need help with 2 motherboards using 1 power supply

post #1 of 10
Thread Starter 
Hello all

I have been searching the internet for articles, plans etc on how to power 2 x motherboards using only 1 power supply.

The reason i want to do this is because i go regularly to LAN's and enjoy gaming but would also like to utilise the time downloading aswell. As u all probably already know doing both at the same time frames up the game abit.

Any links to sites or information on this matter would be greatly appreciated, thx everyone.

uhh...powering 2 mobos at once isnt going to increase downloading anything, much less give you more fps. lawl.

i think what he ment is one to dl and the other to play games... sorta like 2 difrent comps with sharing one PSU

i guess if you really wanna do that you could always splice into the atx power conectors and buy a molex kit from frozen cpu or something... they sell mod stuff like that there ... and run the wires from there that way and have 2 atx 20 pin and 2 4 pin conections.... but you need a big psu to handle the demands and your almost better off to buy 2 mid range psus for probually less money and do ti that way.... you can get a cheapo psu off egg for less than 20 bucks and that would be good enough to run a basic DL station

Many people do this to their systems. Usually in server situations, but it will work for you as well.

• The Turbo-Cool 1KW PSU would probably be the best option to split and power two motherboards with all the "bells and whistles." You can check it out here. It's a little pricey though...avg. $490.00US. It recieved a 4.5 out of 5 in Computer Power User (CPU) magazine, if that matters to you. The cheapest place I found has it for sale for $470.00US here.

• If you don't want to make your own 24pin to two 24pin splitter, then buy the splitter here -or- here.

G'day metalkobra

The idea behind my thinking was to have 2 complete seperate systems in the one case. One for gaming the other for downloading/uploading, burning etc. By using only one power supply the weight and space would be minimised. also having 2 mobos it would extend the amount of hdd's that could be attached. The second mobo would be a micro with everything built on to minimise space also.

I meant to mention in my first reply thanking u fellas for such a quick response, so thx fellas.

Watertown1978 u hit the nail on the head mate. Thats exactly what i want to do. I was thinking of using 'Remote Desktop Connections' to switch between the two systems instead of buying a kvm switch box (saves space and money). Not to sure how much cpu resources RDC uses though, will have to check that one out as time goes by.

Xaine99 thanku for the links and information, they are exactly what i am looking for. When i finish the project ill send some pics in to see what u fellas think.

I have a 470W purepower psu, the 12v rail is rated 36 or 38 amps and caters for 9 hdd's + 4 or 6 fan connectors (from memory) i believe this psu would do the job adequately. Once again though time will tell the true story

Thx again fellas for your help

Thanks for asking about that--it's exactly what I need for Crunch--a 4 mobo Folder I'm working on...

This is the only other place I found that has it in stock.

http://www.pcgate.geomerx.com/index....&productID=775

If they're actually out of stock on that item you have two choices. Send an e-mail to the origonal makers of the unit HERE, or have a local company make it for you. If you can't find a local custom cable maker for businesses, then I know you can get one made at Computer Cable Connection Inc. in Bellevue Nebraska. As long as you have a credit card, they'll be able to custom make the part and ship it too you. They're really cheap.
