Total wattage means very little when it comes to PSUs. It all depends on the +12V rail(s) of the PSU. That is the rail that powers all the heavy load devices. Older and cheaper PSUs used to put all the load capacity on the other voltage rails.
Normall, the HD-7870 would require a 500W PSU. But there again, it depends on the +12V rail's amps and total watts.

That means nothing. You need to provide the ratings for those voltage rails. Amp? Watts? Or just post a picture of the PSU's nameplate.
But if your 410W PSU is handling a HD-7870, it probably is OK. You would have noticed shutdowns or re-boots by now if it was overloaded. However, you probably are taking the PSU beyond its 80% efficiency range.
