I am about to switch from mining litecoins with my 2500k to a 7870 using either cgminer or reaper and I was just curious if you guys think a 500w psu would be able to power a 7870 and a core 2 duo machine with nothing else plugged in? Because if so, I'll just keep my 2500k mining on a seperate machine. and put the new card im getting into the old machine I have.
Or I could always swap my 1kw psu into the gpu miner and put the 500w one onto the 2500k machine
yes a 500w psu should do the trick for 1 card.
