OCZ GameXStream 600W Power Supply

Anyone know if this supply (which appears to be a rebadged Fortron)
has internal adjustable potentiometers? I'm getting almost 12.5V on
the +12V rail and I'd like to get it closer to spec if possible.

Thanks.
 
Thanks. I came across this photo:

Cant get that to load for some reason.
I think I see one potentiometer (near the bottom of the large heatsink)
and I'm hoping another is hiding somewhere on the right side.

I cant see why anyone would bother to use pots to set the output rail voltages.

Bet that pot sets something else.
That's just barely in spec.

How did you actually measure it ? The motherboard
sensors are pretty crude 8 bit A/Ds that can be well off.
I'm trying for better.

Why ?
See above.

Didnt help.

This extensive review (and they love that PSU - it's rated "kickass")
doesn't mention that feature.

They *do* mention it in reference to some of the company's other stuff:

"Even though OCZ is a late comer to the Power Supply market, they have
had much success. I've reviewed both the PowerStream and ModStream Power
Supply products and they were excellent. The PowerStream was different
than anything else on the market at the time because it had adjustable
rails. For that reason, this product went over well with performance
enthusiasts. The ModStream's key feature is the modular cable design,
which gives the user cable freedom."

But it doesn't look like you have the feature.

Most users shouldn't be screwing around with that anyway. I researched the
OCZ PSU's when I was shopping around for one and I saw a number of posts
at the OCZ forum from people that had issues with theirs. For that reason
I settled on the Seasonic S12-600 but I suppose OCZ may have fixed the
issues by now.
 
Not obvious what the pot is controlling tho and its rather unlikely
to be controlling one of the rail voltages since it seems unlikely
that you wouldnt have more than one if it was for that.

I believe it controls just the +12v rail. I can do the same on my
Seasonic but the pots are internal, where they belong. :)

OCZ recently changed OEM vendors. Their PowerStream
supplies are rebadged Tagans, while their new GameXStream
supplies are rebadged Fortrons (FX600-GLN and FX700-GLN).

So far I've been very impressed with my GameXStream 600,
especially with regard to voltage stability (none of the rails flinch,
even across massive load changes) and noise (there isn't any to
speak of) . The only other supply I've owned that rivaled it was
a PC Power & Cooling Silencer model from a few years back
(that cost over twice the $ and was rated at 'only' 400W).

What are you using to measure the voltage?

That's good to hear as I have a friend who bought a Modstream just
recently. Tagan and Fortron are both good. BTW, that PC P&C Silencer is
actually made by Seasonic.

12,5V is perfect on the PSU leads. You always get
voltage drop on the way to the consuming device
on the board and there it will be about 12 Volt.
Don't use the motherboard internal voltage measuring.
Use a separate accurate volt meter.
