Over-active lover of Zeus with new god (8)

I believe the answer is:

hyperion

I'm a little stuck... Click here to teach me more about this clue!

'god' is the definition.
(Hyperion is an example)

'over-active lover of zeus with new' is the wordplay.
'over-active' becomes 'hyper' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'lover of zeus' becomes 'Io' (Io was a lover of Zeus in Greek myth).
'with' is a charade indicator (letters next to each other).
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'hyper'+'io'+'n'='HYPERION'

Can you help me to learn more?

(Other definitions for hyperion that I've seen before include "Satellite of Saturn - Titan - Keats poem" , "Saturn's moon" .)

I've seen this clue in The Times.
