacitors and a quiet 135 mm semi-fanless Fluid Dynamic Bearing fan, into a surprisingly compact 150 mm chassis makes the MEGA PM 1200 an appealing candidate for a high-end build.
