Bitcoin has become one of the most popular cryptocurrencies in recent years. The cryptocurrency’s popularity and growth have been driven by miners who use specialized hardware called an ASIC miner (application specific integrated circuit) which was designed specifically to mine bitcoins at high speed.
With so many people investing heavily into this technology, there are also plenty of companies that want to make sure their products can keep up with demand. One such company is Bitmain, whose flagship product is the well-known Antminer model S7/S9 series. These two models were released in 2017, and both are very successful. While they don’t come cheap either, you could say these machines are worth paying for if you think your wallet will grow significantly over time.
As such, it makes sense for anyone interested in buying or building an ASIC miner like the S9 model would need to invest in some kind of power supply unit (PSU). But why exactly does this matter? What do we mean by “good” and what should our selection criteria look like? Let’s take a closer look at all of these things below, however, before we proceed let’s go ahead and show you our favorite PSU picks.
Best PSU For Antminer S9
This PSU is most definitely the best option you could go with for the Antminer S9, it features 1600W with 80+ Titanium certification which would 100% be able to handle the Antminer S9 for years to come without a single issue.
One downside of this PSU is the price tag which is a bit expensive, but if you’re into mining for the long term then this is definitely a good investment.
This one is very similar to the previous PSU, it’s powerful enough to handle the Antminer, only difference is that it’s a Platinum certification instead of Titanium, so it’s not quite as high quality but it’s still top-notch and will be able to power your Antminer for years guaranteed. It also comes with the added benefit of being a little bit cheaper.
This is the cheapest option on the list, if you want to ROI ASAP from your Antminer & PSU then go with this option, it’ll work with the Antminer but it’s more prone to not last as long as not be as efficient in terms of power usage, so although you’ll save some bucks buying this one you’ll likely lose some in energy consumption over the years.
Nonetheless, the only major difference between this and the previous 2 is that this is Gold Certified instead of Platinum/Titanium and the fact that it’s a bit cheaper.
Why is a Good PSU Important For ASICs
A highly efficient PSU will save you a lot of money in electricity bills when mining bitcoin & will save you from having any possible short circuit issues that can completely ruin your hardware. Considering how much ASIC costs you shouldn’t be a cheap-ass on the PSU choice if you don’t want to have a bad surprise down the road.
In general terms, a good PSU means any device that converts AC electricity, usually coming from the wall socket, into DC power suitable for powering computers, gadgets, etc., but not appliances or other electrical devices. A typical household in Europe uses 220VAC mains voltage, while North America runs on 110VAC. However, even though different voltages exist across countries, the actual output current required from your computer doesn’t change much between them. So regardless of where you live, you’ll still be able to find decent quality replacement parts online for just about anything else electronic you may own.
When looking for a PSU, it’s important to note that wattage isn’t necessarily indicative of performance. Just because something consumes 500W of power doesn’t automatically tell us how efficient it is compared to others available in the market. This is especially true when shopping for something used since manufacturers often cut corners when producing cheaper units. As such, always ensure that you buy a reputable brand name PSU with great reviews, preferably from independent reviewers rather than Amazon rating scores.
