Handmade Silent Power Supply


   For testing of the new PSU I didn’t take out of the case the old power supplies, I simply joined the green wire of the new PSU with the same ones of the old power supplies. I was able to complete the PSU cover for the better ventilation and to make highlighting, anyway. I plugged in motherboard, video card, and hard disk from the new PSU. CD-RW, DVD-ROM, highlighting, and everything else lived using the old power supplies. The start succeeded. The computer loaded on.


 
   I’ve been testing it in minimum load for about an hour. The passive radiator didn’t heat up at all, the power transformer (#1 in the picture) and the toroidal throttle (#2 in the picture) heated up a bit. The transformer’s temperature was 27 °C, and the choke’s – 29 °C. The DT-838 device was used for thermometry/

   After that I loaded the 3Dmark 03 program. Have been testing my PC for several hours, I checked the temperature of the PSU components once again. The throttle was the hottest (#2); it heated up to 60 °C. The transformer (#1) was the runner-up – 50 °C. The electrolytic condensers with throttle at the PSU outlet got the third place – 45 °C. The big radiator heated up to 29 °C. The room’s temperature was 22 °C.

   As a conclusion, I may say that as temperatures are not very high, one can turn out without fans. Probably the second throttle on the toroid didn’t heat up because of the small load of 12V power line. For dependable service of the modified PSU it is necessary to replace the PSU solid metal cover by the cover with more vents. I’ll probably make a big window in the cover and cover it with stainless steel netting. The greatest drawback of this construction is impossibility of standard setting in the PC case. But if you use the passive radiator of smaller size, then this drawback will be able to be eliminated.

   Good modding everyone, Clear66

Non-constructive thoughts about modding...

    All began when one day my neighbour, he is Automatic Control Engineer, came and started to beg me to give him one diode. When I asked him why, he typed modding in a search engine. And it had a great effect on me. I was sick about it. Maybe there is nothing accidental in the world and this modding seed fell into good soil. All my life I was interested in design.
