Testing Silverstone ST65ZF

The final power supply we're going to take a look at is a Silverstone ST65ZF.

The 12V leads for the PCI-e connector are located behind all of the other leads, behind a OCP module, in between a bunch of capacitors. There's only a few things more nerve-wracking than blindly shoving a steel tip DMM probe into a live power supply. Kids don't try this at home.

The Silverstone proved some very interesting results. The drop in voltage from the power supply's main PCB and the load was as much as the Ultra X2 550W modular power supply. And the .02V drop between the peripheral connector and the load is actually more than any of the other power supplies tested. All of the other power supplies only showed as much as a .01V drop between either side of the connector.

On the next page, we're going to look at graphs of all of the power supplies and how they did during each load test.
