I got myself a new 1080ti (havent received it yet ) and I wanted to give my card to my sister which has received my older parts recently. I was gonna skip the 1080ti because I tough the price was gonna be higher but I could not resist. So at that time I ordered for her a 500W psu along with a rx 480. I was gonna give her my r9 fury strix (air) and resell her rx480 but then I tough that her psu might be too weak. The rig consist of a 3570k oc'ed at 4.2ghz (~1.115V if i remember correctly) with 16gb ddr3 2400, asrock z77 extreme 4, 1 ssd with 2 hdd powered a evga 500W 80+ psu (100-W1-0500-KR) which has a 40 amp 12V rail. The fury would not be oc'ed (very poor oc on it anyway) from I've read it should work but the psu would be pretty much at its limit. What do you guys think ?
