Power Supply Alignment Mod

[Nohto]

Power Supply Modifications
Many users are experiencing extremely low 5.00V values when using higher than default Vcore settings in bios. Components used for our alignment and modification are of the highest quality in the electronics industry and the components have tighter tolerances than those used by the factory. After the modification you will notice that the fluctuation in Vcore and 5.00V rails will hold a tighter variance in idle and full load conditions resulting in overall system stability. The only drawback is that the 12.00V rail will be around 12.60V which is within 5% of optimal. This may possibly lead to shortened component lifespan. This modification is only recommended for those who are using water, TEC, phase change and other extreme cooling methods. The modification is implemented with the factory designated overload protection taken in consideration. Each unit is tested for 48 hours before shipment back to the customer.

Has anyone had this mod done to their PS? And if so how did it work or have you heard of any other method to raise the 5v values.

Yes I've had it done to both my Enermax PSUs. It helped out greatlly with no ill efects what so ever. Made for a higher overclcok with an XP2000 chip I had tested the PSU with.

I found a thread that describes how to mod it yourself CLICK (http://www.amdmb.com/vb/showthread.php?s=&threadid=54084&highlight=enermax+r82) It looks pretty basic.

I run an enermax 465watt psu modded by XTW and my 5V stays at 5.13V under load and 12V runs 12.6V - 12.54V.

I wouldn't have any other psu for what I Try to do - but the mod is for if you run extremely high overclocks andsych that draws a lot of power - that way it will drop your rails down to spec in where an unmodded psu would be feeding power to a stock system.

But Gooch is clearly the guy for this thread!

I did the mod myself described in this thread back in the day when the thread was new.... and yes, its pretty easy to do and works great.

Here are some voltages on my PSU . They look nice , but the +5V drops at loads to 4.6 V . I think it is keeping me down to OC some more....

There is also a 5v modification that can be done to the mobo itself. Some of the Kt133A boards had some issues with 5v rail dropping under load on a psu that could handle what the mobo was asking. The solution for some was connecting a a +5v source (I chose a molex connector) to the "dump" pin on the mosfets for +5v. These are usually the mosfets closest to the cpu on abit boards. I did this to mine (old KT7), and it helped a ton with stability. I'm thinking about measuring all the voltages on the mosfets again now, and doing it for the sake of doing it on my KX7. Heres a pic (VERY blurry sorry) of it on my KT7.

You can see the molex and where i epoxied it to the motherboard. It all came off without much of a trace of it being there. Pretty easy to solder to that HUGE metal tab.
