Super Flower Leadex V Platinum Pro 1000W Power Supply Review

With only 130mm depth, the Super Flower Leadex V Platinum Pro is the smallest 1000W ATX12V PSU.

Super Flower managed to raise some eyebrows with its new Leadex V Pro line by delivering a 1000W ATX12V compatible PSU that's only 130mm in length. If it weren't for the SilverStone SX1000 SFX-L unit that we reviewed a while ago, we would be hugely impressed by the super-compact dimensions of the Leadex V Platinum Pro 1000. 

Nonetheless, such small dimensions require compromises in noise output since a small diameter fan has to be used, and the small PCB needs increased airflow, so the fan has to spin at high speeds under high loads. We prefer a normal-sized PSU with lower noise output.

The overall performance that the Leadex V Platinum Pro 1000 achieves is on par with competing offerings, and with a better transient response on the minor rails, it would score even higher. We would also like to see over 70% efficiency with a 2% load and lower Power-On and PWR_OK delay timings. 

Moreover, the use of 20AWG gauges for the second PCIe connectors on cables with a pair of them is against the safety standards that the ATX spec sets, and Super Flower should replace them with 18AWG gauges as soon as possible. It would be best not to use these connectors for power-hungry graphics cards. Some notable competitors of this Super Flower model, with lower noise output, are the EVGA SuperNOVA 1000 P6, the new Asus Rog Thor II 1000 model, and the Thermaltake Toughpower Grand RGB 1050.
