Yes, it use 2 power cable.

The Lian Li PC-A10 casing do came with a special internal cable that link 2 PSU(s) together.
By pressing the casing power up button, 2 PSU(s) will start up together.

cant understand what ur trying to tell... but anyway..see the pic above??the cable with many wires..u connect it to ur ori psu..the second one with only 2 wires (green and black)...connect it to ur secondary psu..so switch on the power for the ori psu only la...when u shut down..both of ur psu should shut down together lor...

If you want to self make 2 PSU then ...

You should have a main (1st) PSU which connect to motherboard and the 2nd PSU which connect to your graphic card, HD and etc ...

If I not mistaken (please correct me), you should switch on the 2nd PSU before the main (1st) PSU.

Since the 2nd PSU is not connected to motherboard, no way you can switch it on. You should make a wire connection from GREEN to any BLACK at the PSU's socket for motherboard connection.

After you have done that, to switch on 2nd PSU, just switch on the power outlet at the wall that connected to 2nd PSU. It will start up.

Where else the 1st PSU, just switch it on by pressing the power up button from the casing.

TQ guys for informtion..

sofware in pc to show successfull combination both psu???

how???

if you see my pc runs when i take dat photo...

oo like dat...

i dun feel nutin b coz i ve already use 450 true power , so i just try to use 2nd psu for my gc...

using 2 psu is good for user have one cheapo psu but he use graphic card that needs power from molex...

so you can use one psu for mobo , hdd , cd and dvd..

2nd psu is for graphic card or fan , anything....

furthermore before i have using CoolerMaster 450watt true power , i have using cheapo psu that doesnt come with graphic card 6 pin molex for my MSI nx7900gt...

you know what happen when i using that cheapo psu???

its still can boot but it will hangs like crazy!!!!!
hehehehe... just my 2 cents

actually 2 psu doesn't mean 300+300=600 ...one single psu with juz its own total power...the reason to use dual psu is to supply power to some part of ur hardwares in ur rig when u have too many hardwares in ur rig and ur psu can't supply enough for all of them..for example..

1st psu (300W):
-master hard disk.
-Dvd drive.
- mobo

2nd psu (300W) :
- slave hard disk
- Graphic card

ok..if ur 1st psu (chapalang) cannot support all the hardwares above...we need to divide some hardwares into two group..so each psu will supply enough power to each hareware
