You get a vast number of cables and connectors with this unit, which can easily handle the 1650W max power output. All cables are long and it is nice to see dedicated PCIe cables, hosting one connector each. Moreover, the distance between peripheral connectors is adequate at 150mm.

High Power provides this platform, and although it doesn’t use cutting-edge technology, it has high build quality and uses quality components. We usually meet full-bridge topologies in high capacity PSUs, but the DA1650-G uses a half-bridge topology. They went with an interleaved PFC, at least. On the secondary side, the filtering capacitors are of good quality. We also spotted an MCU on the secondary side, for which we don’t have any information on what it exactly does.

The transient filter has all the necessary components to filter EMI effectively. There is also an MOV to protect against voltage surges. Inrush current protection is handled by an NTC thermistor, which is supported by a bypass relay.

The pair of bridge rectifiers can handle up to 100A of current! This is insanely high, even for a 1650W PSU.

The interleaved PFC offers higher efficiency levels and minimizes input/output current ripple. The bulk caps’ capacity is low, so the PSU cannot reach 17ms hold-up time, as the ATX spec requires. These caps cost a lot, so larger capacity ones would notably affect the product’s price.

Infineon provides the two main switching FETs, and they are powerful, with low Rds (on), which plays a huge role in energy losses. An LLC resonant converter is also utilized for higher efficiency. The resonant controller is a Champion CM6901X IC.

Ten Toshiba FETs regulate the 12V rail. All are installed on the solder side of the main PCB. The 12V rail also feeds two DC-DC converters, which generate the minor rails.

The modular board hosts many polymer caps, for lower ripple on all rails.

We don’t have any complaints to make when it comes to soldering quality. High Power did a good job in this section.

The 5VSB circuit uses an SBR and two FETs along with an Excelliance MOS PWM controller.
