Antec 430w TruePower: Any way to Vmod this ??

[Hell-Fire]

Upon forther research, the TControl550 does indeed suck balls.

Looks like a marketing scheme to me! I would go with the standard Antec vmod for your psu. You should have a sense wire for all 3 rails running down the length of the ATX connector.

You can always PM or email me if you have any questions. If possible, send that damn TC550 back and get a refund...buy either the TPower550 (its hella cheaper than than the TC550), or the TTGI that was reviewed by OPP.

Both are easily modded, and I think that after taking the cover off the TTGI there are actually installed pots to tweak!

A third option is to check out PC Power and Cooling's web site.
I recently dumped my Antec TP 430 for a PCP&C Turbocool ATX 510. Rock solid supply with trimpots inside. I had them drill access holes in the case for the trimpots. I have not had to touch them. 1% regulation and a 5 year warranty.

I ask again...in total lostness.
What are the fixed resistor used in this mod?
those high AMP power resistors or regular 1/4w-1/2w resistor? TIA.

[Hell-Fire]

JINU117-----

You need to use a 68ohm fixed resistor...I dont think it matters which you use as in 1/4w or 1/2w, but I always use the 1/2w cause higher almost always is better.

Use the 68ohm fixed in series with a 10k VR.

sorry for the grave digging

now where is it supposed to go? 1 or 2?! (I connected to position 1, it seems to work for me) or it doesnt matter?

You connect the fixed resistor, then connect the VR in position 1 according to your picture.

The VR would be connected to the top leg of the fixed resistor, away from the ATX connector.

If the black rectangle in your picture is the fixed resistor, then yes, position 1 is the best place for the VR.

Sup ice ice.

lol...a moddin we will go a moddin we will go.....

Waiting on my grabbers to get here so I can redo the vdd. Also, found the data sheets for the ICs on my Ti4200..cant wait to vmod this thing and see if she breaks 16k or so.

[Ragnarok]

worked good

now i have 3.4V...

w00t, FSB already looks better

Antec quality is a bit overrated, if u ask me it looks like a pile of poo the internals...

[Hell-Fire]

Nicely done Rag.

Keep an eye on yer 5v rail as well when upping vcore.

[Fewture]

I did the mod.. Didn't see any difference at first, but when I was pushing the board the other day my Vddr got stuck on 3.23V. I looked at the Vio and saw it @ 3.28. I upped it to 3.45V and started benching again. After a few benchies checked voltages again and saw the Vddr @ 3.30V Whoopsie

Gues the mod works like a charm then only it doesn't help me right now. Something else is holding the board back.. Stuck on 237MHz right now.. 240 is bootable but highly unstable. My Corsair Twinx needs 3.2V @ 220MHz so maybe I should get some better ram first..

[Fewture]

pc ice,

Would you think modding the 12V rail would help getting 240 stable? Or would that only stabilize Vcore?

I cant find the problem m8.. Had Twinmos BH5 in the board yesterday..no luck. The ram was better but still the board crapped out at 240 (241 real).

Also..when I'm at say 7 x 245MHz the system boots perfectly but the screen is in 16 colors (or 256). Like it won't load the vga driver, Argghh This 240 thing is driving me crazy

I didn't mod the 12V yet because I think my PSU is max now.. Getting really hot.. It's and Antec TP clone 380W. 12V is dropping a little when on high Vcore. 5V is 4.95 as it always is.. 3.3V is 3.45. NB is flat and watercooled.

[Kunaak]

can any post actual pics of the mods?

Pics of the mods done are fine, I just need to see this myself.

also, heres what my antec true control does when maxed out.
the 3.3 volt line is actually lower then my vantec 400 watt, which comes at very strong rails at 3.5, 5.3, and 12.6.
but I've always used that PSU for power fans when benchmarking....

maybe time to give it another look

So on the 12v rail it´s a 68ohm + 10k vr. What about on the 3.3 and on the 5v rails.

[jonspd]

Bump

[Ragnarok]

3.3 use 10ohm + 1K VR

output u get is Vout = (VR resistance)/ (VR resistance + 10) * Vin

[tMQ]

any ideas how to mod psu that has no thin orange cable ? it is cheap 300w psu

I'd like to practise a lil' bit before I'll do mod to my true480

[HMB]

Is it possible to use a 10K or 1K VR and skip the fixed resistor for modding the 5V-rail? Its extremely low atm, 4.7V on molex and 4.3V reported in bios. If so what should I choose, 10K or 1K and how am i supposed to connect it? Just solder one connector to the 5V-sensorcable and the other connector to ground?

[lazytech]

uggggg two dam local radio shacks and neither og them have any of what i need. Imagine that.

[STEvil]

3.3v: 10 ohm fixed, 1K variable.
5v: ? (24 ohm fixed, 5K variable?)
12v: 68 ohm fixed, 10K variable.

A moddin' I shall go... 8-)

EDIT

Theres no 12v sense on my 400 watt Antec (generic) 8-(

[Jethro]

strange i just bought one of these and it rocks, no vmods required all the rails are perfect.

Awesome PSU! i love how quiet my puter is using all me fans on them fan only headers

[La1kr0diZ]

Does this mod apply to Sirtec High Power PSUs?

[STEvil]

It applies to any PSU with sense wires to the ATX header.

My Antec holds 5v/3.3v/12.5v pretty well perfectly all the time, but I want more... hehe.

[HMB]

Go figure, PSU was fried A capacitor was blown Gonna RMA it soon and report back if im going to Vmod it.

[Ragnarok]

I got a TC550 today, gonna do the mod on it as well, its 3.3V adjustment just dont go high enough ..

[xDUCK]

What will happen if I use a 68ohm fixed and a 1K VR on the 3.3v line? Will anything explode or is will it fluctuate like crazy, or what? What about the 5v line, is 68/1K ok with that?

Also, I wanted to know... The fixed resistor only has two contact points, and the VR has three, of course. From what I understand, I connect the fixed inline with the 3.3v sense line, and then I choose one of the lines contact points on the fixed resistor and attach the VR. Then I ground the VR. The setup should look like this, yes?
