GoKawiilFSP's in-house Mega GM 1200W PSU tests near Platinum despite Gold rating
Tom's Hardware reviewed FSP's self-designed Mega GM 1200W power supply, finding efficiency that performs like Platinum tier even though it's only Gold-certified, top-tier Cybenetics acoustic scores, and all-Japanese capacitors. The unit ships with native 600W 12V-2x6 output, a compact chassis, a robust protection suite, and a ten-year warranty, priced around $229.
GoKawiil's interpretation of the reporting above, not reported fact.
FSP is a major OEM that builds power supplies for many other brands, so a strong in-house design signals the manufacturing capability behind products sold under other labels. For buyers, it also suggests that certification badges like Gold or Platinum don't always capture a unit's real-world performance, making independent testing more useful than label-shopping.
- Efficiency performs at near-Platinum levels despite only a Gold certification
- Uses all-Japanese capacitors and earns top acoustic marks from Cybenetics
- Priced near $229 with a ten-year warranty and native 600W 12V-2x6 support
