Will it be possible to power MikroTik from an ATX power supply?

Question

Do it yourself

Good day to all!
There is MikroTik 951ui-2hnd, the specifications say "Supported input voltage 7 V - 31 V". There was a need to power it from the power supply of a conventional ATX system unit.
If I make such an adapter, will the router work?
What do you need:

spoiler

Есть MikroTik 951ui-2hnd + LTE-модем. Есть три устройства комп+кассовый аппарат+банковский терминал (на островке в ТЦ), всем устройствам нужен интернет. И есть всего четыре электрические розетки (все уже заняты), администрация здания не разрешает использовать сетевые фильтры или "тройники", за установку дополнительных розеток хотят денег. Поэтому возникла идея использовать обычный ATX блок-питания для того, чтобы запитать маршрутизатор.

Answer 1

The main thing is not to confuse the polarity. Theoretically, there will be no problems.
I also found this: 8-28V DC Jack or 8-28V DC PoE to the Ether1 port Be
sure to double-check the box or the sticker on the case

Answer 2

They didn’t connect current from ATX, the main condition is that the piece of iron works normally from 12 or 5V, well, do not confuse the polarity.
At the same time, they hung on the ATX: sven speakers - just because of the lack of holes in the extension cord, the LG monitor - the shim burned out, there was no time to go to another city to buy, a usb hub and something else
. And the routerboard is powered by 5 volts, the input is DC-DC so the voltage is not critical for it

Answer 3

Thanks everyone for the replies, it worked.
The router works fine on 12 V MOLEX, it even manages to boot up and establish a connection before the OS on the computer boots up.
