What is the Power Consumption of the ZeusMiner Blizzard Scrypt ASIC

We’ve read some comments about people complaining from the stock ZeusMiner Blizzard Scrypt ASICs’ like them being crappy and getting too hot. From our personal experience we can also confirm that the 60W power adapters provided with the miners do get hot, but this is to be expected with a power draw of the device of about 44W at 300 MHz and 48W at 328 MHz. Our unit that we are currently testing is hot to the touch, but only using that to judge can be misleading as any temperature higher the one of our body is perceived as hot. Anyway, we did decide to try using the Blizzard miner with a high-quality ATX power supply and measure the actual power draw we are getting…

We have attached the ZeusMiner Blizzard to an 80Plus Platinum power supply and the result was a bit surprising – very low efficiency of the power supply due to the low load. Clearly the 1200W Corsair power supply is not designed to be very efficient with a load of just about 50W, actually 48-49W measured as used by the miner, so not much different than what we got from the standard PSU. The difference here however is that due to the low efficiency that the PSU is running at the actual power consumption of the miner off the power socket is about 64W. We did measure 48W of power usage with the stock power adapter supplied with the miner at the power socket, so it seems that these 60W power adapters are quite efficient in converting the 220V power to 12V. Of course by increasing the number of miners connected to the power supply and raising the load to at least 10% or more the efficiency should increase and make things right, though no point in running just a single Blizzard off an ATX computer power supply – better stick to the power adapter supplied with the miner.

What is the Power Consumption of the 27 MHS GAWMiners Falcon Scrypt ASIC

We have been using and testing the 27 MHS GAWMiners Falcon Scrypt ASIC miner for a few days already and we did measure the power requirements of the device and are ready to do some recommendations for a suitable PSU to use. On the GAW website the power consumption of the miner is stated as 1040W and since this is essentially a ZeusMiner THUNDER X3 inside, we have also checked the specifications announced on the Zeus website – 920W. Zeus however does recommend a 1200W modular 80PLUS Gold or Platinum rated power supply to be used for this miner, though you can actually do well with a slightly less powerful model if it is a good one.

As you can see from our measurement on the image above, where we are using a Corsair 1200W 80Plus Platinum power supply, the actual power usage of the miner is 916W, so very close to what Zeus has stated on their website. The fact that we are using a more powerful 80Plus Platinum power supply gives us very high efficiency of over 94% at this serious load, so the total power consumed at the wall is roughly 970-975W. This means that even with a good quality 80Plus rated 1000W power supply you should be fine. No need to go for 1200W as recommended, though the higher power model will most likely help you minimize the power wasted as it will be operating at better efficiency when not pushed to the limit. We did a test with a 1000W power supply that was barely managing to work at 78-80% level of efficiency and got a power usage of almost 1100W at the power socket. So if you want to save yourself some heat and waste less power, you better go for at least 1000W power supply that is rated 80Plus Gold.
