The Best Ethereum Mining Rig
Ethereum Mining Precursor
There are two approaches to reducing power costs when mining Ethereum (or any cryptocurrency):
- You can reduce the total wattage consumption of the system.
- You can maximize the amount of cryptocurrency mined relative to its power consumption.
GPU
The most energy efficient of these is the AMD Radeon RX 460 or RX 470 (or the pricier RX 560 and RX 570). The RX 470 pulls around 145 watts, with the recommended power supply for it producing around 350 total watts. The RX 460 on the other hand, uses a total of 75 watts. That makes it easier to deploy on single-card mining rigs.
Power Supply
A picoPSU generally supplies power somewhere under 200 watts. It also tends to offer higher efficiencies than standard power supplies, at around 80 to 90 percent efficiency. If you’re using an RX 460, you can get away with a picoPSU.
Processors
AMD released two different lines of processor that offered a winning combination of low power consumption, low cost, and a full PCIe slot: the AM1 platform and a series of motherboards with soldered-on processors. Of these, I prefer the ECS KBN-I/2100 — but these tend to be hard to find and overpriced. Fortunately, the AM1 platform provides similar low build cost and low power consumption.
