5 out of 5 eggs

Pros: Works well and comes with plenty of cables for your power needs.

Cons: None!

Other Thoughts: Comes with it's own built in cables making it a non modular, keep this in mind.

1 out of 5 eggsUnreliable please purchase with caution

Pros: It's quiet and affordable...

Cons: I purchased this PSU on 3/3/2015 and received on 3/9/2015. It died today (on my birthday lol) after 1 month and a few days of use When I turned it on today the system rebooted itself and went to a black screen. I turned the computer off and was never able to turn it back on. I plugged in my 6 year old antec power supply that this one replaced and now my computer is working again. I would not recommend this product. I've worked in IT for a few years now and I have never seen a PSU die this quickly.

5 out of 5 eggsGreat Bang for the Buck

Pros: Great price on a good looking and well built power supply.

Cons: None.

Other Thoughts: I thought there would be something missing in the quality of this power supply given the price, but it seems solid all around. The finish looks nice and seems durable, the unit looks and feels well made, and the cables and ends are all nice.

1 out of 5 eggsNot stable enough for my NAS

Pros: Quiet, GOLD-rated.

Cons: Unstable 12V rail

Other Thoughts: I put this PSU into a FreeNAS box, based on the great reviews here at NewEgg. The PSU ran great for 3 weeks. Today, however, the system spontaneously rebooted. Upon checking the IPMI event logs, I discovered that the PSU voltages have been wavering for the past two days. As this unit is connected to a UPS device, I suspect the PSU is faulty. I will be returning it, and purchasing a better known brand name. You just can't take chances on a flaky PSU for a NAS system...

1 out of 5 eggsgood until it failed

Pros: 80 Plus Gold and 7 year warranty. Seemed like a good PSU while it worked.

Cons: Died in less than 18 months.

Other Thoughts: The PC had some anomalous behavior (including some BSODs) in the few months leading up to complete failure. I thought it was a hard disk or filesystem issue, but now that the PSU has failed, I know it was the PSU not providing the correct voltages. I've checked the pins and they all report zero volts (except for one). So how do I get this thing fixed under warranty? The Rosewill website isn't much help.

5 out of 5 eggsGreat for a normal PC

Pros: Very efficient and a good power rating for a mainstream PC.

Cons: It might be worth spending the $5 extra for the modular version.
