Corsair CX650f to run multiple cards

[Stalker_26]

Hi all,

Am I correct in thinking that the CX650f won't have sufficient power to run three RX580's for mining 24/7?

Found somewhere that each RX580 at stock 24/7 100% load draws approx 136w.
By that the three cards would pull 408w.
I will have three 120mm fans and two 90mm fans plus an SSD.

Sufficient?
Or upgrade quite a bit?

Thanks

Sufficent? probably but I wouldn't risk it! CX650f is Bronze rated anyway, if you could up the power & 80+ gold, that may make you sleep better at night knowing the mining rig has less chance of going bang due to its lesser PSU. Depending on how long you intend to run said mining rig, a gold rated PSU may make sense in the very very very long term in terms of the the leccy bill.

If you undervolt you can shave a lot on a stock one and I'd be more comfortable with the PSU. But, spending money on PSUs adds to the payback time if it is going spare.
