Testing
As usual we are testing with our Chroma programmable loads equipment to fully load each rail to a specific amount. This is important to get truly accurate results and not merely approximate values. The tests are conducted in two different temperature environments. One is normal room temperature of 25-26°C, while the second environment goes from room temperature and increases steadily up to 50°C. Especially during the higher temperatures we will see how good the power supplies are and what they're really made of. Components inside will perform much worse at higher temperatures, but we expect any good quality PSU to deal with such test conditions without failing.
Note: If you would like to know more about our testing methodology, equipment, and environment, please read our Power Supply testing overview.
3.3V DC Output
The 3.3V rail is the worst performing rail on the G1 power supply. It has a steadily decreasing voltage drop but does stay within specifications fortunately. Before sending us the samples the marketing people at Zippy expressed a little concern about the high temperature test environment, since their PSUs are rated at only 40°C. (We have to add here that most companies are rating their power supplies at just 25°C, so Zippy shouldn't have been concerned at all.) Temperatures didn't actually affect the results much, however, as even at room temperature we see similar performance from the various rails.
5V DC Output
The 5V rail looks better and maintains a relatively steady output. With a range of 5.00V to 4.88V the 5V rail can be described as very stable. We might like to see the voltages shifted up 0.05V, but it's not really necessary.
12V DC Output
We weren't surprised to see the most stable 12V rails of any PSU we've tested so far - a clear indication of Zippy's server PSU roots. It doesn't matter what temperature, input voltage, or load use with this power supply; it gets to work and always delivers an extremely stable 12V output. The lowest output we measured was just 11.83V at 50°C and maximum load. We have not seen better results so far.
5Vsb DC Output
The 5Vsb rail has good results over the range of loads. It starts out somewhat high (which is usually considered better than being low) and at the highest load we had just a few millivolts less than the ideal.

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,
B.

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.
