Discover the MWE Gold 1250 V2

The MWE Gold 1250 V2 is engineered for high performance and reliability. Its 80 PLUS Gold certification guarantees high efficiency (≥90% at typical load), reducing wasted energy and heat generation within your system. With a massive 1250W capacity, it provides ample headroom for power-hungry components, including multi-GPU setups and heavily overclocked processors. Active PFC and stable voltage regulation ensure consistent power delivery under demanding conditions.

Building and cable management are simplified thanks to the fully modular design. You only connect the cables you need, resulting in a cleaner interior, improved airflow, and easier maintenance. Moreover, the MWE Gold 1250 V2 features a large 140mm fan with a durable Fluid Dynamic Bearing (FDB) for long life and quiet operation. Impressively, the fan remains completely silent (0 dBA) at lower loads (up to 20%), only spinning up when necessary. Explore other modular power supplies here.
