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.

Under Load
With the Fluke telling
me what each load is on each rail, I could proceed with testing. So
now let me break down for you how I'm going to test this unit with
my trusty load tester...

The first three tests
are pretty "normal." The fourth is pretty much balls
to the wall.
Now that you know
how I'm going to hammer the power supply.. let's go ahead and juice
it up...

The capabilities
of this power supply is downright SCARY! Even when loaded over
it's maximum rated 650W, the power supply stayed fairly cool... even
after half an hour!
The peak rating on
this beast is 710W (maximum being a sustained rating, while peak is..
well... peak.) I didn't go this high because as it is the lights in
the dining room were dimming with the nearly 1000W draw at the wall. A
bit unnerving.
Much to my surprise,
the efficiency stayed good too! Under "normal" loads,
efficiency was consistently over 75%. Even when pushed to the
extreme, the power supply maintained an efficiency > 70%!
The insides of the ST65ZF is beautiful. As if someone with OCD designed
the layout of the PCB. I've never seen a power supply laid out like
this.
I've seen neater wiring, but the problem here is that the wires come in
to the housing on the opposite side of where they are soldered down to
the PCB.
The heatsinks are absolutely MAMMOTH. And they need to be with the amount
of juice this thing puts out.
