Dell 550W Power Supply Review

Power supply model: DELL-AA23300

Brand: Dell

Spare part number: X0551,JD090

Rated power: 550W

Power supply appearance

Appearance components:

1: The main body of the power supply.

2: A power cord.

3: 2 6-pin cables.

4: A power supply fan.

5: Net weight is about 1.35KG (2.7 catties)

6: Length 33CM Width 7.8CM Height 3.9CM

The appearance of the power supply adopts the design style of the long series, and the silver-white shell makes the power supply look full of design sense.

Power brand

INPUT

100-240VAC 8A MAX

50/60Hz

OUTPUT

550W MAX

+12V 44.5A MAX

+3.3Vsb 4.9A MAX

This Dell power supply has a maximum output of 534W and a DC12V output current limit of 44.5A.

It accounts for about 97% of the total power, and the output capacity is not bad.

Power supply side

The side of the power supply can be ignored. The 550W power supply has its own fan at the rear for front and back ventilation, one in and one out, which can fully achieve the heat dissipation effect of the power supply. The heat dissipation is very good, so there is no need to consider the ventilation problem. There is an introduction below.

Power tail

Fan: Built-in fan, good heat dissipation,

Fan power consumption: 20-27W

Noise: About 58.6 decibels, computer noise is about 60 decibels, and household ceiling fans are about 75 decibels.

Noise: Low noise, not suitable for living room.

Conversion rate: 97.09%

Working temperature: about 33.3/35.1 degrees (ambient temperature 30 degrees during testing)

And there are 3 LED lights respectively. Note: View from above.

1: Green light, working light.

2: Yellow light, overload protection light.

3: Green light, power on.

Power cord

The power supply is equipped with a 220V input power cord. In order to reduce the operating loss of the mining machine, the 670W uses pure copper national standard 3X0.75mm² wire with a length of about 1.5 meters; the national standard 10A plug is suitable for all domestic mining farms.

Power cable

Cable: Dell-AA23300 power supply is equipped with 2 6-pin cables, 50cm plus 20cm in length.

50cm are all high-specification 16-gauge electronic wires, and 20cm are all high-specification 18-gauge electronic wires, which increase transmission efficiency and reduce losses.

To summarize: Remember: the power supply can only work between 200V and 240V.

There are many types of server power supplies, and the conversion rates are also different. If you need to use a server power supply, the one in this article has a high conversion rate and is relatively cheap. For large-area deployments, it can save considerable power cost investment. However, if you encounter some server power supplies with low conversion rates, you must consider the electricity cost, safety and stability.

However, it should be noted that different ambient temperatures, different mining machine temperatures, and different mining machine fan speeds will all affect the total power consumption, so the above figures are for reference only.
