Crap - the PS went on the main computer.
I'm telling you, the next computer is going to be a Mac. F'in PCs. |

Really. Macs are sorta like boats when it comes to buying parts. Whereas
pcs parts are dirt cheap. wrote in message ... On Tue, 12 Feb 2008 21:49:28 GMT, Short Wave Sportfishing wrote: Crap - the PS went on the main computer.

The machine boots fine, but only lasts for five minutes then goes stone cold dead. I took the PS apart - everything potted which I suppose I should have suspected so you can't really tell if anything is cooked by looking. I hooked it up to AC and tested the loads - crapped out in less than five minutes. Held the loads fine up to failure though. Interesting. So the chore for tomorrow is get a new power supply. I talked to my brother tonight about it - he's got 800 or so PCs under his umbrella at the health centers he supports. He said that over the past three years or so, he's noticing more and more power supply's just crapping out. He stocks them now that money is tighter - can't just pull out the goodies and buy a new computer like he used to. He also used to spec out 500 watt supplies - now he specs out 750 to slow the rate of attrition down. Based on what I see with this bad one, he's right. |

If the fans are running on the 120v line voltage, then the computer's power supply is not affected by the load. But in the case of USB powered devices, the load is on the computer's power supply.

The SATA box has lots of pretty lights, too, and apparently they can be made to perform some sort of light show. Gotta love the few remaining geeks at HP. |

USB is pulling power from the 5 volt rail and that is the biggest supply in the system. Case fans are usually 12v but they don't really pull that much power. Back in the olden days the 5" disk drives were the power hog. Now it is the CPU, memory and processor on the video card. True enough, but watts are watts, regardless of which output of the power supply they come from. I just get a kick out of "cooling" the computer, using the computer's power to run the fans. Sorta like running a window air conditioner in the middle of your room, exhausting the warm air as it expels cool air. Eisboch |

Sorta like running a window air conditioner in the middle of your room, exhausting the warm air as it expels cool air. The only way that would be a valid analogy is if the case was sealed and did not exhaust the hot air. In reality a fan moves a lot more heat than it generates. They use low vontage fans to make listing a lot easier. U/L (and other NRTLs) scrutinizes line voltage a lot closer than it does low voltage from current limited supplies. You would also have the problem of PCs being sold around the globe with all the different voltages available. A PC supply has a fairly "wide mouth" running on virtually anything from 100 volts to 250 volts, 50 or 60hz. That's true. I studied it for a while because this laptop (HP Pavillion) has always run "hot" although it has three fans in it. I am sure the insides are good and dusty after 3+ years of almost constantly being "on". Maybe I'll try one. Eisboch |
The power supply done blowed up...

You're supposed to place your laptop on it and the fans in the platform are supposed to help cool the computer. But, it's USB powered, so whatever energy is used by the two fans is provided by the computer. Doesn't make sense. USB is pulling power from the 5 volt rail and that is the biggest supply in the system. Case fans are usually 12v but they don't really pull that much power. Back in the olden days the 5" disk drives were the power hog. Now it is the CPU, memory and processor on the video card. True enough, but watts are watts, regardless of which output of the power supply they come from. Don't forget that P=ExI, where P=power E=voltage I=current Since bus powered USB devices are typically limited to about 400mA (0.4A), that's only 2 watts. Insignificant compared to the typical capabilities of a PC power supply. A USB printer uses no power from the USB port. A USB card reader is typically bus powered. Well! Just goes to show how little I know about computers. I'll stick to audio amps. Eisboch |
