in my stacker case i plan to stick at least 12 drives. now this system will also be O/C'd as well as having a fairly hefty power hungry card (7950 GX2).

the PSU is a silverstone 650w one and so far is abso fine but i dont want to risk underpowering anything. i have a nice tagan 430w modular psu i want to use just for the drives.

i';ve heard people mention some knid of connector to bridge the 2 psus together in some way.

anyone know what i am talking about?
 
what? i mean i know you need power to both PSUs but afaik, you have to do something to the PSU thats not linked to the mobo otherwise it doesnt give out any juice
 
from searching around here, what i need is a 'relay switch'? OCUK used to sell them but cant see them being sold any longer
 
Do you mean you want to make the 2nd PSU think that's it plugged into a motherboard and power up?

Easy!

If it's a permanent fixture, just cut the lime green and one of the black ground wires next to it from the ATX block, solder and secure.

Whenever you turn on the power to the PSU, it'll switch on automatically.

Have you actually worked out the power requirements of your components, and whether you are justified doing this?
 
well i've just tried this
http://extreme.outervision.com/PSUEngine

and it advised me i need a 798w PSU

not suprising with 12 internal drives ontop of the other components

agw_01, thanks, but i dont want to permanently damage the PSU

i am looking for some device like the one wizardmaxx pointed out

An easier, safer but more expensive option would be to buy a 800W+ psu.

Ok, well just get a paper clip like this...



Turn the ATX connector like it is in the pic, and it's the 3rd and 4th pins from the right.

You could use a small piece of wire and secure it all in place with electrical tape or something.

It's perfectly safe and can be removed easily if you want to use the PSU for other things.
 
send a webnote to OcUK and ask if they have any left.

if not I'll have a look and see if I can find my old one.
 
Dual psus have been known to cause a lot of problems, things like not enough power in the right places, load not shared evenly etc.

Coolermaster produced a switch thing for the stacker which takes 2 psus and i think they sell spare parts now, worth a quick look on their website.
 
Good point Joe.

If I was going to do it, I'd have the master hard disk and graphics card connected to the same PSU that was powering the motherboard.

That way, any fluctuations will be the same throughout the main components and won't cause any problems.

Secondary drives will be fine running off a seperate PSU.
 
Coolermaster's stacker cases come with a bridging lead for 2 PSUs since the case has room for them, can't remember what it looks like though.
