I have 1300W power supply which I am using in about 60% load. I am thinking about connecting a strip of led lights to one of the 4 pin molex power leads.

I also have some other devices I would like to power the same way and I need to know if I can connect all of them to the same lead from the power supply. Lets say led lights and for example two other fans (each of 3 devices have 12V requirements) will it work or I may do some damage this way?
 
One more question, how many times I can split one 12v output. Sometimes to one cable from power supply there are connected 2 HDD's. Can I connect let's say 3 or 4 different 12V devices to the same cable?
 
Yes, BUT...you need to understand how many AMPS the devices will require and how many AMPS the rail(s) are capable of providing. Very likely they are unless you are talking about large power draw devices...

I am thinking about putting out 5 DC sockets on the back bracket so I can connect couple things like:

  • LED stripe lights
    Code: 
    Input Voltage: 12V
Output power: 36W
Current: 3A
  • 16MR halogen lamp (turned on sometimes only)
    Code: 
    These specs are from the power brick
Input Voltage: 12V
Output power: 50W
Current: 100mA (0.1A)
  • Router
    Code: 
    Similar specs as the lamp above
My PSU specs are like so:
Code: 
• 1300 watts of power.
• 170 watts of combined power output (+3.3 and +5 volts).
• 1104 watts (92 amps) combined output power (+12 volts).
• Wide range universal input: 115-230 VAC power for different networks.
• Maximum load capacity of the individual power rails:
• +3.3 V: 26 A
• +5.0 V: 30A
• +12 V V1: 20 A.
• +12 V V2: 20 A
• +12 V V3: 20 A.
• +12 V V4: 20 A.
• +12 V V5: 20 A.
• +12 V V6: 20 A.
• -12 V 1 A.
• +5 V standby: 6 A
• ATX version 2.2.
• EMC-shielded cable strands.
• Active PFC (99%).
• 1x 135mm fan, ball bearing.
• Cable management ports with illuminated.
• Turbo Mode Switch to interconnect the 12V rails.
• Dual transformer layout.
• OCP (Over Current Protection) - Protection against spikes.
• OTP (Over Temperature Protection) - overheating protection.
• OVP (Over Voltage Protection) - Over voltage protection.
• OPP (Over Power Protection) - Overload Protection.
• UVP (Under Voltage Protection) - undervoltage protection.
• SCP (Short Circuit Protection) - protection against short circuits.
• MTBF: 100,000 hours at 25 ° C.

What do you think, if I take 2 molex rails and split them on 5 DC sockets is this gonna work?
