The Motorola box is actually for one of their phones made yonks ago. The Hiper 200W does fit but the cables are the main problem and I am wary of modding the cables TBH. I do have one of the 250W Shuttle PSUs which still works,so I might just use that as an external PSU with power extension cables.
Possibly, or that my mobo was a particular power hog (785TD-M EVO, so all the bells and whistlesOriginally Posted by watercooled
). I seem to remember comparing power draw with someone else on here who had an MSI board and the Sempy and they were getting significantly lower power draw than me. I'm not surprised that the Llano rig's OK, I was impressed by how good the power management is on it (although mine seems to have a paddy fit when I start a DVD playing and it leaps to > 100W for about 1 second before settling down, so I couldn't run that on a Pico
).
I still need to do something with all my old PC bits - I've got a couple of workable rigs that I've just not got round to using! All nice and low power though, lots of 45W CPUs kicking around in my bits box

I would say definatley go for a much higher rated psu, something like
http://www.google.co.uk/products/cat...ed=0CDAQ8wIwAA
should do fine. Also don't forget any lack of power can give you strange instabilities you'd never figure out!

The FSP is a different PSUSorry, I thought my personal experience of that PSU not powering an ASUS 785G mobo and Sempron 140 might have some bearing on CAT's decision
I've personally run a ZOTAC GF9300-G-E with an E3200, SDD+3.5HDD+ODD on a 120W PicoPSU and never had any issues.
CAT-THE-FIFTH (07-09-2012)
True, but it's the one that CAT was considering buying. So it might be fairer to say that the 90W PicoPSU is a different PSUThe FSP is a different PSU
If the 90W Pico does pass the 12v straight through from the power brick then perhaps it would be OK. Personally I'd prefer more headroom though
CAT-THE-FIFTH (07-09-2012)
Ah, well you recommended he invest a 150/160W PicoPSU, hence why I defended its younger siblings
A 150W+ FSP, judging by your experience, would be totally justified however.
CAT-THE-FIFTH (07-09-2012)
tbf I've not seen a 150W FSP and was basing it off my experience with that rather than the Pico - I assumed that all DC-DC PSUs were made roughly equal. Might have to try a Pico at some point and see how it goes. I've got a low power Phenom II just waiting to be recommissioned into a home web server
CAT-THE-FIFTH (07-09-2012)
One thing to bear in mind with the Picos is that, because they pass 12v, you have to be careful the 12v brick you're using provides a decent/stable voltage and not too much ripple. I've found (based on the ones I've tested myself) the 12v FSP bricks are good in terms of ripple, despite the spec sheet listing max ripple as way outside the ATX spec.
You can see the standard Picos will pass 12v ripple through to the output side here: http://www.jonnyguru.com/modules.php...Story&reid=207

I did look through that JonnyGuru article a while back - the power block is very important,so this is why the combinations I am looking at,cost at least £60. I haveordered some ATX extension cables for the Shuttle 250W and I will see how that pans out first.

Righty! Ho! Managed to get a secondhand 150W picoPSU,although I am not sure what size the power block is!
No label on it?
On the subject of the FSP, I tested AC power draw with the 5050e platform and I can get it to draw 90w in the stress test, so even if the FSP could manage 90w on 12v it would be pushing it. As it is, it would probably boot but multiple HDD spinup or heavy load would likely trip it.

Well,the system will be basically a Zotac 9300 motherboard,Celery E3000 series CPU,2GB of DDR2,and one 140MM fan. The CPU will be cooled by a copper passive heatsink.
Edit!!
This is the picoPSU:
http://www.mini-box.com/picoPSU-150-XT
It uses a 12V power adaptor.
Second Edit!!
It seems the power adaptor is at least a 12V 60W!!
This is what happens when you are impulsive!!
Looking around for a decent 12V power block now. Looking at EDAC,FSP and some of the other better companies.

When I was looking for 12v adapters a few weeks ago I came across a place called Portable DVD Player Spares Ltd (catchy name huh?) who do several 12v 120w adapters e.g. this one. They might have one that fits your needs? Can't comment on quality or anything though but they're based in the UK and have a 90 day warranty.
Main - Intel Core i5 2300 @ 3.5GHz, 8GB DDR3 1333Mhz RAM, Asus P8P67 Pro, Coolermaster iGreen 600w, GTX 480, Antec One Case

It could work, but it looks very generic and the price seems too good to be true. You could give it a try if they accept returns, and ideally hook it up to a 'scope under load if you have access to one. Some generic ones have honest ratings and use surprisingly good quality components, but others can seem OK initially but use poor caps which quickly degrade.
Something else to bear in mind - since the DC output is floating (not grounded), some power bricks (mostly cheaper ones in my experience) can produce a fair amount of Earth leakage - the one included with a WD MyBook I had was actually painful if I touched a metal part while I was grounded somehow (connecting USB connector + bridging gap with my finger for instance) and it would cause my monitor to blank for a second when I connected it. If it's a problem, you could try grounding the case some other way. It also causes that strange fizzing/tingling sensation when you touch the metal case of some IMO poorly designed floating appliances, e.g. some laptops/DVD players.
A bit off topic but a somewhat common problem AFAIK...
CAT-THE-FIFTH (08-09-2012)
Did some research and supposedly the 200W 12V Dell DA2 is used by many people. OTH,I will need to modify it somewhat due to the weird power connector.
Hopefully,it will be not too hard to do:

The last solution looks easiest to do and basically inverts the following:

However,I am a tad worried about grounding everything properly though.
It's not really something you should stress over, especially with a decent power supply, just something to bear in mind. Some metal cased laptops also have the problem when they're plugged in.
