same here

Jus got a 510w Deluxe and tested the rails with no load attached to anything bar the 12v rail.

With the internal pots maxed (no mods) I got:
3.3v =~ 3.63v
5v =~ 5.23v
12v =~ 12.24v

This seems a bit high on the 3.3v rail for a non-modded PSU, not that I'm complaining

are you guys doing the readings with load across all rails or not?
how much will my 3.3v rail drop under load?

The reason I ask is I hav a NF7 modded to 3.2vdimm, is it likely the 3.3v rail on this PSU will be enough in its present state?

That seems a little high...but not totally unexpected. With zero load..max 3.3v rail is 3.45v.

Mine needed to be modded to hit the voltages you are getting. Yes, I measure under load when I want to know the true 3.3v rail.

Maybe they only had the higher rated resistor on hand that day, and just installed that.

[BuickBeast]

man that 3.3v is high. It should power that NF7 vdimm fine!

[B]Sorry it took me so long to get back to this thread.

Now, simply cut the sense wire and remove a good inch or so of it. Solder a 40-70 ohm fixed resistor to the leads. Then solder a wire from the top leg of the fixed resistor (top being the leg of the fixed resistor that is attached to the lead that runs into the psu) to the middle leg of a 10k VR. Then ground out the top leg of the VR. Turning clockwise will increase the voltage on the 5v rail.

sorry to sound like a complete noob, but how do i locate the sense wire?

sum1 plzzzzzzz help me.............

these beauties don't come in 220V/50Hz do they?

I mailed them to ask but I didn't get a response...

If you are referring to the 5v sense wire, it is located near the middle of the ATX connector bundle.

If you are looking at the connector, you will see one end has an orange wire on each side. 4 slots down from that you will see a slot that has a thick and thin red wire running into it. The thin wire is the sense wire and the one to mod.

I included a pic of the PCP&C ATX layout for you to look over. Slot #4 is the 5v target, and slot #11 is the 3.3v target (but only if you are not planning on removing the internal pot and modding that way).

Hell-Fire -- Replace the stock 2k VRs with what ? I am curious about the mod that you used, and the results it generates.

B4 I go and buy stuff, want to make sure what wattage? (Whilst I be asking, what do you use hehe?)
Need to fiddle w/ 3.3V for DFI UT. Can adjust fortron 530 fine (3.46V gets me 3.3 vdimm ) but wont fit in danm PC-V1000 whereas trusty 510 does.

Await your answer so I get get stuff!!
Thanks MikeE

Guys , what about , last revisions? Are they with sence wires? or they fix that?

[REDKEN]

Hi guys!
This thread is just what I was looking for.
I already modded the 3.3 rail (which came out great and can reach 3.78v idle with no problems.
I have three questions I'm despretly searching the answer for and think will probably find it here.
Where is the OVP trimer?
If I adjust it and it doesn't give me the head room I want; Would replacing with a 1 or 2k trimmer be OK? and last but not least. How many volts would be OK to give to the 3.3 rail?
I seem to need at least 3.9-3.95 on my 3.3 rail according to my calculations to get up to a stable 3.6 vdimm under load.

[REDKEN]

Ok did some more searching and found this thread (seems stergiopilus had the same question as I )
But that leaves 1 more question for me... How high is OK to raise the rail for 24/7 use?

[Hell-Fire]

As long as the air coming out of the back of the psu isnt to warm...which is a relative term I know, then you can run pretty close to OVP regulation as possible without much issue.

I would try to run the 5v and 12v rails as close to +10% as possible, and keep the 3.3v rail about +0.3v higher than whatever Vdimm you plan to run as a max.

i am working on a solution that would simply raise the 3.3v automatically to match the Vdimm so that adjusting isnt needed on the psu side.

Thanks for your reply.

I'm sorry i didn't quite understand this
I plan on changing the OVP to a higher value (or lesser...I still don't know if I have to lower or raise resistance on the OVP trimmer) to get the PSU to 3.90
Most probably I didn't ask the right question I should have asked: Where should I set OVP to kick in before any damage occurs to the PSU?
I need to know at what voltage, does the 3.3 rail on this PSU get damaged so I can set OVP below that point.

Thank you for taking the time to help me out

[REDKEN]

OK I figured it out!

Please if you have the time look at this thread

Thank you!

OK, I swapped out the 3.3v vr, to get 3.73v max stable, for 3.4vdimm usable. All I could get my hands on was a much higher rated vr, so once I get past the OVP, I can probly go WAY higher. Ya just gotta be CAREFUL turning it, since it adjusts more with less turning. @REDKEN, did you swap out the OVP vr, and did it help ya get higher? Thanx.

[computerpro3]

on mine with an external 3.3v pot, I can crank it up to around 3.9v with no mods, for 3.7-3.85 usable vdimm as measuerd by multimeter on p4c800-e deluxe. HAven't tried higher. What is the OVP supposed to be set too; I wonder if they removed it when I told them I wanted to be able to use a really high 3.3v line while they were modding my psu....

I actually thought of that, just eliminating the OVP altogether, but I don't know enough about electronics, to know if it's dangerous or not. What if we removed the vr, would it still work? Maybe it'd need a short wire to fill the gap? I'd probly try something, if knowledgable peeps gave me some insight. computerpro3, have you looked inside your PSU, to see if the OVP vrs are there? It should be easy to look at the pics Hell-Fire posted, for comparison. Thanx much.

[spaceman]

Welp, I decided to change out the vr I had in, it was just TOO sensitive, and hard to adjust right. I soldered 3 wires to the PCB, and ran them outside of the case, to a 10k trimmer, the blue rectangular ones we're used to seeing. Then I pulled the fan, and installed my trusty Mechatronix 80mm, that I've been using off & on since the AX-7. Way better airflow. Only prob I had was, I first wired it to the stock plug, which wasn't feeding it enough juice, so I ended up rewiring it through one of the fan's screw holes to a molex, long enough to come around and back in the case. The air never gets a chance to get warm now, so I'm sure it's keepin my PSU nice & cool.

No I didn't swap the OVP VR. I just set it as high as it would let me but the PSU still shuts down at 3.80 idle 3.71 load.
I don't know what would happen if the OVP VR was taken out all together.

[spaceman]

Heh, I'm not exactly gonna scrap my 510 Deluxe, but I just figured out that my old Turbo Cool 425 gives me almost 4.0v on the 3.3v line! Simple reason being, the 425 has 40 Amps on that rail, while the 510 has 30 Amps. The 5v rail is plenty strong too, but I need to do the sense mod on the 12v rail. It's "only" pushin' 11.89v. It's kinda scary to think about, but if I find out 3.6v usable isn't enough, lol, I can always sense mod that line too.

Aside from the fact that I didn't need 510w, that's one of the reasons I got
the 425w instead. The stronger 3.3v rail.
Not exactly sure how relevent this is, the hold time spec is better too. (30ms vs. 20ms for the 510w)
My only complaint is the lack of an off switch on the back.

This is a great thread ... good info. Might there be one like it for the PCP&C 425?

[Fabietto_18]

hi, anyone have try to change the 5v pot? is ok 2kohm same for 12 and 3.3V?i've look there is resistance in the pcb join at one pin of the pot
thanks

i'm found the mod pot for 5v rail..look at http://www.xtremesystems.org/forums/...ad.php?t=46547

Has anyone found out how to get higher on the 3.3vRail without OVP kicking in?

Hellfire?

Mine can do 3.63v unloaded on the 3.3vRail as standard (+/-10% I guess).
But I want to run it at 3.8v-3.9v for daily use... can anyone help me with this?

I am going to change the internal 3.3vRail pot. But I don't know where the OVP pot is... to start with I'll just try turning it to the max it can do, then if it's not enough I'll replace it.

Could someone please:
1) Suggest a good 3.3vRail pot for 3.9v max
2) Tell me where the OVP pot is

Thanks in advance
