OCZ 600w vrs Zippy/Emacs 600w

[drewmister]

Ok I need to know a little about PSU rails and the dual 12v rails
what runs off 3.3 rail?
off 5 rail?
off 12v rail? (mobo / cpu, but is that it?) Still don't understand the dual 12v thing....

I was looking at both the OCZ 600w and the Zippy 600w and can't seem to figure out which one is better. (Well my eyes definately like the look of the OCZ like a million times more as the OCZ is beautiful and the zippy is not only not beautiful, but ugly)

The difference I noted is
-OCZ 3 rail is 28A while the zippy is 30A
-OCZ 5 rail is 48A while the zippy is 30A
-OCZ 12v1 is 20A and 12v2 is 18A and the zippy 12v1 is 26A and 12v2 is 20A

This will be powering a new a64 3500+ on a dfi board (when released) a 6800 ultra, 74gb raptor, water pump for water cooling, 3-5 120mm fans

I know these are both overkill, but I have the money and want a good future proof PSU... the zippy is 20 bux cheaper than the OCZ at the moment...

I apparently know nothing about PSU's... There are two versions of the zippy 600w and the one I listed is $185

While searching I found this thread.
http://66.102.7.104/search?q=cache:...thread.php?t=792566+zippy+600w+ocz+600w&hl=en

And realized that there was this 600w zippy for $254

and only difference I could find was the single 12v rail verse the dual...
Another thing mentioned in the above thread was that the OCZ 600w has been on recall due to damaging video cards?

There was a small recall of a few OCZ 600w units due to shipping damage, but that's the last I've heard of it.

The Zippy units are intended for the workstation/server market - they all have one fan and will tend to get a bit loud. That said, the build quality of them is on a whole other level from most PSU makers - everything is tested and rated at 40 degrees on them. There just isn't anything better out there from a build quality and reliability standpoint.

However, the OCZ should be more than reliable enough for your needs, and will be a lot quieter. OCZ's warranty is good enough to make up for a whole lot. I would say just go with the OCZ unit.

Whats the benefit of the dual 12v rail?

 

[Pro*Banshee]

more stability with high-wattage demands.

like if a few opticals spin up and suck down a lot of 12v, the other rail remains stable to keep something else like the CPU stable so the system doesnt crash

 

[drewmister]

according to avid6eek over at pcstats dual 12v rails is disadvantageous...

His argument being one of if cpu only uses 18A on rail 1 that supports 20A then the other 2A is useless and if you need 22A on the secon rail that supports 20A it won't work... whereas if they were all on one rail it would...

seems like a valid argument...

And I disagree with him to an extent - having the CPU power supply seperate enables more stability when one is using the other 12v line to run video cards from. Unless you're trying to run pelts, no system I can think of would overload a dual 18A 12v rail system; which is about the highest rated of the dual rail units I can think of (not made by Zippy that is).

OTOH, if you are running pelts from the same PSU, that might be a reason for a single massive 12v rail.
