Hello guys, I need a little help. I currently have a r9 280X from Gigabyte running with FX-8320 OC'd to 4.2Ghz on a be quiet! PURE POWER L8 600W. Currently I have no problems whatsoever but I will be exchanging the 280X for a 290 which I know requires a bit more power. Will that PSU of mine handle the 290? Thank you for help.
