This is a great PS (power supply) unit. Not only is it very quiet (good for me), my PF is around 98% (good for the power company), and the 80 plus rating ensures that it is significantly more efficient than my older PS units (good for the environment as most of my electricity is produced by somewhat-less-than-green sources). While this is my first Earthwatts series unit, I do own mulitple Antec units and have never experienced a failure.

I needed a new PSU after upgrading my video card to an 8800 GS and only having a 380 W PSU. I found this Antec EA650 for a good price on Amazon via DataVision Computer Video. It does what it advertises and it should prove to be able to handle upgrades for a long time as it offers lots of Watts on the three 12 Volt rails (22A, 22A & 25A). [...]

This is my second Antec PSU and they have run quite well for me.

I purchased this unit to power a HIS HD 4670 iSilence4 Native HDMI 1GB (128bit) 850 MHz DDR3 PCIe in an Asus CG5720. Though it was the first of two components I have ever installed into a PC, it was a snap. Keep you old supply connected but remove it from the housing. Then mount the Antec. Unplug one connection at a time from your old supply then plug it into the appropriate connection on the Antec. It was a breeze. This thing runs quietly and hasn't had any glitches since.

Caution - be sure your UPS is of the pure sign wave variety, or it'll likely not work with the green Antec power supplies. The UPS's won't switch over fast enough and the computer will reboot. Power supply does not work with my APC BR1000G - APC told me to get the SmartUPS for $450 instead! Different power supply will be much cheaper.

Nice power supply but for a small case you may
have problems with all the cables because they are
not (modular) removable.

When purchasing my latest PC from Dell a year ago I opted to upgrade many of the features including the RAM, CPU and Graphics card. What I failed to take into account and wasn't alerted to by Dell, was that the PSU could barely take these upgrades. So when researching new additions to my PC I realized I would need a significant upgrade over the 300 Watts I had.

After reading multiple reviews I chose the Antec EarthWatts 650w as it clearly met my needs and budget. The item was easy generally easy to install, although the amount of cables left little spare room inside my case (which isn't particularly small). It is clearly a quality product as it felt significantly heavier and sturdier than the PSU I replaced.

So far the PSU has done everything I have asked of it without any hesitation, including graphics, video editing and gaming (Empire: Total War & Fallout 3: Game of The Year Edition). It is quiet, powerful and eco friendly. Short of having a huge gaming rig this will be more than enough for the average user, just don't buy it if you have a minuscule case.

Powers an HD 5770 without struggle. Solid construction and quality.
Cons: Not modular (your case might get a bit messy with all the connectors this PSU sports).

The Earthwatts 650 is a solid power supply. Easy to install, though you should know what you are doing. The manual in the box is really not much help if you haven't worked inside your computer before. There are a lot of cables with this power supply so careful arrangement is necessary to avoid obstructing airflow. I consider it reasonably quiet when running, I don't really notice it.

It supplies plenty of power for a typical home computer. I upgraded from a 300 watt power supply to have ample power for a newer video card. Antech has a good reputation. The power supply is heavy which strangely enough is something of an indicator of quality when it comes to power supplies. I have been monitoring voltages supplied by the power supply and they are well within spec and stable.

I am very happy with the Antech Earthwatts 650.

The unit runs very quiet and installation was simple (if you know how to install one PSU, you know how to install all of them) but I've had many power related issues with my system. It turns out the power supply has failed and needs to be replaced. Antec requires you to pay for shipping to them and they'll send a unit out to you. Their customer service was slow to respond to many issues and have forced me to purchase an alternative PSU. I would look elsewhere if you are looking for a quality PSU that's supported well.

No problems for the first two weeks that I have owned it. Since it's not modular, I decided to wrap the extra cables around the far side of the disk drives and stuff them in between the hard drives and the front of the case. Now they are out of the middle of the case.
