Looking for SILENT Modular PSU

I'm looking for a modular PSU that's above all SILENT. I know a lot of companies like to brand their products as silent when in fact they make quite a lot of noise, so I was wondering if you had any recommendations of ones that are truly quiet in practice. I need to power this system:

CPU: AMD FX-8150
Motherboard: ASRock 880GMH/U3S3
RAM: Corsair Vengeance 16GB
Hard Drives: 2x Western Digital 2TB SATA III
Graphics Card: Sapphire HD7870 (subject to change, but that's my likely choice)
Optical Drive: LG BH10LS38.AUAR

Budget is as cheap as possible (obviously!)

Thanks!

If you want silence then look at the recommendations over at SPCR: http://www.silentpcreview.com/article699-page1.html
Another great article on PC power consumption in modern PCs: http://www.silentpcreview.com/article1245-page1.html
Your PC likely won't consume any more than 275-300W at full load unless you OC the GPU/GPU....OCing is not conducive to silent computing.

What case are you using? Are you going to use a fan controller to slow down/reduce noise from your case fans? If not, then seriously consider it. You can use Speedfan to control the GPU fans. Primarily a gaming or gaming/multimedia PC?

Don't forget how inefficient the whole lineup of FX chips are and how they can pull crazy wattage when overclocked.

Seasonic PSU's tend to be extremely quiet, I would go for one of theirs. The X-560 would be best if you have the budget. The fan doesn't even spin when pulling under 200W or so. Even when it does spin it is extremely quiet. If you can't afford that I would get their modular 620W model.

EDIT: Here are the links:

Thanks for all the suggestions! It seems that Seasonic is unanimously the best brand. As for over clocking, I won't be doing it often (if ever). The stock speed is good for me, and I don't really see the point of over clocking it. I might try it once but it won't be constantly on OC.

I think I'll stretch for the X-650, just for that added security. I want to be comfortable with wattage, I don't want it to be a squeeze, especially as I might decide I want to upgrade some components when the time comes.

I used to listen to and believe everyone who says that Seasonic are the best when it comes to quiet PSUs. But then I read reviews which actually measure fan speed of PSUs and turns out that the majority of Seasonic's design, until recently, aren't any good on load, even with their (high wattage) X Series units. So as long as you keep below 60% then they will be good for you.

I'm not saying Seasonic is bad, just not significantly better than the competition.

Silvune: What site(s) are measuring fan speed? Do you know any that are separately measuring dB from the PSU? SPCR was great for a while, but the frequency of their reviews has gotten limited.

I don't usually pay much attention to decibel measurements as SPCR is the only site from which I would accept those numbers and even then they are fairly subjective.
Xbitlabs is probably the best site for measuring fan speed, their reviews are probably once a month on average, but they usually test more than one PSU at a time so there's plenty of density of info in terms of fan speeds.
ITOCP and Chiphell are Chinese sites which often review PSUs and measure fan speed.
Sweclockers are another trustworthy site which measures fan speeds, but only at four points throughout it's load range.
Older Anandtech reviews (done by Christoph Katzer) sometimes measure the fan speed curve of units; I don't know if all of his reviews measure fan speeds because I haven't read them all yet.
