Tagan 480Watt-U22 -> no voltmod needed!

[kakaroto]

Got the new Tagan 480Watt-U22 2force!
Very stable and cheap PSU.

SLI support split 12v 20A /20A or combined 30A
Better amps then the OCZ 600Watt!

On great change is this PSU contains three VR pots:

Here some pics:







As you see a very different PCB and inside then the Tagan 480Watt-U01.

The voltages where a bit low in windows. I used DFI ultra-D, 3000+, 6800Ultra PCI-E and 2x SATA 120GB.

Lines were (windows):

3.3v = 3.28V
5v = 4.95v
12v = 11.60v

When I turned the pots I get a superb boost!

New lines (windows):

3.3v = 3.28V
5v = 5.24v
12v = 12.30v

Those two pots shown on the first PIC, doesnt have any effect.
But the one on the right, there is a small pot.. this one works!

Great PSU Gives me plenty power for SLI mode for only 100E / 140$

yea there great psus. i have the old 480 without adjustment 28a on the 12v rail sits at around 12.09 idle drops to 12.03 load , and barely makes a noise with the silent fans. good price to

Hmm, so it's nearly the same as the older model. The tg480-U01 has a 12V/5V poti inside, too.

where do you check which model i have ???

Simple, on the box or product sticker.

U22 version have a splitt 12v which you can set to combine.

Does the older model allso has the pots inside (I own one) ?

Ja volgens Celemine1gig wel

[alexio]

Ok dank je, weet je of er nog een mogelijkheid is om de 3.3V-lijn aan te passen op het oude model ?, bij de nieuwe gaan alleen de 5V en 12V omhoog, toch?

Ja v-sense mod, de 5 en 12v kunnen alleen verhoogd worden.

[pancake]

so does the old version have the pots ?

[alexio]

It does.

[TEDY]

can you say in english please?

i got U01 model

need better +12V line.

[alexio]

What would you like to know?

[pancake]

i was uinder the impression it had no internal voltage adjustment

[pancake]

yep it does work on the 480 tgu01 , just did it theres a little pot on a board turned it a bit and volts went upto 12.35 , 5.16 , 3.29. dosent seem to bother the psu as the smart fans are still spinning slowly. got a pic of the pot but its crappy quality. but the pots easy enough to find , its kind of a creamy white ish color

I also have 480-U01 and I couldn't find any VRs when I disassembled this PSU...

I also took few pics of it... and there is no sign of any VRs... Could you please show me where is this VR located in U01 model.

Here are pictures i took:






More pictures here...

oooo lejga tribesman

[DeltZ]

what on earth!!!!...

why is my 480 u01 different from yours... I JUST had a play around...and i don't even need to disassemble...



I got a VR on this PCB :/
and i turned it just under a quarter way round...and bam.... 12.4 volts and 12.2 volts under full load...(was 11.8)

Vcore still isn't great though..i need to solder some more capicitors in parallel...that's where hipro's IC7 mods will come in

[pancake]

this is were it was on mine. bad picture quality as i never took the psu fully out of my case

[DeltZ]

yep...EXACTLY the same here...right out infront of your eyes when you open it...a little weak plasticcy screw thing...orange..

[TEDY]

so you just turn it with some small screwdriver a little and then ? close it back and test ?

[pancake]

i had mine powerd up and in the bios just turned and watched the volts go up and settled on a nice number

[DeltZ]

yup...just turn to your hearts content...just be careful...it's a not like a 24 turn VR it's like...1 quarter turn gets you about 0.4 volts

[TEDY]

I have 12.02 now in bios...think it's too low for my need...pancake do you think n00b as me can do it ?

[pancake]

yea sure just dont touch any caps or anything as they hold a big charge. just take the top off and the pot is on the circuit board near the edge , its very simple
