Athena Power AP-RRP4ATX6508 80 PLUS Certified 20+4Pin 2 x 500W Mini Redundant Server Power Supply - OEM

Pros: This has been running now for nearly 1 year straight (it was off for a day or two during the year is all) It appears both modules are working great as we haven't had a single power issue during this time.

Cons: The fans are a bit loud, but can deal with it.

Pros: -Very heavy unit, seems well built.

-All internal components visible from the outside look to be hi-quality(no off-brand caps, etc).

-Perfectly stable under load, barely even a flinch when tested spinning up (5) 15k600 sas drives non-staggered(normally I enable staggered spin-up regardless)

-Runs cool, the 80plus rating shows here, my older SM redundant psu's run much hotter even with very little load.

Cons: None so far, as long as it keeps the server running it's perfect as far as I am concerned.

Other Thoughts: It sounds like it belongs in a server room(hi-speed fans). Something to keep in mind depending on where you are going to place this.

Pros: -80+ unit for this price
-Active PFC
-Solid construction (it's very heavy, no bulging caps)
-Output tested within specifications
-Tolerates single module failure with no voltage drop
-Great service (see other thoughts)

Cons: -Difficult to mount in some chassis (put this in first)
-Does not come with documentation
-Runs a bit too loud for anything but the server room

Other Thoughts: Overall I'm very impressed with this unit. Output tested almost dead on with the supplied specs. The packaging didn't come with a manual, but I contacted Athena support and they were happy to provide me with relevant (if a little sparse) documentation. I did have a module fail on me, but the server continued to run fine on just one module. I sent an email to Athena and they called me within 15 minutes, agreed to cross ship the module (shipped out the same day!), and updated my account to allow for one more module RMA within the 3 year warranty period. I've had units from Supermicro and others fail as well, but never received anything like decent support. This is just something that happens with power supplies (otherwise why would anyone purchase a redundant supply in the first place). The features for the price and outstanding customer service are what set this unit apart. I was so impressed that I'm now planning to deploy several more of these for a new virtualization project.

Pros: Fits ATX case. Easy to install.

Cons: 1 of 2 power supplies DOA. I have sent at least 5 RMA requests in the last month and Athena will not respond. I have called them and waited on hold for over an hour and no one will answer. Worst support I have ever encountered.

Manufacturer Response:

We at Athena Power apologize for the inconvenience, I have checked the documents and all past RMA request and e-mails regarding an RMA request for the AP-RRP4ATX6508 model and there has been no cases for it whatsoever. Please immediately contact us at (626) 810-5008 ext. 102 or e-mail us at service@athenapower.us, I will have all service representatives look out for your case so we can assist you immediately. Thank you.

Pros: Works perfect, voltages are constant. Alarm is testable. This thing is HEAVY!

Cons: Its so great that i HAVE to put them in every server i build.

Other Thoughts: NEVER listen to a review from someone that would give any product 1 egg. Remember, incompetence is not an option on tech knowledge, but 1 egg is!

Pros: I am very lucky that I found the first 80+ certified redundant power supply here. It is a great, heavy duty power supply which is swappable.
It has 3x +12v and 2x EPS 8-pin outputs which support my Intel core i7 motherboard.
It also has 2x 6-pin PCI connectors which support my G-force VGA card, and a lot of SATA connectors that can use for my SATA hard drives. This master piece saves me money comparing with the one I had previously.

Cons: When I am running it, it has loud noise; but I can accept it. I need a screwdriver to take out the module, which takes time, but more secured.

Other Thoughts: Good Promotion! very good deal with $30 bucks discount and free shipping
