Super Flower Leadex VII PRO 1000W ATX v3.1 PSU Review

Epilogue

The Super Flower Leadex VII PRO 1000W is currently sold for $230, so you cannot call it affordable. Nonetheless, a 1000W PSU is destined for a strong system equipped with expensive parts, so you should not go cheap on the PSU but buy a high-performance and reliable one. Remember that the PSU will be without for several system builds, aging much slower than other PC parts, including CPUs and GPUs.

The Leadex VII PRO 1000W achieves a decent overall performance, but it cannot threaten the competition from 1st Player, Asus, Corsair, and Montech. Even the Leadex VII XG 1000, at least the sample I evaluated, achieved a higher overall score. The not-so-good ripple suppression, mostly on the minor rails, the average transient response on the same rails, the increased vampire power consumption, the not-so-high PF readings at 230V, and the low-efficiency 5VSB rail cut performance points from the overall score. On the other hand, the platform achieves high average efficiency, it has extra-tight load regulation on all major rails, the 12V rail’s transient response is good, especially in the “heavy” ATX v3.1 test scenarios and the hold-up time is way longer than the required. On top of that, the PSU is equipped with many cables and connectors, and its dimensions are compact, thanks to the 150mm depth. Despite the compact dimensions, there is plenty of room between the platform’s components for good airflow, and the high efficiency also helps keep the noise output because it lowers the thermal loads. The average noise output is high, at nearly 35 dBA, but the PSU’s fan goes wild at high loads. The PSU operates quietly at light and moderate loads, with its fan’s passive operation lasting long.

I would like to see some issues resolved since they are significant and belong to the protection features segment. To effectively protect the PSU, the 12V OCP and OPP triggering points should be further apart under cold and hot conditions, and the inrush currents have to be lowered by using a larger NTC thermistor or by installing an additional one to increase the total impedance.

The Super Flower Leadex VII Pro 1000W is a good power supply, but its price doesn’t help it achieve a high performance-per-price ratio. Super Flower should either improve performance, which I believe is possible for its team, or drop the unit’s price below 200 dollars to make it more attractive.
