2003 Power Supply Roundup Part II: Better Faster Cheaper

The EG465 power supply did extremely well in our last power supply roundup. We have not really seen many other new products from Enermax in the last few months, so we obtained a slightly newer version of the supply we reviewed in our first review instead.
From our previous review, you may recall the EG465 PFC’s tight tolerances and excellent features. The new version sports all of these features, but since the slightly different circuitry warrants a separate benchmark for this PSU. The variable fan control, motherboard monitoring and copper/rubber ATX sheath are all included on this power supply. Furthermore, the line we looked at also came in a glossy finish similar to the TTGI units. The unit includes Active PFC as one of its features as well.
The EG465 also comes with Enermax’s trademark variable fan control on the rear of the unit. We have not had problems with Enermax’s variable fan controls. The dial-style fan control assures that the switch can never fall into a halfway position like with Vantec or TTGI. We will touch more on this issue later.
One annoyance the EG651 and the EG465AX both had was a loud “pop” when the power supply was turned off. This occurred whether or not the motherboard was on or not.

This power supply is really a system builder’s treat. All rails seem to be pretty evenly balanced, with plenty of room on the +3.3V and +12V. The +12V rating appears to be the peak, however. A higher combined rail rating would go a long way for this power supply, but we are just nitpicking rather than criticizing these specifications. When talking to Enermax, one of the features they were very proud of was their strict adhesion with the Intel ATX12V 1.2 standard. Of all the power supplies we looked at, the two Enermax units were the only power supplies which displayed this ATX12V 1.2 compliance. We will see this certainly pays off in the performance benchmarks later on.
Unfortunately, with any quality component, the EG465AX-VE is expensive. Most vendors carry the unit for about $85, which prices it aggressively for system builders. We were very pleased with the performance of this unit, as well.

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...
