> 3 dayPerformance-wise, cant say anything negative about the power supply. Rock-solid voltages, 80+ Gold and dead-silent. I dont think Ive ever heard the fan. Plus, beautiful white for white builds.

08-06-2025Consistent and reliable power delivery for a high-demand system. The white color is a necessity for certain aesthetics ;)

> 3 dayOrdered one to fit into my system to use my new 3080 and I (foolishly) installed it before testing it. Turned out it wouldnt power on at all. Tried replacing it and the replacement had the same issue.

Greater than one weekWere testing a new board and need a reliable +3.3V rail. This PSU has it! Through my testing Ive found that most low-end PSUs do not have reliable +3.3V rail. When you get into higher-end units like this, they are pretty consistently doing the job well.

> 3 dayI bought this to replace my old 1000W Coolermaster power supply. Im extremely happy with it since it provides great power and remains quiet even during gaming!

03-06-2025Neat and easy to install. The modular disign and flat cords keep everything neat and tidy. Needed more power for a new video card. This power supply works perfectly.

> 3 dayI carefully installed this PS, but the MB wouldnt fire up. Installed an old PS and it worked. I checked it with a PS checker, no 12 volts. Returned it to Amazon and got a refund quickly.

> 3 dayThis looks sharp and performs well while being very quiet. Cable management on this PSU is solid. I liked it enough that I bought a black version for another build but I have to admit the white is pretty nice.
