FSP Group ZEN 400 400W Fanless ATX 2.2V SLI Certified CrossFire Ready 80 PLUS BRONZE Certified Active PFC Power Supply

Pros: -

Cons: -

Other Thoughts: it's a part of the previous review - I wanted to add video to show the reason (bad condensers)

Pros: Good looking, silent, stable.

Cons: Died in 4 years - warranty 3 years.

Other Thoughts: I have another one I bought 1 year ago - will see how long it'll last.

Pros: Silent. Stable. Worked for over a year now without a single problem, in a case with so-so ventilation still cool to the touch.

Cons: Took off an "egg" for not being modular. That's very useful in a minimalist case. But as long as you know what you're getting, it's still a great PSU.

Pros: Dead quiet, high efficiency, VERY reliable! I have mine in an nMediaPC HTPC case that sits in the sun a great deal of the daytime. No heat related issues... No issues at all! It's been a flawless performer throughout all circumstances.

Cons: None.
Some say price is a con, but silence is golden. I paid half again as much nearly a year ago and I'm still happy.

Other Thoughts: Surprisingly heavy, but it makes sense that heat sinks would be heavier than fans.
Works fantastic in my HTPC:
nMediaPC HTPC 6000S case, Intel DG45ID MoBo, 2.66GHz Core 2 Duo, 8GB RAM, 64GB SSD boot drive, and Bluray burner. This is a great TIVO HD companion because it can transcode .tivo files and burn them to Bluray.
Thinking about a 3rd HTPC and if I don't go for an Atom/Ion I'll buy another of these for the next system.

Pros: Absolutely quiet. Perfect for a DAW or other audio-oriented PC.

Cons: Generates a lot of heat - make sure your case has *excellent* passive ventilation or expect to add a couple of (quiet) case fans.

Other Thoughts: I'm running this in a 3U rack case along with four SilenX fans and you can barely tell when the computer is on...sometimes I actually have to check for the power light.

Make sure 400W is enough.

Pros: I bought this power supply in April of 2007 while building a passively cooled silent system. It has worked flawlessly since then.

I'm no longer running a silent, fanless system. In fact, I've replaced virtually all the major hardware components since 2007, but this power supply remains.

To give you an idea of what kind of load the power supply handles, I'm currently using it with:

* AMD Phenom II X4 3.0Ghz (95W) CPU (stock HS/fan)
* ECS GF8200A motherboard
* 4 GB DDR2 800 memory
* Radeon HD 4770 PCIe video card
* 16x DVD-R
* 250 GB Western Digital SATA II hard drive
* 500 GB Seagate SATA II hard drive
* Four USB devices (scanner, printer, wireless keyboard/mouse, wireless NIC, USB hard drive)
* two 120mm case fans

Cons: Kinda pricey.

Other Thoughts: It's expensive, but it's been rock solid reliable for me-- not to mention dead quiet!

Now that I'm back to running a traditionally cooled (read: loud) system I'd probably go with a cheaper fan-cooled power supply today. But if silence is golden to you then this power supply is worth the extra cost.

Pros: This is the only fan-less power supply on NewEgg, where is the competition. Had no problem installing, cables adequate. Only 2.4ghz CPU, one disk drive and modest GPU. This is a PC HDTV hook-up and needs to be quiet.

Cons: Need more selections, where is Antec?

Pros: Quiet. Reliable.

Cons: One sata connector split lengthwise into two. This sorta mars an otherwise blissful experience.

Other Thoughts: I repaired the connector with tape. This is not something I expected from a costly PSU. PSP, how about spending a few extra pennies on better plastic? i probably will buy a different brand next time.

Pros: SILENCE! ... passive cooling, and yet it doesn't really get that hot. This thing is perfect for my home file server. Cables are braided nicely and have plenty of length to them.

Cons: It's heavy, yes, but not heavy enough to make me worry about my case failing to hold it. Modular cables would have been cool, but it's not that big of a deal for my application. I wish there were more passively cooled PSUs out there.

Other Thoughts: Used in my energy-efficient, low-noise home file server running Ubuntu.

Pros: No noise

Cons: Too heavy. Too expensive. No Zen at all.

Other Thoughts: It would be nice if things were really what their names meant. Of course, knowing Zen probably precludes buying this particular PSU.
