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.

The value for the money is great. For anyone on a budget this is a solid choice. It fits well, and it’s easy to install. It performs as it should, with enough cables to power everything you need. It’s not modular, but it is perfect for mid tier builds. I recommend it.

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

At the moment, it has worked perfectly fine for me. I’ve yet to have any issues and it performs extremely well for its price range. Overall 9/10

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.

A good PSU. I would have liked two independent PCIe slots and cables as many gpus especially ones over 200w require two.
