    Replaced a very old power supply. The fan on the Corsair RM1000x comes on when the power supply is delivering over 400 Watts, and it hasnt come on in the first month of use. This full modular power supply, properly installed, has no unused cables. Lots of reserved power in a standard ATX power supply form factor.

    The power supply unit was dead on arrival. I waited 2 weeks for this power supply unit to arrive, and almost half a year for a decently priced power supply unit. Amazon can’t replace the power supply unit and 10 year warranty means nothing if it’s just dead on arrival.

    I used this product to replace the PSU in my Dell Studio pc. It fit, but not perfect. Also, the fan is very noisy but it works.
