Dell 750W Power Supply Review

Power supply model: DELL NPS-750AB A

Brand: Dell

Rated power: 750W

Power supply appearance

Appearance components:

1: The main body of the power supply.

2: A power cord.

3: 2 6-pin cables.

4: Length 33CM Width 7.8CM Height 7.8CM

5: Net weight about 1.8KG (3.6 catties)

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 nameplate

This Dell power supply has a maximum output of 750W, an output DC12V current limit of 62.4A, and a maximum current of 9.3A.

The total output cannot exceed 750W, accounting for about 99.% of the total power, and the output capacity is not bad.

Power tail

The power tail adopts square ventilation; the structure inside the tail can be clearly seen. And there are 3 LED lights. 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 750W 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 supply side

The side of the power supply can be ignored. The 750W power supply has its own fan for 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. The following is an introduction.

Power supply fan

Fan: Built-in fan, good heat dissipation,

Fan power consumption: 20-27W

Noise: About 69.3 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: 89.8%

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

Power cable

Cable: Dell 750W power supply is equipped with two 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 100V 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.
