Ripple Measurements

To learn how we measure ripple, please click here.

The following table includes the ripple levels we measured on the TPI-1200F2FDP's rails. The limits, according to the ATX specification, are 120mV (+12V) and 50mV (5V, 3.3V and 5VSB).

Thermaltake's ripple suppression is excellent! CWT worked wonders in this discipline, approaching Super Flower's performance. As digital circuits become more prevalent, we should see more amazing ripple results like these.

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/noise. We set 0.01 V/Div (each vertical division/box equals 0.01V) as the standard for all measurements.

    Your videos don't work I get the error "cannot load m3u8 crossdomain access denied (2048)"

    Everyone reviews heavily on capacitor quality but how is cap quality determined ? Is it published specs or just reputation / country of origin ?

    The bad cap crisis was over ten years ago are all those makers
    still putting out bad or inconsistent products ?

    The videos work fine for me.

    Caps: Mostly based on experience and the RMA data that I have access to. The quality of the electrolyte is what matters the most.

    CapXon & Su'scon caps? more chinese junk for a premium price. I would never buy anything from Thermalsewer
