Tom's Hardware Verdict

With only 130mm depth, the Super Flower Leadex V Platinum Pro is the smallest 1000W ATX12V PSU, but this leads to increased noise output under stressful conditions.

  • -

    - Lower than 70% efficiency with 2% load

  • -

    - Increased leakage current

The main asset of the Super Flower Leadex V Platinum Pro 1000W is its limited depth of only 130mm, making this PSU ideal for small chassis accommodating powerful systems. Performance-wise, the product hangs with direct competitors, including the EVGA SuperNOVA 1000 P6 and the Thermaltake Toughpower Grand RGB 1050W. Its major downside is the increased average noise output, which doesn't allow for a place in our best PSUs article. If you need a silent PSU, better look at the Asus Rog Thor II 1000 and the SilverStone Strider Platinum models. 

With the Leadex V P130X, Super Flower wanted to show that it can downsize its PSU to the degree that nobody else has so far, in the ATX12V form factor at least. Besides the super-compact footprint, another notable feature of the Leadex V is the 50-degree Celsius temperature rating. Typically, such a rating means that the PSU can continuously deliver full power at this temperature without breaking. 

Compact PCBs and good airflow don't get along. In a 1000W PSU, thermal loads are increased at full power, so most manufacturers avoid claiming high-temperature ratings, which can easily backfire if the PSUs are used for mining operations. Seasonic also has a 50-degree rating for its Prime PSU products, but a sidenote states that its PSUs can only deliver 80-percent of their capacity at such high temperatures and provide a full load only up to 40 degrees Celsius.

The Leadex V P130X comes in two colors, black and white. We got the latter, which looks nice! The unit is certified as Platinum by 80 Plus and Cybenetics and has a Standard+ noise rating. Its cables are modular, and the FDB fan doesn't spin at light loads for lower noise output. You can turn off the semi-passive operation if you want through a switch located at the unit's front side.

There are more than enough cables and connectors, including two EPS and eight PCIe, along with twelve SATA and four 4-pin Molex connectors. All cables are long enough, and the distance between the peripheral connectors is ideal. Finally, there are no in-cable caps. One major flaw here is that they used thin, 20AWG gauges for the second PCIe connectors, so you should avoid using them in power-hungry graphics cards.

The PCB is tiny, yet it is not overpopulated with parts since Super Flower uses several vertical boards for various circuits. The design is clean, without any wires running through the board, and there is room for a pair of bulk caps. Build quality is good. Super Flower used good parts everywhere and soldering quality is high.

The transient/EMI filter has all required parts to do a good job. There is also an MOV for protection against voltage surges, and an NTC thermistor and relay combo suppress high inrush currents.

A single bridge rectifier is used, and it is cooled down by two heat sinks.

The APFC converter uses three Infineon FETs and a single CREE boost diode. There is also an SPN5003 FET used to cut-off the APFC converter when the PSU is in standby, to reduce energy consumption.

Six Infineon FETs regulate the 12V rail. The minor rails are generated through a pair of VRMs, using in total eight FETs and two PWM controllers.

Lots of polymer caps are installed on the modular board, along with seven electrolytic caps which belong to Chemi-Con's mainstream KRG line. In this stage the stress is not high, though, so there won't be any issues with the specific electrolytic caps.

The resonant controller also plays the role of the supervisor IC. It is also supported by an LM324ADG operational amplifier.
