Sometimes its best to put the rig together outside of the case first to make sure everything works. Then install it in the case. Sucks when you have a faulty component and have to pull it all apart and send something back.
sound advice. i got full of myself (thinking "i had done it before many times; it's going to be okay"), so i went ahead with full assembly...and nada!
Yeah, this might work..

Hopefully just a DOA power supply. I know mine shipped from Amazon last month with absolutely zero protection in the shipping box, and not much of anything protecting the PSU inside the retail box.
thanks for the link. will try that. i hope nothing is DOA and that i've made a mistake somewhere. we'll see...
Just use a paper clip to link the green with a black wire, Also make sure you haven't put the cables around the wrong way on the PSU because they do fit both ways. another thought have you plug the front panel power button in right? also could be the cpu or socket.
will check the ATX cable(s), sure. thanks for mentioning that. i tried my best to figure out which side attaches to which component (PSU/MB), but maybe i've made a mistake somewhere.
yes, i have plugged the front panel power button cable. there is a picture at the top of this page where i highlighted the two pins i used to connect that cable. it's a bit confusing though as it shows three GND connectors. i will also have to try testing the power switch on the M1 to make sure it is not the source of the problem.
The 24 pin would lose its sense function if reversed (pin 20 is intended for the PSU side), but it's not vital to operation.
Apart from that you can't actually physically plug these things in incorrectly. The sockets are all keyed with unique combinations of square/hex holes that stops any short circuit.
yes, they are hex/square-shaped sockets/plugs, so it's not possible to plug them incorrectly. i'm still not sure if it matters which end connects to which part though, but i'll give it a try.
thanks everybody for helping me.
