Silverstone Zeus 750w ST75ZF Quad Rail PSU
Specification
Published: 10th May 2006 | Source: Silverstone | Price: |
The following specification has been taken in most part from Silverstone's website:
- Quad +12V rail for superior performance
- Dual PCI-E 6pin connectors (SLI & CrossFire ready)
- Industrial class components
- Support for ATX 12V 2.2 & EPS12V
- Active PFC
- Efficiency greater than 80% (max. 86%)
The following image is taken of the +12v rail layout insert included with the Power Supply:
As we can see, Priority is given to CPU1, CPU2 and VGA1, VGA2. VGA3 and VGA4 share their power with the molex connectors, which under most circumstances shouldn't cause any problems - but it really depends on how many high power consumption devices you are planning on running from the molex connectors (12v water pumps for example).
With the +12v4 rail peaking at 22a, this should be enough to power the latest generation of ATI cards (x1900xtx) even when used in crossfire mode.

Nice Jim. Looks like a real beast of a PSU 
Jesus - that is rated with twice as much power as my current PSU!
I'm liking the current idea of only needing to plug in the connections you want - leaves a nice tidy box (as the actress said to the bishop).

Coming up soon is a Silverstone Strider 600w Modular review - should be a nice bit of kit
Very nice PSU, it looks very solid and with the performance to back it up. How good were those 12V rails? Awesome review again XMS 
It also worries me slightly that 18a might not even be enough to power the latest generation of ATI cards (x1900xtx) especially when used in crossfire mode as the current draw from these cards is quite unbelievable.
120.6w according to xbitlabs if yoi wanted to know specific numbers

but all in all a good review but a way to pricy psu for my taste.

However, now that Silverstone have confirmed that they are re-arranging the PSU rails, this problem doesn't really apply.
Cheers for the linkage

We utilize a special modified mainboard that has special shunts attached to PCI Express x16 power lanes as well as we attach the shunt into additional 12V power connectors that some of the graphics cards have.
but wouldnt surprise me at all if it differers between manufactures too, some like to raise the speed and/or use faster memories for example.
do you have any thoughts of starting to measure power consumption like this ?
at present time i have no reason to believe xbitlabs measurements are off, i looked at them before i bought my 7800gt and come to the conclusion my psu could manage the extra load and it has, flawless.
Yes, different cards with different stock speeds and different cooling solutions will change the power draw slightly. For example some pre-overclocked cards use slightly higher voltages on memory/core to achieve the stability. Also on the x1800 series for example, different revisions of cards had either 5 or 6 phase power i believe.
As for OC3D measuring power consumption, this is not something we are planning on performing at present, but if there is a need for it then we'll certainly look into getting the equipment.
However, on the PSU side of things, we will very shortly be measuring: Power Consumption (for Efficiency), Noise and Heat. The key thing for us is making sure that all of these tests are performed under the same conditions, so results are comparable.

also interesting to know if a current psu can manage the load or not, not everyone can just go out and buy a stronger psu if problem should arise.
one simple way but not so accurate is to only measure the pcie power cable, remember some site measuring that way back in the agp days.

for psu's efficiency and noise is the 2 most interesting aspects so will be interesting to se it comming
if you havent already guessed it i chose components to minimize power usage but still be powerfull for what i do.
This was one of my fist PSU's, but I returned it for how loud it was. I remember it being amazing power though
Eguy, you're slightly off again Yours was the 650W. This is the recently released, Etasis made (650 was Enhance) 750W
