I've just ordered a Pico 12V 120W DC-DC PSU, but have no idea what kind of power adapter I can get away with.
Any advice on the cheapest power brick?

I've seen a few on ebay, but just wanted the advice of you guys before I fry my new htpc Smile
Thanks.

You can order it from here- picoPSU-150-XT + 102W Adapter Power Kit

If you want just the power brick, you can get this one- 102w (12v/8.5A) AC-DC Power Adapter with Power Cord

If you want a cheap one, I've had good luck with the "Kinamax 72W 12V 6A adapter for LCD monitors" available on Amazon.

Just know the maximum amperage rating of the 5.5mm barrel jack on the picoPSU is 8.5A (102W / 12V). If you need more, get the 4-pin mini-DIN connector from mini-box and get a 4-pin power supply that matches. IIRC, they sell the 4-pin mini-DIN "mini-fit JR" jack separately. That'll only get you 18W more though so not sure it'd be worth the hassle.

I'll have a few new 84W 12V AC adapters available soon.

Great, thanks for the advice guys. I'm gonna go with this one from eBay http://www.ebay.co.uk/itm/12V-10A-120W-A...2653wt_952

I'm still a little confused with the DC-DC of the PSU and the AC-DC of the adapter. No problem there...?

I'd read somewhere that the max amperage rating on the 2.5mm*5.5mm jack was 8.5A. I will try to find the information again. A 120W 12V adapter would be 10A so that would exceed the spec for the jack and possibly create a hazard (melt? fire?). If I can find it I'll post it.

[Edit]
Found it. "Input current should not exceed 8A. For current higher loads, we suggest using a 2x2 mini-FIT JR as an input connector." It's actually in the 150W picoPSU manual and it's talking about the wiring harness with the 2.5mm*5.5mm barrel jack. So, maybe it's 8A, not 8.5A which I'd assumed since the largest single pin AC adapter they sell is 102W.

Indeed, it would defeat the whole silent purpose of buying the thing. The flex psu of the Lian Li that I bought is too much for me already (as well as the electrical saving as I have it on 24/7) so the one I posted earlier seems to be without any fan.

I see from that thread that I may need the molex to p4 cable. Why the hell don't they include this in the item? I hadn't even realised the molex connector.

Thanks a lot guys.

I have bought from 321short-circuit on eBay and I've been 100% happy with them.

This looks like a nice kit:
http://www.ebay.com/itm/picoPSU-90-12V-7...0834084341

With a system that uses an APU, 1 or 2 HDDs, ODD and even a few USB components you'd be hard pressed to max that out. I could not max out a 84W AC adapter with even a HD5450 GPU dropped in.
