CORSAIR RMx Series RM650x 2018 CP-9020178-NA 650W ATX12V / EPS12V 80 PLUS GOLD Certified Full Modular Power Supply

Pros: This is the perfect PSU for a mid tower build. Small in size, but sturdy in its weight. Fully modular. I love minimalist builds that are clean. You can't get that without fully modular cabling. 80 plus certified. This is very solid efficiency and will save you money on your electric bill over the lifetime of the PSU. I love the cabling. They're stiff, similar to EVGA and SilverStone. But not so stiff to not be route-able and manageable.

Cons: The only reason I'm not giving this 5 eggs is due to the length of the CPU power cable. There are a tons of great cases out there in the mid and full size that have bottom mount PSU housings. This PSU will not reach the CPU power, or ATX for that matter, connector in a full size case.

Overall Review: I have been running a Ryzen 1700x, 1080ti, 16GB DDR3, 3 SSD's, 3 7200 RPM HDD's for storage, and my disk drive and even under full load the PSU is silent and I've had no issues with gaming. If you've come to Newegg, you already know you're looking for a solid PSU at your price point. But don't ever "cheap" out of a PSU. You get what you pay for. The PSU, while not as flashy as that GPU, CPU, or RAM, is the most important piece for any build. Especially longevity. Do your research and get the best PSU in your price point. 650W is more than enough for today's modern CPU's and GPU's. Please go check out reviews for the 850w version and a specific indepth review of the 650w version. These reviews take a deep dive into the components of the PSU, performance testing, thermal testing, and load testing of the PSU. A PSU is all about longevity and stability. Corsair is one of the leaders in the market. Their longevity and history in the market space speaks to the reliability of their products.

Pros: The Corsair RM650x 2018 [V2] is the update to their RM line featuring 80+ gold level efficiency. It is produced by long term OEM partner channel well [CWT] It is fully modular, main cables are very solid construction wise and it features Corsair standard flat ribbon SATA cables which are stiff but can be made more pliable with hot air. The mild update includes a bypass relay which supports the NTC thermistor, allowing for increased efficiency and enhanced inrush current protection. Also included is a PIC micro-controller to control the fan's operation and allow it to run at lower RPM's further cutting noise. All caps, primary and secondary are Japanese made by Nichicon and Nippon Chemi-con. The fan is a 135MM rifle bearing, good but could be better with FDB. The fan curve, it does not turn on until roughly 250 watts and remains flat at roughly 600 RPM until 600 watts are being drawn. Designed to be bottom mounted I can't see the temperatures even without any airflow of being any concern. Just note it's not temperature controlled but watt draw controlled. If your system rarely sees power output up to 250 watts not only will you have zero noise but I'd suspect the fan will easily last the 10 year warranty. Fit and finish is very nice in standard matte black, beige accent around the model logo. 10 year warranty and Corsair does a good job with RMA's if you needed to. Intel C6/C7 Power State Support Ripple is extremely low and voltage regulation is one of the better currently on the market. Cables included: 1 x ATX CABLE 24-PIN (20+4) 1 x EPS/ATX12V CABLE 8-PIN (4+4) 4 x PCIe CABLE 8-PIN (6+2) 9 x SATA CABLE (3 SATA) 4 x PERIPHERAL CABLE (4-PIN) 1 x FLOPPY DRIVE ADAPTER (4-PIN) Speaking of cables, to further line regulation the ATX, EPS and PCIe cables have caps under the shrink wrap, this adds some extra thickness which depending on your case might make for tighter fit through openings. Voltage is flat, using a digital volt meter at the max watts my setup can output [236 watts] I get: 12.19V 5.02V 3.20V Protections: Over Voltage Protection Under Voltage Protection Over Power Protection Over Temperature Protection Short Circuit Protection Surge Protection Inrush Current Protection

Cons: No fan test button, if your system does not draw up the threshold you won't know if you have a faulty fan. I was able to by adding some external DC fans get the PSU fan to kick on briefly enough to physically see it working and it was dead silent so I am satisfied. This is certainly not a deal breaker.

Overall Review: Price is competitive for the gold rating, power output and features. Included velvet bag is overkill but nice and can be used to store something. Included nylon pouch with velcro as Corsair has been doing for many years is handy for holding extra cables not being used. Once you setup your system most likely you won't visit this pouch often. I have a junk drawer with a couple of these pouches just in case. Overall the V2 of the RM line has great fit and finish, excellent regulation, low ripple and zero noise until around 250W and even then the RPM's are so low you won't hear it. The real competition within price and features would be the Seasonic focus and prime lines. It's a tough choice, both are excellent units. Seasonic PRIME is currently $10 more, has FDB hybrid fan and even better voltage regulation and MIR. Focus is $10+ less Purchase factor resides in current sales and/or MIR and personal preference [past history] To date I've never had a faulty Corsair or Seasonic unit, many are 5+ years old and still rock solid. Personally if I were to purchase today it would be a tough call but I'd go with 550W, I simply do not need that much power. If Corsair offered a 450W unit I might be inclined to save a few $$ and go that route if it supplied enough cable options. Empty connections are wasted connections but allow some future overhead. CPU/GPU are becoming less power hungry as time goes on and the best efficiency is actually running around 50% load per any tech site if that matters to you. Truth is between Gold, Platinum and Titanium you might see a few dollars power savings for an entire year so it's not something to overthink even running 24/7. I hope you find my review useful and thanks to Newegg for the chance to review this item.

Pros: + 80 Plus Gold efficiency + Relatively low price + 650 watts of power with a 54 amp 12 volt rail + FULLY modular + All Japanese caps, nothing cheap inside this thing + Virtually silent, even under load + 10 year warranty and Corsair support, doesn't get much more bulletproof

Cons: - Mix of flat and braided cables, would have been nice to see all braided or all flat - No test button

Overall Review: Not much really needs to be said about the RM series from Corsair - it's 100% mid-range and sets the standard for what you should be using in your PC, at the bare minimum. Personally, I prefer to AXi series as I utilize CorsairLINK to monitor temps and fan speeds (and control RGB lighting, of course!), but you should NEVER skimp on your power supply! For the money, this might be the best entry-level power supply out there. Plenty of power to run a basic system, but overhead to tackle even the heftiest single GPU build. You may have trouble running SLI or CrossFire with this PSU, but chances are if you're dropping over $1000 on a single or multiple GPU's, you're not looking at a $100 power supply. I had absolutely no issues with this PSU running my system (i5 4960k, GTX1080) and it survived 48 hours of full-load burn in with zero hiccups. I give the Corsair RM650x 5 out of 5 Eggs, it's an absolutely phenomenal power supply.

Pros: My biggest pro is this has 54 amp on the 12 volt rail Fully modular Standard size PSU....can fit older cases with ease as well as newer ones, I prefer standard size over sfx Stable even under full load whisper quiet fan 80+ Gold....PSU is rated for at least 87% efficiency at 20% load, 90% at 50% load, and 87% at 100% load

Cons: the cables should all be flat, braided cables are nice but i prefer flat as i can route the cables better behind the mobs tray.

Overall Review: I replaced an 450w corsair with this as I had trouble booting my computer when I switched from water cooling to all stock cooling. The added power draw from all the fans caused it to not boot with the old PSU but once I installed this it booted up perfectly fine. I even managed to overclock on my I7 slightly and still be within the power specs. Having 54a on the 12v rail is an big plus as this uses japanese caps, its able to supply a constant voltage without any damaging fluctuations. Overall I am very happy with this and will be getting another one for my sons build, 650w is the perfect balance for light gaming and general computer work.

Pros: PSUs today come in many wattages from 300-1600w. With such a large variety to choose from where does one begin? I’ve found in my experience that 1500-1600w PSUs are incredibly expensive ($450) and are best used in multiGPU + multiCPU systems. As you’ll imagine most people are not running such systems and instead finding the correct wattage for your setup is key. In my experience if you intend to run a high end CPU and GPU, you’ll need at a minimum 600w. 750w-850w is a nice investment if you want headroom or want to add peripherals later. I’ve found 450-650w can be used for mid range CPU + GPU combos, but really don’t allow much room for overclocking or load spikes.

Cons: There really isn’t any good reason to have a 650w PSU in an ATX form factor when silver stone and Corsair have 600w SFX PSUs which are a fraction of the size. I suspect the larger size for the CP-9020178-NA is more about ascetics as having a tiny SFX PSU in a full sized case would be silly

Overall Review: Therefore the CP-9020178-NA is just right in terms of having enough wattage to game, while being inexpensive enough that anyone can use it. However if you intend to have a second GPU or are serious about overclocking, get a 750-850w PSU

Pros: - Fully modular – plug in what you need, leave out what you don’t. - Stable voltage – if the rails are fluctuating at all, it’s beyond the ability of my meter to reliably measure changes that minute. - So quiet – I love this about all of the Corsair PSU’s I’ve tested and own. Even when you manage to get the fan to kick on, you can’t hear it above anything else that might be running in the case. (And my case is very, very quiet.) - Premium packaging – All of the Corsair PSUs come with a nice nylon bag with a Velcro closure to store cables you are not using. The PSU itself comes in a cool little velvet bag.

Cons: - Nothing

Overall Review: I’ve been running a Platinum Corsair PSU in my gaming PC for years and I’ve never had an issue. I put a Gold in my girlfriend’s PC, and one in her son’s PC. I’ve tested several of them over the years for Newegg and they have all been super stable and reliable. This one is no different. I stuck it in my main PC to replace the 1000w PSU in there for testing, and it ran just fine with no problems, despite being much lower wattage. 1080 gtx, i7 cpu, gaming on just like it did with the old PSU. I have no issues recommending Corsair PSUs for your build, they work great and you can’t hear them doing it.

Pros: Reputable brand with a high efficiency design and cool features. Quality long time capacitors help ensure a long life span as this is a common failure point low quality power supplies. Corsair is known for quality fans and it's quiet, standard 140x25 should you need to replace it. More efficient than previous generations, idle line draw is reduced when compared to a previous generation RM unit. Corsair software is easy to navigate and provides a lot of information, amazing for enthusiasts or those desiring to learn more. I notice in my situation the fan rarely turns on and is silent when it does, at full speed it's audible but not over my graphics card. Modular, this is a must for myself as it removes the majority of bunched up extra cables. 10 year warranty? --- This is investment grade. Build quality, as expected everything fits, everything works!

Cons: Connectors are not gold plated, this isn't a concern point but would be nice at the premium level. SATA and 4 pin wires are not sleeved like the others.

Overall Review: My power supply is at the bottom of the case and isn't used for heat evacuation so it's of benefit that the fan will disable when it's not required This power supply will run a long time without needing to be cleaned and I'll have the knowledge it's using a little less power not using the fan when it's not required. On the other side if I relied upon it for additional cooling I could lock it at 100% or setup a custom trigger and ramp. Beyond the capabilities of and with more accurate triggers than classic fan controllers which were not designed to control power supply fans. Nicely packaged high quality power supply with a slew of extras available via software. Corsair has been a go to for me for about 10 years (fan boy?) maybe and with reason. Corsair warranty service and support is second to none, the community is strong and supportive as well.

Pros: When I first got this delivered, I was like a kid in a candy store. The box was heavy, meaning I knew the power supply was going to do the job I needed with the small compact space it needed to fit inside the case. * Fully Modular Power supply so it is easy to hide the wires for a great display inside the case and help with airflow. * The cables are nicely braided in a mesh sleeve. This was a huge plus when looking for a modular power supply that was 80 Plus Gold. * The power supply does not make any noise. This is super quite. I believe a lot of this has to do with the zero fan usage unless the fans are needed for a power hungry application or during gaming. * The size of this is very small. This is just 160 mm in length. Fits nice inside the standard case. * Looking at the back of the power supply, you can see the high end parts that are copper. * This will seriously save you some coin over the traditional power supply. This is rated at 80 PLUS GOLD so you will notice this over the course of a year. This is very efficient and with the zero fan, the fan wont spin unless needed - also saving you some money. * Corsair is a tired and true manufacture! Look at the amazing warranty - 10 Yrs!! That is buying with confidence!!

Cons: None it is CORSAIR!

Overall Review: If you are building a PC for everyday use or a gaming PC that wont need three SLI Video cards, then this is for you. You will get this power supply knowing that the years you own your PC, this will be covered under the long 10 yr warranty and assurance that Corsair is not going away anytime soon, you can buy this with confidence. The confidence is not only in the warranty, but in the high quality of Corsair products. If you found this helpful, please click the yes button.
