As we can see, there was a definite separation between different power supplies. Most notable were the Enermax power supplies, The Fortron and Zalman 400W power supplies, and the TurboCool 475. All of these kept the memory from producing even 2 faulty flips over a 6 hour period. This came to almost no surprise to us, since these power supplies were the most shielded and heavily constructed of the bunch.

1. No amp measurements were listed, a serious deficiency because without them there is no way to know how well each PS met its amp specs, and many brands are known to fall short.2. No overload testing results for shorts, excessive power draw, excessive temperature.
3. Ripple is not just slow voltage variation also short term variation, such as for each AC cycle (60 Hz for the incoming AC, about 60,000 Hz for the output DC). I would have liked to see how the latter correlated with the memory noise test results.
4. I hope you were careful when you tested the PS heatsink temperatures because some heatsinks are live with high voltage.

Well for the observent people who can differentiate between orange and blue, its not an issue. Also waiting a full second before clicking it reveals the location on both the bottom left and the mouse cursor. but i can see how it does get annoying.Anonymous User - Thursday, July 31, 2003 - link
yeah those in page advertisements are REALLY annoying...those have got to go. i never know when i'm going to link to another anandtech article or to an ad...i guess that's the point but it's still unacceptableAnonymous User - Thursday, July 31, 2003 - link
I would like to see the review include a Heroichi Electronic power supply, I hear they are very good but I haven't used one.Anonymous User - Thursday, July 31, 2003 - link
Some of your "In Page Advertising" links seem to be missing closing links tags or something so that it results in having a <link> in the middle or end of a sentence. Ex. "We had a lot of troubles with Vantec’s last power supply, the Stealth. We found an error in the production label<link>, which quickly led to a change in all the labeling on all Stealth power supplies."KristopherKubicki - Thursday, July 31, 2003 - link
#3 and #4, thank you for spotting these errors. I have updated and fixed them.Cheers,
Kristopher

I hope the ripple for the PC Power & Cooling 3V wasn't 2.295.. Possibly 3.296??? 1 volt drop is unacceptable.Anonymous User - Thursday, July 31, 2003 - link

a little more content per page in some cases would be nice too......but good to see content on the site at all...and seemingly more regularly too...

woah guys, the tables need some work...
