### ⭐⭐⭐⭐⭐ Rock solid, modular, and super quiet
*by K***Y on February 18, 2026*

The power supply went bad on my iBuypower PC and I asked Rufus what a good replacement would be and he recommended this power supply. The only negatives I see in other people's comments were that the cables feel cheap, but I disagree, they do feel thinner than the permanently mounted ones that you see, but they're made from a material that is more flexible then cheap hard plastic. I had spare length on every cable as well. My PC has the following specs: • Processor: Intel Core i7-14700F • Graphics Card: NVIDIA GeForce RTX 5060 (8GB GDDR6) • Memory: 32GB DDR5 RGB RAM (5200MHz) • Storage: 1TB M.2 NVMe Solid State Drive • Motherboard: B760 WiFi The power supply connected perfectly and powered right up. I couldn't be happier with this and would recommend it!
