Tagan 480Watt-U22 -> no voltmod needed!

no probs m8
i'd love one of those boards

It will be the last one for me till '07 (thats what I said a year ago )

hehehe, i know what you mean, upgrading and overclocking my pc has become somewhat addictive

Yer well, since becoming housebound a few years ago it gives me something to do and keeps the mind ticking over, though I was lucky enough to kill maybe 3/4 of my brain cells in my younger days

Nice mod! It looks like a well designed PS too. Any problems with voltage fluctuation over time? Reason for asking is the brand of caps (fuhjyyu) aren't of good quality. They tend to bulge over time and I've seen voltages fluctuate as much as .30 on the 12v rail. Whenever I mod a PS, I replace these caps with Panasonic FM's and no worries about the PS crapping out in 6 months to a year. Voltages on the rails are totally stable with fluctuations dropping to .01 or nil.

Thnx for the mod guys. Really useful!

I went out and bought a DMM today from Radio Shack ($25.47 w/Tax and Battery in NY).

I plugged the DMM into one of my molex's and it read 12.06v. I fired up ATi Tool and ran artifact scanner which stresses the CPU & teh Video Card. It dropped to 11.84v!

So, I took the comp apart, and opened the PSU. Found the pot and twisted it w/some needle-nosed pliars. The PSU was switched off @ teh back, but..I accidentally touched the solder on the plug in the PSU that goes to the wall socket. I got electrecuted w/120v lmao! I let out a yelp and cursed it off, I'm fine.. I'm just a daring..sometimes stupid 14yr old. So, remember to unplug your power cord haha.

Anyway, I turned it 1/4 a turn, fired it up. Read about 12.38v. (This was jumpered with 1 hdd plugged in.)

So, I plugged the rest of my equipment back in (mobo, vidcard, hdds, etc)

Fired it up, w/multimeter reading it. 12.35v idle, 12.16v load. Not bad!!!

(This is in Dual Rail mode)

Heres some pix.

guys do you measure your voltages with a multimeter or only look them up in MBM5 or other SW?

i think the SW is allways wrong. my 12V rail shows from 11.67-11.8V while with a multimeter it's perfectly stable at 12.2V (antec true 430W). what do you think about that? i trust an external reading device more than cheap motherboard sensors.

When I modded my PSU (read above) I jumped my PSU, plugged in an old HDD, and my DMM. (Multimeter.)

My software (Corecenter by MSI) is pretty accurate. The DMM reads usually 12.35v while corecenter reads 12.32v. It's the same way w/+5v rail too. DMM reads 5.25v usually, while Corecenter reads 5.18v.

I wouldn't trust ANY software. And, the +12v reading on DFI's board's are almost ALWAYS very low...so I'd get a DMM for systems running those especially. Cmon people, go to your local radioshack. They're $19.99, plus a $3 battery, and they're REALLY nice.

Spend $25, kill computer. Hmmm...

So... anybody tried on a Tagan TG580-U15 yet?

So... anybody tried on a Tagan TG580-U15 yet?

I got seriously sidetracked when I changed my board over to the Expert so had no time though my rails seem to be reported correctly now with a very minor drop under load that is well within spec

[no_n|ck]

Any pictures Pryo or alphaone?? I have 530-u15 and i need to buffed a 12v and 3.3v. Need pictures to see wich pot to turn up. Please guys.

[alpha0ne]

I have had a close look into the back of my 580 U-15 and in the centre of the PCB quite close to the mesh grill I can easily see two adjustable pots

I would guess they are for adjusting the rails

[no_n|ck]

hey alpha,

i was looking from the back but i couldn't see any pots...regarding the lines, 12v is at idle at 11.92v and on load drops to 11.78v...3.3v line is stady at idle but on load drops to 3.28v, this volts is reporting Everest & speedfan...now my question is; will i get better oc if raise the 12v line to 12.22, so when it will be at load it will drops to 12v? Can i reliay on MB sensor for readings? The 5v lines seams fine, itds 5.11 all the time (idle&load)...thanks in advance

[alpha0ne]

Your 12V line is still within spec. but if you can raise it then no harm in trying

The most important rails, especially for A64, are the 5V and 12V

I wanted to do the 3,3 vsence wire mod but when I did this to mijn 480W-U22 the 3,3V Rail is 4,77V
VR doesn't have any effect to this. How can i mod the 3,3V rail of the Tagan 480W-U22 ?

[DFI pit bull]

Tried this mod on my TG480U01, opened the psu and found the little white plastic X shaped screw, turned it clockwise a 1/4 like you guys said.

My +12 rail was 11.78 but now it's 12.08 and the 5v is also higher.
The +12 drops to a little under 12.00 under stress so I will raise it a little higher tomorrow.

Many thanks for this great mod

Hi there Dutch bastard It's my not mijn

I assume you did put a load on the 3.3V line?

If you did I might open up mine as it seems to be fine (Don't want to void warranty if it sucks already).
