Dirkvader Zalman 600W Review

Found this review of the Zalman 600W last night, which includes a top down shot of the innards:

What I find interesting is that the PCB seems a bit different than the Epsilons and OCZ GXS units, but is still definitely based on that design. Also interesting they chose to bolt the heatpipe to the output side only, leaving the other two heatsinks to be fan cooled. Not sure how effective that heatpipe will be, what with the high efficiency the Epsilon design operates at.

And from SPCR a review (http://www.silentpcreview.com/article688-page1.html).
Based on Fortron.
2. VOLTAGE REGULATION was excellent; by our usual tests, none of the lines fluctuated by more than 3%. Even under crossloading (imbalanced loading), with the 12V lines on maximum load and the 5V and 3.3V lines on just 2A, the voltage regulation was excellent.
3. RIPPLE

Ripple was well within the limits specified by the ATX standards. The worst ripple occurred at maximum load, where the +12V ripple reached 18.5mV. To put that in perspective, the ATX12V spec requires +12V ripple to be below 120 mV.
5. LOW LOAD PERFORMANCE

Standby and no-load performance were both reasonably efficient, with standby coming in well under one watt, and no-load under 10W. ZM600-HP had no issues starting or staying powered on with no load applied.
6. LOW AC VOLTAGE PERFORMANCE

The Zalman ZM600-HP stood up to the drops in AC voltage admirably, even when operating well below its rated input voltage of 100V. Neither voltage regulation nor ripple changed measurably during the test, and efficiency dropped only marginally under the most severe conditions.

It seems that is a very good PSU.

Interesting that the ripple is that low on an Epsilon based unit.

Could it be FSP figured out the problem?

Could it be that OCZ adopts this "fixed" version of the FSP Epsilon?

I might have to get my hands on one of these and check the ripple for myself. :D

Look at the caps in the pic - them's are Teapos. They look bigger too :)

[jonnyGURU]

Ah!

I believe you're correct!

So it seems that the problem may have been fixed!

Did OCZ get in on this?

[Oklahoma Wolf]

We can hope :)
