A qualidade é excelente.
Atendeu todas as espectativas. O que aconteceu de ruim foi que entrou em promoção no dia seguinte, fiz uma nova compra e não consegui cancelar a do dia anterior, mesmo com menos de 12 horas de diferença. As duas entregas vieram e rejeitei a que estava fora de promoção, para que eu pudesse seguir somente com a de valor promocional. No geral, essa fonte é uma nave, e desde então, não tive mais problemas com o PC reiniciando.

Worth the price !!!
Pros and Cons as well as the overall rating at the bottom This PSU delivers stable, efficient power with low noise output, making it a strong choice for systems running high‐end GPUs like the RTX 4080, 4090, and upcoming 5000‐series cards. Despite being marketed as an 80+ Gold unit, real‐world testing shows efficiency levels that often approach Platinum territory, which is impressive for its price class. The PSU's compact size makes installation easier in mid‐tower and full‐tower cases, and the fully modular cable system helps keep builds clean. The included flat ribbon cables are long enough for larger cases, though they can feel stiff during initial routing. Still, once installed, they contribute to a tidy, airflow‐friendly layout. Noise performance is one of the RM1000e's standout strengths. The 120 mm rifle‐bearing fan remains off during light workloads thanks to Zero RPM mode, keeping the system silent during browsing, media playback, and light gaming. Under heavier loads, noise levels stay controlled and rarely become distracting. Electrical performance is solid, with stable voltage regulation and low ripple across all rails. Thermal behavior is also well‐managed, even during extended stress tests. The native 12V‐2×6 connector ensures full compatibility with modern GPUs without adapters, which is a major plus for long‐term reliability. The RM1000e a great value when discounted, but less compelling when priced close to its RMx sibling. Overall, the RM1000e (2025) is a quiet, efficient, modern PSU that fits well in high‐end builds and offers excellent real‐world performance for the money. Pros .Fully modular design with clean cable management .Very quiet operation with Zero RPM mode .ATX 3.1 + native 12V‐2×6 connector for modern GPUs .Compact size fits easily in most cases .Efficiency often near Platinum levels Cons .Flat cables can be stiff .RM1000x offers slightly better components for a small price difference .Slightly weaker performance than the RM1000x series Overall rating A+

Corsair never disappoints.
Worked like a charm. Bit on the pricey side, but you get what you pay for here.
