Antec EA-500 Green 500W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS BRONZE Certified Active PFC Power Supply - Intel Haswell Fully Compatible

Pros: 80 Plus Bronze! This was purchased for a pseudo-server that runs around the clock and I wanted to scrape a little from the electric bill. A platinum rated PSU would have been nice, but I couldn't beat the power/price ratio here. I've also read that the Earthwatts line concentrates its efficiency at different load levels than the 80 Plus certifications use for measurement, so this PSU is very likely more efficient than the Bronze certification gives it credit for. It's also SUPER SUPER quiet, which further qualifies it for round-the-clock server duty.

Cons: Two 12V rails? Perhaps this has something to do with the efficiency, but I find it a hassle. There are also only 2 PCIe connectors, so if you are planning to crossfire/SLI two or more video cards that each have two power connectors (as many high-end cards do) you will need some adapters. It's not modular. Consider the price and get clever with the tie wraps.

Overall Review: My little server doesn't have an externally powered video card (obviously), so 650 watts may be a bit much to power a PDC 5200, three 7200 RPM drives in RAID, a 5900 RPM "green" drive in the backup hotswap bay, and an OS SSD, but at least I know I will have enough power if I add disks to the RAID, replace the backup drive with something more power hungry, or replace the SSD with a platter drive (or some combination therein).

Pros: Nicely constructed and packaged. Works very stable and quiet. Plenty of connectors.

Cons: Low wattage.

Overall Review: Just wanted to update the review to state that the PSU is still going strong after years of use, and that I have since purchased another unit for a new build and it too is excellent.

Pros: Great Energy Efficiency! Silent Operation! Plenty of connections for builds of all sizes & purposes.

Cons: None - its great!

Overall Review: I've used this PSU in my own home server & numerous builds and have yet to have a single one die. It is great. Runs my newest system A4-4000 APU, 6GB Ram, Toshiba SSD, WD500GB Green Drive @ 22.5w idle. Wow.

Pros: Fills a niche missing in PSUs, which is a reliable low output PSU. Built well, as many connectors as it could need considering its low output.

Cons: NO POWER CORD!!! Says in the description, and most of the reviews, but it still caught me out, just shows you need to read very carefully. Also, the color is ugly, but this shouldn't be a concern if you're thinking of buying this.

Pros: Installed easily and works great.

Cons: The power supply fan is the loudest component in my build. Its not unbearable, but its audible.

Overall Review: I wish high quality vendors like Antec would make some lower power models. Many of the machines I build only need ~200-250W, but its hard to find reputable brands in that low power market segment.

Pros: High quality and inexpensive for low power systems.

Cons: Small fan, but isn't too loud

Pros: works and affordable.

Cons: antec did not do a very good job on this model when it comes to trimming/terminating the wires for the individual bundles. a lot of the wires are longer and i could not do a very good job of wire management.

Pros: High quality parts and price. Great PSU

Cons: Uses 80 mm Fans that can be noisy to some.

Overall Review: The rough green color was not to my fancy but I can get over it.. Good buy.
