I have two PSUs (a 500w and a 600w seasonic). Is there an easy way to use both of them? (my CM stacker can take 2 PSUs). I have done some googling and there is talk of soldering wires and risk of frying stuff, so i thought i would ask. If its gonna be a real hassle i might just buy a 1100w tagan. I bought this 600w seasonic last week without really thinking about it... i just thought i would wack them both in the case and away i go. doh !
 
I want to fill the case with hard drives (12 eventually) and also have the option of Sli/crossfire. I posted a week back and we came to the conclusion that peak load on startup with that many hard drives might not make a single PSU happy.
 
just motherboard controller... 2 in raid, 2 on IDE, 2 on SATA. But i have more IDE drives i want to stick in the case.

Buying this 600w seasonic was a mistake then :(

What makes you say it's a mistake? Use the 600W Seasonic for the main system and the RAID array then use the 500W Seasonic for the other drives.
Click to expand...

because others in this thread are saying that its a bad idea.

I have a cable that came with the original 500w PSU that has a female connector running off the 20+4 pin thingy that plugs into the mobo... there are only 2 wires on this connector and they are green and black... what is this connector?
 
I only mention that cable as Jeantech (the make of the 500w power supply), call this a "20+4 main connector -- 20-pin and 24-pin dual use main connector"... the female connector on the green and black wire could take a male 24 pin connector off another PSU (although i certainly am not gonna try this without knowing what it actually does - DONT WORRY) :D
 
yeh.... but that cable is all i need to run two PSU's right?

one of the PSUs will plug into the mobo... the other into the female socket on that cable (with the green and black wires) to turn it on at the same time as the other PSU... then i can use the second PSU to power drives??

im sure thats what this cable must be for... because i have googled and seen people make there own cables out of small bits of wire that look like that cable in the image.
 
I thought so. But i certainly didnt wanna try it before i was certain.

Then that leaves the only question...

is it ok to use this cable and run two PSUs? Others thought it was a bad idea but i think this was because of talk about me (a complete and utter electrical retard) contemplating doing some wiring myself hehe.
 
yeh thats the cable i got... although i thought that came with my PSU rather than my case... but to be honest i have so many old cables lieing around i dont have a clue where they are from :)

im just gonna power down now and try it :p
 
lol... i would... but i really cant be bothered :P

a64 4000+ is at 27 celcius.

its good enough for me... cant beat a good cable mess !! ;)
