Founder StamatisX Posted August 17, 2011 Founder Share Posted August 17, 2011 I was thinking to make an adapter that will combine 2 PSUs into a single output. They will work in parallel so they will balance the load. ----UPDATE---- Check this post: http://forum.techinferno.com/alienware-m17x/1044-%5Bm17x-r2%5D-dual-psu-2-x-240w.html#post22860 4 Quote Link to comment Share on other sites More sharing options...
svl7 Posted August 17, 2011 Share Posted August 17, 2011 (edited) Cool idea... I'm curious whether this can/will work...Female jacks which should be compatible click here or here. I don't know about the male parts, but maybe you can hack something together with these. Edited August 17, 2011 by svl7 2 Quote Link to comment Share on other sites More sharing options...
Founder StamatisX Posted August 17, 2011 Author Founder Share Posted August 17, 2011 awesome! I will probably need only 2 females and one male (so I updated the first post) Quote Link to comment Share on other sites More sharing options...
mw86 Posted August 17, 2011 Share Posted August 17, 2011 Awesome hope it works it would make it like the theory of the Clevo models with dual PSU. Looking forward to the results of your experiment. Quote Link to comment Share on other sites More sharing options...
katalin_2003 Posted August 21, 2011 Share Posted August 21, 2011 You'll need a diode bridge for them to share the load equally! But if you're "sadic" enough match four diodes and DIY lol 1 Quote Link to comment Share on other sites More sharing options...
mw86 Posted August 22, 2011 Share Posted August 22, 2011 Great advice Katalin! +rep Do you have experience in a similar mod? Quote Link to comment Share on other sites More sharing options...
Founder StamatisX Posted July 12, 2012 Author Founder Share Posted July 12, 2012 Still a work in progress since my job is leaving me zero free time now... What needs to be done is to find a way for proper load balancing (one PSU has 18.5V and the other has 19.7V output) so stay tuned.. 3 Quote Link to comment Share on other sites More sharing options...

svl7 Posted July 16, 2012 Share Posted July 16, 2012 Looking good! Going old school with the volt- and ampere meter? Quote Link to comment Share on other sites More sharing options...
Founder StamatisX Posted July 16, 2012 Author Founder Share Posted July 16, 2012 always, plus more responsive Quote Link to comment Share on other sites More sharing options...
svl7 Posted July 16, 2012 Share Posted July 16, 2012 Yes true, easier to notice spikes. What exactly are the other three parts? Quote Link to comment Share on other sites More sharing options...
Founder StamatisX Posted July 16, 2012 Author Founder Share Posted July 16, 2012 those are diode bridges, I will use one or two of them to lower the voltage output so both PSUs are equal. Probably I will need one or two, the other one is spare Quote Link to comment Share on other sites More sharing options...

AssimilatorX Posted July 22, 2012 Share Posted July 22, 2012 If you manage to get an old Dell XPS M1730 PSU, is exactly the same size as 2x the Alienware M17X-r2s PSU so theoretically you would be able to fit the two psu into the cover (I had XPS m1730) 2 Quote Link to comment Share on other sites More sharing options...

AssimilatorX Posted July 23, 2012 Share Posted July 23, 2012 Yepp it is a brick literally.... LOL 230w 12v enormous in size and weight almost 2.2kg I got one exactly the same just with 8800M GTX which failed after 6 months and dell could not replace them. I loved her.... 1 Quote Link to comment Share on other sites More sharing options...
unreal25 Posted July 29, 2012 Share Posted July 29, 2012 LOL. That brings a totally new meaning to the expression "power brick". And I thought M17x was big and heavy! Quote Link to comment Share on other sites More sharing options...
potatorage Posted July 29, 2012 Share Posted July 29, 2012 Have you found a good way to balance the loads? I've noticed that sometimes one power supply supplies considerably more current than the other. Quote Link to comment Share on other sites More sharing options...
Founder StamatisX Posted July 29, 2012 Author Founder Share Posted July 29, 2012 yeah true, the load is not perfectly balanced but it's not that bad either. I see something like 9A on the one and 6A on the other. I don't mind the difference but I guess you could measure the voltage output and use an extra diode to lower it in case there is a difference.

mw86 Posted September 19, 2012 Share Posted September 19, 2012 Epic front page guide on dual psu. You are awesome StamatisX. I love the pics and video. Keep up the modding bro! I love the analpg meters too great touch. 2 Quote Link to comment Share on other sites More sharing options...
HOPELESSLYFAITHFUL Posted September 21, 2012 Share Posted September 21, 2012 i like to think i am very well read on power and stuff but i would have never guessed this would have worked lol....for several reason but i guess i would be wrong...and thats a good thing ^-^ Quote Link to comment Share on other sites More sharing options...
imsolidstate Posted October 24, 2012 Share Posted October 24, 2012 the load is not perfectly balanced but it's not that bad either. I see something like 9A on the one and 6A on the other. StamatisX, what is the maximum current you've managed to pull with your setup? Is it 15A? And what was the voltage at the maximum current? Just wondering what your total power consumption was.Also, you shouldn't need a diode bridge since you aren't rectifying any negative voltage. You only need one diode per power supply input, to make sure that a power supply never sinks any current. Quote Link to comment Share on other sites More sharing options...
