Am I missing something? Male/female connectors on PSU

So I ordered a "female" ATX switch. My goal was to plug in the PSU end of a 24-pin ATX connector into a physical switch which mimics the "motherboard end" of the 24-pin connector in order to start the PSU. They sent me what I think is the male end that would plug into a modular power supply. They are telling me that the "female" connector is the one where you put all the pins into and I didn't know what I was talking about. I'm like, well, the "female" end then slots into the "other female" connector on the motherboard then?

Have I been wrong about this my entire life?
 
male has pins, female has holes... wtf are you even talking about though? post a pic...
 
Male-female always refers to the pins, not the body. The side with female pins is called female. In the case of molex mini-fit jr connectors (and many others), that happens to be opposite of the connector body.

I will. I'm not at home right now but I can get some pictures later. Modify.com is giving me the runaround. They gave me a connector with pins and are trying to tell me that it's the female end.

these are femal pins(holes):

That is what I ordered. I asked a lot of questions and it says it is a 10 pin female molex connector. I thought it was just a incorrect picture.

That was what I thought I was ordering just with a 10 pin connector instead of a 24 pin connector. They both say they are female molex connectors.

I am trying to power one of those AMD bc-250 boards which doesn't have a traditional power switch. It only needs an 8-pin GPU connector to run. So I just need something to turn on the power supply to utilize the 8-pin connector.

I will probably end up just cutting the connector and soldering the wires off the switch myself directly into the 10 pin connector on my power supply. Just a PITA.

That's a male connector, the pins inside are male, not female. That is what you would plug the power supply into on a motherboard.

In case it wasn't clear, I'm saying this is the connector you want. Or a 20-pin one if you have an ancient psu.

Does it have a pinout for that 8-pin connector? It may be atx with all the legacy signals stripped out, in which case it would still have power-good, etc, and using an 8-pin power connector could damage it.

Nvm, I found one, you good. (y)

if your just trying to use a psu to power something, short the green wire and a black wire to power it up. you could use an old case power button to do what you want too.
 
So I'm trying to use a Flex FSP FSP500-30AS. It was the PSU in the Ghost Canyon NUC. It's kind of weird in that a momentary "case switch" style power button won't work because the PSU has to stay shorted in order to stay on. A momentary short doesn't do anything other than blink the LEDs and spin the fans once around. That's why I was trying that style switch from moddiy.

I might just buy something like that and reconnect it myself.

Here is the connector from my PSU that I'm trying to adapt into a switch.

That's normal -- if you don't leave the paperclip in a standard atx psu, it'll shut off, because it needs the signal from "the motherboard" (clippy) to tell it it's ready to receive power.

You could get that, and/or a minifit pin removal tool, and swap the pins. Or you could get a long jumper wire and cut it, then solder a switch to the ends.

Then you just need to plug it into the correct holes on the empty connector.
