I think it is simply a matter of you having version 1 and the link showing version 1.1 so the drawing doesn't match exactly. . I also suspect that 80286 marking is simply an error. (Not unheard of.) 80286 CPUs only have two rows of pins down each side. That socket has three rows which is consistent …

The MSI AM1I mobo has 2x 270uF on VRM-high and doesn't seem to suffer from random reboots: I had trouble finding good photos of that board but I did see one that showed an additional 270uF-16v and 4x 100uF-16v. Those are most likely all in parallel through the board on +12v rail so the total uF on …

In fact as the higher the capacitance and the bigger the cap can => the lower the ESR I've read a bunch of your posts and you clearly know your stuff but this statement simply isn't true. . There is no correlation between uF and ESR. Within a series of cap the ESR varies with the can size. The uF …

I also used silicone to glue together the caps on the ATX psu like the manufacturer had , just in case the cables start pushing them. That actually is not usually necessary. They only do that at the factory to hold everything in place so they can solder the whole board at once. On rare occasion …

I bought this Antec EarthWatts 380 w from a flea market,but it doesn't work,i opened it up,the seal was intact,it doesn't seem to be anything wrong with it no bulging caps,no burn marks or smell,nothing. It's weird i had cheaper powersupply with bulging and even liquid flown out of the caps and the …

All multiplication is done on the CPU. 33*4. Yeah, it's been something like 17 years since I played with one of those so my memory is a little off. That's what I get for refreshing my memory at Wikipedia. (Which amazingly has been edited since I read it yesterday.) I was trying to explain where the …

..... Am5x86-P75. Even during startup it says 66MHz, don't know if thats true, however as speedsys is showing P75-appropriate results. There are two 2x multipliers in play in that setup. The first is on the motherboard which is the 33MHz bus speed x2 giving you 66MHz to the CPU socket. The second …

Greetings PCBONEZ, glad to see you here around http://smileys.on-my-web.com/repository/Respect/respect-048.gif . I suggest everybody pay close attention to what this man has to say, he really knows the stuff. ... #2: There is a minimum total capacitance needed even in a motherboard VRM (both high …

Power supplies, unless specifically designed to use polys, are not the appropriate place for a poly upgrade. True but you have the 'why's' kind of wrong. Polymer caps are very fast, and would require all the circuitry behind them to be equally quick. This concern only applies to signaling …

300W Heroichi PSU: worth refurbishing? That depends entirely on the specific model you have. Many Heroichi (aka HEC, aka Compucase) PSUs were built with incomplete (only partial) input filters. (The input filter is a 2-way filter that, in addition to other things blocks, line noise both ways.) …
