Yes it can. IIRC, it's the standard 100-250V 50-60Hz

<p><a href="http://www.butterflylabs.com/product-details/" rel="nofollow noreferrer">Its website</a> says it uses 80W of power, so that's too much for a USB port. How does it receive it's power?</p>

[Its website](http://www.butterflylabs.com/product-details/) says it uses 80W of power, so that's too much for a USB port. How does it receive it's power?

Can it run on a 240V power supply, or does it need 110V?

Note I'm not asking about the newer "Bitforce Single (SC)", which hasn't been shipped to anyone yet. This the older (FPGA?) hardware that has been sold for some time.
