4 out of 5 eggsSo far So good

Pros: Quiet
plenty of cables

Cons: Size - looong.. it ended up covering the opening for my case's cable management. It still fit but was more snug than it should have been

Fan size - not necessarily a con but the fan at 140 mm doesn't site over the filtered intake for my case. I have to flip it over so that it draws air from within the case. This makes it so that it is drawing in warmer air. One the flip side the fan for the VC is just above it. The 2 are causing a nice little vacuum for more air flow.

Other Thoughts: I had to get this from a local store since my ps went out saturday night and I work from home. It was on clearance for $65 so I really couldn't complain about it. So far so good. I will come back and update once I have had it for a longer time frame.

5 out of 5 eggs

Pros: Its a Great Power supply ive never had Problems out of it such as mechanical failure.

Cons: The only things i dont like are the Size but as stated by another that comes with the power and it does make a squeel noise when powering down but ive never had any problems with it or it hurting anything else.

1 out of 5 eggsAvoid this product

Pros: Quite and modular

Cons: Voltage is all over the place, causing system instability, blue screens etc. It got to the point where my system would not even power on and I would have to unplug and replug AC power 2-3 times. Finally the MB would come out of standby mode. I thought the issue was my MB but thankfully tested with another PS and that was the problem.

Other Thoughts: When I originally purchased I talked to support about the voltage drifting and a squeling noise. They said it was normal and if I wanted I could pay to ship it to them and wait for repair.

Hard to get ahold of support or get a response. Would not recommend any of their models!

1 out of 5 eggsExpensive junk

Pros: It is modular is the best that I can say.

Cons: The unit lasted less than 3 months before it died with no notice. The 12V rails just ceased operation while the 5V continued.
I have to pay the shipping to return defective product to the manufacturer as though it was my fault that their products are defective.

Other Thoughts: Fortunately the failure didn't take out my brand new Asus P8P67MB and I-7 CPU as others have found happens. Zalman assumes no responsibility for damages caused by their products failures.

4 out of 5 eggsGreat deal at $100, but QC is lacking

Pros: Lots of power with 80+ cert and a 3 year warranty.

Modular cables are always a plus.

Very quiet. (As long as nothing blocks the fan)

Cons: Immediately after installing, I noticed an internal zip-tie was positioned poorly and rubbing against the fan. It was a quick and easy fix, but I'm surprised it made it out of the factory with such a blatantly noticeable and silly flaw.

The length, but that just comes with the power.

Other Thoughts: I'll be running this against my 2 Corsair TX-series PSUs over the next few years and I'm curious to see how they stack up.
