1 out of 5 eggsLacking Quality - Failed in Less than a Year

This review is from: Rosewill CAPSTONE-450-M 450W Continuous @ 50°C, Intel Haswell Ready, 80 PLUS GOLD, ATX12V v2.31 & EPS12V v2.92, SLI/CrossFire Ready, Modular Active PFC Power Supply

Pros: Quiet
80 PLUS Gold
Cool
Modular
Many accessories
7 Year Warranty

Cons: Failed in less than a year. Had to RMA. Shipping is expensive and slow. PSUs shouldn't fail in less than a year for quality PSUs. Failed paper clip test (fan would spin for a second, then stop)
Large
Heavy
Really long cables if installed in a small case

5 out of 5 eggsVery silent

This review is from: Rosewill CAPSTONE-450-M 450W Continuous @ 50°C, Intel Haswell Ready, 80 PLUS GOLD, ATX12V v2.31 & EPS12V v2.92, SLI/CrossFire Ready, Modular Active PFC Power Supply

Pros: * Very good price
* Modular
* Very silent, I don't hear it 2.5 feet away. If I put my hear very close to the case, I will hear a very light sound due to the air blowing. Is it the CPU fan or the PSU fan (or both !), it is hard to say. Compared to a Corsair CX430 I had previously, I can say that this PSU is more silent. I know that another customer has another point of view. Maybe it is because his system needs more load ? My system runs at about 35% load.

Cons: I wish the cable with 4 SATA plugs would be one inch longer. I cannot use only one cable to reach the SSD at the bottom of the case and then the HDD (in the middle area of the case) and then the DVD burner (case top area) ; with a micro-ATX case. But, maybe, it is better to spread the devices on 2 cables anyway ?
It is more a suggestion for improvement than really a cons.

3 out of 5 eggsperhiperials are stuck! Noisy!

This review is from: Rosewill CAPSTONE-450-M 450W Continuous @ 50°C, Intel Haswell Ready, 80 PLUS GOLD, ATX12V v2.31 & EPS12V v2.92, SLI/CrossFire Ready, Modular Active PFC Power Supply

Pros: -Inexpensive
-80 Plus Gold

Cons: -the plugs fit extremely tight into all of my peripherals. My DVD and SSD plugs are permanently stuck!!!!! I tried using tools to get it out. Impossible.

-Molex connectors were all crooked. Difficult to plug in...

-Same noise level as my previous 350 Watt Sparkle PSU made in 2004

Other Thoughts: -Inexpensive, 80 plus Gold. Just make sure you plug it into the peripherals right the first time. Most likely they will not come out.

1 out of 5 eggsAVOID AT ALL COSTS

This review is from: Rosewill CAPSTONE-450-M 450W Continuous @ 50°C, Intel Haswell Ready, 80 PLUS GOLD, ATX12V v2.31 & EPS12V v2.92, SLI/CrossFire Ready, Modular Active PFC Power Supply

Pros: Seemed like a good price for an 80+ gold psu....

Cons: Died after about two months of normal usage on a E3-1230v2 Xeon workstation. Something made a loud noise (capacitor failure?) while the system was running, screens went blank and both a discrete sound card and my video card where dead after it abruptly shut down (voltage spike on pci-e rail?). The PSU was plugged into a high quality surge suppressor, so external current supply and /or ripple was not a casuative factor.

Other Thoughts: Felt light and rather cheap in comparison to even a foreign made Seasonic. Just avoid the temptation on these models - cheap can get awfully expensive when it takes a dump on you and takes other compenents with it!

This review is from: Rosewill CAPSTONE-450-M 450W Continuous @ 50°C, Intel Haswell Ready, 80 PLUS GOLD, ATX12V v2.31 & EPS12V v2.92, SLI/CrossFire Ready, Modular Active PFC Power Supply

Pros: More than enough headroom for most people. Probably not enough for a dual GPU system, but otherwise it's plenty.
Great reviews online for this model. It has high-end components and meets or exceeds its Gold rating in said reviews.
Good value (I got mine on sale for fity dollars)
Modular means you only use as many cables as you need and pack away the rest. Less case clutter.

Cons: None!

Other Thoughts: It is physically larger than any other PSU I've ever seen. Rather than being square in shape, it is slightly deeper than it is wide. No concern for me, I just thought I'd mention it.

3 out of 5 eggsNightmare

This review is from: Rosewill CAPSTONE-450-M 450W Continuous @ 50°C, Intel Haswell Ready, 80 PLUS GOLD, ATX12V v2.31 & EPS12V v2.92, SLI/CrossFire Ready, Modular Active PFC Power Supply

Pros: System powered on. Wakes from Haswell deep sleep.

Cons: Too noisy! 2X noise than 2 year old inexpensive Cosair CX-430. Extremely unhappy. I put the Corsair back in. Going to have to go fanless not to have diesel truck noise in my studio. It may not be defective. Maybe normal. Product reviews have quiet 93 times in 161 reviews. Either these customers have ruined their ears listening to rock music or I got a bad one.

This review is from: Rosewill CAPSTONE-450-M 450W Continuous @ 50°C, Intel Haswell Ready, 80 PLUS GOLD, ATX12V v2.31 & EPS12V v2.92, SLI/CrossFire Ready, Modular Active PFC Power Supply

Pros: Nicely made, modular, worked right out of the box.

Crinkle finish flat black paint job is attractive and professional looking.

Cool and quiet operation. Voltages are spot-on.

Cons: None worth mentioning.

Other Thoughts: Installed a couple of days ago, so reliability is yet to be determined.

3 out of 5 eggsOverall good PS

This review is from: Rosewill CAPSTONE-450-M 450W Continuous @ 50°C, Intel Haswell Ready, 80 PLUS GOLD, ATX12V v2.31 & EPS12V v2.92, SLI/CrossFire Ready, Modular Active PFC Power Supply

Pros: Modular, Great Price, 80 Plus Gold, large fan making this very quiet, almost silent in operation.

Cons: Size. Should have realized the large fan makes this huge for a 450 watt PS. Same physical size as the 800 watt!
None of the Power plugs are right angle, and one of the SATA plugs was defective.

Other Thoughts: Replaced the PS in a Gateway i5 and this barely fit because of the length. What was surprising was that Gateway required right-angled SATA connectors for the HD, and this has none. Had to use one from the old PS and crimp it on this one. Had to use a third cable just to feed the DVD drive because one connector was defective. One star off for each.
