Theoretical Power Supply Question

[brendano257]

I'm going to be going without my Corsair 750TX for a while due to a defect.
In meantime is it possible to run 2 psu's to one system in order to meet the power requirements. I have my pc down clocked to fit into my Ultra 400W at the moment.
But could I have one PSU powering the 8Pin cpu, and both plugs on my 260GTX, and another 400W powering the 24Pin MB connector and peripherals? One connector from each is connected to the MB so that it will be told to turn on. Is that connection necessary or can one simply run the graphics card without any other connections, or am I crazy and this is a bad idea period?

(My 750TX started spitting sparks on start up.....that's why it's being RMA'd if you care, there was no damage to any other PC components, I am sure of this, so this would not be a problem.)

Just a wondering question, I'll survive with or without but it'd be nice to know. thanks for any help!

Watch out for good grounding, should work

I don't know if I would try that. I would probably be more inclined to have one powersupply run just the mobo, and then the other to run the extra stuff.

Though personally I'd just wait.. O hell I can't tell a lie, I'd try it to lol.

Run a wire from 1 psu mounting screw to the other psu

Run a wire from 1 psu mounting screw to the other psu

Does this just ground them both properly?

Thanks for all the quick replies.

So If I had one PSU just run the Graphics card would it still know to power up when the PC started? (The other would get the mobo and peripherals)

 

[the last resort]

as long as the GFX cards are receiving power they'll start. They don't care where it comes from.

You'll need to run a jumper from the green " Power On " wire, and a ground from one 24 pin connector to the other in order to get both units to startup together.

To go further one what Dell said. That would be the way to do it. You can get plastic clips that will hook onto the wires, that will connect both wires together. Their like clamps I used them a lot in rv factorys not sure of the actual name of them.

Or I'm pretty sure you could just jump the switch manually as soon as you turned on your mobo powersupply. But if you can find the clips at your hardware store to me that would be the best and easiest option.
