Is my psu enough for gigabyte gtx 980 g1 gaming

Solution
The availability of good units is somewhat limited from what I can see, but this one will not fail you: http://nikem-bg.net/computer-components/Seasonic-FOCUS-Plus-SSR-550FX-GOLD/
Opss sorry for answer down I'm new and I can't where to reply anyway my psu is some Chinese cpu i7-870 ram corsair 4x2 1.5V I don't remember the motherboard
 


That is a disaster waiting to happen - melted connectors, plus a PSU with no protections will result in a mess. If you can afford a GTX 980 you can surely spend something like $60-70 for a decent PSU.
 
Wattage is not all that matters - quality is more important. Plus that be quiet unit is a bit overrated - it's total wattage is 600 W, but 12V line load, that matters much more, is only around 550 W. Although it's not that awful as you can find - there are units marketed as 600 W that can actually do no more then 300 W.
