Delta 1400W Power Supply Review

Power supply model: DPS-1400AB A

Brand: Delta

Rated power: 1400W

Power supply appearance

1: Power supply body.

2: A fan.

3: 4 6-pin cables.

4: About 3.2KG (6.4 jin)

5: Length: 24.3CM Width: 10CM Height: 15CM

The overall appearance of the power supply adopts trapezoidal gray frosting treatment. The silver-gray shell makes the power supply look very domineering. It is exactly the same as Delta 1300W power supply.

Power nameplate

This Delta Gold Power Supply has a rated power of 1400W, dual 12V output, one current limit is 61.5A MAX, belongs to low speed mode, and has a silent function. One current limit is 123A MAX, and the maximum output power can reach 1476W, which exceeds the total power by about 0.05%, and the output capacity is very good.

Power tail

The tail air outlet adopts hexagonal trapezoidal honeycomb heat dissipation holes, and the structure inside the tail can be clearly seen, which can achieve good ventilation effect for the power supply.

Power supply fan

Fan: Comes with a built-in fan for good ventilation.

Fan power consumption: 65-75W

Silent function: Yes, below 650W is low speed mode, above 650W is high speed mode.

Noise: about 74.3 decibels, computer noise is about 60 decibels, and household ceiling fans are about 75 decibels.

Conversion rate: 91.3% (white brand 80%, bronze 85%, silver 88%, gold 90%)

Working temperature: about 33 degrees (ambient temperature 30 degrees during testing)

Advantages: high conversion rate, durable.

Disadvantages: Very noisy, large in size, not suitable for living room.

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 1400W 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: Delta DPS-1400ABA power supply is equipped with 4 6-pin cables, 50cm long plus 20cm long.

They are all high-specification 18-gauge electronic wires, which increase transmission efficiency and reduce losses.

To summarize: Remember: This power supply can only work between 100V~127V and 200V~240V. When tested at 48% load, the power conversion rate can reach over 91%. It is a gold medal power supply.

There are many types of Bitcoin mining power supplies, and the conversion rates are also different. If you need to use a Bitcoin mining power supply, the one in this article has a high conversion rate and is relatively cheap. For large-scale deployment, it can save considerable power cost investment. However, if you encounter some Bitcoin mining 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.
