Efficiency rating

Efficiency is a key indicator of the technical quality of a power supply, as it not only describes the energy loss, but also significantly influences the thermal load and therefore the fan noise. In the measurements, the Vero L6 shows a stable performance typical of its price class, which in practice leads to unobtrusive and functional operation.

Efficiency at 230 V input voltage

The efficiency curve over the load initially shows a steep increase, which exceeds the 80 percent mark even at low loads of around 40 to 60 watts. From around 150 watts, the power supply unit reaches its optimum efficiency of just under 89 percent and maintains this over a wide range up to a load of around 400 watts. After that, the efficiency drops slightly, but remains above 85 percent up to full load, which is a good result for a double-forward DC-DC platform in the lower price segment.

The color-coded 2D efficiency map across all load combinations confirms this impression. The majority of practical operating scenarios are in the green range (85-90%), which means consistently good energy utilization for typical gaming and office systems. Only in very low load ranges – for example when modern systems are idling – does the efficiency drop significantly, which is due to technical reasons for this power supply class and is practically irrelevant.

Behavior at high ambient temperatures

The efficiency measurement at elevated ambient temperatures of 37 to 47 °C shows the unavoidable thermal influence on the platform. The curve is visibly below the value at normal temperatures, but remains within the range of what can be expected from a price-conscious power supply unit. The optimum efficiency drops to around 85 percent when exposed to heat, which is an important estimate for realistic temperatures in summer or in tight enclosures. The drop is continuous, but the platform remains stable and operates without noticeable distortions across the entire load range.

Efficiency of the 5VSB rail

The 5VSB rail is responsible for the standby and sleep mode of a PC and is therefore directly relevant for compliance with the ErP specifications. The efficiency measurement curve shows a typical progression: very low efficiency in the minimum range, a rapid increase up to around 2-3 W load and then a largely stable efficiency of just under 78 percent.

The individual measurements also confirm this curve. Even at 0.045 A, the efficiency is just under 49%, but rises quickly and reaches its best values of around 78% between 1 and 1.5 amps. These values are perfectly acceptable for a budget power supply unit and show that the standby supply works efficiently enough to reliably meet the regulatory requirements.

Power consumption in idle mode

The power consumption in idle mode is a decisive factor for the energy efficiency of a power supply unit outside of actual operation. The values measured here show very clearly that the Endorfy Vero L6 750 Watt has been carefully optimized in this discipline and clearly meets the applicable European specifications. The real power consumption when switched off is only 0.144 watts on average. The lowest measured value is 0.089 watts and the highest is 0.194 watts. All values are therefore well below the permissible limit of the ErP Lot 6 directive, which sets a maximum consumption of 0.50 watts for complete systems. The power supply unit therefore actively contributes to ensuring that a PC remains energy-efficient even when switched off and does not cause unnecessary standby losses in the long term.

The other mains parameters underpin the stability of this measurement behavior. The mains voltage remained constant during the measurements in the range between 227.70 and 232.30 volts, with a stable frequency close to 50 Hz. The distortion factor of the input voltage is minimal with values around 0.14 percent and proves that the measurement conditions were clean and representative. The extremely low power factor of 0.007 in idle mode is striking. This value is typical for standby mode, as only individual components of the 5VSB rail are active and the energy flow is minimal. Although the power supply unit appears to consume a relatively high apparent power of around 22 volt-amperes, in reality only a negligible real current of 0.144 watts on average flows. This shows that the standby circuit works efficiently and only maintains the necessary basic operation.

The measurement thus confirms that the Vero L6 is excellently tuned in standby mode and not only complies with the regulatory requirements, but falls well below them. For users, this means that the PC behaves extremely frugally when switched off and the power supply unit is one of the more efficient representatives of its class in this respect.

ErP Lot 6 / Lot 3 – specifications and classification

Compliance with the ErP Lot 6 directive, which defines strict specifications for standby consumption, is crucial for the European market. Specifically, a complete system must not consume more than 0.5 watts when switched off. With a measured standby power consumption of just 0.1441 watts, the Vero L6 is well below this limit, which shows that both the design of the 5VSB rail and the internal loss-minimizing logic have been properly implemented. This is particularly pleasing in view of the price-oriented positioning of the power supply unit, as many inexpensive models have deficits in the standby range in particular. The Vero L6 not only meets the legal requirements here, but also operates consistently within a range that also minimizes energy losses in the long term.

Overall conclusion on efficiency

The efficiency performance of the Vero L6 impresses with its good suitability for everyday use. It works solidly and stably in the relevant load ranges, with both the 230 volt main measurement and the 5VSB results providing a technically coherent overall picture. The platform achieves its peak efficiency in a practical range, reacts to high temperatures in a controlled manner and meets the regulatory consumption specifications by a clear margin. Despite its price, the power supply is therefore energy-efficient enough to be a sensible choice for common PC configurations.
