Who here modded the 400w Powmax PSU?

[VOLTAGE]

Hi, im new here. I was browsing the forums last night and happened to run into a post about someone upping the 5v rail on a 400w Powmax PSU by turning a POT (I dont have time to go through every post to find it right now). I have a 400w Powmax and it says made by "Leadman". Is this the same PSU? My 5v is @ 5.03 idle the drops to 4.98 full load using VIA's hardware monitor. Im running a 1.4 TBird @ 1.6 1.85v. Would upping the 5v on the PSU give more stability?

The only difference between when I OC'd from 1.5 to 1.6 is now sometime when under full load, the system will just restart! Temps dont go over 46c (full load) and im idling 41c right now. So mabye I need a higher 5v line? Like I said, its 5.03 idle, then drops to 4.98v under full cpu load. Do I need a steady 5v under full load?

Anyway, I took apart the PSU and dont see any POT's anywhere to adjust. I assume they are like the same thing that are on electronic RC Car speed controllers? (They're round on the circuit board and you turn them with a small straight screwdriver)

Can anyone shed some light on the situation?

Thanks!

BTW, my old generic 300w wouldnt let me OC over 1.5GHz. My new one allows me to hit 1.6GHz. Amazing how much just a PSU can make. ;)

Hi Voltage did you read my post on the importance of a PSU in the AMD CPU section of the forum. Anyway I have a Sparkle 400Watter and it has two pots that I can adjust. I haven't tried it because my 5 volt rail is 5.2 idle and 5.05 at load. However I reckon by increasing the 5 volt rail by adjusting a dial on your pod will not increase your clockability very much has your 5 volt rail is pretty high. What is your voltage from your bios????

It would be a total waste of time, your 5v is Exactly where it should be :)
Tinkering and adjusting the 5v higher than that could only be a bad thing... so in this case, it ain't broken, so no need to fix it :)

Cool. So then my problem with the system restarting @ 1.6 isnt the PSU then? Seems to me like when my AC is on, it runs more stable longer. As soon as I turn my AC off and the room temp starts to go up, it glitches out easier/faster.

Here is what it says from the BIOS;

Vcore = 1.91 (I actualy have it set to 1.85)
3.3v = 3.60 (Thats exactly what I have it set to)
5v = 5.02
12v = 12.06

That sound cool? Anyway, should I just be happy with 1.5 100% stable or tweak around with it a little more to get 1.6 100% stable? Would the voltage mod on the KT7a stablize it @ 1.6? Bios doesnt let me go higher then 1.85 on the vcore. Any ideas anyone? Better cooling, or more voltage or both?
