Silverstone Zeus ST65ZF Author: jonnyguru Date Posted:26/07/2005 04:28.22 SLRating: Bottom Line: The Silverstone Zeus ST65ZF is HARDCORE. It's more power supply than most people need, but if it's in the budget and you want no holds barred, this is a power supply for you.

Testing

Testing a quad rail power supply on an ATE tester made for two rails provided me with a unique challenge.  I knew that I could plug multiple rails into a single load and that the load would divide amongst the rails, but how do I control that division of load?  Resistance.

Creating resistance between the load and the rail was easy.  I would just provide less leads to the load if I wanted less load on a particular rail.  But how do I determine how many leads I need?  A Fluke 336, of course!

Ok.. Now I'm just bragging.  But if you want a good multi meter, the Fluke 336 is a good place to start (yes, there's a model above it.)  Not only is it a True RMS multi meter with a "hold" button and a light, but it also has a clamp-on ammeter.

On the left, the Fluke is measuring the amperage on the 12V3.  The ATE has an 18A load on the 12V1, but the power supply's 12V3 and 12V4 are both plugged into it.  In the photo, the Fluke measured 10.9A on the 12V3.  The other 7.1A was measured on the 12V4.  On the right, the Fluke is measuring 9.2 on the 12V1.  It also measure 8.8A on the 12V2.
