question about power supply for Intel D410PT motherboard

[harvt5]

I am looking at the Intel D410PT .. it's an embedded system, a motherboard and processor.
The "product guide" is here

http://downloadmirror.intel.com/18358/eng/D410PT_ProductGuide02_English.pdf

What small fanless power supplies can it take?
which ones are reliable? or not reliable?

The "product guide" says on p36, 2x12 connector.
(so, 24-pin)

Will it take a power supply with a 20pin ATX connector?
If so.. are there any negative consequences to that?

A 250W PSU with a 24-pin ATX connector is what I would buy.
Depending on your case, you should pick a TFX, a SFX or an ATX form factor PSU.
The ATX form factor allows different configurations of chassis and power supplies. Several standard power supplies exist including those compliant with ATX12V, SFX12V (Small Form Factor with 12V Connector), and TFX12V (Thin Form Factor with 12V Connector)
The TFX is (85mm x 63mm WxH) .
The SFX is (125mm x 76.5mm WxH).
The ATX is (150mm x 86mm WxH)

Here you have a good TFX PSU:

Seasonic SS-300TFX 300W

A good SFX for factor PSU is this one:

Seasonic SS-300SFD 300W

A high quality fanless ATX PSU is this one:

Seasonic SS-400FL 400W (the best of the best)

The Nexus Value 430 is not fanless but is extremely silent and it's much cheaper.

Note- I am only interested in fanless..
3 of the 4 you mentioned, have fans. I don't want that.

The one fanless one you mentioned is rather expensive though..£115 and I don't think I need all the watts.


my plan is the whole thing is fanless.

no case.

any hard drives would be SSD.

a most basic graphics card.

Do you know if the PicoPSU is reliable?

There's a 90W one. and a 150W one.. and others.

I would also like to know if it'd be OK plugging a 20pin PSU in (since I have some lying around, and I may use one for a while some time). I heard there can be a resistance issue doing that.

The 24 pin mobo connector is actually just the old 20 pin connector with 4 extra pins added on the end which are not separate rails. They're just extra lines to provide more current to the same rails.
If your motherboard's current requirements are low enough then it will work properly with only a 20 pin power cabled plugged in. But if it isn´t, then you can overheat the ATX connector. When you plug a 20 pin cable into a 24 pin connector you're not providing the extra current carrying capacity which may be needed by the mobo.

Concerning the fanless PSU, Silverstone and Be quiet! have some cheaper fanless ATX models. Anyway, I recommend you not to go for a fanless PSU. They are more expensive and fail more often.
Besides, I wouldn't install a fanless PSU in a fanless case. I would install one exhaust fan inside the case at least. But this is just my opinion.

It should be reliable. The 150W and 160W versions are 24-pin while all others are 20-pin. Some of the lower wattage ones also do not have the 4-pin CPU plug, so read the specs carefully. Your motherboard choice (without video card) will probably only need 40W max even with one SSD.

The board has one PCI slot, so you aren't going to get much of a video card in there, so add another 20W or so.

Have you considered something like this motherboard? It has everything you are looking for - passively cooled, comes with a power brick (something like PicoPSU integrated on motherboard), comes with better video so you don't have to put in a PCI video card and nothing sticks out of the slot so you can put it in really slim cases or since you're not using a case, you can just mount it anywhere without having to worry about the video card sticking out.

Note that Zotac makes a number of models, some without the integrated PSU. You have to register the product with them as soon as you receive it for warranty purposes. I think Asus makes something similar.
