Power supply for gtx 970

Hello everybody, I will be getting a either asus/msi/gigabyte GTX 970 soon over my hd 7850, and I wonder if my psu is capable of handling this card. It's Cooler Master Thunder M 620w. In http://www.coolermaster.com/powersupply/thunder-m/thunder-m-620w/ it says that this product is discontinued and it lead me into thinking that this psu might be bad? However for the past 3+ years I hadn't got a single problem with it.

Rest of the specs:
i5 4690
8gb ram
Asrock mH97 pro 4 motherboard
1TB HDD & 60gb ssd

Thank you

 

Should be no problem running gtx970 with that psu, my runs on a decent 550w (4 years old), if you wont overclock and overvolt both cpu and gpu to draw more than 500w under load, than you are safe.

 

It'll power it but that's not a very good power supply regardless.

 

Thank you for replies, I've no intention in overclocking

 

600 watts PSU will do for video card 970 GTX. I actually just read this informationo on another page. If your going SLI in future then 600w wont be enough. gl

 

Here's a calculator. Certainly 620w is more than enough.
