5 out of 5 eggsVery Nice PSU

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: Better cables and hardware then what i expected. Looks and feels solid. Boxed up very nicely just like the the Corsair HX750 that I also got.

Comes with a nice bag to keep extra cables and all the hardware you need to set it up with extra screws, zip cords, and a set of thumb screws for the PSU if u don't want to use regular screws.

Pretty much had all the same things that the Corsair HX750 that also bought came with. And one that the Corsair did not come with that is a set of really nice thumb screws.

Great warranty 7 years.

Price over Corsair.

Has really good reviews on line.

Cons: Nothing right now.

Other Thoughts: Will buy this type PSU again can't see now paying extra money for Corsair PSU moreover now that Corsair customer service sucks so much and they make jump over hoops to even get a Case manual that ur case is suppose to come with already.

1 out of 5 eggshorrible

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: This is a very well-built power supply. The casing is solid, the connectors clicked in solidly, the 24-pin fit without too much pressure, and the options for connectors was smart. The voltages were very stable under heavy load and I was able to overclock my FSB much higher due to the stable voltages.

Unfortunately, all this is completely irrelevant (see cons)

Cons: It failed on day two! My kill-a-watt meter reported that I was only drawing about 250-280W at the wall so there is no excuse for this to have completed failed in that time. I tried testing it with a paperclip on the green to ground and the fan wouldn't spin. It just clicks unhappily. I tried it with a new power cord, on a different circuit, and in a different building. Nope, it's dead.

In 7 years and building about 400 computers I've had a power supply fail this quickly once and it certainly wasn't a gold certified, award winning one. Avoid this power supply at all costs. There is either a severe design defect or they're lying about the build quality and specs.

Other Thoughts: The shipping box wasn't damaged, it didn't get wet, I didn't have a power surge or outage, and I barely got about 15 hours on the power supply before it failed. There is simply no excuse for that early of a failure.

5 out of 5 eggsRosewill CAPSTONE-450-M 450W Modular PSU

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: 1) Small footprint inside my Mid tower case. Semi Modular version works well for the room I had. All connectors were fine and proper.

2) Works like a charm, can't hear it running ( I checked just to make sure it WAS running right, lol)

3) Plenty enough power for my A-10 7850k system running 4.2.

4) Truth: Was going to go with a Corsair model....BUT, after mulling it over I decided to give Rosewill a try and save a few bucks in the process. So far, so good.

5) Daddy's happy and that's what counts! :)

Cons: None

1 out of 5 eggsCapacitor(?) Blew After a Few Hours

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: It's Modular and it looks nice.

Cons: After taking all day to build a new PC I turned it on and it ran for hours, then out of nowhere there was a loud cracking sound and everything shut off. Now it refuses to power on.

It's REALLY big, it barely fit in my Mini-ATX.

Other Thoughts: I just RMA'd, 10$ to ship it back and delay the build, which was a gift.

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!

5 out of 5 eggs

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.
