PSU Aerocool Templarius Imperator 750 Review

At turn of the previous year Aerocool launched a new series of PSUs, united within a single series Templarius Imperator. The series involves a line of models ranging 550W-1500W power index. A part of those units are known to correspond to 80Plus Silver standards, while the other part – to 80Plus Bronze standards. Model Templarius Imperator 750 complies with 80Plus Silver requirements, due to the claimed efficiency of 88%. This feature implies that this PSU might appear to be helpful in the assembling of quite powerful PC platforms.

Delivery Set and Exterior Design

Aerocool Templarius Imperator is delivered in a white cardbox which inscriptions distinctly make out about the unit’s gaming predestination. Its internal contents involve the unit itself and a set of modular cables. The model is developed in white color design and is housed in a steel case; it features 170x150x85 mm dimensions. Modular sockets are located on the rear facet. The attached label contains basic information about PSU facilities. Hence, it claims that +12V rail endures a load of 696W that makes up 95% out of the entire unit’s power. The maximal admissible current at +3.3V and +5V rails makes up 24A. It might serve a sign of the implementation of a separable voltage regulation scheme within the layout.

Framework Peculiarities

Internal framework of Templarius Imperator 750 is based on a platform developed by Andyson that is truly characterized by a separable voltage regulation template on the main power rails. The input filter is represented by several capacitors and a single throttle; there is also a heatsink mounted on a diode bridge. Under the heatsink in the high-voltage PSU block one can find a soldered APFC throttle, accompanied by two parallel capacitors estimated for 390 and 82 microfarad under 420V potential.

The heatsink itself accommodates four MOSFETs (two SPP24N60C3 and two SPP21N50C3) and a high-voltage diode C3D10060. The +5V rail voltage decoder is based on STR-A6069H chip and involves SBL1060CTW power supply rectifier. The heatsink integrated at the low-voltage section dissipates heat produced by three FB3206G MOSFETs. Next to it Aerocool installed a pair of DC-DC converters housed on separate circuit boards. They are based on APW7073 chip and generate voltage for +5V and +3.3V rails. The +12V rail involves three electrolytes of 3300 microfarad 16V, while +5V and +3.3V rails embrace a single electrolyte of 2200 microfarad 10V. PS223A chip takes responsibility of monitoring the output voltages.

Finally, cooling process is organized by means of an integrated fan DFS132512H (Young Lin Tech) of 135 mm dimensional type. It is equipped with four white LED lights.

Testing

Testing results demonstrate the stability of +12V rail operation. Thus, voltage index on conditions without loading fluctuates within the measures of 12.31V, while on loading conditions the index drops to 11.91V. Such showings are thought to be within normal limits. Voltage index on +5V rail drops from 5.13V to 5V and on +3.3V rail it diverges within ±3% from the norm.

The heatsink in a low-voltage section warms up to 70 degrees on the maximal loading. This is considered to be a satisfactory result for such type of PSU. The implemented fan starts gaining its rotational speed once the thermal sensor (fixed on the heatsink) shows +40 degrees. Still, the unit can’t boast perfect noise characteristics, since the development of speed results in the rise of noise level that is clearly audible within a few meters.
