Volt Modding the Tagan Easycon 2Force PSU Page: 1
Over the past year, Tagan have make a name for themselfs in the power supply world for making solid, reliable units backed with excellent warrenties. Personally i've owned two, both of which have been great, but have also suffered with slightly low rail voltages. Most of the time, this isn't a problem as the voltages are well within the recommended 5%, but if you are planning on some harcore overclocking, the higher you can get those rails when the psu is under load, the better.
In this guide i will show you how to volt mod your Tagan Easycon 2force series Power supply. This guide may well work for other power supplies that share the same internals as the Tagan, so let me know your experiences.
Opening up a power supply unit is DANGEROUS and will void your warrenty. OC3D will not be held resposible for any issues that may occur as a result of following this guide.
Now that we've got that out of the way, lets get down to business.
Its important to discharge any voltage held in the capacitors before opening up the PSU. This can be done by either unplugging the PSU from the mains, then attempting to turn your PC on, or following this guide on 'jumpstarting' your PSU.
Unscrew the 4 screws illustrated in the image below. One of them will be below a 'Warrenty void if removed' sticker.
Once you have lifted the cover off the unit you will need to disconnect the fan so that you can completely get the cover out of the way.
Now to find the potentiometers (pots)...

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.
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.
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.
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!
