Great way to get a lot of USB ports.Read more0Comment| One person found this helpful. Uses 5V rail of PSU New (2) from $150.00 & FREE shipping. The power supplies of the time could provide a hefty 5v, probably enough to power all of those ports adequately. Also, I am not aware of how the power is managed in the USB OTG ports and although I think nothing bad will happen, I take no responsbility if it does http://webstrategy360.com/power-supply/250-watt-atx-power-supply.html

I moved the binding posts further apart so its easier to connect wires to them. http://webstrategy360.com/power-supply/bad-power-supply-symptoms.html To learn more about Amazon Sponsored Products, click here. I ask because it does not have any chips on it.

I found this instructable while trying to find out if USB splitters require circuitry.

Do you know if USB hubs require controller I started to guess that those holes in the PCB and the hole in the enclosure were to solder the connector for an external power supply. Atx Power Supply Mods

If you're a seller, Fulfillment by Amazon can help you increase your sales. As far as short circuit protection, all the atx psu I have used have some sort of protection, even the cheap ones, be it that it would have to be a I would be surprised if the PCB traces could handle that much current though, they would likely burn in half, so maybe splitting it up, using three 5 port hubs might this contact form I've traced the failure to two causes: one failed because of plain bad quality electrolytic capacitors, the other from a failing coil.

Evidently, there is a lot of GOOD engineering, but directed

I opened the case and right next to that unexpected hole, there were three holes in the PCB without any component inserted on them. Computer Power Supply Mods So I'll probably have to beef up the feed traces if possible. A computer may work but is not really a stand alone solution. [Jeff] and the crew over at Make Lehigh Valley ran into this predicament.

I plan to run 9 per hub, and I have the exact same hubs.

The horizontal spacing is 3/4" and the vertical spacing is 1". The outside stays cool enough to touch.

Mine is a very common 1157 brake/rear light bulb, that pulls enough current from the 5V rail as to keep the supply happily running at do I need to be cautious of same?

Thank you for your time.

It takes 2a for fast charge to happen in modern devices

Thanks :)

The device will only use as much current as it needs. I would probably cut the traces on 1 & 4 and solder in some diodes to isolate each device, though I don't think it would be required. You would be better to use something like a LM2596S DC-DC Constant Current and Voltage Adjustable Module, which gives you something like 1.2v-30volts adjustable and up to 5 amps output with navigate here Anyway, you can see that there is the same ammount of = power available from both PSUs at 5V, but this power _has_ gone down proportionally to the total Wattage of

Are the two USB ports current limited in any way?The USB standard specifies 500mA for compliance. They were putting on an Adafruit Trinket class and needed a USB power supply to power all of the Trinkets that were going to be used.
