Super Flower Leadex Titanium 1000W PSU Review

Super Flower was one of the first companies to release an 80 Plus Titanium-rated PSU. Following the ultra-high-capacity SF-1600F14H unit, the company released two more Titanium PSUs, one of which we're evaluating today.

Ripple Measurements

To learn how we measure ripple, please click here.

The following table includes the ripple levels we measured on the SF-1000F14HT's rails. The limits, according to the ATX specification, are 120mV (+12V) and 50mV (5V, 3.3V and 5VSB).

Ripple suppression is good on every rail except 3.3V, where we measured a 36mV worst-case scenario. There were probably sacrifices made there to allow for higher efficiency. The 80 Plus Titanium requirements are difficult to achieve, and a non-digital platform has to use every trick in the book to achieve them.

Ripple Oscilloscope Screenshots

The following oscilloscope screenshots illustrate the AC ripple and noise registered on the main rails (+12V, 5V, 3.3V and 5VSB). The bigger the fluctuations on the screen, the bigger the ripple and noise. We set 0.01V/Div (each vertical division/box equals 0.01V) as the standard for all measurements.
