I decided to put a PC in my kitchen, which probably tells you that I am not married. However, even by bachelor standards, the old parts I used to build it were too noisy and unreliable. A major culprit was the power supply. That led me to the Earthwatts, which was very affordable.

After using it for a while, I have been impressed with the lack of fan sound. It is almost silent and very impressive for a power supply in this price range. By switching to a fanless video card, I was able to make a PC that is essentially silent. I actually thought that I hadn't hit the power button properly or that something was defective before the projector found the signal.

Yes, a projector in the kitchen. I will be single for life.

The EarthWatts has been pretty perfect for my needs, and I regret not putting more thought into the power supply for my main PC. I think it is a good choice if the price remains competitive. If reliability is an issue, I will update this review and start dating.

I was looking for a replacement for my generic PSU, since my system at times felt like it didn't want to power up: it seemed it didn't have enough power. I have a couple of other desktops that run off ANTEC PSUs, and I have had no problems with them over the years. After reading the reviews, I decided to purchase this one because it's got good reviews and is 80 plus bronze. I thought I could save some energy as well. It worked right out of the box with no issues and as far as power consumption is concerned, here are the numbers from my Kill-a-Watt meter:

Old system on Idle: 66-68W
System with 380D on Idle: 57-60W

Old system running at full: 100-105W
System with 380D at full: 85-90W

I believe it would have saved more power if it had a max. output of, say, 300W instead of 380W, since at lower loads, it is not running as efficiently as it is at higher ones. I am not using this particular system for any kind of gaming and I don't have a lot of cards or drives in my system; a 380W PSU is definitely an overkill. I wish they offered one with a smaller output.

My take on this is that if your system is running at more than 80W at idle and 120W at full and there are some issues with your generic PSU, then it would probably be justified to spend $45 for this. Otherwise, you are better off sticking to your existing PSU until its end of life. (I ran some numbers. The savings on my annual energy bill would just be about $5. It would take 9 years to recoup the cost.)

It's Green...no literally this thing is finished in matte Green.
It doesn't come with a power cord
It also is 80 plus Bronze certified and runs very, very quiet.
There is an 80mm fan but the thing barely spins up...I wasn't sure if it was on or off a couple of times. The fan also pulls air from inside the case and exhausts it out the back. There is no rubber ring protecting the cables coming out the power supply from the power supply unit's case...only a zip tie.

The thing works, and for US$45 I am hard pressed to find anything better.

Tomshardware did a Sub-$75 Mainstream Power Supply Roundup and I can clearly see why this came out on top.

I was looking to fix a "E-machine Model W3644" computer with a blown power supply for a customer and it needed a ATX ("A"dvanced "T"echnology e"X"tended) sized replacement that didn't need such a high wattage. The 380 watts on this seemed an excellent range to purchase and install. It was well packaged when it arrived. It has a cool green color.

* Keep in mind it has no power supply cord. Use your old one if possible or buy one before purchase. *

It has various connectors such as:

1 x 20+4 Pin ATX Connector
1 x 4+4 Pin ATX 12V Connector
1 x 6 Pin PCI-E Graphics Connector
5 x SATA Connectors
4 x Molex Connectors
1 x Floppy Connector

For the price this is the best power supply you can buy for a system that doesn't demand too much wattage power.

I would recommend this product. It has connectors for various peripherals. It is 80 PLUS certified (which means: it promotes energy efficiency. It certifies products that have more than 80% energy efficiency at 20%, 50% and 100% of rated load, and a power factor of 0.9 or greater at 100% load. That is, PSUs that waste 20% or less electric energy as heat at the specified load levels, thus reducing electricity use and bills compared to less efficient PSUs.)

It also has a Active PFC up to 99%. PFC means "Power Factor Correction" which allows power distribution to operate at its maximum efficiency. There are two types of PFC, Active PFC and Passive PFC. The preferable type of PFC is Active Power Factor Correction (Active PFC) since it provides more efficient power frequency. Because Active PFC uses a circuit to correct power factor, Active PFC is able to generate a theoretical power factor of over 95%, hence this power supply can go up to 99%!

This is probably the best available power supply for small systems.

You should realize that most power supplies are WAY over-powered for common needs. It is truly a case of more is less. Let me explain: power supplies run their most efficient at 50% of their total rating. It is at the 50% mark that the efficiency ratings are based (80 plus, bronze, etc).

I strongly recommend getting a killawatt to determine how much system power you will need to function, then base a power supply selection on that. In my case, my HTPC (i3-3225 on an asrock z77 pro4m, 16gb RAM, 120gb SSD and 1tb HDD) was only consuming 48Watts at max usage. If I'm only running 50W (as I confirmed with my Kill-a-watt), technically I should get a power supply sized at 100W. But there really isn't a power supply that small! The popular Antec EA-380D Green at 380W, (tiny by market standards), is still overkill for my system. It may even be running outside the specs that qualify it for its 80 Plus Bronze certification! But it's the closest thing I can find.

Other pros: the fan is very quiet.

Very happy with this! 5 stars

Update 1/1/2014:
Still going strong almost 1 year into using. I've generously upgraded the storage of my system, I still find plenty of expansion room in my power needs. Would absolutely buy again.

Update 7/1/2014
I recently added a UPS backup to the system. One of the great features about a small power supply such as this is the capability to use a non true sine-wave UPS. Usually for active PFC power supplies such as this one, a pure sine wave is required(which can be very expensive). However given the low power rating, 380, you can get away with an approximated sine wave. I am currently using an APC Back-UPS 550 (BE550G), which I can confirm is compatible with the EA-380D.
