Best HTPC PSU - 430-560 watts

I am building a mid-range, mATX HTPC system with the following components:

- Antec Fusion case
- Athlon X4 630 with stock fan
- Gigabyte mATX with Raden 4290 onboard Video card
- 4 GB DDR1333
- Asus Bluray
- FUTURE upgrade to ATI 5500 video card

So, looking for a good PSU to ensure it has enough power, and yet is quiet in the audio rack. I think I don't really need anything more than 430 watts, but if I do, please let me know.

Was thinking of Seasonic, but they're a bit more $$ than Antec, OCZ, Corsair for 430-500 watts PSU... however Seasonic has much better reviews overall and whils other PSUs get mixed review on noise, Seasonic gets very positive...

Any feedback is appreciated!

It doesn't matter what the rated output of the model is but rather how many watts are on the '+12v' rail(s). A good 380w there will do nicely, at load too of-course.
Look for 80+ certification, they're generally the quieter ones. Having a 140mm fan isn't a necessity either (80mm fans are quieter). Don't get an Antec Basiq either, although it's one of the top-5 brands, that product-line has a bad reputation.

What's your budget?

Here's a good Seasonic for $70.
S12-II (520w) @ 480w effective

I have Antec's version of this myself but with the 140mm fan and it's brilliantly efficient/quiet. Powerful too!

I generally recommend Seasonic PSUs or PSUs made by Seasonic for other brand names.

A Seasonic 330w - 380w PSUs are enough for your build and are not too expensive. I have a 5 year old Seasonic S12 500w in my HTPC, it is pretty quiet. In fact, I hear my other quiet fans over the PSU fan.
