The Enermax Liberty - Getting long in the tooth, but still worth a look

Intro
Today we will be looking at the Enermax Liberty 500W power supply. Liberty? But that PSU is two years old! Yes, as a matter of fact it is, but since its release a few years ago it has served the community well, providing stable power and low failure rates. We thought it would be worthwhile to take a look at it and see how it compares to some of the latest and greatest PSUs we've been reviewing. It's still a very stable offering, and users running such a power supply will hopefully be able to determine whether or not they need to consider upgrading anytime soon.
Enermax has been in the power supply (and case) market for ages, and anyone who has taken the time to build and/or mod a PC in the past decade should already be familiar with the Enermax name. When they were founded in 1990, Enermax was one of the first companies to begin selling retail power supplies to the market, helping to bring us to where we are today. Over the past few years we've seen a tremendous growth of Enermax products, particularly when it comes to introducing new technology and being the first to market with new standards. Enermax has built up a successful team over the years with branch offices and warehouses around the world. Their headquarters are located in Taoyuan, Taiwan.
The Liberty was designed with cable management as one of the features, which continues to provide good flexibility two years after purchase. The discussions around the web about voltage drops caused by the modular cable design and the extra resistance that can create do not seem to be a problem for Enermax - they continue to design current models with modular cables. Enermax promotes the flexibility of cable management in their advertising, and it is said that you can run a decent high-end system with the smaller 400W Liberty and a few extra cables. For people who own a Liberty power supply that are looking to upgrade, they don't necessarily need to buy a new power supply. A few extra cables will be enough to run many newer systems as well. The 500W model comes with two 12V rails supporting 22A each - plenty strong for all but the most demanding configurations - and we will see later that their OCP is even a little higher than stated.

Disappointing once again to note lack of ripple data despite indication in the "Test Methodology" that ripple details would be provided for PSU reviews.Voltage output with increasing load is one consideration; cleanliness of voltage (ripple) is another issue.

hey can u guys review corsair's HX620/HX520 psu? They're supposed to be kickass and im just curious how they'd rate compared to the psus u've reviewed. Thanks and keep these great reviews coming!wolfman3k5 - Tuesday, July 31, 2007 - link
I'm sure that when they'll run out of stuff to write about (again), there will be a review about Corsair 520HX/620HX. Or maybe 2 years from now, who knows. They never wrote a review about the Enermax Liberty either back when it was "cool" to own one. Like I've said before, they do write PSU reviews only when they run out of stuff to write about.Cheers.

It is precisely because of unneccessarily nasty angry posts like this, that, after 8 years, I dont post on AT forums anymore, and haven't for about 4 months so far. I just visit for the articles now. However, it seems I cant even escape this immature trash talk even in the review comments.I have been a member of many forums - ars, Hardforum, abxzone, i4memory, xbit, techreport, xtremesys etc., all for the most part friendly co-operative back and forth type situations there. But only on AT do we see the anal retentive crowd post again and again what they dont seem to understand is hurtful (to the staff in this case).
Well, I like the PSU reviews, and if I were a mod, I would ban you permanently in a heartbeat. And if you like jonny guru so much - then go to his site, and keep your big mouth shut here.

Thanks - I'm sure Christoph appreciates your comment!As for the reviews, you may have noticed that we didn't do ANY PSU reviews for a long time. Christoph is a new addition who is busily cranking out reviews. As with pretty much all of our content, we review what we're sent, and when people asked for some more reasonable PSUs he reviewed an Enermax Liberty 500W. There are, unfortunately, only so many hours in a day and so many PSUs in the lab, so I am not aware that Christoph has a 520W HX to review. Maybe he'll get one in the near future, maybe Corsair will send him something else, maybe they won't send units to Europe and we'll never get a review of one done. At some point, though, we need to establish a starting point and move forward, and that's what we're doing.

You all might wanna check out jonnyguru.com for a decent PSU review...yyrkoon - Tuesday, July 31, 2007 - link
I own, and think I would still prefer to own my Antec EA500 for much less. I keep hearing people putting Antec down for shoddy PSUs, but I own this EA500, and previously an Antec 450 SL, and have nothing but positive things to say about either. One of my friends however does sware by Enermax PSU's, but I think if I were to pay this much for a 2 year old(outdated) PSU, I think I would just pony up the extra for a PC Power & Cooling Silencer 610 EPS12V(they are only another $40 usd . . .).Efficiency is one thing, and rock solid rails are another . . . We all know (or should) that Antec usually makes a decent PSU, Enermax does make a decent PSU, and that PC P&C(Seasonic) makes the best. Granted, anyone can put out a lemon(and sometimes that lemon is part of a 'run' that are all lemons).

The "Lemons" you refer to are pretty much all of the Antec TruePower and SmartPower PSUs due to their use of fuhjyyu capacitors on the secondary side - they have a pretty much complete failure rate - I personally own 4 antec truepower II powersupplies and so far I've opened two, and so far both have had this problem, and I'm not even slightly aloneyyrkoon - Wednesday, August 1, 2007 - link
Actually, then lemons I refer to happen with ALL namebrands, and why you would purchase a known bad PSU based on its capacitors is un-bewknownst to me ...Spikke - Monday, July 30, 2007 - link
I have the 620w Liberty and have owned it for nearly 2 years now. It started out on a Gigabyte K8N SLI-Pro, 4200+ X2, 150gb Raptor, 500gb Caviar, and 2x 7800GTX in SLI. It's now powering my new rig just fine Gigabyte P35-DS3R, E6850, 150gb Raptor, 2x 500gb Caviar, and a 8800GTX. It was a great purchase and I have not had a single complaint or problem with it in nearly 2 years. I would definitily not hesitate to buy another Enermax psu.
