1 out of 5 eggsReally?!

Pros: None, really.. Power requirements low, so the internal fan never runs. In that regard, it's fan-less.

Cons: Over-sized, non-standard chassis. Had to mod my case, no big deal,really.
However, two in a row were defective. The first one would drop & spike the 3.3v rail, causing the system to crash. The second one would fail to start, or intermittently shut off.
I all fairness, they were purchased as an overstock item from another (reputable) distributor, not from NewEgg. The price was attractive, but if the third one doesn't work, I'll be looking at alternatives.
This item is no longer available at NewEgg, and believe me, you're not missing anything! You can find excellent deals on many other platinum rated PSUs right here. NewEgg rocks! I'm sorry I shopped elsewhere.

5 out of 5 eggsPowerful and Silent

Pros: Great looks (nickle-plated), super-stable 12V rails (dual), LCD readout to see what's going on with temps and wattage, modular, SILENT, amazingly huge internal heatsinks

Cons: Ends of wire looming are a little raw, doesn't fit in all cases (had to mod mine a bit...didn't mind at all)

Other Thoughts: This PSU is incredibly stable, and the very, very quiet fan doesn't kick on until the temperature goes over 40C or the power draw gets high. I am running an Athlon 64 3500+ (overclocked), 2Gb of PC3200 DDRAM, a GeForce 7800GT, Gigabyte K8NXP-SLI mobo, Zalman 7000b-Cu CPU cooler, two optical drives, two hard discs, a Creative LiveDrive unit, Thermaltake X-Ray, Sunbeam Chromatic Windmill fan controller, cathode tubes (three), and seven (yep, that's 7) case fans off of this bad boy. My power draw rarely goes over 135W. I can fire things up and watch the LCD display, and the 12V rails never even waver. I like this PSU even better than my previous Enermax. And with the beefy looks (and external radiator), people are always amazed and asking, "what is THAT?" It's an impressive piece of equipment.

5 out of 5 eggsSilent power

Pros: Very stable power and it is super silent. Running this power with 7900 GS video card, AMD 64 3400+ processor, and 4 HDD. I am very satisified with the performace.

Cons: The size is a little bigger than normal standard power supply.

5 out of 5 eggsquiet power supply

Pros: It is a very quiet power supply, i have it for more than 8 month now, it is a very quiet power supply, and the modular design, and its look good. LCD is not very effective since it is inside, but it is a good thought. Nice power supply i recommand it.

Cons: warning, I try to install it on my orgianl case, but seems like this is bigger than a standard power, i put it in my new thermaltake case, it fit in right there.

3 out of 5 eggsHad a defective one; died after 3 weeks.

Pros: Looks good. Ample power when it works. This was my first experience with modular cabling; I'm impressed with the loads of cables included with this guy. Will likely handle any configuration you throw at it so llong as it's not defective.

Cons: The fan needs to run more than anticipated, which is a real caveat since the fan in mine began making annoying clicking noises and eventually died two days later. As a result, the temperature shot up to around 80C. Raised temperatures in the case significantly for ambient temp, CPU temp and HDD temp even when functioning fine.

Other Thoughts: I am guessing I just had a bad one; the concept is solid and it did perform well for a brief time. For the price, though, I would hope for more stringent quality testing. Bad PSUs happen, though, I suppose; however, this is the first PSU I have ever had go down due to failure so quickly and I obviously can't reattach the metal I hacked off the back of my case to acommodate the copper sink. It should be noted that I purchased this from a local retailer as well and not via Newegg.

2 out of 5 eggsUnable to produce more than 120W

Pros: Very pretty, and enough copper to keep it cool with minimal fan use.

Cons: My Unit would fail when my system needed more juice. The highest wattage I saw it produce was 120W.

Other Thoughts: While my unit did not live up to it's specifications I did not get any useful information from the parent company with repeated emails. All they would tell me is that the warranty is voided since I had to remove the flimsy casing to the radiator because it wouldn't fit in my ATX case. They just washed their hands of me and left me high and dry.

5 out of 5 eggsVery nice PSU

Pros: -Temp monitor
-High quality
-Quiet

Cons: Not a con per say, but it would be nice if you could switch the light off in the back. It's not too bad though... Plus I knew it was there before I bought it so I won't take any eggs off.

Other Thoughts: Wow. This thing really seems like a high quality piece. I knew it was going to be a little big. The width almost 2mm too big. The depth was fine, but I needed to remove a support brace on the inside of the case. This was made perfectly clear before the purchase to I has the cutting tools already on the table when the case came in from Newegg. Great power supply!

5 out of 5 eggsCan mod the display

Pros: I already reviewed PS earlier, but I've been playing around with the cooling and the fan doesn't kick in until the ambient temp of the PS is over 40C.

Further, you can mod the display and move it out of the PS. I'll post a howto on carver dash family dot com.

Cons: Large size

4 out of 5 eggsQuality - You get what you pay for

Pros: - Very quiet
- Cool display shows PS temp and realtime watts used
- Lifetime warrantee
- Heatpipes really work; radiator on back dissipates heat quickly

Cons: - Grill around rear radiator is flimsy; handle with care
- As other reviews have mentioned, it's a little big. I had to install it from inside the case, but did not have to do any cutting with a Dremel

Other Thoughts: Overall I'm very pleased with this unit, that replaced my Coolmax 480w fanless PS that died after a year. It seems to run cooler and is very quiet, which I need for my nearly fanless PC (used for recording applications).

4 out of 5 eggsThere is a fan

Pros: Quiet - Extremely so in a fully cooled case
Modular - Cabling is nice

Cons: There is a fan. It ramps up depending on the temperature, this is not a fanless PSU. It does not run at temps around 20C though.
Large Size requires cutting of most cases, not a big deal though.

Other Thoughts: The PSU is large, my machine is silent at startup, but since I'm water cooled, my case has no other fans and this is causing the PSU to run at around 44C with its internal fan running most of the time. Even with the fan its quieter than my zalman.

The display is nice, I'm thinking about modding it onto my front panel where it might be a bit more useful.
