"So I'm going to be as kind as a plus we can in this because I do not feel that it is the seller's fault that this happened now let me run you through how my purchase went I ordered the power supply for my computer it arrived on time well packaged I installed it had no problems and for about 3 months it was a good power supply I was sitting at my computer watching a video and started to notice a sizzling sound coming from the back of my computer I look up and notice smoke it starts crackling so I tap the back of the computer gently thinking that maybe some dirt or something had gotten in the way and a big flash shot out the back of my power supply, now if my power hadn't already went off on my computer I would have turned it off as quick as possible I instantly shut off everything uninstalled the power supply and put my previous one back in which eliminates me being able to use my graphic card, so anyway I contacted Amazon and I feel that this is not their fault either as they did try to help me with the situation but they had informed me that I did not pay for a protection plan but I was still in the time period to return the item and receive a refund all I would have to do is wait for an email and then ship it back what's the email never came so here it is almost 4 months after buying the power supply if I do recall and I still have a dead power supply so I decided to take it apart it turns out that the circuit board was broken in transit I further investigate the power supply and it turns out that the circuit board was so low to the metal that it started to heat up causing the burn mark that you see in the picture, now again I don't feel that this is the sellers issue and I don't feel that this is Amazon's issue I feel that it was an issue with Transit but what am I to do I do not know still currently without a power supply to be able to run my graphic card I feel that I am out of the amount that I put into it and have nothing to show for it it's sad but not sure what to do on the matter it is up to you rather you feel that it's a good purchase honestly while it worked I absolutely loved it for the power supply itself I would have to say it is a really good purchase if it is handled with care."

I’ve been using the Corsair CX650M in my build for a while now, and it’s been exactly what I hoped for in a solid, no-nonsense power supply. The semi-modular design is one of my favorite parts — you only plug in the cables you actually need, which keeps the inside of the case much cleaner and makes airflow better.650 watts is plenty for most mid-range systems, and this unit handles things without breaking a sweat. It’s not crazy expensive, but it doesn’t feel cheap either. It has enough juice to run a decent GPU and CPU combo comfortably, and I haven’t had any stability issues, even when the system is under load.Noise levels are low, which I appreciate. The fan stays quiet during normal use, and even under heavier load it doesn’t ramp up to an annoying level. It’s one of those parts that just does its job without calling attention to itself.Build quality feels good too. Corsair has been around forever in PC hardware, and this PSU shows why. The wiring feels sturdy and the connectors are solid — nothing flimsy. It also has the 80 Plus Bronze efficiency rating, which means it wastes less power and runs more efficiently than basic units.All in all, the CX650M is a dependable choice if you want a reliable power supply that’s easy to work with, stays quiet, and supports a wide range of components. If you’re building or upgrading a mid-tier gaming or productivity PC, it’s a power supply worth considering.kavan

Purchased on sale for my older build that needed more power for a graphics upgrade, this fits perfectly, love it that you only plug in what you need and enough power for my use case.l davis

This power supply replaced an old psu that didn't have the capacity to power an upgraded desktop computer. It was easy to install and runs very quietly. With the semi-modular design I only had to install two cables (a sata cable for the drives, and a cable to power the graphics card), so the case (which was built in 2001 and is on its third or fourth motherboard) is a lot less crowded than it was before.What Customers Talk About
