PC Power and Cooling 510 SLI

I got one of these pups recently and popped it in. It replaced my OCZ Modstream 520w which went to my back up rig.
First, I have to say that I now remember what I liked about modular power supplies - so many cables! I only need like 3 out of the 10. Anyway, measured the 5v and 12v rails and they were 5.12 and 12.09 respectively at load. Both well within 3%. At idle there were the same as load. Very impressive.
tested during startup/shutdown
12v = 12.08v-12.11v mostly @12.09v & 12.10v
5v = 5.11v-5.13v mostly staying on 5.12v
Sweet

I want one too......
Have you checked the 3v rail??? (orange cable)
Sweet indeed!

Measured with a multimeter?

No, it's such a PITA and if the other ones are that solid I see no reason to doubt the other.

Yes. I don't trust volatges reported by software (and neither should you). Case in point, ITE Smart Guardian reads the following:
12v = 11.83v
5v = 5.05v
CPU = 1.53v (it's set at 1.595v and measures at 1.6v).

I don't, just making sure you didn't either.
Seeing all the voltages consistently higher than the rail ratings surprised me mildly. It makes sense though, small extra amounts of voltage like that isn't likely to hurt anything, and could potentially help stability on iffy hardware. Stability is the important thing anyway, especially with adjustable pots.
Funny thing though, ITE shows similar wrong voltages for my quality PSU on the same mobo, 5.05V on the +5.0V rail and 11.71 on the +12V rail. From what I've read, other people have similar results... you'd think motherboard manufacturers could do a better job of calibrating their sensors. Oh well, poking around with multimeters is fun.

the components on your mobo are spec'd to run within a 10% variance in voltage
Anything over ~5% can cause instability when overclocking.....
info found from "e=mc2" over on XS forums

I wonder how my powerstream 600 would fair?
I've heard some bad reports......but mine isn't the SLI version, So if I go SLI i will have to use a PCIe adapter....and according to that article splitting the power draw can fix any probs......
FZ1 -> Does that PSU make much noise?
I was thinking of giving my antec psu to the next rig I build for someone and tranfasing the OCZ psu to the intel rig......But I need a quiet PSU for the AMD rig.......I was thinking of Silverstone but.......? (if i even do this.....it all depends on IF I go SLI.....but you know me, once I get an Idea....)
:eidt:
The IHS comes off 2nite!

Honestly, It's hard to discern with my fans and waterpump going but it appears to be quiet.

But your rig doesn't even chew over 400W at maximum load.
I suppose you could compare load vs. idle voltage
difference against your original PSU to judge quality.
The voltage value you get for each rail through multimeter is irrelavent as you could always fine tune the pots inside quality made PSUs anyway.

SLI config's can pull amps and amps of power......if both cards pull from the same rail it will crash..........

Just slighly above 56.7W to be exact according to
Xbits for his
single mildly OC'ed 7800GT.

It's not the overall power usage that's the problem.....
It's that most new PSU's have 2x 12v rails.....When you run SLI/XFire then the 2 cards could pull all their power off the same 12v rail....this rail may not have enought AMPS to supply them......If you combine the total AMPS of the psu (using 2x 12v) it's enough, but one 12v rail is for the mobo....
On the PSU FZ1 has it has 1x 12v rail supplying all components....
I thinks this is only a prob with ATI's current cards anyway.....the GForce 7 series doesn't use as much power...
