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.
