1 out of 5 eggsHad to return after 2 days

This review is from: CORSAIR CSM Series CS550M 550W ATX12V v2.4 and EPS 2.92 80 PLUS GOLD Certified Modular Active PFC Power Supply

Pros: none

Cons: The fans bearings failed 2 days after installing. Started to make a grinding noise. Others have had the same issue when I went searching online.

First experience with a corsair product. Not impressed with build quality on this line of psu.

4 out of 5 eggsHas been a great little PSU but a bit short life in my opinion

This review is from: CORSAIR CSM Series CS550M 550W ATX12V v2.4 and EPS 2.92 80 PLUS GOLD Certified Modular Active PFC Power Supply

Pros: -Easy to install
-price was great
-nice and quiet

Cons: -I wish the cables where a bit longer (personal preference - didn't knock off egg for this)
-could use more plugs on the sata power cables (personal preference - didn't knock off egg for this)
-Dying out in just over 2 years seems pretty quick to me. I am a pretty standard user and do not over use this psu with my requirements. Luckily its still under the manufacturers warranty of 3 years and I have submitted an RMA.

Other Thoughts: Depending on Corsairs response I may add that Egg back but until then 4 eggs is all I can give based on life of product before I had issues.

4 out of 5 eggsKinda Meh. Not Bad, Not Amazing.

This review is from: CORSAIR CSM Series CS550M 550W ATX12V v2.4 and EPS 2.92 80 PLUS GOLD Certified Modular Active PFC Power Supply

Pros: - Pretty good quality overall. Honestly I've had this going on a year, and it's been in a build for probably about 10 months. Over time I have added and upgraded parts and so far this hasn't failed to power them. Currently, it's powering my overclocked CPU, motherboard, 3 case fans, 1 (soon to be 2) CPU fan, an overclocked EVGA 970 FTW+ as well as 2 HDDs, an SSD, and an optical drive. Seems to be handling all of these parts with relative ease.

- Semi Modular! This is a big plus in my book. If a PSU isn't at least semi-modular, I probably won't buy it. This was my first build, so managing all the needed cables was to say the least, interesting. Adding in another 2 Molex cables that I really don't have a use for wouldn't have made that job any easier.

- Gold Efficiency rating. I suppose this doesn't have a large effect on how you use the computer everyday, or when you put it together, but I feel it's worth mentioning that this is more efficient that some PSUs, and therefore may be better for things like overclocking.

- It's efficient. The fan on the bottom doesn't come on unless it needs to, which due to the way I set my pc up, should be rarely, if at all. This is great, because fan being off = less moving parts = less noise in the pc, which is great, because the PC is probably less than 3 ft from my ears.

Cons: - The cabling. Honestly, the only thing I can really say is it sucks. The cables were far to rigid and stiff out of the box. Now, for some of those connectors, rigidity can't be easily removed. The 24 pin connector for example, it just has so many wires that there will be rigidity no matter what you do. However, when the GPU cables are so rigid that they don't easily bend when you put some pressure on them, it makes me frown a bit.

- The labels. Obviously the PSU has to have safety warns and such on the unit. But I would appreciate moving that to a side instead of the bottom. I have a windowed case, and I installed the PSU so that the top (the side with the fan) would be sucking in cool air through the bottom and exhausting it out the back, creating an airway totally separate from the rest of the case. This results in me seeing a giant blob of safety labels when I look in my case, and I really don't like that, as aesthetics are somewhat important to me.

- Connector Options. I've run out of SATA power connections. There are only 5 SATA power connections in this PSU, which sounds like a lot, ad if it were only for drives, then that would be more than enough. However, my case uses a SATA power connection for a built in fan controller. That only leaves the rest of my PC 4, one of which is taken up by my ODD, and 3 of which are taken up by my drives. I would've really liked to have seen another SATA power connector added, perhaps as either an adapter for the Molex cables, or replacing one of the molex connectors entirely. It's just a bit annoying, because should I ever want to add a CLC to cool my cpu, many of those use a SATA power connection to power the pump.

Other Thoughts: Over all, I'd recommend this to someone looking for a basic power supply, but I'd ask a couple questions first to make sure it's a system that they aren't really looking to upgrade much in the near future. When I originally got this, and was putting my PC together, I turned probably turned budgeting into an art form of some sort, just because I was working so much to get the maximum bang for my buck. Now that I have somewhat more cash, I can start upgrading, but I'm being limited by the PSU.

In short, if you just want something that works, and you don't foresee yourself upgrading things in the future, I'd say get this. It really is a decent PSU for the price. Most of my cons really aren't more than gripes that could easily be fixed. That being said, if you do foresee upgrading in the future, whether it be a month from now or a year from now, get a better PSU. It'll save you money in the long run because you won't be held back. I for one don't currently have the money to get a new PSU plus the rest of the parts I plan on eventually getting, so it's kinda coming back to bite me. Don't be me!

4 out of 5 eggsVery good

This review is from: CORSAIR CSM Series CS550M 550W ATX12V v2.4 and EPS 2.92 80 PLUS GOLD Certified Modular Active PFC Power Supply

Pros: This is reliable powerful power supply. run well with no hiss or hum. Modular. well put together.

Cons: cables attached to powersupply are too short. having it reach up in what is said to be a tight case didn't reach going behind the holes. it may be just because it is meant for smaller cases, but it is kind of a problem.

Other Thoughts: I like the powersupply. I feel it is reliable and won't be ripping you of your money.

3 out of 5 eggsNoisy fan.

This review is from: CORSAIR CSM Series CS550M 550W ATX12V v2.4 and EPS 2.92 80 PLUS GOLD Certified Modular Active PFC Power Supply

Pros: It's very silent when the fan is working.

Cons: I've had this product for about a week and a half and a couple of nights ago the fan started making vibrations and a clattering noise. I'm not sure if the fan is supposed to be running all the time but the sound comes and goes which leads me to think that its not.

Other Thoughts: This is powering my first build but I had people and friends reviewed and this was even a recommended product. I'm disappointed. 3 stars for a product that works when it's put together correctly but breaks in a small amount of time.
