  • This build has high demands, especially with the spikes of the 7900XTX and the voltages of the 13700KF. The HX1200i doesn't flinch. The voltages remain "rock solid" even under full load (4K gaming or rendering), providing the security you need for such expensive hardware. The Platinum certification helps a lot in keeping the power supply cool and not wasting electricity unnecessarily.

    This review is about the power: 1500 W

    Purchased to be installed in a machine with an RTX 5090 and Ryzen 9950x3D. Stable in every aspect. Even at full load, surprisingly, the fan did not need to operate, which shows that it maintains good temperatures. Excellent build quality, especially of the cables. Very good decision to include braided cables as they are by far more flexible than the classic plastic ones.

    This review is about the power: 1500 W

    Coming from an HX850i (which has been working perfectly for 10 years), I upgraded to this because of the RTX5090. The maximum load I saw was 1020w with excellent efficiency and very low noise. A real beast.

    I remove one star because the power cable is unusual, it is not the standard one. The plug that goes into the power supply is larger than usual. If the cable is lost, it will probably be difficult to find another one.
