Dual PSU

[trevnel909]

Here is my problem, I'm upgrading my PC and I'm gonna need a bit more power(from the power supply).

 

Solution?

What I would like to do instead of buying a brand new PSU and giving away my old one, is buy another cheap PSU and use the old one to power my drives, GPU, water cooling, and anything else I can ( besides the motherboard)

and use the new one to power only the motherboard.

Could this work? Why/ Why not?

Is there another way to do this without buying an expensive new psu?

 

 

Thank you, Trevor

Interesting question.  How will you get both Ps to turn on at the same time?  where are you going to install the second Ps?

Are you trying to go Austin mode from scrapyard wars? I mean, he got it to work....but just don't do it.....ever.....

I mean people have done it but it isn't exactly recommended.

It can work, but you have to mod two pins of the 20+4 pins to let them start up at the same time.

But I dont recomand this at all,   how much power you desire? How much you can spend for a new one?

Please post a partslist, maybe you don't need more power.

 

EDIT: You have to, connect pin 7 and 8 on both PSUs and for sure one of these two completly  in

it will work

you just need one of these

Spoiler

but i recommend getting a single psu anyway

1) does your case support 2 psu?

2) the space it takes up tho...

yes but how would he get power to it? drill a hole in the panel for the power cable to go in? lol

Dont question it, cut a hole in a side panel or something

No. Never buy a cheap PSU. Buy one decent one with enough watts and be done with it. Killing your PC, or even setting your house ablaze, with a shoddy two-PSU solution is more expensive than a quality PSU.

Two wrongs don't make a right, so no, don't run two shitty PSUs instead of one solid one. There are plenty of inexpensive great units like the 750W EVGA B2 that should power your system without trouble.

P.S. I had this PSU in mind for the second one.

 

I currently have a corsair cx600

Well, the cost of getting two proper Independent / DC-DC regulated PSU to handle the crossload scenario that these setup tend to be and a case that supports a dual PSU configuration, you may as well as get a proper single PSU to power your system anyways.

Can you provide your system specification that the PSU will be powering?
