Seasonic S12II vs Corsair Vengeance

[aespar]

Hey, after my medieval beQuiet PSU just died on me, I need a new PSU for my setup. I settled on these 2, Seasonic, can never go wrong with that I guess, and about Corsair I heard good things, yet dont know about the Vengeance Series:

Corsair Vengeance 650W 70€
Seasonic S12II 620W 65€

Cant decide between these two, and I dont wanna spend more money than 80€ for a PSU. Would they suffice for the future/overclocking?

My Setup:
GTX 1060 6GB
i5 2500k Overclocked 4,5 Ghz
Gigabyte Z68XP-UD3P
2 x 1TB Seagate 3,5 SATA
2 x 4GB Kingston RAM

I live in Austria actually, so it's always a tad more expensive. How long on average, until the gold PSU's last? Never dwelled into PSU's that much, but if the Golds last longer and are more stable, it's well worth the extra 20.

I think I'll go with 650W, and I can get Antec Earthwatts Gold or Bitfenix Formula Gold for 85€ around here,
