Problems with 12V and 5V lines on a PC ATX supply

Lonely Auto-contradicting Psychotic Senile Ozzie Troll Alert! LOL
On Fri, 21 Feb 2020 09:26:51 +1100, cantankerous trolling geezer Rodent
Speed, the auto-contradicting senile sociopath, blabbered, again: FLUSH the two abnormal sociopathic trolls' latest troll**** -- TYPICAL retarded "conversation" between sociopath Rodent and sociopath Birdbrain from August 26th 2018: Birdbrain: "I have one head but 5 fingers." Senile Rodent: "Obvious lie. You hairy legged cross dressers are so inbred that you all have two heads." Birdbrain: "You're the one that likes hairy legs remember?" Senile Rodent: "The problem isnt the hairy legs, it's the gross inbreeding that produces two headed unemployables like you." Birdbrain: "So why did you mention hairy legs?" Senile Rodent: "Because that's what those who arent actually stupid enough to shave their legs have." Birdbrain: "You only have hairy legs if both of the following are true: 1) You're quite far back on the evolutionary scale. 2) You haven't learned what a razor is for." Senile Rodent: "Only a terminal ****wit or a woman shaves their legs." Birdbrain: "There is literally zero point in having hair all over your body." Senile Rodent: "There is even less point in wasting your time changing what you are born with." MID: |

Sorry for the crosspost, I'm not sure which of these groups are active. On el cheapo SMPS the primary supply is the 5V whose feedback controls the conversion transformer. The 12V supply is derived from the same transformer so if the 5V is not breaking into a sweat not enough current is available in the transformer secondary to get the 12volts up to regulation. Ok, I do have a degree in electronics, but it was a very long time ago. Can you go into more detail? You already know the answer, put a load on the 5 volt line and all will be well. Or buy a single power supply that can handle the full load. They DO exist, but they ain't cheap!! I just found a 1kW one from China for under £40. The people over in the electronics groups seem to think they're fine. And since my policy is to always run a PSU at 50% load for extra reliability, longevity, and voltage stability, it should work. If not I'll be getting my money back and a free supply that will work for something else. |
