![]() Through this, the PSU can provide -12 volt against GND. (Image)Īlso, I haven’t removed the blue wire. Basically, by shorting green and black wires together the PSU turns On and disconnecting them, the PSU turns off. Now, I should mention that I have short the green wire with GND to keep the PSU (PC power supply) ON forever. Also, I have replaced four 12V carrying yellow wires and 4 ground wires with 0.5sq mm blue and black wires respectively as shown in the image below. So, I have removed the enclosure and have taken out all the unnecessary wires. Most importantly, we need to get rid of this enclosure because we can’t fit LTC3780 modules inside it. These thin wires single-handedly, neither support 288W nor 130W of load, and there are also a bunch of extra wires are coming out from the PSU that eventually have no use. ![]() Good enough to proceed but with its output wires it is definitely not recommended. The power supply I’m using that according to its label, can output 24A on its 12V rail, Total 288W. Of course, we can use ‘PC Power Supply’ as a beginner’s bench power supply but we’re not here to do this rather we’re here to modify the PC power supply for the LTC3780 modules. How to Use PC Power Supply as a Bench Power Supply? ![]() (Optional) A ‘couple binding post’ and single ‘binding post’ – if you want to take out -12V rails. Also we need some complementary components like fuse holder, AC socket, Fan, fan grill, screws and 4 binding posts.
