Everything was working fine until I decided to put my RX 580 in my computer which has a GTX 1080 in it. I was wondering if an MSI Z-series Krait MOBO, a GTX 1080, RX580 8gb, 32 gb of ram, SSD, Hard Drive, and an i7-6700k clocked at 4.5 GHz is too much for a 750w PSU. I want to use the RX 580 to mine Ethereum. According to a PSU calculator all of that should only be drawing about 575w. PLEASE HELP! ANY SUGGESTIONS?
