CX550 80 Plus Bronze, Non-Modular ATX Power Supply, Low Noise 550 W, Black

Corsair never disappoints. This CX650 is whisper-quiet, runs cool, and powers my system with no issues at all. Cables are long enough and feel good quality, installation was straightforward, and there’s been zero coil whine or instability under load. It’s also 80 Plus Bronze certified, so efficient too. For a mid-range build, this is a fantastic power supply — great value and rock-solid reliability.

I recently installed the CORSAIR CX750 80 PLUS Bronze Non-Modular PSU in my PC build, and it has been performing perfectly. It delivers a solid 750W, which is more than enough to power my components without any issues. The unit runs quietly, even under load, which is a big plus for me as I prefer a silent setup. The build quality feels robust and trustworthy, and the 80 PLUS Bronze efficiency rating gives me confidence that it’s not wasting power unnecessarily. While it’s non-modular, I found cable management to be manageable with some careful planning. Overall, this PSU has been reliable, efficient, and quiet—exactly what I was looking for. Highly recommended for anyone building a mid-to-high-end system.

Works amazing and neat wires

I'm using this in an admittedly huge case, the Fractal Pop Air XL. The PSU only has one cable for SATA power with three connectors on it and it doesn't stretch between the 2.5" and 3.5" bays, I've had to buy a couple of SATA power extension cables to power my drives. Interestingly it has a long cable with 2 Molex connectors which can't see much use these days. The other cables just about stretch to where they need to go when routing behind the motherboard, some quite extreme angles needed on the cables though. It's decent quality and it's a good price but if your building in a large case maybe look elsewhere.

I'm not going to lie. I wasn't very impressed with the packaging of the product. (IE there was none at all from Amazon). Feels wrong to deduct a star for this - but Amazon should be doing a better job protecting electronics. [in hindsite the £3 extra to insure it for 3 years is worth every penny for peace of mind] It's smaller than the CX750 it's replaced in the computer I'm building for my son, but still fits into the case without issue. It is non modular, so all the cables need to be facilitated within the case, but again I feel this is presented better (certainly more manageable) than the old PSU it replaced as it was a lot easier to secure the xcess cables. Great price from Amazon. And so far it's working without issue.

I learnt years ago that a decent power supply from a decent name such as Corsair ultimately saves more headaches and money in the long run than a string of budget/cheap PSUs. Yes they cost more money in the first place, but they last far longer. Budget PSUs might be cheap, but if (or when) they pop, they tend to take your system with you, assuming they can pump out what they claim in the first place. Anyway having upgraded my hardware (from a Ryzen 3 1200 to a Ryzen 5 5600 and a GTX 650Ti Boost to a 3050) so that I could upgrade to Windows 11 and run Cities Skylines II at a semi-decent frame rate (while not have everything in the game look like it was made out of plastic), my previous 480w unit wasn't quite enough to power it, as I found out when the computer spontaneously restarted after 5 minutes of gameplay and not through blue screen either. Usually the voltage drops and that reduces the amount of power available, so the computer can't run and its as good as hitting the reset button at that point. The Corsair 750 does what it says on the tin - provides 750w of power- and like most computer components if you know what you're doing, its a piece of cake to swap out. Swapped it out, plugged everything back in, powered it up. Fired up Cities Skylines II and the computer ran for 3 and a half hours in the game without falling over once. The length of the power cables aren't particularly generous I have to say, which may be an issue in a larger case. All the connectors you need are here - three SATA (all on the same cable), two legacy four pin ones, and your standard 20/24 pin, CPU power 4/8 and two PCI-express x6 connectors. The trend towards M2/NVMe devices and no optical drives may mean you don't even need the SATA connectors anyway. Like most decent power supplies it doesn't sound like a hovercraft when in use either. You can't go wrong with a Corsair if you're in the market for a new unit (by choice or otherwise). If in doubt about your power supply needs, get a higher wattage unit - your hardware will only takes what it needs.

Das Netzteil (Corsair CX750 80 Plus) selbst funktioniert einwandfrei, aber geliefert wurde ein Kabel mit dreipoligem UK-Stecker – ohne Adapter oder Alternative. Für Deutschland völlig unbrauchbar! Ich musste extra ein passendes Kabel dazukaufen. So etwas darf bei einem Produkt für den deutschen Markt nicht passieren.

Short circuit my motherboard and melted the pcie slot on the motherboard. I have to replace the motherboard and this power supply.

Passt alles super. Im Rechner eingebaut und läuft seit einem halbe Jahr problemlos

Impecable
