Another year (maybe longer) and I'll get a raid card and maybe upgrade to a 120W PicoPSU?? I digress, I need this for now.
So I'll jump on the Atom with only 1 hard drive, its all I need now, two soon, and small = good for me right now.
So bundle 80W PicoPSU, power cord, Atom 510e on the MSI Wind board here
. Seem good?
EDIT: The board has a spot for a 4-pin CPU power plug, and PicoPSU does not. Is this a problem?
As previously said, you'll need a molex to 4pin adapter; PicoPSU's were at first build for VIA boards that didn't have 4pin plugs on the board.
About AMD vs Atom and powering it thru a 80W PSU. The Atom will work, no doubt about it. I'm also of the opinion an Atom DC + RAM can't possibly go over 20W unless it's "helped" by a very inefficient PSU (such as mine).
The AMD rig... some math is in order. I've read about some folks that busted their PicoPSUs although they were well ventilated and the rig didn't surpass PSU's rated power - the reason not all that power can be given thru the +12V rail (and AMD/Intel regular CPUs are powered only thru the +12V rail)
Here's a manual of a 120W PicoPSU I've used for a while:
You'll notice it can take 6A on the +12V rail, which makes for a grand total of 72W @12V. An Athlon X2 has a TDP of 65W, and other components are likely to pull from the +12V (search Xbitlabs.com for HDD's per-rail Amp intake).
I doubt even my 120W PicoPSU could power a stock Athlon X2 setup. However with undervolting (and at worst with underclocking) it may be done; some graphics memory radiators on the PicoPSU's mosfets to help with the cooling and it should be an efficient and stable setup. It's obvious a 80W PicoPSU would cut it short, the risk is too great you won't be able to reduce peak CPU power consumption enough to fit the power envelope.
Bottom line: my preference goes towards undervolted AMD + 120W PicoPSU, but if you don't wanna take the chance or the 120W PSU is over-budget the Atom setup can get the job done just fine. Imho if you have only a green HDD, if you try to stream simultaneously on 3-4 devices it's not gonna be the CPU or the network that will limit you, the HDD access time will become an issue ahead of the others.
