Its a good power supply, its very quiet comes, with a little baggy for your extra cables. My only issue is that it does start to get a bit noisy once you start playing games but that to be expected from every power supply

Not much to say about this, its a power supply unit as described. It works as advertised and fit nicely in my NZXT 510 case. Comes with all the cables needed to supply power to everything in the pc including MOBO, CPU, GPU, and SATA power.

Good price for a power supply. There is plenty of wattage, so this thing will never have to work very hard to supply power to a MoBo and a SSD. Many cables included, so if like me, you bought a few of these, you will have many extra cables leftover.

What a lovely power supply, so nice having a fully modular PSU.
Only negative is that I have to say is that after unboxing it had a horrid fish smell coming from it, I had to air it out before installing it in my computer

Amazing modular power supply!! Dont know what that means, well, it means that the days of your computer case being filled with unneeded cables that require you to tie them down or fold them up are gone!! Attach and use what you need

And all the other attachments to my wife's new computer. Waiting for the NVIDIA 3070 to be available for a complete system. That may put additional stress on the power, but having used several Corsair 850 watt supplies with out a failure in over 30 years of building my own computers, I doubt this 750 will be maxed out at any time. Buy it if you can find it.

I bought this for my gaming pc. This is a great product and overkill for my rig but for the value and the quality I have no complaints. I never hear it running and it works great! Love Corsair's products.

It’s a great power supply, it’s fully modular, the only down side is that it does not have sleeved cables like my evga power supply. But this power supply is for my sons first pc build and he is happy with it.

Upgraded sons gaming computer. Another great product by Corsair. If you are doing a power supply upgrade always go with a modular. Much easier install.

This was the next cheapest power supply available that would work for my pc build. It had well enough power and modular cables. Probably a lot more than I could ever use. It is an 80 Plus gold which means its supposed to be quieter and more power efficient I believe. I liked knowing that. I've never been able to "hear" a power supply on anyone's computer so I don't think noise is really something you need to worry about with this power supply. When you look through the fan hole at the top of the power supply you can see insulation around the walls which is clear it's for sound or heat. I really like the modular cables. I never thought I would need them, but now they are a must. I no longer has to push 5 million cable I'm not using into a space that's too small or into space that isn't there. If you don't buy this power supply, at least make sure you buy a modular one!

Corsair being a respectable brand known for making quality PSU's. Without a doubt worth the money, all the cables felt premium and i noticed that this one has a ton of ports and connections, if you're plugging a lot of things in.

Modular is definitely the way to go when building a PC, especially if you plan on upgrading and / or adding components in the future. Keep the extra capable expressly for that purpose!!!

A good power supply but with no bells or whistles.
Standard looking cables and no fabric bag for cables, unlike their other lineups.
Performs well though, is quiet, and has enough power for the majority of builds out there. A solid choice for anybody looking to build a mid-range desktop.
I’m currently using a 10700K (not overclocked) with a 3090 with no issues and power to spare.

Had this in my machine for over a month now powering my OC'ed 10600k and RTX 3070FE with no issues whatsoever. Everything was clearly labeled and easy to hook up. I've had no weird power fluxes or blackouts either.

Modular power supplies are amazing if you truly care about wiring. I appreciate that you don't get ketchup and mustard cords. They are sleek black all the way and helps bring my Black Build together nicely

Replaced CX750M

I used the CX 750 M power supply from corsair and my computer would randomly shut down during full load. After a while of searching for a replacement, i chose this one.
My computer stopped shutting down during intensive load and is more quiet.
plus it has a 10 year warranty.
i’ll update if anything is to change.
