How to fix the power supply?

Question

Do it yourself

Hello community!

I have the following task:
There is a mini itx form factor case, in which the motherboard is already installed. In this case, you need to install and most importantly fix the power supply. The problem is that there is no fastener for the block and you need to attach some kind of "crutches". Basic requirements: you can not drill the body, the connection must be collapsible.
So far, the only idea I have is to glue special elevator screws (they have a wide flat head). But the idea is apparently not feasible, since I did not find the required sizes of such screws.
Maybe you have experience of such sophistication?

Answer 1

So, thanks to everyone who gathered and discussed!
It was decided to use these magnetic mounts with a screw:

Answer 2

You can try to put it on cable ties if there are holes and the PSU is not particularly heavy.

1. Judging by the pictures, there are still technical holes. Or show pictures of what you have, not pictures from the internet.
2. The case is steel, the version with magnets is the simplest solution suitable for the specification.
3. If you do not plan to move the case much during operation, then you can place the power supply in a plastic frame (for insulation) under the size of the block, place the container with the block in a larger frame (to fit the size of the free space in the case) and leave it lying inside. frames must be connected to each other. On the outside, you can smear sealant or something else soft. I would take up such a collective farm if I had such a task and not a magnetic body.

Answer 4

It is done simply, a heated nut is soldered into a piece of plastic, this piece can be reliably glued. And the stand is already screwed into the resulting socket.

Answer 5

Glue gun.

Answer 6

Excuse my curiosity, but why can't the case be drilled?

Answer 7

Look: there are mounting holes on the power supply. So, they need to be used:
1. We cut out a platform the size of a power supply board from textolite (plastic)
2. In accordance with the location of the holes in the PSU, we cut the same holes in the prepared area (diameter 3.2-3.5)
3. On the reverse side countersink under the countersunk screw M3
4. We fasten the screws to the rack platform, apply glue to the screws so that they never unwind again:

5. Glue the plastic pad to the smooth side of the case with epoxy / torque / snot.
6. After drying, put on the PSU and fasten it with nuts.

Answer 8

If there are holes on the power supply itself or they can be drilled, then I usually put props (on the same eBay they can be found on the words “stand off”) and then screw them on with ordinary screws.
Similar props usually secure the motherboard itself too.
I usually glue the supports themselves to the body if it is metal or melt it if it is plastic.
There are a bunch of different options. Something like this:

Answer 9

The problem is that there is no fastener for the block and you need to attach some kind of "crutches". Basic requirements: you can not drill the body, the connection must be collapsible.

And I would take a plate with holes, stamped in such a way that the bolt head does not stick out above the surface, for example, a piece of the PSU body would screw in the bolts on which we will mount the structure (those same “crutches”) on which the PSU will already be attached and glued the plate inward on a double-sided scotch. So we will increase the bonding area and ensure the reliability of fastening without drilling additional holes. Double-sided tape works wonders if the area is large and works "for the cut". True, only crutches will be detachable. The plate with bolts is not so easy to peel off ...

Answer 10

Perhaps, between the back and front metal walls of the case (the front is the one behind the plastic, if there is one, make a metal bracket-bridge, attach the block to it.
Next, why not attach all this to the back wall?
Further, the end walls, in theory Since
the power supply unit is light (by the way, can you give a link to it?), make skids on the side walls, glue them, and the board rises into these skids and is pressed against the lid.

Answer 11

I understand that the power supply is a bare board? You can also glue screws with a countersunk head of suitable diameter and length. And fasten with a pair of nuts for each screw: one under the board, the second fastens above. Only it is necessary to lay an insulating heat-resistant (fluoroplastic?) gasket on the entire board so that it does not break through and short to the metal case.
A better option, if you can get it, is plastic racks for motherboards from old cases (with a skirt and a wide platform; in the figure at the link www.chieftec-ru.com/wp-content/uploads/guide/ustanovka-sistemnoj-platy-v -korpus_1.jpg are similar, only at the bottom there is a mount on the body, which you can bite off). An insulating gasket is still needed.

Answer 12

Show a photo of an open case with a motherboard, the back of the case and the power supply itself. You also need to specify how the motherboard is attached. I think after that the issue will be resolved very quickly.
