ya nice project we shouldnt be forced 2 buy compaq parts when u can proably get a regular supply for cheaper

this is a article that could have used a few 4 letter words in the description. i cant count the number of times that i have run into proprietary connectors. particularly the fan connectors on 2001 era dells. why michael dell? its just a fan.

Amen Daley, in fact there is no logical reason that cars can’t be modular. Aside from the obvious problems when a Chevy Aveo is treated to a 300+ HP Honda or Toyota motor, or a supercharged Ecotec.

“Though there are even simpler ways of bypassing the issue”

Thanks for nothing. Could we get a hint or a link? I am going to assume that you can trigger the PSU yourself, thus having no standby mode (I don’t get standby mode anyway, there is no need of it for 95% of consumers, and the other 5% usually just leave the PC on anyway.)

Using LM3940 would’ve made it much simpler as you don’t have to adjust the output voltage like he has done on LM317.

honestly, if i were on the compaq design team and trying to get a product out in time cheaply, i would really doubt that i’d be thinking about making the parts proprietary so that you couldn’t use it on other systems. the simple fact that they’re cheaper for me, and more importantly either reduce power consumption or make it easier to use a controller chip I want to use on the motherboard (presumably that’s why they want 3.3V out–either that, or they can get rid of a 5v-3.3v regulator on the board that they would otherwise have to use), would make it a no-brainer for me to use a nonstandard power supply.

I doubt using proprietary stuff had ANYTHING to do with making sure people buy your parts. The majority of people I’d be selling to if I were compaq would probably throw away their computers and get a new one if the power supply (or anything, for that matter) broke. The only people it’d target are maybe the 1% non-corporate, technically competent people who happen to buy one of these computers, and it’s not worth it to screw them over if unless there’s some greater advantage (cost).

Now that I read it again, I’d imagine having 3.3V standby has something to do with making solution size slightly smaller for the smaller desktop towers. It almost certainly wouldn’t be very significant (just one less 3.3V regulator onboard somewhere), but that plus the decreased cost makes it a no-brainer.

This is why i build my own computer, because of overpriced proprietary crap like this.

I also would highly advise building a PC from the bottom up or at least fleshing out a bare-bones box.
And for those that think it impossible for a layman to figure out;think again. It is an enriching experience to learn how your PC ticks ,what goes on inside the black/white box.
Plus there are undeniable perks of not having to pay some ass to install a simple wifi/nic/sound/video card or upgrade ram……install additional H.D.D ETC,ETC,Ect,ect….or the proverbial PSU.
modding a case is a bit on the fun side also and it can teach how to manage power supply connectors and familiarize folks with the headers on the mother boards such as usb firewire and other features not fleshed out to the front/rear areas of the case
