5 out of 5 eggsBuilt like a Fortress

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

Pros: I've been running this in a Core I5, GTX 660 Ti system for over a year and this power supply has impressed me. First of all, great energy efficiency! My system doesn't even reach 300W on full load. 80W average on idle. Of course your mileage will vary. Quiet operation; I don't even know what this PSU sounds like, all I hear are my case fans, CPU cooler, and GPU. I bought two at the same time, one for my system, and another for my little brother who games all day, literally. I built him a low-power ITX gaming PC and this PSU has more than enough power for it. This PSU helped cut down our electricity costs. Also, it looks cool through my case window.

Cons: Doesn't come in white.

Other Thoughts: It's not modular, but I use just about every connector so that's okay with me.

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

Pros: This power supply is very honest in its rating. Bought this on a whim for a new build, wound up using it for a bitcoin power supply. One of the few that surpassed my expectations.

Cons: none

Pros: Does as advertised.
I was a little weary of the Rosewill brand, but I'm now convinced this is a quality product after nearly a year without any issues.

Cons: None. I'm a satisfied customer.

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

Pros: Works exactly like it should.
Plugged it in, turned computer on, and it instantly recognized my flash drive.

Cons: None with the product.

Other Thoughts: Took a while (about 7 days) to ship with the free shipping. Did come from China though, so understandable.

5 out of 5 eggsSo awesome, I bought another one a year later

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

Pros: Incredible 7 year warranty (unlike most other Rosewill models that INCORRECTLY listed 7 yrs instead of 5 yrs on the NewEgg ads last month....what is WITH that, NE?), ridiculously competitive pricing every November on sale in the 550W size, Great non-NewEgg reviews. Although I haven't done the fancier review tests, professionals did and were pleased.

Cons: Unfortunately, some sloppy quality control: loose AC power plug (see my review and following correction last year about this time on this model) may toast your unit the first time you turn it on (easy to avoid). Last year's unit continues to work flawlessly. New one came with 1 loose screw rattling around inside unit and a second screw almost completely unscrewed. These are of the 4 screws that hold the circuit board down! Shook out loose screw, managed to tighten other one. was able to do this without voiding warranty by loosening fan screws and placing screwdriver between the fan blades. Unit is working great so far. Just pay attention to details before you power this on the first time (otherwise prepare for fireworks!), and this is a great value. Great sale price only once a year so far, and only on this wattage. Other wattages have had much less impressive "sale prices". For example, this November best sale price on 450W model was $8 more and that's not including the $20 Rebate Card offer I didn't submit on the 550W! So $28 more for 450W over 550W - go figure!

Other Thoughts: This model and size is the cheapest top-tier quality PSU on the market when at its best sale price. I paid so little for this Platinum that most equivalent quality on-sale Bronzes are pricier, so if you can wait for another sale, calculating electricity saved for Platinum is unnecessary. You just win.

5 out of 5 eggsWorking well so far

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

Pros: 80+ Platinum, plenty of connections. Long warranty. Been using for about 11 months now in a custom build with no problems.

Cons: None

Other Thoughts: Using it to run a quad core Ivybridge, 4 HDDs, 2 SSDs, 1 GTX 650 Ti, 1 DVD drive, 2 x 8GB RAM, and a 16 in 1 bluetooth card reader with no power problems.

5 out of 5 eggsGreat PSU, one small quirk

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

Pros: A lot of power for the money. 7 year warranty backs it up. I don't normally associate Rosewill with PSU quality, but maybe I will now.

Cons: Not modular, yada yada yada. For some strange reason the other half of my 8 pin mobo power connector doesn't match up to the connector on my MSI Z87-G43. One half fits (4 pins) and that seems to be enough to power and run my system without problems. I was expecting that the other 4 pin would match up and fit. Very odd.

5 out of 5 eggsHighly recommended, high quality Rosewill!

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

Pros: -EXTREMELY Quiet..I used this psu to replace a cheap noisy chinese branded 800W Psu..what a night and day difference!
-The casing on this psu is the best I have ever seen..the lizard skin-like texture really makes this psu come alive in my windowed case
-Went from pulling 180 watts idle to around 95 watts idle (though I did switch over from a amd phenom 955 to a 4670k)
-This psu has very very long cables, long enough to reach all parts of my Silverstone RV02-E case (which is the longest case ever really)
-Built solidly. this thing feels like a tank compared to my old psu.

Cons: not modular, but i dont need modular cables

Other Thoughts: this PSU is powering :
I5 4670k Overclocked to 4.6 ghz @ 1.25 V
team vulcan 2x4gb ram 1600 mhz ddr2
gtx 580 1.5gb

5 out of 5 eggsWorks great

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

Pros: 7 Year Warranty. Quiet. Runs cool. Plenty of connectors. Wires are nice n beefy. Comes with nice little touches like a velcro wrapper for your wires and some zip ties if you need it. Power output is nice n stable.

Cons: None, it runs great.

Other Thoughts: Some people complain about at this price it should be modular. But I would rather have the extra few dollars go towards the PSU itself rather than a bunch of connectors.
