300W to 450W: 20 Power Supplies on the Test Bench

Enermax Liberty Eco 400W
Enermax has refurbished its older but very successful Liberty series and is now calling it the Liberty Eco. There has also been a bit of cost cutting on the components, but according to Enermax the performance is still the same. We had the Liberty in our labs already a little while back and it performed well. The appearance is still the same as Enermax tries to keep the gunmetal finish (the Liberty Eco is rather black) together with the golden fan grille as their corporate identity. The power supply comes with cable management, though note that the pictures are taken from the 500W version.
The inside doesn't really show anything new since it's a typical Enermax layout. The input filtering stage is as in most cases on a small sister PCB located at the AC jack. The primary side carries a Hitachi cap with 330µF and 400V. The heatsinks are rather small but still big enough to handle the heat for such a lower wattage unit.
Enermax brings the only power supply in this roundup with two 6/8-pin PEG connectors, which is great news for low and medium SLI/CrossFire setups. There are five SATA and five Molex connectors on three cable harnesses. Enermax likes to mix the connectors on each harness so that some people need only one harness to power up hard drives and optical drives. The 12V connector comes with 8-pins but splits in half if you only need four of them.

We cannot run after every brand there is and if those companies don't come to us... there are surely many more missing but we can only test products from companies that are actually interested in us testing their stuff. We had an Akasa unit before though...boboko - Sunday, January 4, 2009 - link
>"We cannot run after every brand there is and if those companies don't come to us..."I guess that is the problem with almost all review sites. And the worst thing is not that you skip the smaller guys, but that what you are reviewing is not off the shelf, it's sent to you buy a company that wants a good review. So even if they have rotten quality control, and half their stuff is DOA, you know the one they send you has been triple checked and fine tuned. Not your fault, but to me the reliability is MUCH more important than a few extra watts or a few less decibels, and there's just no way to get good data on that.

If you read the reviews here, you'd know that this assumption is false in general. AT has had junk on their bench on more than one occassion - if every supplier would do what you claim, all reviews would take place in happy bunny land where everything is dandy and no negative notion is possible. But thats not the case.Surely there will be those who go the extra mile to make their product look better than it is off the shelf, but you just cant hide every trace of incompetence and bad quality.
Much like we cant expect a review site buy every piece of hardware to test it and hope they can re-sell it without a loss.

I'm just curious why the "old" version of the Antec Earthwatts 430 was dug out and retested since Seasonic is no longer the OEM for it but now has Delta as the OEM supplier and has been for many months now.Seems it'd be only fitting that the "new" version would be tested instead of a version no longer being made or sold, except as NOS (new old stock).

If only "someone" could send it to us :] I will make sure to get new revision on time, you're totally right.sprockkets - Wednesday, December 31, 2008 - link
What were those bad things happening to the SII Seasonic PS?JarredWalton - Wednesday, December 31, 2008 - link
I believe Christoph is just saying that he's received an increase number of email messages from people saying that their Seasonic PSUs have failed. It's anecdotal at best, and it could just be a case of more people buying their PSUs and thus a small fraction that fails can still result in more complaints than before.Christoph Katzer - Wednesday, December 31, 2008 - link
Yes ;)There was a revision in the beginning that had problems with certain motherboards somehow, something to do with the "power good" signal. They've upgraded the series long time ago though.

I'd just ordered some new parts, including a CX400 about 30 minutes before I saw this article come up.Nice to see that my choice seems fairly solid.
I'm sure this article will be relevant for other people as well.
