I can't find that PSU. If it is one of those case plus PSU combos. Then it is likely a piece of junk and won't handle the GTX 970.
Get an EVGA, Corsair or Seasonic 80+ Bronze 500w PSU. For a decent budget option. If I knew your country and total budget for a PSU and GPU. I may be able to make a specific recommendation.
You can also look at the PSU tier list. Then choose a series which is Tier One, Two or Three for a decent quality PSU.
