Hey fellas,
I'm in a bind with my PSU right now. Basically, the 12v and 3v lines I ran with my epox board aren't acceptable on the abit ic7 max3. I have adjusted them and adusted them...........and adjusted them for a couple hours in small increments but can't find the default setting for the pots. By now I've turned them several revolutions to the left and right.
Is there maybe a pin or something to reset them?
:cry:
You mean a 'default' setting?
I doubt the pots have anything like that. Is there a chance
they had some plastic on them to prevent movement when you
first started? If so maybe you can tell from the broken edges where they were originally.
If not you may have to adjust them under load with a MM and try to get them
back to specs.
well just found out the pots are marked with a green line so in theory I should be able to line these up with the overvoltage ones and be at default settings. we'll see.
this is what is being read by speedfan and sisoft, as I dont have a DMM to see what the actual rails are. so what do u think? so do u think these should be ok for my 24/7 use (gaming, overclock, web browsing, etc)?

thanks in advance
too all those experiencing weird readings on your rails -
I was gonna send back a refurb sparkle 530 for the same reason. You absolutely MUST be running a full compliment of stuff when you are measuring those lines. that means sufficiant lodas on all three rails. It will boot up with jsut about anything, but you will get some weird readings, like I was always getting 3.3/11.3/5.2 etc and could not get the 12v over 12 EVER.
key is to give it a good load, like with all your stuff, and the PSU side off. Boot into bios, take your readings, turn everything off and make minor adjustments to the rails between reboots.
Essentially I can run whatever I want now, best $55 shipped ever.
The picture on newegg shows a 4pin, yet the wiring diagram on the FSP Group website doesn't:

Still, the drawing is over 2 years old, so I guess it's really out of date :)
According to those numbers your rails are ALMOST out of spec ... too high.Quote:

Any idea how they fluctuate? In general, the more stable the rail the better
your OCing potential. Overvolting can be just as bad as undervolting.
I wouldn't adjust a psu using bios or any software readings- that's not accurate or safe.Quote:

Well, the Fortron has only 18A at 12v - I wanna run an 80W pelt on my vid card.Quote:

Now, if you have money to burn, how about this Zippy?
Those zippys have incredible rails no wonder people use em, 30A on 12V for under $100 = nice
I finally got the OCZ 520W powerstream after much debate over it and the fortron for almost half it's price. Selling point for me atleast was the easy access to the pots but i think i'll buy one anyway for the girlfriend's computer and see for myself which one works best for my situation.
As for the zippy that's a nice PS but WOW that's expensive :slobber:
perhaps I should have been more clear -
when I said boot into bios and take your readings, I did not meant to read them from bions, but rather through a molex atx connector like everyone recommends. Booting into bios jsut allows you to get true representations of voltages which you only get with proper loads on all the rails.
I have a fortron 350w that does not need to be hooked to anything at all to give accurate readings/tweakings of its rails, but this 530w requires a bunch of stuff to be drawing juice to be at all accurate. infact I think my unit was a refurb because if you test the rails with nothing hooked up, the 12v line is waaaaay out of spec. heck I almost sent it back myself.
getting real clean power from it now, in fact the 3.3v line modded to 3.7v is powering my new 2x512mb bh-5 to 270fsb with more head/voltage room and nary a crash or hiccup. Im sure the other psus are quite good butone would have to turn m,y arm quite painfully to get me to switch from fortron. they just rock. Ild love to see a modular PSU from them!
tronik, what exactly is your bios reading your 12v and 5v rail at?
I run mine at around 12.1-12.5 and 5.1-5.15. cant remember which. its the 3.3v I am overvolting the crap out of. ur cpu and vid card get the 12/5v, I dont want to anger them. mem seems to tolerate high volts alot better.
I just built a new Dual xeon rig. for the hell of it i used my fortron Aurora 300 watt in it. with a pair of 2.8ghz Xeons @ 3.65ghz each. running fine for the last 24 hours, I didnt even have to crack the case on the fortron and adjust the rails, they are dead on!!!!
According to my KillaWatt Meter. the duallie Xeon rig is pulling 235 watts. Again no one's computer uses 500 watts.
if your rails are too high, will u be able to tell by ur system acting weird every now and then, or is it more like one day of all sudden something could burn out?
several options.
Caps could burst
mosfets could burn up
diodes may die
IC's could burn, resistors may burn, etc etc etc etc etc...
Realistically it isnt that likey though ;)
On the overvoltage pots which way does which? Does turning it to the left raise or lower the limit. Also, is just the far left of the three large pots the OV, and the pair on the right the fans or are they all OV pots. I read through 11 pages here and most people feel the two on the right affect the fans but I have cold air running thru my rig so I can't test that theory. just curious and thanks in advance for any help/answers. Can't say enough how happy I am with this baby under the hood. Runs my infinity without a hiccup.
Maybe this thread can help ...Quote:

Thanks for the link. I've read that one and they only say don't touch them and just assume they are overvoltage. My rig doesn't shut down I'm just curious as I did move one mistakenly once and put it back in the same general area. Thanks anyways :toast:
Adjusting my PSU was a :banana::banana::banana::banana::banana:...have fun guys LoL! Two pots turn all 3 rails.
I had 3 for 5/3.3/12 in mine.
two overvoltage/current (?) pots.
so are u saying it was hard or what lol? to me it was very easy, as it was for everyone else Im sure... :rolleyes:Quote:

This multimeter cost me $3! :banana: :banana: :banana:
haha sweeet. :D
where did u get the multimeter from?
