    This PSU remains quiet and stable even under load. Can’t beat 10 year warranty and so far exceeds my expectations. It has 5 pcle 8 pin connectors in addition to the mobo and cpu. Great product.

    Works well with a RTX 3080. No issues so far! Always go Full Modular, if you can. This is a bit more pricey than other PSUs but the warranty and Corsair reputation is unbeatable.

Its 80 PLUS Gold certification ensures a level of energy efficiency that won't disappoint, while the fully modular design keeps cable clutter to a minimum. Though it lacks any groundbreaking innovations, this power supply's consistent performance and sleek black finish make it a reliable companion for any PC build.
