By the way, there is a card with two thermo-resistors on the left of the chokes. They measure the temperature of the heatsink.
Other chokes, located far from the heatsinks, are cooled in a more original way. They are equipped with chunks of aluminum that ensure thermal contact between a choke and the cover of the PSU case.
Among other things, I can note the use of only 105°C capacitors in the Phantom 500. In ordinary power supplies such capacitors are only employed in the highly loaded output circuits, and cheaper 85°C capacitors are installed elsewhere, but for a fanless model the use of 105°C capacitors is a must everywhere because they get heated up by the surrounding heatsinks due to the lack of airflow.
There’s a plastic cover above the fan on the rear panel of the PSU case. It must be removed if you want to get inside the PSU.
Having removed the decorative cover that is fastened on latches, I found another, this time metallic, PSU panel and an 80x80x15fan underneath. A small portion of the airflow from the fan goes aside the PSU’s internals through the ribs in its heat-spreading top panel.
This is the Xinruilian RDM8015B model.
There is a tiny 3-position switch next to the fan. The PSU manual says this switch controls the cooling efficiency, giving you the opportunity to choose between quiet and cool.
The specification of the Phantom 500 is somewhere in between versions 1.2 and 2.0 of the ATX12V standard. On one hand, its load current on the +5V rail can be as high as 30A, but the +12V rail isn’t much worse – its load current is up to 35A.
The PSU is equipped with the following cables and connectors:
- Mainboard cable with a 20+4 connector (50cm long)
- CPU cable with 8- and 4-pin connectors (50cm from the PSU to the first plug and 15cm more to the second plug)
- Two graphics card cables with 6-pin connectors (48cm each)
- One cable with two Molex connectors and one floppy mini-plug (49cm+15cm+15cm)
- One cable with three Molex connectors and one floppy mini-plug (49cm from the PSU to the first plug and then 15cm more to each next plug)
- Two cables with two SATA power connectors on each (52cm+14cm)
