i have two e5-2670 cpus (non ES) and ecc-r ram

i thought if i put 12V on connectors mobo system will power up instantly

this " Intel Spare Single Node Power" looks like is only or "blade type" connection,

I was planning to make custom chassis with normal atx powersupply (which will be power up via bi-stable power on switch)

switch to green and black cable in atx24 connector and 12V or motherboard (2x 6pin)
