2 psus connected into one

[Bajantechnician]

How do i connect two psus in series?

 

plz dont say to not do it....

 

is there any way i can increase the wattage without increasing the amperage?

Thank You

With PSUs, no.

[Aniallation]

You mean 24V with two PC PSUs? Can't do it.

[ApolloX75]

.... why would you want to anyways?

 

Also you can't. They aren't just a battery with a positive and a negative. They are a complex chunk of technology. The isolation transformer and the short circuit protection will not allow you to connect them in series, they will just trip; stop working or worse.

Just get a set up Buck Booster converter you wouldn't need two PSU and why are are needing more than 12V?

watt, not volt

not v, sorry, w

 

need 800 watt

[ApolloX75]

not v, sorry, w

 

need 800 watt

Yeah, doesn't work that way either.

 

 

... sigh. I'll humour you a bit.

 

You can use two PSU's to power one system. It's a simple matter of tying the trigger pins in the main 24 pin plug of the secondary power supply to your "main" PSU to trigger it on when it starts. Then you can use the outputs from the two PSU's as you see fit.

 

It is seriously not recommended.

So If i'm understanding you want to run two PSU's in one system why not just use an adapter like this which will turn on the main PSU and the secondary automatically:

could u make a paint drawing?

Thanks

what i need is the wattage, and more 8 pins

[the ginger gamer]

Why do you need to do this?

Why aren't you purchasing a 800W PSU instead?

There you go @Bajantechnician we used to use something like that back in the day when 600W PSU's were too pricey and you had two 300's lying around but wanted to run some power hungry hardware.

 

It's still not technically boosting your wattage at all, you're just sharing the load between two supplies.

IT would be better to get a new PSU or an adapter from molex to the 8 pins, but that's what was used back in the day if you wanted say a 1000W PSU but they only made 600W PSU you would take that adapter where the first main PSU kicked the second PSU to startup and deliver power for drives, GPU's etc.

[Bajantechnician]

Why do you need to do this?

got a titan z, need 800 watts,

got a 450, and a 350 laying arround

cuz i dont have money......

how do u physically do it?

If you have a titan X I highly suggest getting a Good PSU since poor or bad quality PSU's can potentially kill components. 

 

To physically do this what you do it take the green Power On wire and Grd wire where you split it off so it has a connection coming off of it going according to the Power On and a Grd lead on the second PSU.

Alright...

 

 

See Pins 15 & 16? Black and Green? You tie those two on your "slave" PSU to your "master" PSU. You can do this a couple ways. Either you can tie them to the PWR SW itself or tie them into the 24 PIN MAIN of your master unit. You can cut and strip the wires on the slave, then strip a 1/4" long section of the two on the main and solder them together. This will trigger both PSU's on.

 

I'm also going to put a disclaimer here. I highly recommend not doing this and waiting til you can afford a real, quality PSU.

Seriously, save up and buy a sufficient power supply. It would be sad if you accidentally damaged that awesome graphics card because you weren't willing to buy what you need to make it run. It is a $1500 card, I don't think it is worth risking with a MacGyver approach. Be patient and buy what you need.

[Bajantechnician]

Alright...

I have a 1050 evga, but its 200$, and im strapped for cash.

eh..

um...

no...

 

 

 

i got the superclocked version.

ur price x 2

also, i dont need the 24 pin.

i need 2, 8 pins

[Bajantechnician]

wait.

is there any way i can mod molex to 8 pins?

[Bajantechnician]

bump?

[W-L]

wait.

Yes there are adapters for that, many don't recommend them since the molex side of the connectionscan be overloaded at times if a poor connection occurs, Also for your 450W PSU that will be maxing it out if you have say a Titan X and an i7 CPU, what is your highest wattage PSU you have on hand:
