5 out of 5 eggsPlenty of P-p-p-power

Pros: Completely Silent, even while working hard.
Nice modular cables.
Nice textured finish, with minimalist design.
Enough power for mid-high end systems.
Sweet rubber covers for unused modular ports.
Manufactured by SuperFlower.
5 year warranty.

Cons: None to speak of

Other Thoughts: This took the place of the same PSU, in the 650W flavor, for my media center; The 650 I moved to my desktop.

I wanted to test it's capabilities so I tossed my GTX670 4Gb in my media center which is composed of:
ASRock Z77-E ITX
i5 3570k @ 4.5 GHz cooled by Antec 620
8GB Ballistix 1600
120GB Crucial M4
2TB Barracuda LP
3 Arctic F12 PWM fans

Turned on Prime95 and Furmark with an extreme burn-in for an hour. This thing never flinched, and didn't make a peep either.

For someone with an Ivy CPU, a single high end GPU, and a couple SSD/HDD this is a worthy contender. The days of needing a 700+ watt PSU are fading away unless you are Xfire/SLI.

I wish more companies offered high efficiency PSU's in this wattage range.

4 out of 5 eggsUpdate

Pros: Quiet
Works well.

Cons: First one was bad.

Other Thoughts: I am back with an update. The first one I got from Newegg tested bad and I RMA'd it. The replacement arrived promptly and is now working without a hitch. It is very quiet and output is as spec'd.

I feel obligated to report the good and the bad with my reviews, and I have to say that this second unit is really a nice bit of kit.

1 out of 5 eggsDOA

Pros: None

Cons: Tests bad using Rosewill PSU tester

Other Thoughts: Not impressed with Rosewill products. I got an RMA and I will give them one more chance to make it good, and then no more Rosewill.
This is not the first bad product from them, but it is the last.

5 out of 5 eggs

Pros: After many PSU issues because of sub par and/or cheap units this one is still working great. Has all the proper connectors I needed and cable management was simple. Has been running 24/7 in a basic PC build that is mostly used as a "home server" for almost 3 months now.

Runs cool and I don't notice any fan noise.

Cons: None yet.

Other Thoughts: Very highly recommended/rated from other people I have talked to before I purchased.

5 out of 5 eggsGreat value!

Pros: Less expensive than Corsair 80 Plus Bronze equivalent, bigger fan and 5 yr warranty. Also is modular which is key to airflow and neatness.

Cons: None. Worked out of the box and not a single glitch.

4 out of 5 eggsso far so good

Pros: Gets good reccomendations from those who know. looks pretty good, semi-modular so you only use the cables that you need. great warranty

Cons: I still don't trust the Rosewell brand, but maybe this capstone psu will change my feeling that Rosewill is newegg's 'blue stripe' brand

Other Thoughts: I like it so far, works as intended, and does it quietly

5 out of 5 eggsExcellent bang for buck

Pros: Well constructed, reasonably quiet (but not silent), high efficiency, mostly modular. Based on a well-regarded SuperFlower platform. Given the frequent sales on this model, it's extremely hard, if not impossible, to beat the value of this model.

Cons: Length of ~170 mm. I was aware of this going in, but if you're replacing an existing PSU (which is quite possibly 140mm or perhaps shorter) or even if building from scratch, make sure you have room for it in your case.
