How to turn on rig without power button?

[theegle]

So I am in the middle of building my first ever computer/rig and I am wondering how I am going to turn it on? If it is of any help I am using the B75MA-E33 with the GX II PSU and a 7950.

you need to short the power switch pins on the mobo's headers. Look in the manual. It will be in with the hdd led/reset switch pins

After that, look in the bios settings for one that lets the computer restart automatically in case of a power outage

I remember being terrified of being electrocuted when I shorted my power jumpers...
Hehe, it was fine and kind of enthralling.

Helpful hint when dealing with electricity - make the connections, and then connect the power.

You can also buy cheap switches on ebay that plug right into the motherboard head pin.

You could always use those jumper pins you place on the pins of the hard-drive, they should reach. Should keep it tidy too without a cable. Just a suggestion

Screwdriver all the way

If you don't need your motherboard than you can use an PSU activation connector to turn the PSU on.

Screwdriver absolutely!!!!!  Occasionally I use my keys if I don't have a screwdriver handy.

You would have to put it on then quickly remove it every time, Otherwise the mobo would just continuously turn on and off.

Ethernet wake-up is a good method to power on, and IPMI power-on is even better, but the latter is only supported by few boards.

you can use a paperclip and bridge the green cable to a black one, on your atx 24pin psu cable ( green color is for the on/off switch )

then you just use the switch on the back of the PSU to turn off and on.

hope this helps.

^this. its very simple to do. find a peice of scrap wire, trim it down to be about 0.5" long, strip 0.125" of the plastic sheathing at each end, pinch/fold it in the middle, and jam in into the 24-pin MOBO cable so that it creates a connection between the green and black wires.

if its snug on its own great. if not, a dab of glue, or a ziptie/electrical tape wrapped overtop to hold it in place is all you need. its not a high voltage or anthing, so dont put too much though into it.

I always set them in BIOS to "FULL ON after Power Back", it also ensures that after a blackout the miner will turn on. Then I also enable WOL and Power On by RTC alarma and set it to something like "everyday 12:00:00 PM", so I don't need to come close to the room with miners, even if for some reason they turn off, they will be back somehow.

This way I can go on business trips for whatever long I want and I don't need to worry about miners going down (except for PSU failure, but that's different story).

Yeah good point, I would just go with the BIOS method :p

To sum it up, use a screwdriver and go straight to BIOS and set it ( under power settings ) to reboot from power outage, then SAVE SETTINGS.  Now you will be able to just remove/plug in to start it
You could check the case you are putting it in and see if it has a button.  Another solution is steal the reset button from another case.  Good luck with the mining.
