FSP Group MEGA TI 1650W Power Supply - LABS Test Report

Duration: 03:42

Due to the dual wattage rating of this power supply, we conducted 115V testing with a maximum output wattage of 1500W while the 230V testing was conducted with the full output wattage of 1650W. The 115V sweep tests have been omitted from the video to prevent confusion and inaccurate comparisons. See the LTT Labs website for more testing details.

The FSP Group MEGA TI 1650W is a monstrous ATX 3.1 power supply that pushes the boundaries of what your wall socket can handle. To hit its full 1650W output, it needs at least 200 volts of input - anything less and you're capped at 1500W. It’s an incredibly capable unit, and it certainly looks the part, but you'll pay a premium for the privilege. The MSRP is a steep US$459.99, though it appears to have increased to an even steeper US$549.99. Price and availability may vary.

Due to the dual wattage rating of this power supply, we conducted 115V testing with a maximum output wattage of 1500W while the 230V testing was conducted with an output wattage of 1650W. Only the 1650W results will be shown on this product page so that the results can be easily compared.

The first unit we tested failed during testing of the 12V rail OCP limit(with 115V input), the second unit tested passed all protections testing but we refrained from conducting the 12V rail OCP(with 115V input) test. We have confirmed with FSP Group that there is no hardware/firmware mechanism to enforce the 1500W limit when supplied with 115V input power.

Theoretically, with an input connection(circuit breaker, wiring, wall socket) that can deliver over 15A, the power supply can deliver 1650W with 115V input. This increased current generates more heat in the internal components of the power supply, meaning that an upgraded cooling solution would be required. This is absolutely not recommended by LTTLabs or FSP Group.
