ATX (bench) Power Supply Outputting Voltage but not Current

<< < (3/5) > >>

GerryR:
Just thought I'd mention that you are going to fry the 10 \$\Omega\$, 10 W resistor.  Rule-of-thumb is 2-1/2 times the power being "consumed" by the resistor for a wattage rating.   :)

@Mindcrime
Tried a known good PSU (a Dell NPS-210AB I pulled from a NAS), and got the following results:

- Battery Charger: 0A
- Phone: 0A
- Load Resistor (10 Ohm 10W): .5A
- Go-Tcha (Pokemon Go Accessory): 150 mA

I'm guessing the top 2 REQUIRE handhaking?
Can I add a chip/circuit to do this handshaking? I'd love to be able to charge my phone at 1A+ (OEM charger is 2A) on the 5V Sb.

@GerryR
Oops.. Miscalculated that (yeah.. It's pulling 14W atm) I'll probably add another 10W resistor to bump up the resistance to 20 Ohm, which should drop it to 7.2W at .6A

ledtester:
The "handshake" could be as simple as placing certain voltages on the data lines.

See this Stackoverflow answer, for instance:

Few things:

* You might want to reconsider using actually not worthless electronic devices as load resistors, while unlikely with ATX supply, you probably don't want to accidentally burn it.
* Please do put some kind of fuses on the lines. PC PSUs can put out tens of amps on the 5V/12V line and you probably do not want to weld something accidentally with it.
* There is no real standard on how much/little load you need to put on ATX supply to be stable so that's basically trial and error part, but I'd at least double whatever I found to be a minimum just in case
* Have you seen ? This + ATX power supply is easy way to get features useful for lab power supply, like the current limiting.

FrankvHoof:
So, I tried hooking up some voltage dividers to the D- and D+ -pins, according to the StackExchange-Link (2.0V on D+, 2.75 on D-), and still got nothing..
I'm done.. All other outputs (both fixed & variable voltage) work, so I'm just going to keep the USB's unplugged, I'll have to charge my devices another way.

@Xani, all outputs are fused on the back of the front panel. Furthermore, I'm using a boost-/buck-DC-DC converter for the variable input, which has built-in (variable) current limiting, so if I expect to need it, I'll use that output.
