How to run internal Hdds from secondry Psu

[xxxhomie21]

So here is my problem
My Psu zebronics 600w became faulty because of which:
my system hdd started hang and stuck at red light(Hdd Led) when i'm trying to run all components i.e. 2 Hdd WD 320 gb, Seagate 1tb-(boot drive) both are 7200 rpm drives and gpu 560ti (power hungry)

Till yesterday If i disconnect wd Hdd my system can run smoothly

But today I have to unplug my gpu to run my system

I can't afford another psu right now
so i thought to run my hdd's from secondary psu spare one which i have from my old pc

i've tried that by reading on internet, the psu runs but hdd doesn't rotate
I've sorted green wire with the black wire next to it


plz!!!!!!!! help

It cannot be done without a (questionable) power supply adapter that allows you to connect both power supplies into the main 20+4 motherboard power connection.

Is there any other way

Buy a new PSU.

But in web people are doing this with no problem
Is i'm doing anything wrong

Why are you so sure that it is the PSU that's causing problems?
It is more likely that your hard drives are dying.

Hi

according to GeForce web site a good quality 500 or 550 Watt PSU would be ok for the GTX 560TI

I would recomend getting a good quality PSU asap
I would also test the WD hard drive to see how much power it draws in case it is faulty
I would not expect a normal 3.5" hard disk to draw much power

certainly unless you were playing games the graphics card would not be drawing large amounts of power and taking the PSU over its safe limit.

The load of one HDD on 5V & 12V lines on a PSU may not be enough to enable the PSU to start up.

Bcoz i'm running my Hard drives on the same psu they run smoothly

while it can be done in theory its not something you want to do...
as you can end up cross contaminating the motherboard with voltage from both psus if 1 or both of them have unstable volts.

if your system cant boot with all the peripherals attached, but boots if you leave some out. then the psu is either dying or seriously underpowered for the build.
either way it needs replacing if you want to run your system.

like i say it can be done but its not something you should do...

IT boots Up but after some time starts hanging like a hell

There are 6 people (so far) participating in this thread.
5 of them suggest "Buy a new PCU"
There is one holdout.

What will this one holdout do?

This sounds like those fatal cases of folks injecting themselves with silicon for augmentation because they can't afford a real plastic doctor and saw this youtube... [gasp!]

 

[xxxhomie21]

Sry for asking too much
I'm worried bcoz if I bought new Psu And then came to know that the hdd was culprit

See. THIS is a problem. So even if you get this 2nd PSU working and powering your other peripherals (HD). Eventually those components powered by the faulty supply is gonna die. The 2nd PSU doesn't come in and take over the show, he's just holding on the broken part of the bridge, then more of the main bridge start to crumble.

If we are on a 15 minute count down and I just need to get the system started long enough to disarm the "device" otherwise humanity ends, OK, I would do something, but the weather is nice right now for street boarding (watch the news?), leave that PC and go outside!

Now there is a possibility one of your components is having a SLOW thermal run-away, and not fault of the PSU (am grasping here). A component is heating up and the hotter it gets the more power is consuming. But if you have to ask, the only way to troubleshoot this is to swap the components. The electronically-inclined can use a hand-held thermometer, a Digital Voltmeter, figuring out which rail of the PSU is being taxed etc, not for plug&play folks.

yep monitor your voltages. see if its actually the psu thats the problem.
theres lots of reasons a pc will hang. a psu is just 1.
