Replaced a 600W in a Lenovo Legion T5 where the mobo was lost. Easy install, quiet, and the power is spot on, zero discrepancies. If that changes, I'll update: I prefer 100% modular but having it modular outside of the primary power rails in an NZXT H9 Flow saved me some money; the case hid everything well, so going full modular wasn't necessary and I was able to invest in a fan hub and stay within budget. No vibrations, zero rail discrepancies, super quiet, and the modular use outside of the mobo requirements are nice. Value is spot on, connectivity on both ends is great, it looks awesome, the cable quality is better than a Raidmax I once tried (and the CoolerMaster it replaced), and managing even the stiffer primary cables was easy. I'm giving this thing 5-Stars outright due to the simple fact the power has zero issues. Perfection in that regard. Well done, Corsair; impressive.

Very happy with its performance. The semi-modular design made cable management a breeze—only plug in what you need, which helps keep the case clean and airflow efficient. It runs very quietly, even under load, and has been rock solid in powering my system with no issues. Cable mangement looked nice when finished. The build quality feels premium, and it comes with all the necessary cables and clear instructions. I also appreciate the 80 Plus Bronze certification—perfect for mid-range builds or even higher-end setups that don’t need extreme wattage. Highly recommended for anyone looking for a dependable and affordable power supply!

I'm one of those that uses pc's until they die. So currently I'm using an A88X-Plus motherboard with a 15yr old AMD A10-5600... Don't need to upgrade quite yet. Not a gamer or a streamer.. Turns out I was under powered for the longest time and trying to run that board and cpu on a 300w power supply when the motherboard manual clearly stated 300w is enough for standard operation without cards and extra drives.. Decided to buy this for a modern pc build as parts go on sale. I'll buy.. until then. I'm using this psu in my old dinosaur AMD system and for the first time it it's little life. It's getting the power it needs... have it funning in optimized and ultimate power settings and all my lags and glitches are gone! And this thing is dead silent. Cables are plenty long enough. only lacks more sata connectors. only has 3 on 1 cable.. so get extensions

I needed to replace the 10-year old Antec 380W PSU for my modest build: Ryzen 2200g with integrated graphics, 16 gb memory, M2 nvme, and dvd drive. It had evolved over the years to that configuration, with the Antec PSU being the oldest part still standing. It hadn't ever failed or caused any kind of problem. But it's exhaust air at idle had become warm enough to hint that it was on its way out. At the time I ordered it, the Corsair cx650m was a very good deal: less expensive than the similar 550, with the 450 being unavailable at any reasonable price. But I was concerned the 650 would be less efficient than the 450 for the modest power my machine used. It seemed outlandish to have a psu that was rated at four to six times the power required. A comparison at a few popular hardware-test sites showed that the efficiency at my typically low power levels was practically identical for the 450 and 650 -- and quite good by any standard. All the corsair cx-m units had glowing reveiws after what looked like very picky examination and testing. I was also concerned that having an "overpowered" psu could somehow damage my computer. A little reading showed that's not normally a worry. In addition, the cx650m passed all the limit / protection tests the experts threw at it. Although I wasn't able to confirm this, it also seems reasonable that a power supply will last longer if it's just coasting than if it's under a heavy load all the time. Maybe, maybe not. We'll see. Installing the CX650 was a breeze. It powered up with no problem, and the exhaust air was cool. If I put my ear next to the case, I could barely hear the fan at idle. (Corsair advertises that the fan speed is constant from 0 to nearly 400W.) With the computer under the desk, I can't hear it at all. Any ATX build needs at least the two fixed cables that are on the unit. My dvd player required one of the five additional modular cables that were included. So the interior of the case is much less cluttered than before, presumably with better air flow now. With luck, the bit of web research and this review will be the last thoughts I give to power supplies for the next ten years.

I have been using Corsair brand power supplies for over 20 years when I build new systems for customers. They work and I like them.

Nice working power supply, and with black sleeves instead of the ketchup and mustard ones. It runs quietly in the unit I put it in, as it should fit most cases as long it not a small format case. Only thing is it not modular unit so keep that end mind you might have to deal with cables your not using as far cable management.

The power supply is very good. Even though it's semi-modular MOST people are going to be using cables that can't be removed anyway so it doesn't really matter in my personal opinion. When it comes down to noise level there's barely none as far as it goes for me. And I tested the sound with an open case. Meaning when the PSU IS enclosed it's even more silent. The build quality is also good and feels like a premium Power supply. And the cherry on the cake it comes with all the cables you would ever need which is neat. Overall Best PSU for for the price. And would highly recommend.
