Ideally around the 600-650W mark for one R9 390X. About 850W for two.

'Fanboyism is stupid' - someone on this forum.

Be nice to each other boys and girls. And don't cheap out on a power supply.

This is a fairly accurate calculator. I usually add 100W just to be sure though. http://outervision.com/power-supply-calculator

 

Then use this to pick out a good PSU that will last you a long time. https://linustechtips.com/main/topic/406160-psu-ranking-and-tiers/

The actual card and, say, a Skylake i7 should run at around 400W under load so use that however you will. I'd recommend the EVGA 750B2 or 650W GQ as they're both cheap and both are great PSUs.

My account is almost entirely dormant. Hope you all are having a grand time. Many years of fun were had here.
