Intel did away with the AT standard and it's two separate "P8" and "P9" connectors by making the main connection from the power supply to the motherboard a single piece. Enter ATX.
Capacitor. The very word conjures up profound indifference amongst my family members every time I use it in conversation, which is surprisingly often. But, as many of you are aware, they are of profound importance to the operation of a Switch-Mode Power Supply, or SMPS for short. Today we will be taking a close look at how different quality capacitors can affect a computer power supply's output.
The rate hasn't quite bit doubled in subsequent years after Mr. Moore's statement was made back in 1965, but Mr. Moore was fairly close considering that, up until recently, data density has actually been doubling at a rate of once every 18 to 24 months.
Scary as it may sound, the people in my rants are very real. It's hard to believe, but the situations in my rants are real. And just as in real life, I never called anyone a name or expressed that I ever "hated" someone for simply being ignorant or stubborn. There's enough hate in this world, I don't want to add to it. As long as I am under the impression that people understand my rants as an expression of hatred towards people, then I'm going to cease going in that direction.
In my job I often end up going to AMD, Intel and Microsoft seminars and press conferences. When I meet some of the other techs at these get-togethers, I'm often reminded of the Simpson's character simply named, "Comic Book Guy".
I have a motto. I didn't copy it out of a book or translate it from ancient scrolls. It's a motto based on years of beating my head up against large, hard walls: "I have not seen everything and anything is possible."
"Don't you realize that any jerk off the street can buy that book, memorize it and still not know nearly as much as they should know to even get by and get an MCSE and then call you or me ever hour on the hour when they run into a problem because it wasn't covered on the test or their little 1,000 page paperback?" He seemed actually quite serious about his opinion about my little book.
Sometimes I've got to wonder why some people buy things just because of a certain brand name. "Yo, man. You know those Nikes aren't made any better but they cost three times as much, right?" Yeah, but they "trust" the name. I'll call them shoe-newbies because I've only had Vans for the last five years; each pair last me over a year and none of them cost me even $50.
I don't name names and I don't harass anyone to their face for not knowing something that I take for granted as common knowledge. What I do try to do is point out the people that lay the claim down that they are some kind of mega-expert, when they do not even have the knowledge that should be common for their position.
Now normally when lightning strikes, you see a flash and you hear the thunder go "KABOOM". Well, I don't think I ever heard the kaboom. Maybe I did and the stress made me immediately forget it. I certainly saw the flash though! The whole shed lit up like I had turned on 500 halogens in a 10 foot by 10 foot photographer's dark room. I saw little tiny arcs and sparks all over the tin roof that looked like the special effects from that 80s movie Weird Science. I threw the GRiD pad across the room and hit the floor.
As I look at these customers, I think of the people I deal with every day that insist on only Intel product. Never would they consider another processor or, in some instances, motherboard at even half the price. They'd much rather buy a 933 MHz CPU at $700 then a 1 GHz for $500, just because the $500 CPU is not an Intel.
Here is a collection of five rants from the tech bench of jonnyGURU. This is the original writing that earned jonny a spot on the Systemlogic editorial staff.
This is a list of manufacturers (or "brands" if they have their own UL) their UL Certification number (if applicable) and a list of brands manufactured by each manufacturer.
I don't expect the list to be "complete," so if you know of any manufacturers, brands or UL numbers I may have missed, please drop me an email at jonny at jonnyguru.com.
Please be able to substantiate any submissions. I appreciate any help, but if you tell me that you have a PSU called "Kung Fu" and you don't know who makes it, don't have a UL for it, etc. I'm afraid I can't use it.
To find a UL listing, look for the "Underwriters Recognized" logo (a backards "R" attached to a "U") and find the "E" plus six digit number underneath it. You can than look this number up on UL's website.
