The Andyson N500 Titanium PSU - External Appearance

If not for the side sticker indicating its Titanium status, the N500 could be easily mistaken for a run of the mill 500W PSU. It is very simple, without any important aesthetic enhancements, save from the sticker on the right side of the chassis. The chassis is sprayed with a satin black paint.


Another sticker is covering the left side of the chassis, with a table indicating the electrical specifications of the unit printed on it. Paying particularly close attention to asthetics, Andyson actually installed the N500 Titanium sticker upside-down so that when installed in a windowed left side panel, the visible sticker always appears right-side-up regardless of its orientation.


The rear of the PSU is of no interest, with a typical AC cable receptacle and on/off switch. A small metallic plate indicates that this is a "full range" model, i.e. it can operate on any consumer's electrical grid on the planet.

Only four connectors for the modular cables can be seen at the front side of the unit. The native fixed cables of the PSU, the ATX 24-pin and the CPU 12V 4+4-pin cables, exit from a hole near the edge of the unit. Just like the modular cables, these are very basic, with black sleeving covering color-coded wires. It is also interesting to note that the sleeving of the 24-pin cable was a little damaged near the hole, despite Andyson having a plastic protection ring installed.

The Andyson N500 Titanium PSU - Internal Design

Andyson rebranded the fan of the N500 Titanium and thus we could not safely identify its model. It is a 135 mm fan with a maximum speed of 1600 RPM and a power draw of 0.08 Amperes. It also appears to have a sleeve/fluid type bearing.

Andyson designs and creates their own PSUs, therefore there is no other OEM behind the N500 Titanium. There are some strange things to notice about the layout of this PSU, with the strangest of them all being its simplicity. The design is based on a half-bridge inversion stage with resonant conversion, which is good but atypically basic for such a high efficiency product.

Another strange part comes right after the filtering stage; there are not one, but two rectifying bridges. While the use of a standard bridge in a Titanium-grade unit is peculiar to begin with, the use of two bridges in a 500W unit is even stranger. With the current rating these bridges have, they could easily be used for a design with three times the power output. The bridges are attached on the heatsink with the APFC active components, one transistor and one diode.

The third peculiar thing about this unit is the presence of two Nippon Chemi-Con APFC capacitors, rated at 420V/270μF each. They are very high quality capacitors but their combined capacitance is far too high for a 500W PSU. Most of the secondary side capacitors are supplied by Nippon Chemi-Con as well, but we also spotted Toshin Kogyo (TK) products among them. TK may not be a very popular brand with computer PSU manufacturers but it is a reputable Japanese company. The polymer capacitors are all supplied by Teapo.

On the secondary side, the heatsink for the secondary converters surrounds the transformer's block. The transistors are not mounted directly onto the heatsink but beneath the main PCB, with a thermal pad transferring part of the heat to the chassis as well. Two small DC to DC conversion circuits generate the 3.3V and 5V voltage lines.

Finally, the assembly quality of the PSU is very good. The soldering job is excellent and everything seems well-secured. However, there is virtually no silicon glue in the N500 Titanium PSU. Manufacturers frequently use glue to mechanically secure components and prevent damage during transportation. This does not mean that the N500 Titanium can be easily damaged, but some glue on larger components would not hurt.

    While well within spec, the ripple suppression on this unit is not very impressive.
    Using numbers from the EVGA Supernova G2 550W easily beats this unit on load regulation and ripple suppression, for $20 less.

    Saying that, the Andyson N700 Titanium tested got load regulation and ripple suppression numbers which equaled or bested the EVGA Supernova.

    You really shouldn't compare reviews from one reviewer to another when the results are this close. Different test equipment and testing methodology will result in slightly different findings.

    You said the magic word "slightly" so what he is talking about is most probably true.

    Season are built like god damned German tankers. Best money I ever spent, probably my longest lasting PC part I've ever purchased.

    agreed. even with its 7 year warranty, i expect to keep my 750wt Seasonic platinum for atleast 15-20 years. What PC desktop part lasts that long???

    And how loud is that EVGA unit according to techpowerup's review? That's the thing people so often neglect to mention when bragging about those units.
  • Oxford Guy - Sunday, October 11, 2015 - link

    I haven't looked at the review of the 550W unit but I remember 48 dB for the 750W unit at 600 watts, and 48 dB for just 300 watts and above with the 850W unit.
  • Oxford Guy - Sunday, October 11, 2015 - link

    Actually more like 350 watts for the 850W unit. But, still... that's bad acoustic performance.

    So, 85% efficiency when my machine is idling and consuming 44W? I dont know, that doesnt seem very good.
