Volt Modding the Tagan Easycon 2Force PSU

Inside The PSU

Inside the PSU

'Tidy but crammed' would be the best way to describe the internals of this PSU. Luckily everything we need is easy to get to.
Looking around, you might think you've hit the jackpot when you see the pots in the picture below, unfortunatly these are not the ones.

Tagan Pots Tagan Internals

Some sites say that these pots control the +3v & +5v rails, but i certainly did not see any change to the voltages at all when adjusting them. They might be responsible for for controlling the fan speed activation temperature but i have no evidence to support this.

Tagan Pots Tagan Pots

Here's what we are looking for, a small white pot, most probably covered in green glue to prevent it from being tampered with.
Use a knife to carefully scrape the glue off. Its important to make sure that there is no glue left around the edges of the pot, or this will prevent you from turning it fully round.

Turn the pot clockwise with either a screwdriver or pliers. The pot will only turn around 45° but its just enough to raise the voltage of the rails around 0.50v which was enough to bring my load voltages to 12.2v.

Voltages

It is possible to adjust the pot while the PSU is switched on. This will enable you to fine tune your load voltage, but also is EXTREMELY dangerous and you will need to take extra precautions to ensure you do not get an electric shock. Be warned.

Finally, put your PSU back together remembering to reconnect the fan!

This guide will show you how to increase the +12v and +5v rails on the Tagan Easycon and 2force series PSU's.

I decided to write this guide after finding that my Tagan Easycon was dipping the voltage on the +12v rail to 11.80v when running SLI rig.

I'd heard that the internals of the Tagan were in many ways similar to the internals of the OCZ 600w PSU's (which have adjustable rails), and found many guides about adjusting internal pots on the older series Tagans to gain increased voltages. However, it turns out that the Easycon series is quite different....

Step1: Turn your PSU off, unplug it and discharge any power left in the PSU by attempting to turn your PC on.

Step2: Remove the PSU from your case but try to leave it connected to your components as this will come in handy when setting the voltage later on.

Step3: Open the top of the PSU and disconnect the fan from the fan header, so that you can access everthing easier.

Step4: Looking around the inside of the PSU you may think that you've hit the jackpot when you see the pots below. THESE ARE NOT THE CORRECT ONES. As far as i could see, they have NO IMPACT on the voltages at all. In addition to this, it was a royal bitch to get the glue off them!



Step5: Look around the other side of the PSU, and buried under some wires you will see this pot, which no doubt will be covered with a load of blue glue.



Step6: Remove ALL of the glue using a sharp knife. It is important that you remove ther glue from around the edges of the pot as well, as this will prevent it from being turned.



Step7: Turn the PSU on, and switch your computer on. Enter into the computer BIOS and go into the menu that display's the PC's voltages. WARNING: When the PSU is turned on, all circuits are LIVE to be sure not to touch ANYTHING inside the PSU, especially the CAPACITORS. If you die - ITS NOT MY FAULT!

Step8: Using a screwdriver or pliers WITH PLASTIC HANDLE, turn the pot clockwise until the voltage is raised to the desired amount (The pot will only turn around 45 degrees, giving around an extra 0.5v).Then turn off the PSU (it will get very hot if left on too long without a fan).



Step9: Disconnect mains power, discharge power from PSU (as in Step1), plug fan back into fan header, and put case back on.

I managed to get my PSU to run at 12.2v under load with SLI which is a great improvment from the 11.8v it was providing before

That's right up my alley I luff volt modding, i volt mod everything I can hehe

The vdimm and vcore volt mods were fun as hell on my EPoX mobo... Got some rapage speed out of that bitch. Fraggles misses the 2.8ghz 3000+ Winnie Quote

I'd just like to re-itirate that if you're a noob and try fine tuning with the PSU on, these things pack enough voltage to KILL YOU. So please take precautions NOT TO KILL YOURSELF. Quote

Hahah tru dat ^^.

I did this mod on my 2Force, ty for the guide XMS. I did it a longgg time ago, when I first got it.

Did I get electrecuted? Yes..

one or two more words of warning

by doing this u can void ur houses fire insurance :P

and u decrease the current of the rails of ur psuQuote

LOL. Not by the PSU but by the wall outlet. 124v (measured w/DMM hahaha).

I guess I can be considered a mad scientist now

Heres my results from performing this guide. I don't know if my PSU is a newer model, different revision, or whatever but I have much more adjustment room. XMS said he could only go up to about 12.2v, but I'm 12.30-12.36v IDLE, with more room to go!

Anyway, results.

12v Idle:

12v Load

5v Idle

http://upload.overclock3d.net/downlo...?id=145&view=1

5v Load

http://upload.overclock3d.net/downlo...?id=147&view=1

3.3v (Doesn't change between load and no load.)

http://upload.overclock3d.net/downlo...?id=148&view=1

Nice voltages IMO. I have the 2Force, vs the Easycon, that may be why.

you can probly pick up a nice on for about $20 i would think?

radioshack,walmart etc should sell themQuote

use 2 if you want to be sure of the reading.

many of those i have used hasnt shown a correct value and i tried everything from real cheapos to veryvery expensive onces, more expensive than a 3200+ venice.Quote

LOL. This ones pretty accurate it seems. I tested it in my wall outlet and it was right on .

doesnt say anything how good it is.

measured up everything between 215-250v in the outlet here and its supposed to be 230v ac so it differs ALOT.Quote
