Hi everyone.. Just got my grubby hands on a rog swift and will need to upgrade my radeon 6970. I read that with the GTX 970 i probably won't have to upgrade my psu.

According to the information here: http://www.hardwaresecrets.com/article/Corsair-HX620W-P...

"As you can see the label says this power supply has three +12V rails. These rails are “virtual” as all of them are connected together to the single +12 V “real” rail coming from the +12 V rectifiers through a series of jumpers (a.k.a. “shunts”). " Also on that link, it passed a 18.5A + 18A +12V1 and +12V2 test.

Edit: my cpu is a non-OCd i7-3770k running at stock. (max tdp is supposed to be 77W). :) 
512gb crucial ssd. two caviar black HD. random cheapo dvdrw. bunch of quiet fans (scythe iirc)

Should I be fine with this, especially given that it ran my radeon 6970 fine? Thanks!!!!

Should be ok. Recommended wattage is 500-600w depending on the cooler for the 970.
