So Super Flower can deliver high quality in a chic look at attractive prices both for the power supplies sold under its own brand name and for the models made for other brands. Consequently, it is hardly surprising that Super Flower power supplies are often recommended by well-known trade media as well as by satisfied users.
The Leadex series marks the successful introduction of the manufacturer into the real high-end segment: With outstanding performance at low volume, the Leadex family sets the standard for performance power supplies since the end of 2013. With the all-new Leadex III series, Super Flower is now renewing and renewing the fully-modular 80 PLUS Gold power supplies. Both the optics and the technology under the hood have been improved once again to set the standard in the performance segment in the future.
The features of the Super Flower Leadex III 80 PLUS Gold 750 Watt power supply
- Fully modular power supply with 80 PLUS Gold certification
- Three operating modes for quiet and efficient cooling
- Quiet 135mm fan
- Fully modular cable management
- Seven years manufacturer's warranty
- 2x 4 + 4-pin EPS12V / ATX12V / 4x6 + 2-pin PCIe / 8x SATA / 4x 4-pin Molex
- Low noise thanks to two semi-passive modes
Under the hood, the new Leadex III platform is now available on all models from 550 to 850 watts nominal power - of course from our own development and production. Compared to its predecessor, the volume of the fan and thus the noise emission of the entire power supply was significantly reduced, because the fans use the Fluid Dynamic Bearing technology in their warehouse. By switch on the back can now be selected between three instead of previously two different cooling modes. The active cooling always keeps the FDB fan running at high RPM.
In addition, there are two semi-passive modes, which are based on two different temperature thresholds: The fan is then, depending on the temperature at low to medium load permanently quiet. At the first stages called ECO 0, the fans start as soon as the temperatures are between 62 and 68 ° C. If they fall again below 47 to 53 ° C, the fan stops again. In ECO 1, the temperature threshold at which the fans start up is 42 to 48 ° C, the lower threshold is then 27 to 33 ° C. Due to the low fan speed and the FDB bearing, the power supply remains extremely quiet even during active operation. FDB bearings work noticeably quieter in comparison to conventional ball bearings, while they also clearly outperform plain bearings in terms of service life.
State-of-the-art technology, high-quality components
All Leadex III Gold are 80 PLUS Gold certified, guaranteed to deliver over 92 percent efficiency at medium load. At a low load of 20 percent, at least 90 percent efficiency is achieved, at full load it is after all 89 percent. As a result, the third-generation Leadex power supplies are clearly one of the most fuel-efficient voltage transformers in the future.
To achieve the high efficiency, Super Flower relies on state-of-the-art technology: the Leadex III platform, like its predecessors, relies on LLC resonance conversion in the primary area and DC-DC down conversion for the + 3.3 and +5 volt rail , With this form of independent voltage regulation, the output voltages will always remain close to the setpoint even in demanding test scenarios (e.g., asymmetric loading). If required, the total rated power can be retrieved as a + 12 volt voltage. In combination with the low ripple, Leadex III are therefore particularly suitable for demanding configurations and overclocking projects.
When it comes to the assembly of semiconductors and capacitors, Super Flower clearly places emphasis on quality: on the motherboard, only 105-degree electrolytic capacitors from Japanese brands and polymer-solid capacitors are used. The modular cable management board will also be equipped with 105-degree electrolytic chips from Taiwanese A-brands. In combination with the sophisticated fan control and the long-lasting FDB fan, the average life expectancy exceeds 100,000 hours. With overvoltage and undervoltage protection (OVP, UVP), short circuit (SCP), overload (OPP), overheating (OTP) and overcurrent (OCP on the + 3.3 and + 5 volt rail), the Leadex III in case of emergency always to protect valuable hardware (and yourself) from damage. Since Super Flower is easy to give all models of the Leadex III series full seven-year manufacturer's warranty.
As with all other Leadex power supplies, Super Flower relies on fully-modular cable management and completely black cables. So only the cable strands are connected to the power supply, which are actually needed. Already offered here 750-watt model has a rich cable equipment: In addition to the 20 + 4-pin connector for the motherboard are two 4 + 4-pin connectors for the processor and two cables with a total of four 6 + 2-pin PCIe connector for the graphics cards ready. The other components may be supplied with eight SATA and four Molex connectors.
In short: the third generation Super Flower Leadex is even more economical and quieter than its predecessor. The new edition delivers even better tensions and convinces with new features and the extended warranty period of seven years.
