600W enough for my system?

[Kuosa]

I have almost finished a new build I am working on, I have a Corsair BS 600W psu running a Gigabyte z87 mobo, i5 4670k, stock cooler (for now) 2x4GB g.skill ripjaws kit, Corsair led case fans an 840 evo SSD and a Seagate 7200rpm hdd. I am looking to order a Sapphire toxic r9 280x 3gb. I have used the cooler master psu calculator which said a 495W min psu and another site saying 900W. There is no way i can make a judgement based on such contradicting results. I know the Sapphire site reccomends a 750W but that sounds like overkill as i have seen reviews of people running it OC just fine on a 650W.

So my question is a 600W handle it? Since it is a brand new psu that has surpased its return date so i need to know ASAP whether a new psu is order?

Thank you in advance!

dont use cooler master psu calculator... They will not even tell u approx wattage.. Use this psu calculator http://www.extreme.outervision.com/psucalculatorlite.jsp And r9 280x needs more wattage... If u want to use this gpu then use a 650 watt psu and if u want to keep 600w then use an r9 270x toxic...........

This is just my personal view. Do check your psu wattage from provided link

600 watt is enough for your system just keep your oc to a moderate level its good to have some headroom....and r9 280x requires 30amps @12+volt rail and a minimum of 550 watt of psu so a good 80+ 600 watt psu should be fine if u don't or keep the oc to a basic level...
