5 out of 5 eggsSuper Quiet!

This review is from: Rosewill CAPSTONE-550 550W Continuous @ 50°C, Intel Haswell Ready, 80 PLUS GOLD, ATX12V v2.31 & EPS12V v2.92, SLI/CrossFire Ready, Active PFC Power Supply

Pros: Got this because of the gold rating and low noise. This PSU is actually really quiet! I'm fully satisfied with it so far. It looks good... all black. Good long cables... reached everything with the PSU mounted on the bottom and cables hidden in the back of mobo.

Cons: None so far.

Other Thoughts: I don't have a graphics card yet to load up the PSU and see how loud it gets then.

1 out of 5 eggsDOA

This review is from: Rosewill CAPSTONE-550 550W Continuous @ 50°C, Intel Haswell Ready, 80 PLUS GOLD, ATX12V v2.31 & EPS12V v2.92, SLI/CrossFire Ready, Active PFC Power Supply

Pros: None

Cons: Part of a new build. Assembled new machine but it wouldn't post. Board power LED lit so I assumed power supply was working. Spent about an hour troubleshooting. Finally found a power supply tester and checked unit. No 12v output at all.

Other Thoughts: I understand when electronics sometimes fail early on (one reason for a burn in right?) but when something is bad out of the box that seems inexcusable. Really annoyed about all the hassle that I am going to have to go through now.

Seems like a fair amount of failures in the reviews so I would say skip this one and look elsewhere.

1 out of 5 eggsFailed After One Year Of Use

This review is from: Rosewill CAPSTONE-550 550W Continuous @ 50°C, Intel Haswell Ready, 80 PLUS GOLD, ATX12V v2.31 & EPS12V v2.92, SLI/CrossFire Ready, Active PFC Power Supply

Pros: Powered all of my system components for about a year.

Cons: Unit started failing today. Power cut twice within 30 minutes while gaming. No other devices on power strip affected. All other devices plugged into power strip retained power.

Other Thoughts: For a 'gold' standard unit (whatever that means), this is very disappointing. Will not purchase another Rosewill PSU.

1 out of 5 eggsCan't maintain power

This review is from: Rosewill CAPSTONE-550 550W Continuous @ 50°C, Intel Haswell Ready, 80 PLUS GOLD, ATX12V v2.31 & EPS12V v2.92, SLI/CrossFire Ready, Active PFC Power Supply

Pros: Worked well for about a year

Cons: Last Friday, my computer suddenly died. It kept attempting to power back on, but would turn off after a few seconds. After 3 of these cycles I unplugged my computer to try and avoid damage. I tried starting my computer again the next day and it started for 5 minutes, and started the death cycle again.

Other Thoughts: I'm definitely going to get the 2 year extended warranty on my next power supply. Also going for a modular, all of the extra cables were a pain in my mid size tower.

1 out of 5 eggsDead within 2 months

This review is from: Rosewill CAPSTONE-550 550W Continuous @ 50°C, Intel Haswell Ready, 80 PLUS GOLD, ATX12V v2.31 & EPS12V v2.92, SLI/CrossFire Ready, Active PFC Power Supply

Pros: Good buy for the wattage and 80 Plus Gold PSU.

Cons: Just died this morning (Jan 6th) after having it in a build for less than 2 months. Even worse this is a PC i built for my parents who are 5 hours away. PC is just running an i7 and gtx 650 - both factory clocks - nothing that could've strained a decent 550W supply.

Had the best reviews/price point for the wattage I was looking for so I picked this one out hoping for something I could "set and forget" for them. Now I get to scramble to figure out how to get them back and running ASAP.

Other Thoughts: First power supply I bought from Rosewill and the only PSU I've ever had fail on me (even worse not me - but a PC built for someone else). Always stuck with Corsair for my gaming builds and will for all other builds from now on. even if I pay a premium.
