Power up switch with my pc psu?

[Pinguineter]

Hi !

Someone knows if i can connect a tp-link switch directly to my psu?

 

I took some pictures so they can see the voltages from my switch and pc psu.

TP-Link PSU output: 5V 0.6A

Thanks

Technically? Yes.

Should you? No.

And finally, why would you want to?

It would not work because your switch needs 100-240V AC input, whereas your PSU outputs 12V, 5V, or 3.3V DC. At any rate, why would you want to do that?

1. Thanks
2. Why?
3. My router lan ports are full and I do not have more 220v outlets nearby for my switch and I do not want to spend money on that.
Plus, fewer objects on my desk or nearby.

It will work, your switch needs 5V DC with a rated current of 0.6 A, which is no problem for your PSU. If you want to go ahead with this project and have some DIY experience, I would recommend using a 4 pin molex adapter (it has 12V as well as 5V, so measure which is which before connecting anything) so you can detach it any time you like and don't damage your PSU's cables.

Oh i won't be using my 220v adapter, i will use the 5V line directly from the PSU.

Switch directly to PC PSU 5V and Ground cables

=====================================
See image = 5V 0.6A output

Great, first I wanted to ask why I did not want to ruin anything.
I have some molex cables from graphics cards adapters, i will use that.
Thanks so much ^^

Use a power strip.

1. Yep.

2. Potential fire hazard if done incorrectly. Not to mention every time you turn off your computer it'll lose power too.

3. That's why power strips exist. Cluttered areas can be cleaned.

I would but is too expensive, i live in Argentina, inflation here is a problem and sellers take advantage of it. 
Ultra cheap china power strip with bad plastics and cables cost $800 ARS and it should be $200.

what? no it's 5V input

In the end, it all depends on your skills and whether part of the reason for that DIY idea is also learning something/having fun. You have to be careful to do it correctly (polarity, no short circuits, proper insulation, etc.) and also remember that any failure of that switch will probably not be covered by warranty. Like any DIY stuff, what you do you is at your own risk.

Personally, I would buy a power bar with more sockets and spend some time for desk cable management to make everything look good, even though I have the skills for the rewiring project.

You could instead power it via USB 3.0, but i'm unsure if it needs to recognize a device using the Data+- wires to deliver 600mA or up to 900mA

Im having fun actually HAHA, i did some soldering in the past, i know a bit. Thank you for warning me of the guarantee, also the period has already passed. And power strips are expensive here, ( I have money to buy it, but I do not think it's necessary.)

That's a good idea too, but im using my 4- 3.0 ports for drives and stuff and i only have 1- 2.0 port inside, would not give enough power, right?

USB 2.0 is rated at 500mA maximum, I wouldn't risk frying that port since the switch is a 24/7 device

You also can get a small USB charger and use that to power the switch, really don't recommend using the PSU to do that unless you actually do it properly and not duct tape it

for example
https://www.amazon.com/Chanzon-Female-Connector-Security-Adapter/dp/B079RCNNCK

Something like this to wire the 5V wires onto, and then find a hole in the case where the connector would peak outside slightly and then glue it in place (or a tight fit)

https://www.amazon.com/Valley-Enterprises®-2-1mm-5-5mm-Adapter/dp/B00DX72UXW

and use that to connect it to the switch

I got confused because of the input stuff  now I see what's going on
