Thanx for the clarification, I know nowt' about electric...

My next question was going to be which components actualy get hot. the resistors and mosfets for sure, but transformer?( that's what BR put the block on as well is'nt it?) coils?, ect. do they get HOT or do they get hot ?...

A quick question on my Enermax 350watt PSU, my 5&12v rails are slowly detiorating, I do have a problem with the ATX connector being a poor~connection, but even if I 'jiggle' it it does'nt improve (it used to), I'm down to 4.76 & 11.98 idle, used to be 4.90 & 12.13~18 when new. the mobo is relativley new but readings were same/simular on my old mobo (as was dodgy ATX connection, but not as bad).

What would cause them 'both' to deteriorate?, I could understand one or the other from a poor ATX connection , but both?. I understand the 12&5v rails are somehow tied together. would the common earth having a poor conection cause this?, or is it the PSU giving up the ghost?, OR is it just a bad ATX block?(gold plated Ennermax jobbie).

I'm thinking of soldering a block connector (3AMP Mains rated) to the ATX pins on the back of the mobo and bypassing the ATX connector. if I bundle the +12v, +5v & +3.5v's together respectivly I can use one ten~joint sized connector instead of a twenty. what do you think?. I've been told the 5v mosfet mobo mod is'nt such a good idea as it bypasses some ferous~ring, volt cleaning?, I've been told at another place that it bypasses the mosfet alltogether!!(by soldering +5v ATX/MOLEX wire to middle pin/cut off stump of mosfets)...

Gee!, was'nt such a quick question after all!!
