dont mind the poor drawing, idea was to enable 2 PSU running when i press the on button on my casing. maybe 1 PSU is for those blink blink , fan fan, another PSU for hard disk , optical drive ? can it be done w/o harming my motherboard ?

wa,i think its extreamly risky as you could burn down your mb if anything goes wrong, you'll need to find some expert in electrical stuff and get the two psu into one

actually it is quite safe
except there is a niggling problem that
if a power supply is not drawn enuff irt might not work properly
or supply enuff power at all

well it is actually dangerous
cause you are doubling the power supply

it is much safer if you connect a few start wire
just to start the psu
instead of connecting all

Was thinking only connecting the start wires, but dunno which 1 >< lolz ~~

yea , planning to reduce the load of the PSU so that it will prolong the PSU lifespan.

btw thanks for those links =D

@rivoluzione

i have a question.. if we're using 2 PSU, must it be the same??? smthing like SLI? haha

haha no need the same lar..different oso can..
go for truepower for mb, and chapalng for bling2 stuffs..

you could use the primary PSU which has got a more stable rail for the CPU while the second one for the rest of the stuff like optical drive, fans and lightings...

you just need to add another POWER ON/OFF button for the second PSU because once you shut down, there's no way it can be done the same to the second PSU.......therefore you'll need a manual button to ON or OFF the second PSU

actully can just use a paper pin to short it right?

yep...green wire and any ground ( black wire ) will do

You can also use an AT power supply. Much much much less wiring...

Aiya just go buy the 2 PSU converter lar. What it does is connect ure 2 PSUs together. Then it works like 1 PSU. All it does is start the other PSU together with the main PSU.

no need 2 PSU actulally to power up the bling2..just modify the and u can use as many as u want to connect the bling2..but beware of shortcircuit..huhu...i think its better than using 2 PSU,as it will consume too much electrics..

wanna know what's the minimum W required to power up the rest of the stuff like optical drive, fans and lightings...

if using those 5" bay psu to power it up, sufficient ka if using 2 standard psu size --> will have to change casing

like this



ya, ya, ya, i know it's for vga, just wanna know

hmm ... juz the idea of it lo ... hehehe ^^ knowledge ma

i using tht thermaltake drivebay PSU to power up water cooling pump, 12v fans and also CCFL, i also power up my 1950XT.... not recommended for HDD as it dun have 5v rail i think....dun dare to power up HDD using it.

where actually can we get the 2 psu converter?How much izit?and..last but not least..how does it looks like?

actually no such thing, only ATX casing come with built in converter. so no need to find it at lowyat

Got lar. Those server parts shops will haf it.

wahahaha!!!i've created my own dual psu and working quite impressive as one psu for my 6600GT and fans while another one for the rest

abit of soldering and wiring can do the job. just connect the green and black wires parallel to each of the 20/24 pin socket, then connect one socket to the mobo. when you switch on the power, both psu will run.
