FSP models are the ones I always buy. And there is just one pot for the +12v/+5v rails.
just received my fortron 530w, had to adjust the rails a bit.
i was skeptical about it being loud, tedinde and a couple were right, its just about dead silent from a foot away.
only problem i have is:
3.3v reading 3.47
5.0v reading 5.38
12.0v reading 12.66
even at these high voltages, my vcore and vdimm havent gone up, it actually stays the same or in most cases undervolts a little.
The motherboard determines VDIMM and VCore. You must mod your motherboard to allow it to use higher voltage.Quote:

heh yeah, i guess I kind of figured that out, thanks though. I've just have had bad luck with my DFI infinity and voltages. great board though, just need to get the voltages straight. I have another infinity that overvolted on the vdimm and vcore. But then again I always hear the phrase "no two motherboards are the same"
anyways, I'm loving this fortron, good stuff. I like this because my other psu actually only had one fan, but this has two fans, in push and pull method.
I realized, in order to increase the voltages for the 5v/12v, I had to rotate it clockwise to raise the voltages, however the 3v, I rotated counter-clockwise to raise the volts.
I got mine as well, running it like this for now:
3.3V=3.52
5V=5.46
12V=12.5x
Working good for me :)
Next up is a Vdimm mod.
Here's another feature of the Fortron:
Thinking my Fortron had failed, I setup my Infinity tonight with my TTGI.
Before this, my modded TTGI and my new Fortron seemed to be roughly identical, both have strong 12, 5 and 3.3 rails.
When I plugged in the TTGI tonight, the power connection to my floppy drive glowed red hot. I quickly pulled the power cord, everything is all right except for a burnt floppy power connector and the (already) failed floppy drive. The jury is still out on my Infinity and everything else plugged into it.
The Fortron was plugged into the same rig, unattended for over 12 hours while I was at work. Nothing was burnt on the Fortron because it has over-current protection. When the floppy drive failed and shorted the 12v connection to ground the Fortron simply shut itself off.
The TTGI did not :(
I still like my TTGI for it's good rails but I'm going to replace all my PSU's with these Fortrons. The Fortron's overcurrent protection saved me from a possible fire in my brand-new home today!

Red = 3.3v adjustment
Blue = +12v overcurrent adjustment
Fushia = +5v/+12v adjustment
Green = ???overcurrent adjustment or fan speed???
Just verified that the BLUE pot. is for +12v overcurrent protection. (it also may control the +5v overcurrent protection but I have not been able to prove that)
Is anybody sure what the GREEN pots. do? I always assumed they were related to more overcurrent protection circuits but others have said they control the power supplies fan speed. I took the DMM to the fans and I can't get those pots to change the fan voltage so... :confused:
i think the greens control the speed of the fan when the temperature gets too hot and spins up the fans. i believe when it kicks on these set how fast it will spin up to control the noise.
Found a problem with these PSU's.
They dont tolerate ground faults very well..
I had to stuff my 400w smartpower back in to run at the lan I am at right now.. :rolleyes:
Can you explain the situation? Just curious what happened and why shutting down during a ground fault would be bad?Quote:

TIA.
Same here - was the ground fault an open or a live ground?
Good question.. whats the difference? :D
Out where im living there is a grounding problem that doesnt seem to bug the PSU, but at the lan its worse and must be tripping some protection inside the PSU..
The rundown:
I shut off and packed up, drove to the lan.
Unpacked, set up, hit the power button and.... power for a fraction of a second.
Unhooked the ATX connector and jumpered it and it will turn on after cycling between on/off for about 4 seconds... and sitting for 5+ mins.
Odd..
I had similar problems at a lan with my 400watt..
This is the same lan where we tripped the buildings circuits when somebody decided to make microwave chips... so it didnt supprise me.
Open means that there is no ground.
Live means that the ground is carrying some voltage.
A simple line test tool is available at many hardware stores, it can find ground problems, polarity problems, etc.
No ground (open) is potentially dangerous because circuits designed for a good ground depend on it to keep chassis components at zero potential (volts).
A live ground can end up giving too much or too little voltage to a circuit, plus many electronic components don't like reverse bias (voltage where there should be none, as in a ground).
BTW, anyone know the value of the 12v/5v VR on the fortron? I had a lot of the blue goop lock on my 12/5v VR and even though I thought I chipped it off before turning the pot my ham hands pretty much destroyed the trim slot.
Now, the VR doesn't have enough pressure to keep the wiper reliably pressed against the pad and my brand-new PSU is useless unless I replace that VR.
Let me put it this way: I can stand on the cement floor and press my thumb to the computer case and revcieve a mild shock treatment... :D
Out in Del Bonita its very mild (you get it in the shower too, if you hold a hang-nail against the taps), but here... holy crap!!!
I have it working now, by the way... plugged into a different wall outlet.
I also figured out what was tripping it: I was getting a feedback voltage through my monitor cable because of the... messed up grounding...
On a related (?) note, the AN35N is having troubles with its USB... now whether this is related to my prodding around with the 2k ohm pot a coupel nights back or the grounding issues... we'll find out pretty quick..
Geeeeeze. That's messed up.
I wouldn't be one to screw around with ground potential. Have an electrician add a few more ground rods near your main service(make sure to get other services located first so you don't end up going through something else) and have him upgrade your main grounding.
I put a 200A main in a few years ago and put in a ground array since we have a good amount of clay and rock. Four 8ft rods worked nicely. ;) (after about 2hrs of pounding)
I'd say this proves the Fortron Source is a top notch power supply. It says a lot that it senses this sort of condition and shuts down.
Indeed :toast:
My monitor even has the wavy lines on it theres so much voltage in this floor... lol.
Heres a pic of my new 5v and 12v rails, too... although they read about .2v low (havent measured with a dmm yet.. messed with the pots last night while I was having PSU troubles.. :smileysex )
why are you guys running your rigs from the wall???????????????
35 dollar APC 350 UPS from compusa is exactly what you need.
Heh, I need one. I think i"m pretty close to blowing a fuze, when I turn on my fan with my speakers plugged in they pop.Quote:

Or when I plug in anything else for that matter.
I have an APC that works well.
That aside, I tore my rig down and am home now, but am experiencing the weird no-power-on thing again?!!?
WTF is up with this?!?
At the lan if I jumpered the PSU repeatedly (on/off/on/off/on/off.....) for about 10 seconds it would eventually run up to full power and turn on.... but that isnt working now...
*sigh*
Been doing and recommending that. Better than surge protecters.Quote:

I used to have a refridgerator at my first apartment. If you brushed against the stove and grabed the fridge handle, you'd sware you stuck a key in the wall outlet.
I would of fixed it, but when your 18 it's kinda cool for company!!
But that was long ago
lol
Maxvla,
What's the model number on the UPS you are recommending? I think I should probably get one here soon.
Thanks :)
Is it this one perhaps?

Office max has a few cheap after rebate. A belken 500va $49-$10 rebate this week. I bought 2. One online then went and picked one up.
Same price as your CUSA model but a higher rating. I Modded one with a motorcycle battery before and got a little over 1 hour run time!! I use them for power conditioning and surge protection for cheap.
Good til Saturday
