I'd like to start a thread focused on Power Supplies choosen for different HTPC builds, what to look for, and resulting experiences.
I would start by separation into three form factors (below), make the assumption that a well ventilated case is being used, and have the general criteria be quite operation, good performance, and quality.
As a side note, eskro had references a Seasonic SS-400ET w/ 120mm fan and dual 12V rails. Good starting point and good value!
The three sizes of HTPC for PS selection:
1) Regular size ATX case.
2) Medium size Micro ATX case.
3) Small size Mini ITX case.

In case anyone looks at this thread, I'm posting what I ended up selecting for a PSU in my micro ATX case and noting a good alternative if you can accomodate a fanless PSU:
SeaSonic M12II 520 Bronze 520W (120mm fan) 80 Plus Bronze certified
Seasonic SS-460FL or SS-400FL (fanless) 80 Plus Gold Certified

any size chassis:
picoPSU 90W (CPU TDP up to 65W, 1HDD, no discrete GPU)
picoPSU 120W (CPU TDP up to 65W, 1HDD, low power discrete GPU e.g. GT530, HD6570)
+ power brick rated 90W will be fine for HTPC use, power draw should only be about 60W max, but add more for HDDs, unpowered USB devices, etc. PSU is 100% efficient, no conversion. AC/DC power bricks will differ in quality and efficiency, so don't scrimp to get a cheap one. Be mindful of fake picos on eBay, but they're usually easy to spot. Few places in UK distribute them. One genuine UK seller on eBay at the time of writing. There's not a particularly big market for them I guess.

Thanks for creating a worthwhile topic for discussion!!!
I'm a student, who is looking to build a customer HTPC, on a budget. I previously built one with my old computer, which ran off a full sized Foxconn motherboard, 1.6 AMD2 Sempron 64+, with 4GB DDR2 RAM (1x2GB, 2x1GB). The live version ran great, even with full HD movies.
I am currently using an Xtreamer Pro as a NAS server/media player, using 1x2TB WD Hard Drive, + 1TB Samsung.
I'm looking into an ITX motherboard, ideally making use of the AM2+ CPU and DDR2 RAM I have from my last build. My ideal system would include a DVD/Blu-Ray player and removal 2.5" sata hard drive, through a bay I have. I plan to run XBMC Live from a 16GB USB Drive.
I have just purchased the Gigabyte MIB T5140 as my case, which is equipped with a 65w power supply, with motherboard attachments, with a 5.5mm/2.1mm ac adapter/plug:
*AC Input 100-240v
1.5A
*DC Output
50-60Hz
12.0v ==5.0A MAX (60W MAX)
It has space for one 5cm fan, plus a vent for a fan above the CPU if required. I think this PSU will be insufficient and would hope to replace the AC Adapter with a high wattage version.
Can anyone advise me on what my power requirements would be and any suggested models? I am in the UK so eBay or Amazon is ideal.
On a side note, particularly because I think there is a lot of arrogance on the subject, what should I consider if I wish to move my hard drives from the Xtreamer to the HTPC, to run media directly from the same unit? The dual boot of the new Eden should make this worthwhile.
XBMC 13.02 'Gotham'
Windows 8.1
Zotac Ionitx F-E
Sandisk 32GB SSD
500GB Samsung 2.5" SATA Drive
4GB 800 mHz 240 pin DDR2 DIMM
Compucase 8K01 Mini ITX Case With 120w

I've used the Picopsus and they're a great solution as long as you don't have a larger GPU. I recently built a new XBMC client and it has a GT520 GPU - too much of a power hog for the Picopsu.
I ended up using the Seasonic SS-400FL. 400Watts and fanless. It also is a modular PSU. Quality appears to be quite good.
