We’ve never tested products from HIPRO before, but this is actually the PSU brand of Chicony, which is a much better known name. Chicony claims that all of its products are manufactured on its own facilities.

The HIPRO HP-D5201AW comes from the entry-level K1 series which even lacks basic 80 PLUS certification. The series ranges from 460 to 630 watts. Although not particularly new, it is still widely available in shops.

The HIPRO HP-D5201AW is shipped in a medium-sized glossy cardboard box. The design is gaudy with multicolored lines of text against a blue background and a picture of a submarine (we really wonder what relation might exist between this ATX power supply and the U-Boot-Klasse XXI).

The packaging is unified for not one but two PSU series: K1 (our model comes from it) and K2 (it has a somewhat shorter range of wattage ratings and features basic 80 PLUS certification).

Besides the PSU, the box only contains a mains cord.

Exterior Design

The HP-D5201AW seems to have a regular design with a 120mm fan behind a wire grid, thick panels of the case and black paint.

Besides an On/Off switch, there is a LED indicator on the back panel that shows you if the PSU is turned on.

The unusual thing about this PSU design is that the detachable part of the case includes the front, top and bottom panels instead of top and side ones, as usual. 

Circuit Design

The unusual design of the case allows us to have a look at the reverse side of the main PCB.

We can note quite a number of neatly soldered small components here.

The HP-D5201AW is a typical inexpensive PSU with active PFC and no dedicated voltage regulation.

The PWM & PFC controller and the supervisor chip reside on a daughter card near the front panel of the case.

A popular CM6800G chip is responsible for PWM and PFC.

A less popular CP006WD chip is responsible for monitoring and protection.

Judging by the PCB marking, HIPRO K1 and K2 series products all share the same PCB. We can also note the unusually small size of the SamXon capacitors at the input:

The PSU employs electrolytic capacitors from Ltec at the output. They are not considered high-quality components.

Cables and Connectors

The HIPRO HP-D5201AW is equipped with the following cables and connectors:

  • One mainboard cable with a 20+4-pin connector (41 cm)
  • One CPU cable with a 4+4-pin connector (56 cm)
  • One graphics card cable with one 6-pin connector (41 cm)
  • One cable with three PATA power connectors and a floppy-drive plug (41+12+12+12 cm)
  • Two cables with one SATA, one PATA and one more SATA power connector (40+12+12 cm)

Every cable is sleeved up to the first connector. Although the cables aren’t very long, the CPU one should be long enough for system cases with a bottom PSU bay.

The PSU only offers four SATA power connectors on two cables. That’s too few for today’s PC configurations.


The HP-D5201AW specs are typical of entry-level PSUs. The load capacity of the +12V rail is only about 80% of the PSU’s total output power. The latter is but slightly lower than the combined load capacities of all of the power rails.

The PSU comes from the K1 series and lacks any official 80 PLUS certification which is only available with the K2 series.
