I'm following this guide* for a litecoin mining righ, but I'm using R9 290's instead of 7950's (on account of their basically sold out globally) and I'm baffled by how power supplies work, 500 watts for 1 card, 750 for 4? Any way, if theirs a formula please let me know,
How many watts do 3 Radeon R9 290's require?
