Re: Official FutureBit Apollo BTC Software/Image and Support thread
That's perfectly fine, using a 600W bequiet PSU here. (A PSU's efficiency sweet spot is around 50-60%, so consider that for your choice)
Maybe if you buy a 50% efficiency PSU in 1970
It is true that PSU's are most efficient at 50% load, but the variation is only 2-3% so you won't even notice it.
Most PSU's are rated at 80+ efficiency which means that a power supply is at least 80% efficient at 20%, 50%, and 100% loads.
Yes there are different 80+ ratings (bronze, silver, gold, platinum titanium) but they are just variations on the theme.
