Overall Performance

Here is the link to read more about this performance algorithm.

The overall performance is decent, with the difference from other high-end 1300W units not being that high. If ripple suppression and transient response were better, the darkFlash unit would score way better in these charts.

  1. Is it just me or could the PSU have performed significantly better in ripple suppression and transient response if they hadn’t gone with such an extremely low amount of secondary caps on the secondary side?
    I count 27 caps or which many are fairly small. Other manufacturers like Seasonic are liable to use over 50 caps in that power class.

    Yes the form factor is small but they definitely had space for more caps on the breakout board. They cheaped out, which is a pity.

  2. UPMOST? XD
    It’s nice to see that there is so much optimism and imagination around.
    This should lead to improvement.
