Can I use 2 psus in one rig?

[Martin 71]

Hey, I'm really stretching my 500w to the limit... Can I also use a 350w in unison with my 500w? like plug the gpu into the 350w and the rest into the 500?

Technically yes,
Practically why?

just go to a power calculator site and check out what you require, then buy a new psu that meets or exceeds that recommendation.
Do you have space on your case for 2xpsu's?
think of the extra heat your going to generate, plus your going to have to rig the secondary psu's switch to the main psu so it comes on at the same time, lots of hassle and engineering to consider
Thats not a 'no,dont do it', just a pointer that its not very practical

They likely will not output exactly the same voltages, which could be problematic. Much safer to buy a singe good PSU that will easily handle your needs.

I got two of them to work... thanks.

 

[Motopsychojdn]

Well done man, but seriously,

BE CAREFUL keep an eye on temperatures of both units and imo unplug every night before you leave it unattended,

yeah I was pretty scared when I went to turn it on... It seems okay... but I don't like the look if this... there's stereo cable connecting the second one to the mobo... and It's just messy... functional, but messy... I'm ordering a 750w as soon as possible

 

[dndhatcher]

Just in case...

 

[Martin 71]

Ha ha! the first time I booted it up, I got to the back of the room!

 

[Motopsychojdn]

Lol, I'm reminded of my younger days hehe, stereo wire got used for so many 'projects', glad it going well man, hope your new psu gets here in time

[Motopsychojdn]

[Martin 71]

mmmhmm... it was only hooked up the the 5850 and my fan, and both are still on the 30 day return policy... and then the second psu surged... im just glad i didnt hook it up to the mobo or the cpu!

 

[Motopsychojdn]

At least you've learned (relatively cheaply I might add) the capricious nature of electricity,
without personal injury or burning the house to the ground
GL with the Rma man,

Ty for B.a. man, I hope you learned a valuable lesson
and I really hope you continue to tinker, think about things and try improving them, just be a bit more careful in future
