5 out of 5 eggsThe Power and the Silence

This review is from: CORSAIR RM Series RM550 550W ATX12V v2.31 and EPS 2.92 80 PLUS GOLD Certified Full Modular Active PFC Corsair RM550 Power Supply

Pros: Upgraded to this from an OCZ StealthXStream 700W unit. That power supply had become about the loudest thing in my case, at least at idle. That's no longer an issue. The RM 550 doesn't even turn on its fan until you're over 40% load, so when my computer's on idle the PSU is completely silent. I think my case fans are now the loudest component in my system at idle.

Modular functionality is nice. I like having a nice clean case, and the fewer cables I need to leave lying around the better.

Also worth pointing out: Because of the passive cooling, this PSU is very likely to collect a lot less internal dust than other units. Maybe I just live in an exceptionally dusty environment, but keeping my components clean has been a constant struggle for me. It's nice to have something that will help in that regard.

Cons: As other reviewers have pointed out, the modular cables are a bit on the stiff side. I was still able to wrangle them around to make all of the necessary connections, but there was definitely some more force required than with my old unit. Also, some of the connections at the power supply are difficult to fully lock in, especially for the motherboard power strip. I had to work at it for a while until I was confident the cable was locked into place.

Other Thoughts: I recently moved my PC out to the living room after my wife got a desktop, and the old rig simply wasn't built with noise in mind. I've been working on upgrades over the last couple of months to quiet things down. I'd made a lot of progress, but this power unit has finally pushed things into a truly astonishing level of quiet. The system is barely audible on idle, and even at full load it's noticeably quieter than it used to be at idle.

The 550W model only comes with a single PCI-E cable (2 6+2 connectors), and with a single 12V rail this isn't going to be a solution for SLI/Crossfire or crazy overclocking. But if you're looking for a solid, quiet rig for a mid-to-high-end gaming system, I think you could do a lot worse.

My System Specs:
Fractal Design Define R4
Corsair RM 550
ASUS P7P55-M
Intel Core i5 750 OC'd to 3.36GHz
8 GB GSkill Ripjaws X DDR-1600
EVGA GTX 970 SC w/ ACX 2.0
Corsair MX100 512GB

5 out of 5 eggsRM550

This review is from: CORSAIR RM Series RM550 550W ATX12V v2.31 and EPS 2.92 80 PLUS GOLD Certified Full Modular Active PFC Corsair RM550 Power Supply

Pros: -Fully Modular
-Easy to install
Ever since I have installed this PSU and ran power through it, to now as I type this review, the fan has not turned on. This is not because it is broken, this is to limit the noise of your pc. The fan will start to run if it gets too hot and starts pulling a lot of power. Corsair was smart when thinking about a silent PSU. Why have a fan spinning if it is not needed? Hense this beautiful PSU was created.

Cons: Needs some force when connecting the 24-pin connector. Nothing much just could be a potentional of breaking something if you were to push to hard.

5 out of 5 eggsFully Modular, Silent PSU

This review is from: CORSAIR RM Series RM550 550W ATX12V v2.31 and EPS 2.92 80 PLUS GOLD Certified Full Modular Active PFC Corsair RM550 Power Supply

Pros: Quiet. Prime95 on my CPU didn't use enough juice for the fan to kick on. The fan only comes on when playing games and using GPU(about to get a 980 so it may not ever come on). And when the fan is on, I can't hear it at all. And I am in a fairly silent room.

Fully modular, every cable is modular including the motherboard and CPU cables. This makes it extremely easy to sleeve the cables on my own(I didn't care too much for the original flat black style)

Cons: Have to buy a separate $15 cable from corsair to plug this in to get corsair link. If you have the commander or another device that can read fan speed and a thermistor you don't need the special cable.

4 out of 5 eggsVery quiet, but very stiff cables

This review is from: CORSAIR RM Series RM550 550W ATX12V v2.31 and EPS 2.92 80 PLUS GOLD Certified Full Modular Active PFC Corsair RM550 Power Supply

Pros: The fan is extremely quiet, if not silent. You don't have to find a place to hide all the extra cables in your case.

Cons: The cables and connectors are stiff enough that you will fight with them both during insertion into the PSU and during any attempt at cable management during your build.

Other Thoughts: I've had this unit in my gaming rig for three months now. The fan seems to run all the time but I can't hear it over my GPU cooler.

If you have a case with a lot of hard drives or a lot of fans the fact that this PSU is modular probably won't matter since you'll end up using all the cables anyway, as I did. The cables were an absolute bear to route through the case but I have no doubt about how long they'll last.

5 out of 5 eggsGood NAS box PSU

This review is from: CORSAIR RM Series RM550 550W ATX12V v2.31 and EPS 2.92 80 PLUS GOLD Certified Full Modular Active PFC Corsair RM550 Power Supply

Pros: Silent, as is absolutely silent since running a home server with it doesn't stress the machine much. Running a Pentium with 4 HDDs and the fan only turned on once when my AC went out at home. No electrical whining noises like that either. It had plenty of cables for a 550w PSU, If you need more just get the next model up for $10 more.

Cons: None

Other Thoughts: I'm on the edge of whether I like cables with sleeves more than no sleeves (like this one). I think having the cables flat helps a bit with the cable management because they are less obstructive behind the motherboard.

5 out of 5 eggsSilent Fan Silent room~

This review is from: CORSAIR RM Series RM550 550W ATX12V v2.31 and EPS 2.92 80 PLUS GOLD Certified Full Modular Active PFC Corsair RM550 Power Supply

Pros: Since the fan is off when my power requirement is low....so there is no noise and the fan is off~

Cons: there should be like a led light make sure is the fan off because of low power load or it's defected...it's always worries me...

Other Thoughts: The power works perfectly after using 3 weeks...It's good....but the modular plugs r kinda bad and should redesign it...

5 out of 5 eggsGreat Value for the money

This review is from: CORSAIR RM Series RM550 550W ATX12V v2.31 and EPS 2.92 80 PLUS GOLD Certified Full Modular Active PFC Corsair RM550 Power Supply

Pros: Quiet as it says. Is not over hot. Actually, I feel mine is very moderately warm for the load. The modular cables are awesome. Really good supply.

Cons: None yet.

Other Thoughts: Buy a PSU that is a bit higher than your requirements. This way, it will run cooler at load. I think many have big computers that eat up lots of power and they expect the PSU to run cool. My 550 PSU is definitely more than my pure SSD server requires, but I have no problems with heat from the PSU.

1 out of 5 eggsNo longer works!

This review is from: CORSAIR RM Series RM550 550W ATX12V v2.31 and EPS 2.92 80 PLUS GOLD Certified Full Modular Active PFC Corsair RM550 Power Supply

Pros: For about a month that I've owned this PSU, my computer was working fine. I never saw the fan come on, so it seemed to be working at a comfortable level.

Cons: One day, the computer simply shut off and didn't turn back on. The motherboard wouldn't even light up. I replaced the motherboard and CPU thinking the problem came from them, only to find out that it was the PSU that crapped out. Clearly, this product is not very durable.

3 out of 5 eggsGreat power supply with a few issues

This review is from: CORSAIR RM Series RM550 550W ATX12V v2.31 and EPS 2.92 80 PLUS GOLD Certified Full Modular Active PFC Corsair RM550 Power Supply

Pros: - Efficient. Gold Certified is great.
- Quiet. I've never seen the fan turn on even though my system is relatively powerful (FX Processor and GTX 660).
- Good looking. The design is one of the better ones I've seen on a power supply. Like the white fan.
- High quality. HWMonitor is showing voltage variances of less than .05 on all rails.

Cons: - As other reviewers have said, the plugs on the power supply aren't very good. It takes a lot of effort to plug them in, and they don't click although they have a locking mechanism. (It's better to install the power supply first if you are building a new computer with this particular model.)
- The cords are a pain to route. The barely fit behind the motherboard in my Fractal Design Define R4 case. They aren't very flexible. Ordinary sleeved wires would have been better.

Other Thoughts: When I first powered up the computer with the new power supply (I had just changed the power supply from a TR2-650 to this), it shut down randomly about an hour in. However, it hasn't happened since then, so it's entirely possible it was still just being broken in. I've owned it for about 2 months now and it hasn't had any problems.

Also, I'm a bit worried about the fan. I have an FX 4170 processor, GTX 660, several hard drives and several fans. I thought for sure that this would put the power supply over 40%, activating the fan, but I haven't seen it turn on once. If it's broken, there's no way I could tell.
