    I was in the market for a PSU. It seemed like all the power supplies have have gotten more expensive and they did not have many features but this one had the features I wanted and it was inside of my price range.

    So far so good, the all black cables feel like they're good quality. Semi modular, which means less of a cluster of wires than previous PSU.

    Bought this to fix an old Dell XPS 8900 for a friend. The power supply fit just fine, and the cables seemed to have good quality. I would recommend Corsair as I've used them for every system in the last 5 years and every power supply by them is still working.

    Already owned a 750 watt for years in another PC with zero problems so when a Thermaltake 750 died after only a couple of months ( it was new, I had it for years in the closet for a backup) I didn't even look at anything else. The Corsair is the winner.

    So far so good, tbh I think I might be pushing this one to it’s max but I haven’t had any heating issues or cut-offs, cooling seems to be getting the job done. Running a ryzen 7 7700x Radeon 6750xt 6 rgb fans Msi 240mm liquid cooler with display I haven’t overclocked or undervolted as this is my sons pc and he plays Roblox and records Just running it at base and temps stay colder than a ice cube
