Reviews
Power stays rock solid even during long gaming sessions with my RTX card pulling hard. The fan runs quiet most of the time and the black cables look neat inside my case. I feel confident it protects my parts well.
My new build runs cooler than before thanks to this supply. It handled the spike when I upgraded my graphics card without any flicker or noise. Setup was simple and everything stays stable for hours of work and play.
Compact size fit perfectly in my small case. Cables reach all my drives and the power feels consistent. The fan keeps things from getting too warm but I wish it stayed completely silent at very low loads.
