Zippy Gaming G1 (GSM-6600P): Hybrid or Fence-Sitter?

- Cases/Cooling/PSUs
Primary Side
The inside looks like your typical PSU. Zippy has all of the components of the transient filter stage located in the upper section of the PCB. It looks very crowded and the fan is located directly behind it. The filter stage however looks very good and includes all the expected components.
On the side we see a small Hitachi cap with 330µF and 400V which is rated up to 105°C. The PFC IC is located on the left side of the primary stage.
Secondary Side
The secondary side has another PCB that contains the circuitry for PWM and fan control. The whole area is quite packed and includes a cable-jungle so there is little chance for any airflow to these components. This area will most likely get hotter than the rest of the PSU. The fan is located on the other side along with the heatsinks, and that's where most of the airflow will be present.
One important issue to point out is that the cables are not in any way connected to the housing which makes them quite unstable. If you carry the PSU do not grab it by the cables - not that we would recommend doing so anyway - since there is a slight chance for them to become disconnected from the PCB. Zippy should have attached the cables to the housing with at least a cable tie, just to be safe, and that is a solution that could still be easily implemented.
The Fan
The installed 8cm fan is manufactured by the Japanese company Sanyo Denki. They have very good fans and are famous for high reliability, low noise (not this model), and a good amount of airflow (CFM). The fan pulls the air through the power supply which can potential provide for better control of the airflow. However, a drawback to such an approach is the higher noise levels because the fan is located right at the exit. Etasis power supplies have a similar design, but their fans are installed a bit further inside of the PSU, so they get the pull arrangement for airflow along with lower noise levels.

I wonder if you guys have access to 2900XT's and a quad to actually test this unit?I would have to disagree with you on comparing Seasonic to Zippy. Most currently available data suggests that Seasonic won't match up in terms of voltage regulation (ex: 's data and JonnyGURU's data).
Lack of connectors can be a shortfall, but I'm not sure if anything else really matters. I suppose we are looking at things from different perspectives. From an Engineering standpoint, I love the Zippy. That is how I look at things. EMI, good surge protection, resonant Q-Filter on the input, an MOV ... and everything else that leads to workhorse performance is how I look at it.

Just turning off the highlighting (white text).Bjoern77 - Friday, August 3, 2007 - link
It's nice to see some different power supplies tested, and not again a Infiniti 720W test ;)(though i'd appreciate a 650w infinity test, since i'm currently choosing between the 650W Infiniti and the Seasonic 650w Energy plus)
And i wish Anandtech would put out reviews and guides at at least half the speed you do - ok, a bit unfair, since you review one by one.
Keep going,

Well, no one can say this review has a sugar coated conclusion - lolIts nice to know you can tell it like it is, even tho you are reviewing a unit that Zippy themselves sent, not one that you purchased retail.

Good review, really do appreciate it. This is the kind of product I like reviewed, not Enermax 500 Watt PSU that anyone can get their hands on. Heck, even the shop down the street from me had Enermax Liberty PSUs in stock. Zippy makes decent enthusiast/server PSUs, how ever I prefer to stick to my PC Power & Cooling Quad 750W. Keep up the good work guys, and thanks again for the review.Talcite - Friday, August 3, 2007 - link
I love how you guys have these new reviews on the PSUs but I sure miss the oscilloscope readings that other sites have posted. Is your chroma tester capable of also putting one of those out?None of your graphs realistically depict spikes and sags in the voltage, only the average obtained in the long run. I was under the impression that the ATX specs require PSUs to be within a specified range for both sustained voltage changes and instantaneous voltage changes.
