Q: Where are the power switch pins?

Registered UserI’m custom building a PC. I’m using an MSI Z97 PC Mate motherboard. The big power supply is an EVGA 430W. It’s all plugged in, and I hit the switch but it doesn’t do anything. Both JPWR 1 and 2 are plugged in. A photo tutorial (pictured in this link) mentioned some “power switch pins.” Am I miss...

 
Does the PSU work? Short the green pin on the main 20/24-pin ATX connector to any of the black connectors and see if the PSU fan spins up. If it doesn't, there's a problem with your PSU and you'll need to replace it.
 
@DragonLord Can you explain to me how I would short a green pin?
 
Take a paper clip with exposed metal, hook one end up to the pin with the green wire and the other to any pin with a black wire. This is perfectly safe and your PSU should turn on when you do this.
 
@Dragon So i have to take the connector out, find the hole corresponding to the green wire, then attach a paper clip from that to any one of the receiving holes, then turn on the power? I won't get electrocuted?
 
No, it's just a low-voltage signal for the PSU to turn on. Yes, you do need to remove the main ATX power connector from the motherboard.

@DragonLord thanks. the connector is a pain in the ass to connect/disconnect. doing it now
Edit: is this how to do it? then just flip the switch
 
No, not to the motherboard, but to a black pin on the power supply side. cdn.instructables.com/F7F/I9FX/H130PCQR/…
 
ahhh.
i see.
is it necessary to do this little thing no matter what build?
 
Your PSU should turn on once you do this. If it does not, then something is wrong and you need to get it replaced.
 
@RegisteredUser No, only to test the power supply.
 
1:50 AM
alright
nice.
fan is turning.
 
Okay, PSU is working.
 
yup
i will now shut it off, take out the paper clip, and plug it back into the mobo
 
Once you have it put together, show us some pictures of the setup, including the wiring for the power button to the motherboard, so that we can determine what might be wrong.
 
Sure no problem. I will now do what I said I would do above.
alright, for some strange reason, after I plug the 24 connector back into the mobo, and I turn on the power supply, nothing happens.
@DragonLord the mobo was purchased open box
any help?
 
Hmm...
 
2:03 AM
_
 
I'll need to see some pictures to determine if there's a hardware issue.
 
sure.
what type of pictures would you like to see? @DragonLord
 
The connection of the power button to the header on the board.
 
isn't that part of the case? I'm not that far in yet.

with your comment, i'm assuming the following image:
 
@RegisteredUser That's returning a 404.
 
2:07 AM
my bad
@Dra
@DragonLord is this what you need?
 
@RegisteredUser No, I'm looking for the part of the motherboard where the power button wire is plugged into the board.
 
so the 8 pin thing?
sorry to frustrate you, i'm a first time builder and i have no idea what i'm doing
 
Not that connector. The connector where you plug the case's power button wire into the board.
 
not JPWR2
ok
the case I haven't even unboxed yet. brb
 
@RegisteredUser That's CPU power.
 
2:10 AM
right, ok
@DragonLord it's a source 210 case.
 
Okay, I think I understand what's going on. Drafting an answer now.
 
@DragonLord thansk for all your help
 
2:26 AM
ok so the one coming from the power button is a thin but long cable and it's 6 wires built into one. Where do I plug this in? @DragonLord
 
@RegisteredUser Plug it into JFP1. Be sure to follow the instructions as you need to get the pinout right.
 
thank you.
@DragonLord how can i tell apart postivie and negative connectors?
 
Post a picture of the connector from the case next to the JFP1 header.
 
2:42 AM
You'll need to see the motherboard's documentation for the pinout of the JFP1 header.
 
do you have an instant messaging thing of some sort so i can send images to you faster? uploading to imgur is too tedious
i have snapchat
 
Sadly not
 
Use the Upload button in the chat interface instead.
 
lol my computer cant take pictures :)
 
2:48 AM
On JFP1:
Power SW to 6 and 8 (doesn't matter which way, the pins are just shorted when you press the power button).
Reset SW to 5 and 7 (again, doesn't matter which way).
HDD LED to 1 and 3 (the red wire should be in 1 as that's the + connector).
+P LED to 2, -P LED to 4.
 
Thanks!
 
You can ignore JFP2.
 
It can take a bit of dexterity to hook up the pins. Be careful not to damage anything.
 
I managed to get it in
 
2:51 AM
Alright, it's time to turn it on. Press the power button.
Once you confirm it's working, turn it off and secure the motherboard to the case. Be sure to use the standoffs.
 
NICE
brb taking pictures of the joy
it works.
 
3:14 AM
For reference:
Answer updated. Once again, be sure to put the standoffs in the case and secure the motherboard to them.
 
sorry, went away for a while
