Typical mains power for mid-range PC?

Rod Speed wrote Phat Bytestard wrote kony wrote Tell that to anyone who has had a heat induced failure. Bet they'll be glad to know you pretended to know better. All failures are heat induced in electronics. Wrong. Most obviously with static damage. You actually think there is no heat in an ESD event? Pathetic, really. Then there's when a bond wire comes off... Even if that happens in the micro realm, and is not readily observable externally. Pathetic, really. You really have to give up this childish lame. It's totally meaningless... really. Pathetic, really. You probably think there is no heat in ultrasonic welding of plastic too. You'd be wrong on that one as well. Having fun thrashing that straw man are you, ****** ? No wonder you got the bums rush, right out the door. |

Bull****. Ripple has a very specific definition, and that ain't it. So sorry but ripple is ripple, including all causes... not just the ones that suit your blind argument. Ripple and noise are defined as periodic or random signals over a frequency band of 10 Hz to 20 MHz. Your transient current draw CRAP is NOT ripple. What did you expect to be this transient when it comes from multi-MHz if not GHz chips, at least dozens of KHz switching? This is not like some motor that is a one-shot turn on. These are constant variable loads that induce more rail ripple than put out by the PSU itself. You're an idiot. |

I've designed and characterized far more power supplies than a retarded **** like you ever will. I'm not interested in your ego or characterization, rather some real-world testing experience would be relevant. You have not done that relevant testing on a modern system if you have not observed this load-induced ripple. Characterization of a power supply IS bench/system level, you stupid ****. Did you think the term meant "I wrote some details down on paper"? If so, you are an absolute ditz. |

This is pointless, anyone can look on the bottom of their drive and a large percentage will see there is no tab. They aren't even sunk on the underside to the copper either, at least none that I've aware of and I ALWAYS examine drives. This proves that you know little or nothing about how transistor and FET packages are made. It also shows that you are a mere observer, not an engineer. "I ALWAYS examine my drives." Whoopie doo, little boy. You have proven that you know nothing about how dissipative devices are made, let alone how the die is thermally coupled to the packaging... ALL of the packaging. And yes, a hard drive's PCB assembly uses conduction cooling methodologies to manage thermals generated by driver devices. Both those for the spindle as well as those for the head actuator, and read/write head(s). You truly are clueless. |

Typically on modern parts you may have some SMT transistors with tabs but the rest are sunk by their leads only. You're an idiot. The leads have NEVER been a thermal path. They are too small to make a significant difference. ALL SMD transistors that are power devices have tabs, whether they are exposed after assembly or not. You have succeeded in making your most retarded remark yet. Talk about being not worthy of having a conversation with... you are that, boy. |

Try learning some social interaction skills. ****wit. *plonk* Congratulations for participating in the most retarded behavior in Usenet, chump. Announcing your filter file edit. Oh boy... you're a *real* man. As to interactions, go back in the thread where the ****tard started insulting me, and you'll see why he gets no quarter. Nor do you, you retarded twit. |
