New build: low wattage (<20w) idle, totally passive, gaming HTPC

On the face of it maybe but actually I think the case its pretty cheap, people pay £90 for some non passive itx cases, and this one is very high quality, it's all very think aluminium and far cheaper than any other passive cases I could find.
 
I paid £11 for my 120w brick, it was actually advertised as a 12v 10a LED power supply but it had a 2.5mm*5.5mm connector which tends to be the standard for picopsu's.
 
Well you didn't say that in your list of requirements ;)

Edit: I have 3 xbmc machines here ranging from an older Atom/Ion to an E8400. Can't tell the difference between them for playback...
I agree I have a atom+ion and a celeron+ion (nd22) they run xbmc very well, on linux too which is a nice bonus in my book. My issue with them is the very poor idle power draw.

I keep my boxes on 24/7 (well just this box now) so idle power is important to me, I couldn't get the atom system to idle under 29w and the celeron was about 24>25w and when you consider there repetitively poor performace I decided on doing what I have done.

I get better idle power 24/7 as this box is now my home server + nas, and I now have headroom to play a bit of pro evo on the big tv when friends come round etc.
 
I've lent my power plug thingy to a mate but from memory it used about 1w for about 10 seconds which dropped to nothing, well least not anything that registered.

As I say memory isn't the best, I'll recheck it when I get the plug back.
 
Personally I think an 80w would be fine, even if it became borderline with added bits, knocking a little voltage off the cpu/ram/NB can bring total wattage down quite a bit.

Having said that 120w picos can be had for so cheap I don't see a good reason not to buy one.
 
Indeed I used the deluxe, the 19.5w was idle at desktop with everything enabled on the mobo (wireless, BT, audio, lan etc) and with a wireless dongle for keyboard/mouse in a usb port. Also:

*A6-3500 was overclocked to 3.65Ghz (but it gets automatically down clock to ~1ghz and reduce volts at idle by the mobo).
*4gb running at 2100Mhz, standard volts
*64gb Crucial M4

And nothing else, no mechanical drive or dvd rom etc.
 
Great, thanks, looks like I might try this mobo as well. It really is hard to get some good numbers for comparison of various mobo's... (for example, I will not be needing wireless or BT).

Just out of curiosity: Did you try switching off wireless, BT , etc and remove the dongle to see how low it could get?

A.
I didn't, but if you want to go crazy I reckon you could probably get close to 15w if not lower by undervolting.

Popular opinion is that the default vcore on a lot of the lower end a6's is too high. I run overclocked to 3.65 with a slight undervolt and its 100% stable, if you run stock I reckon you could knock a ton of vcore off it. Probably to the ram and mobo too.
 
Sorry, but what? (excuse the pun) are you running a a6-3500?

Pretty sure them numbers are just not possible. I guess you can draw some comparative results but your measuring device sounds way out.
 
Its almost the same as your device but you good be correct but i dont wish to buy another just to test it.

Yes a6-3500
Ok, in that case deffo take your pure numbers with a pinch of salt, still comparatively you numbers work for you

If you check this table: http://www.xbitlabs.com/articles/cpu/display/amd-fusion-intel-core-i3_8.html#sect0

It shows that the cpu ALONE pulls 8w at idle and 15.5w when playing a movie.

Bare in mind that these readings are taken directly off the cpu 12v rail so very very accurate.

Now factor in mobo, ram, ssd, hdd, etc and a psu efficiency of ~85% and you can see how way out your meter must be, in fact given your previous odd readings with it I might suggest its just plain busted :)

Bumping this thread to see what the results were.

The i5 is about 10w over the recommended so I'd love to know what happened (interested in getting an i5 and one of their cases).
Should be fine, cpu-z thinks my overclocked A-3500 is ~90watts TDP and it has perfectly respectable temps.
