Will 500W PSU handle my hardware and which one to chose?

[Alex-under-bed]

Hi there.

I am making a station for programming, web surfing and watching [strike]pron[/strike] movies moslty. I wonder if a cheap PSU will do the trick and keep me running with the following configuration:
CPU: i5-3470 quadcore 3.20GHz
RAM: 8GB RAM
Motherboard: ASRock B75 Pro3
GPU: GeForce GTX 550 Ti
SSD: 120GB Kingston

And I am choosing from the following list, since I'm a on a low budget atm:
1. Enermax MaxPro 500W
2. Corsair VS650 650W
3. SeaSonic S12II series 520W 85+ (Bronze)
4. Thermaltake TR2 S 500W
5. Cooler Master G450M or G550M
6. Zalman ZM500-GLX 500W or ZM-500TX

I would really appreciate any help and advise.
PS: I really like having silence in the room for concentration, so loudness would be my nr 2 concern after quality.

Actually the Enermax is a good unit, if the Seasonic was a lot more money or not available it would be fine. Otherwise I would grab the Seasonic.

Thanks guys, I guess Seasonic it is, considering the price difference in 1 euro. Would 500W be enough though? Any idea how to calculate that?

More than enough. The easiest guide is to just use your GPU

As you can see there the 550ti needs a 400w PSU for the whole system. You're not using high power draw parts (like an AMD FX) so you're good.
