The "staples" that you'll have to try out: Stratovarius, Helloween, Blind Guardian, Gamma Ray, Iced Earth...

If you can stomach a little cheesiness, power metal is awesome. A very fun genre, enjoy!

Pantera and Five Finger Fruit Punch are about as far from power metal as you can get. Mercenary is the only decent power metal band.

Pantera's not Power Metal, not trying to be a jerk, but I'm just sayin.

Iced Earth

Judas Priest

Manowar

Helloween

Edit: Exodus is a Thrash Metal band

Edit2: MegaDETH and Suicidal Tendencies are Thrash bands too.

Well, Pantera did make an album called Power metal, but they consider it not canon (i.e. before they recorded Cowboys from hell and became a Southern/groove metal band).

Besides those mentioned:

Wuthering Heights

Manticora

Angra

Jag Panzer

Nocturnal Rites

Helloween

Dio

Iced Earth

Dragonforce

Speed of Light

Calling FFDP power metal is like calling Slipknot death metal or RATM progressive. It made my day.

You should start with the basics like Blind Guardian

Try Nevermore or Eyes Set To Kill

IdrA Is a fail troll

Sonata Arctica! \m/
