Good morning everybody
Tony, a french newby in the community, hope I'll help people here but to be honest my limited knowledge will make me ask more questions than answer them.
Anyway, what brings me here is I just bought/built a desktop computer for the first time of my life.

The configuration is the following :
(purchased together already built to a friend to save ££)
- Zalman GT 1000 for case
- Sabertooth Z77 as motherboard
- Enermax 1000w 80silver (didn't need 1000w I guess but was already in the case)
- Intel i7 3770

(purchased after)
- 2 x 4Go Ram GSkill
- GTX 660
- 1 x SSD kingston 120go
- 1 x 7200rpm seagate 2To, 3.5''
- other previous hard disks 3.5'' I wanted to plug, waiting the issue to be solved

All of that mounted as good as I can,
with just the SSD alone I could start the PC and install my windows 7 on it,

yesterday night I moved the pc to its final destination, arrange cables, added the new seagate 2To and another one 1To that I had before as external and wanted to convert as internal.
Turn on supply, turn on the computer, zium ! nothing. back LED of the supply is RED, (which according to the web means PSU security mode).

Of course I didn't understand anything, but after many minutes complaining at my cat for that issue, I just unplugged the 3rd hard disk (so just keeping SSD + 2To) and miracle everything started.
My question is the following,
I totally dont understand all the plugs available at the power supply, the 12V5, 12V6,etc...
I just knew enought to power the mobo and the graphic card.
I used the power cable that has all those "hard disk plug" one after each other to supply the SSD, then the 2To then the previous 1To,

Should I make this supply cable pluged to another 12V rail of the supply box ? Is it a problem of master slave hard disk ? Is it impossible to feed 3 hard disk on the same cable ?
I will make other tests tonight but dont want to screw things up and this red light issue scared me a bit...

My knowledge is low but I really thought that having a 1000W power would be able to almost supply my entire neighbourhood, coffee machine, etc :)

I know that as I'm struggling I should have bought something already working but I would never learn anything

Thanks a lot for the support,
Cheers
Tony

Thanks for the reply !
Good question, as far as I can remember yes when I installed windows it was with only the ssd.
But it is a pb to have done like that why does the system support the 2to added that was not during windows install, but does not accept a third hd ?
