Although I've had reasonable success O/C'ing my Athlon 1.2 (running at 1.48) /Epox 8K7A system, I like many other were bothered the low 5V readings from the Enermax (and other)P/S's. The voltage definitely got lower as you cranked up CPU voltages for O/C'ing purposes (around 4.86 and a bit lower for me). Unfortunately the Enermax doesn't have adjustable POTS (potentiometers or trimmers = a variable resistor on the P/S circuit board) like some other P/S's which allow (relative) easy voltage adjustment, e.g., you could actually make the 5v line run at 5v or slightly above and reach one's O/C goal w/ system stability.
I had read about adding a POT in series (in line)with one of the resistors (R82) in the ENERMAX EG465P (the 425v model) to make it voltage adjustable. I also read that you could electrocute yourself if those big capacitors discharge thru you, so I didn't exactly jump on the project. Also I'm pretty poor solderer. But since I had some time off, I decided to go for it. You have to locate and desolder one leg of the above resistor from the circuit board and solder two legs of the POT to bridge the gap. I used a small 1K Ohm cermet POT (<$3.00). This is the only part you need. I drilled a small hole in the back of the Enermax and glued the POT w/ the adjustment screw exposed, so easy voltage adjustment can done while my P/S is on. Of course you have to open up the P/S and remove about 6 screws so you can put the circuit board in position. I wore disposable latex gloves and had no mishaps (no scorch marks).
Well it went pretty smooth (see my "XP1600+ unlocking Nightmare" post in the CPU//Overclocking forum for a project that didn't
) and it's a fairly easy mod, even for a Klutz like me. I took some pics as I was doing the mod (including several of the mysterious, elusive R82 resistor), and if someone is interested, I can post them. I could never find any good visuals for this on the web. Hope this inspires (or amuses) ppl.
