Test results

We have checked the PSU against the stated specifications, using the power testbed PSU-test 950W (in Russian) and the digital wattmeter TrueRMS Metrix PX-110 (in Russian).

The primary test is to obtain a cross-load characteristic and draw it on a half-plane limited by the 3.3&5V line power on the Y-axis and the maximum 12V line power on the X-axis. Each point of the graph is colored according to its deviation from the nominal value:

  • Rich green - 1% (excellent);
  • Light green - 2% (very good);
  • Yellow - 3% (good);
  • Orange - 4% (satisfactory);
  • Red - 5% (bad, but inbound);
  • Black - over 5% (poor).

The test results indicate that PSU operation is excellent. Note that during tests we stumbled upon PSU instability at low load on the 12V line. To conduct our tests we had to load the 12V line with the steady load of 50W.

The efficiency is the primary characteristic that indicates energy efficiency of a PSU. Its value indicates how many percent of energy consumed from the power supply network will be output by a PSU after conversion. We assume that the efficiency of 85% and higher is excellent, 80-85% is good, 75-80% is satisfactory, below 75% is poor.

The manufacturer stated the efficiency of this PSU as 85%. We conducted tests for efficiency and power factor in the load range of 50 to 800W.

The test results indicate very high efficiency at 200W to 800W output power. The maximum efficiency of 86% is achieved at the load of 500W. From 150W to the nominal wattage, the efficiency was at least 82%, power factor being above 88%. We consider these values very good.

After an hour of operation at the maximum power and the ambient temperature of 27°C, the temperature of the hottest point of the PSU enclosure was 37°C and the air exit temperature reached 51°C.

Like we had suspected, the cooling system turned out to be very ineffective. When you actually install this PSU into a PC enclosure, temperatures will naturally be higher.
