2003 Power Supply Roundup Part II: Better Faster Cheaper

The Allied power supply was our second control for the experiment. Another power supply priced around $40, it's usually bundled with other cases.

Allied has the weakest +3.3V rail, even less than the Antec 330W TruePower. The combined rail is severely underpowered, only putting itself ahead of the TurboLink 420W from the previous page. Also like the TurboLink power supply, this unit is not capable of the advertised 400W. The +12V rail and the +3.3V/+5.0 rail (combined) are capable of only 334W total, which put it way under the advertised 400W.
Even though Allied has produced a lot of good power supplies in the past, this is not one of them. This is basically a 350W power supply with a different label, and even though it retails around $40, the product does not justify the cost.

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...
