Set your power hungry system free with Enermax’s Liberty 400W PSU. This modular PSU is designed to deliver maximum power with minimum heat. Instead of a small fan on the back of the unit there is a 120mm fan on the bottom and the back panel is a minimally restrictive hexagonal mesh interrupted only by the power connector and switch.

The modular design makes cable management easier. The main power cables are permanently attached while all of the peripheral cables all plug into the back of the PSU. To make installation easier the PCIe cables are color coded. The cables are all wrapped in mesh for a cleaner installation. Extra cables can be stored in the provided bag until they are needed.

5 out of 5 eggsStrong, stable, and quiet since 2006

Pros: Duel 20 amp 12v rails.
Quiet.
Stable.
Modular.
Nice cables.
Looks nice.
Easy to clean.

Cons: it gives 600W PSU envy

Other Thoughts: Right now powering Xeon X5460 at 3.8ghz on a DFI P35T2RS, an R9 270X, and several large hard drives in an Antec 900 case with all fans going. 100% stable as always. I don't miss my 3770K/gtx780 either. This single individual 400W unit in multiple builds, over the years, since it was my main rig in 2006. It's been a reliable backup/extra since 2007 when I moved to the more powerful GPU lineups and have relied on an Enermax EIN720W for the more high end. That one is still kicking strong too.

5 out of 5 eggs

Pros: I've owned 3 Enermax power supplies and they have worked well. They are relatively quiet. The modular cables are convenient and work well.

Cons: This power supply stopped working after about 1.5 years running 24/7 in a tower server. I RMAed it and got back a new one after about 1 week. I wasn't happy about the broken power supply, but had am happy that the support was great.

1 out of 5 eggsUnstable

Pros: None, unless you consider modular cabling a pro. I am done with modular PSUs (this was the third modular in a row--all different brands--that had issues).

Cons: Had serious stability issues with this power supply when I tried to run the system with more than one hard drive. Constant BSOD with Windows, silent data corruption with Linux (I'll take BSOD over that any day). Problems went away with a different power supply (after a month of trial and error swapping out different components; I never dreamed a "quality" brand of power supply would cause that).

Other Thoughts: Relegated this unit to a computer with one hard drive. Seemed better than tossing it or trying to replace it.

5 out of 5 eggsAwsome PSU

Pros: Fast shipping. Excellent packaging. Works great right out of the box. Modular cables are a MUST but not needed. Looks good in black too. It's also really quiet.

Cons: None.

5 out of 5 eggsAwesome

Pros: Great PS. No issues. Fits perfectly in my mATX case, holds voltages perfectly. I like the external

Cons: None

Other Thoughts: I do wish they would include a couple more connectors, perhaps shorter ones to enable an even cleaner build. No matter, still a 5 egg product.

5 out of 5 eggsPowers alot for 400W

Pros: Powers on, and is silent as can be.

Cons: I would have liked to see the molex connectors and the SATA connectors on separate cords but this a design issue.

Other Thoughts: When looking through the reviews on newegg I noticed that nobody had tested this PSU with an 8800GT. I was afraid the 400W could not power my system, but I was wrong. The PSU powers much more than that.

My system: Enermax Liberty 400W PSU, Adata 2GB DDR 400, BFG OC2 8800GT, EVGA nforce 4SLI motherboard, 320GB Western Digital HD, 80GB Samsung HD, X-fi Creative Sound Card.

1 out of 5 eggsBad Customer service

Pros: good looks

Cons: Beauty is only skin deep. Good luck obtaining RMA in the event that you have a problem. they only responded to me via email if the info is complete and nothing by the fax... and the fax # is busy 99.99 percent of the time.

Manufacturer Response:

5 out of 5 eggsElegant and Efficient

Pros: Modular cabling, quiet even with its large fan, reliable, and it has a sleek finish. It also comes with a nice carry bag for extra cables.

Cons: None, if you're running a normal system (1 graphics card), it will get the job done. Probably would do two cards, but I haven't tried it.

Other Thoughts: You'll wince at the fact that this thing is going to be INSIDE your computer. It's just cool looking. Comes with enough cables to hook up to six IDE/SATA devices and two PCIe. As I said, definite recommend for any regular home office computer.

5 out of 5 eggsNice little PSU

Pros: I bought this to replace the PSU in my Dell Inspiron 530 so I could use a nicer video card. I went with this one because it's not oversized like another PSU I tried and the modular cabling makes it's really easy to keep the insides of the cramped case clean. While some people didn't like the "eternity" cables they worked well for me because I only need one set for my DVD, hard drive and extra fans.

Cons: The PSU makes a lovely ZAP/static noise when powered on from a cold start. This worried me until I looked on the Enermax support faq. Apparently this is normal as the PFC turns off instead of going into standby (uses less power when off!) When it powers back up it makes a noise.

Other Thoughts: The bag for the cables is cool, but I suspect it will end up buried somewhere in my parts pile.
