5 out of 5 eggsPlenty of Power for Home Builds

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

Pros: First time I have ever used a Rosewill power supply but with the feedback here plus 80 Plus Gold certification and the significant drop in price I was sold for a new home office build I was putting together for my parents.

It is perfect in a HAF 912 case.

1) Modular Cables
2) Well packaged.
3) More than enough power.
4) Solid manufacturing

Cons: Cannot think of one except the possibility of needing an additional SATA cable.

Other Thoughts: I will definitely use this power supply for future home builds.

5 out of 5 eggsDecent power supply

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

Pros: Fit well in a Corsair 200R case. Cables were adequate length. Modular and 80 Plus Gold. Voltages look good. Came with plenty of zip ties for cable management.

Cons: None so far.

Other Thoughts: Take into account the fan guard sits just a little bit taller than the rest of the PSU. It still fit into the case, but required a tad bit of force since the fan guard was partially in the way.

5 out of 5 eggsSilent with more power than I will need for a while

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

Pros: Having owned a few other Rosewill products, I know that they are well built and thend to last, so I had no problem choosing Rosewill for my new power supply. No flashy LED fans here. It just quietly feeds juice to my components. It's fan is probably the most quiet fan in my case. Love that it is modular so I only have to attach the cables that I need to cut down on clutter.

Cons: None

Other Thoughts: Quiet with plenty of power. No drawbacks or negatives.

5 out of 5 eggsI'm happy

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

Pros: Works, gold rated, got it on sale, fan works well

Cons: Only time will tell

Other Thoughts: I haven't owned this power source long enough to say anything about its durability. It is however very stable for my system. I don't know how it would do with overclocking.

1 out of 5 eggsRosewill 550 w PS

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

Pros: Pretty cables.

Cons: Power Supply is keyed for PCI-E power connectors but they are not PCI-E Keyed connectors. One of the pins is 5v vice 12 volts and the swap is made in the cabling, so if you connect a standard PCI-e cable to the PS, one pin will be undervoltage. Also, since the cable connectors are keyed to the PCI-E standard (which has no 5v), and you connect the Rosewill PS cable to a standard PCI-e slot, 12 volts will be provided to the SATA connector 5 volt pin.

Other Thoughts: Using non IEEE standard cable Keys on the PS can cause hardware failures....that's why there are IEEE standards for PCI-e and cable KEYS.

5 out of 5 eggsVery Happy!

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

Pros: First time builder.
1.) Very well packaged
2.) High attention to detail in all components
3.) Great fit in Fractal Design R4 case
4.) Quiet as it gets (I'm also not running it hard)
5.) Cables were well made, zip ties a plus
6.) Modular cable inputs until the cows come home

Cons: An indicator LED would have been a useful addition.

Other Thoughts: Let's see how she holds up. Happy so far.

5 out of 5 eggsVery Quiet and Cool!

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

Pros: I have two of these. Both are very quiet and cool. Much more so than I originally thought. I have them in 2U rack mount cases with fan intake coming from the lid and not the interior. They add no heat to the case interior. Because the run cool, I expect low expenditure of energy with their use. I find that quiet to me means almost no audible level. QUIET!

Cons: None.

Other Thoughts: You should be happy with the efficiency of these PSU's.

Pros: Item arrived on time and was well packaged. I purchased this item for 63.00 before 15.00 MIR. All cables are conveniently marked and sleeved with durable material. As a whole, this item was a joy to work with while building.

Cons: None as of yet, will update if rebate doesn't arrive.

Other Thoughts: Would recommend.
