Annual horizontal evaluation of 600W power supply: 25% online celebrity rollover

one   Power Supply Review the background

RTX The 40 series graphics cards have been fully distributed, which is good news for gamers. In addition to improving game performance, the RTX 40 series graphics card also greatly reduces power consumption. The RTX 4070 graphics card platform can meet the demand with 600W power supply.

Purpose and selection of power supply horizontal evaluation:

When choosing products, many players will struggle. The power supply of 1 yuan/W is still too expensive. Is it reliable to buy a 600W power supply of 0.5 yuan/W, that is, 300 yuan? In order to have a more comprehensive and in-depth understanding of the power supply market for mainstream platforms and provide practical guidance for players to purchase, we selected 600W power supply between 200-300 yuan in this year's power supply horizontal review, and finally selected 12 products, as shown below (listed according to the Chinese name of the brand).

The 600W power supply is positioned as a mainstream platform. Although the power supply is not expensive, the hardware price can reach as much as 7000 yuan, and the power supply stability related to hardware safety is also worthy of attention.

In order to ensure the fairness and impartiality of the horizontal evaluation, all the 12 power supplies in this horizontal evaluation were purchased from e-commerce, and the test products were not accepted, so as to ensure that the test results of each product were the same as the products purchased by consumers.

We contacted Guangdong Zhongyuan R&D Laboratory for the horizontal evaluation of power supply, and a third-party laboratory was responsible for data collection. The test instrument used in the horizontal evaluation was chroma8000, the test ambient temperature was 28-29 ℃, and the ambient humidity was 30-40% RH.

This horizontal evaluation of power supply will be based on Intel's power supply specification as the standard of whether the power supply is qualified. In addition, the conversion efficiency of the power supply will also be measured. By comparing the 80PLUS certification requirements, we will consider whether the power supply performance is false.

two Conversion efficiency test: 1 dummy label

The first test is the familiar conversion efficiency. The conversion efficiency of power supply is the ratio of output power and input power of power supply, that is, the utilization ratio of power supply to electric energy, The higher the conversion efficiency, the more power is saved 。

Among the 12 products in the horizontal evaluation of power supply, there are 5 products marked with 80PLUS certification, and 1 product fails to reach the nominal efficiency, which is Jinheda G6 (nominal copper brand, actual measurement fails to reach the white brand).

To facilitate the comparison of differences, we rank the power conversion efficiency under 50% load and 100% load separately. Among them, 50% load is a typical load, that is, 300W load, and 100% load is a full load, that is, 600W load.

From the test results, Xingu GP600W ATX 3.0 Black gold The conversion efficiency of the power supply is better under different loads. If you pay attention to the energy-saving performance of the power supply, it is recommended to choose this power supply first.

Before analyzing the following data, let's briefly introduce the purpose of the power supply output voltage+ 12V supplies power to CPU and graphics card, while+5V and+3.3V supply power to memory and hard disk. These two groups of data are directly related to the stability of hardware operation, which is also the focus of our consideration.

three Voltage deviation test: 1 rollover

Voltage deviation refers to the deviation amplitude between the output voltage of the power supply and the ideal value, The smaller the voltage deviation, the more stable the power supply voltage, that is, the smaller the voltage deviation, the better. Intel's ATX power supply specification is qualified if the voltage deviation is within 5%. This horizontal evaluation also uses 5% as the qualified line.

According to the measured data, only Jinhe Tian G6, one of the 12 power supplies in this horizontal evaluation, failed to pass, of which the+12V voltage deviation reached 11.6%, and the+5V voltage deviation reached 5.72%, both exceeding the limits of the power supply specification, and were judged as unqualified.

As for the performance of each product, the Xingu GP600W ATX 3.0 black gold version performs best, and the voltage deviation of each circuit is outstanding.

four Cross load test: 2 unqualified

After understanding the voltage deviation, the following cross loads will be easier to understand. This test simulates the voltage deviation under different scenarios, such as When the power supply is in standby environment, hang up download , full load of games, and Under different scenes such as 3D rendering, whether or not to provide stable voltage for hardware can be said that voltage deviation pays more attention to theoretical testing, while cross load is more suitable for actual use scenarios. So the deviation range of cross load is still the smaller the better.

The cross load voltage deviation is set according to the parameter nameplate of the power supply, and then the load settings under 7 different use environments are simulated, including standby environment, boot up moment, large games, 3D rendering, etc., switching different use environments, recording each output voltage, and comparing with the ideal voltage value, The maximum deviation is the cross load voltage deviation measured by us.

From the test results, two products failed in the cross load voltage deviation test, of which the+5V voltage deviation of GAMEMAX VP-600 reached 6.08%, exceeding the limit value, while the G6 of Jinheda turned off the output when the+12V was overloaded, unable to complete the cross load test, and withdrew from the subsequent test. The two products were judged as unqualified.

To sum up, Xingu GP600W ATX3.0, Hangjia JUMPER600 The output voltage of DK PREMIUM and the chief player is more stable. If you pay attention to the stability of the power supply voltage, it is recommended to choose these three products.

five Output ripple test: 2 unqualified

The output ripple refers to the clutter in the output current of the power supply, which can be considered as the purity of the current, The smaller the value of the output ripple, the purer the output current, and the smaller the impact on the hardware. Intel's ATX power specification is that the ripple of+12V is less than 120mV, and the ripple of+5V and+3.3V is less than 50mV. The same qualified line is used in this power horizontal evaluation.

According to the test results, First Horse Strength Pioneer 600 M's+3.3V output ripple reached 74.4mV, which exceeded the limit and was judged as unqualified.

six Summary and analysis of power supply horizontal evaluation

Based on the test results of this power supply horizontal review, Xingu GP600W ATX3.0 has better performance in various tests, especially in terms of efficiency. Of course, this is the only product in this horizontal review whose price exceeds 300 yuan. It is suggested that players with more budgets should choose it, so that they can be more relaxed in different aspects. If you don't pay attention to the energy saving brought by efficiency, the stable output of Hangjia JUMPER 600 and the chief player DK PREMIUM is more suitable for game players.

A total of three of the 12 power supplies selected for this horizontal evaluation were judged as unqualified, namely GAMEMAX's VP-600, Xianma's strength pioneer 600M and Jinheda's G6. It is recommended that you avoid them when choosing. The results of this horizontal evaluation are only valid for the purchased batch of products. It is suggested that you should continue to pay attention to the brand and product dynamics.

If there is no high requirement for power supply, select qualified products. In addition, the power supply of Xingu and TT in this horizontal evaluation provides a 5-year warranty, while the other power supplies are 3-year warranty. You can also pay attention when selecting products.

Finally, we also remind you that the performance of the power supply is related to the stability and safety of the whole machine, so don't overdo the power supply when building the platform compress Budget: 0.4 yuan/W should be the minimum for selecting power supply. In addition, when purchasing products, you should choose formal channels and official stores. Don't be greedy for cheap to avoid heavy losses.
