Model Antminer S5 is another Miner from Bitmain mining Company. It comes with the  SHA-256 algorithm with a maximum hashrate of 1.155Th/s for a power consumption of 590W.

Overview

This version of the Bitmain bitcoin miner was released in the year 2014. It was regarded as one of the most efficient and fastest ASIC miners available during its release period. Ever since then, the S5 has been outshined by the latest models.

The Bitmain Antminer S5 has a hash rate of 1.155Th/s, an SHA-256 algorithm with a power consumption of 590w. The S5 is considered a good choice for hobbyist miners on a budget.

Power Supply

The Antminer S5 uses between 560-590 Watts at around 115 volts. With any sufficient powered ATX- power supply unit, the S5 will run without any problems. The efficiency of the power supply is rated as.

Gold: (10% of electricity wasted).

Silver: (20% of electricity wasted).

Bronze: (30% of electricity wasted).

An inefficient and unrated power supply throws electricity around and makes so much noise and heat. This is to be considered by miners or any aspiring miner when deciding on the Antminer series to purchase. In the absence of a 9V PSU under-clocking, the S5 is challenging. 

Power Efficiency.

The Antminer produces 1 Gigahash for every 0.51W consumed. The real power consumption of the S5 will differ according to the PSU efficiency and room temperature.

There are possibilities of increasing the S5’s hash rate by increasing its frequency, and when this happens, it also increases the miner’s power. This also increases cooling requirements.

Price.

The price of the S5 ranges from $190-299; they can be found on Amazon and eBay as used or second-hand. A brand new S5 costs $413 and can be gotten from Bitmain in China.

Properties

Noise: The S5 should not be run in your living room; it has a 120nm fan that produces more noise than an industrial vacuum.

Casing: The S5 casing has an opening on the top and bottom and lightweight plastics by the sides. This plastic casing weighs only about 2.5kg.

Setup.

To set up, you’ll have to configure your mining pool settings, and to do this:

I. Upgrade the firmware of the devices.

Ii. Share privilege access over a networked connection to other miners.

Temperature.

The temperature the S5 will function well should be below 80degree celsius /175degree Fahrenheit. To prolong the life of the S5, the temperature needs to be kept at a temperature below 60degree celsius/140degree Fahrenheit. 

Bitcoin Profitability.

Per day: -$1.5

Per Month: -$46.07

Per Year: -$552.87

The results are, as expected, not profitable. But it is possible to profit from an S5 if the Bitcoin price is higher and the power cost is cheap at a stable difficulty and improved efficiency.

If you want to learn the ropes of bitcoin mining, a cheaper second-handed S5 is an excellent choice because of its low-cost introduction to the complex business of Bitcoin mining. The S5 is also a great platform if you want to experiment with hardware, firmware, and software tweaks.

Pros:

• It is a low-priced miner, and second-hand is priced below $200.

• The power demand for the S5 is relatively low at about 590W.

• Its best use for newbie miners looking to learn and experiment with bitcoin mining.

Cons:

• It has a singular fan and can produce noise compared to that of an industrial vacuum.

• By all standards, it's low and has a hash rate of 1155GH/s. 

The Profitability of Bitmain Antminer S5

It comes with a profit ratio of -85 percent and an annual return percentage of -132 percent. There’s no payback period with this unit, and Bitmain seems not too confident with it. The power cost per day is $1.60, and the returns are $1.40
