This power supply has seven Schottky rectifiers on its secondary and all are the same model: MBRP3045N, which can deliver up to 30 A (15 A per internal diode at 100º C).

The maximum theoretical current each line can deliver is given by the formula I / (1 - D), where D is the duty cycle used and I is the maximum current supported by the rectifying diode. Just as an exercise, we can assume a typical duty cycle of 30%.

The +12 V output is produced by three of those rectifiers, so we have a maximum theoretical current of 64 A (15 A x 3 / 0.70), what equals to 771 W.

The +5 V output is produced by two of those rectifiers, giving us a maximum theoretical current of 43 A (15 A x 2 / 0.70), which equals to 214 W.

The +3.3 V output is produced by the other two available rectifiers, giving us a maximum theoretical power of 141 W.

As you can see all outputs are highly overspec’ed, which is always good to see.

This power supply uses a PS229 monitoring integrated circuit, but specific information about it isn’t available on the manufacturer’s website.

The electrolytic capacitors from the secondary are also from Teapo.
