see details in the cpu power supply write
output got so many but i only wan the 12vDC with 9Ampere another one 12vDC is getting 0.5Ampere only.

But in the output got so many wires and colours i dont know which one is 12vDC 9AMpere output.
So how can i know which is the 12vDc with high current?
the output is one got 4 wire to motherboard then another is like 10 or more wires is also connect to motherboard but it is another socket,finally is the IDE for hard disk and cd rom one,
So which one is 12VDC 9 Ampere?
mostly which part of PC are using the 12vDC 9 ampere?

i Can get a DC power supply but quite expensive so wan modify my power supply only for 12vDC high current should be more cheaper

I get this idea is from a hardware seller he want to modify a cpu power supply for me is 12vDC and 8 ampere but the price is RM90 if i buy a DC power supply no need modify 6 ampere is only RM70,the reason that i wan to modify cpu power supply is for save money.
A power supply is cheaper then modify will save more money and get more high current.

Help Sifuu Tell me whic wire is 12vDC which colour is 12vDC.

Thank you

9A you crazy bo? need so many A for what?

i am not using for CPU anymore after modify i only take for power up another thing

probably need to run the full fan speed

black and red for the 12V line, at the molex

if ur talking about the 4 pin molex for HDD and CDROM...the red is the 5v

the 12v gets supplied thru the yellow wire.

try use mr google or wikipedia...more info from that u can get

i am modify it for Car amplifier.with fuse 20A
But i hear from someone he say he tried before but soon the power supply broke and burn.is it true ar???
Or got any idea can protect it to avoid the problem?

Squeezing extra ampere from the PSU will lead to early burn of transformer and switching controller.
build a custom power supply which output 12V DC @ 9A would be more feasible

fren then how to custom it with only 12vDC and 9A?

make new tranformer ??
How to make or ??
A tranformer is it available for DIY,following the ampere that we want ?
Let me know please Thank You

buy this

mod the psu for car amp???

where can get the stuff?

no ideal, btw car DC output already 12V +- i think just need modify fuse can jor but becareful o... don't burn your car.

just to save 10-20 ringgit, you go through all the hassle, and also the possibility of your DIY mod not working and blowing things up.

fwush.

me, id rather just pay the money to get something that is guaranteed to work. besides, in the larger scheme of things, i dont think RM70 is that much.

but bro RM70 for 6 ampere T.T"

sometimes half the fun is in DIY, ie like buidlign a rig or oc...n the anticipation of seeing whether ur handiwork will work or not...of coz dont work then no fun

Well, i've done this project before. Using computer PSU for +5V & +12V power supply. It might be easier to work with if you got the old AT power supply. This kind of power supply can simply be 'on' by toggling the switch. As for the newer ATX, you need to find 'power on' cable and short it to 0V(DC ground). Beware that some ATX need 'dummy load' before can be powered up. Failure to do so may damage the power supply or simply refuse to run.

fren the diagram are show not clear.
Which cable should put to the fuse place and which for the switch.
the +12dc ,-12dc,+5dc,ground is it are there all using for hard disk and cd rom that one cable?
And where you get the stuff like the red and black plug?
Thank You
