★★★★★Corsair quality is next level... they are my go-to for serious machines.
This thing is a beast. the cables are top notch.. i had enough to connect my 7900XTX with 3x8-pin connectors. excessive amounts of SATA and and peripherals connectors.. you will never need that many but its nice to have them. unit is heavy and does an excellent job and heat dissipation. its quiet and outside remains cool. Corsair has kept an excellent quality standard over the years, where many competitors have fallen off... looking at you TT. couldnt be happier with this PSU. AMD Ryzen 5 7800x3d, MSI B650 Tomahawk, AMD 7900 XTX 24g, about 5 full size chassis and case fans, full ARGB internal lighting and rails, no issues with power or heat. solid PSU!

★★★★★Perfect!
2 years ago I built a new gaming PC and wanted to do a white build. At the time I kept my old graphics card which stuck out like a sore thumb because everything else was white but my graphics card. Recently I ended up getting a white Asus 4070 TI OC card and at the time I never even thought about recalculating the power requirements to go with the much bigger card upgrade. I was noticing game crashes that never crashed before or my computer just completely shutting down. I eventually took everything apart to see what was causing the issue and then I notice the PSU wattage and was felt like an idiot as soon as I realized I was overloading the old PSU since the power draw on the 4070 TI OC was a lot more than my old graphics card. Pretty much everything in my computer was either Asus or Corsair so I figured I would find a new Corsair PSU and the moment I saw the white one, I was like YES! This is exactly what I needed. I haven't had a game crash, PC crash or anything since replacing the old PSU with this one.
