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.
