Super Flower Zillion 650W PSU is a solid choice for budget-conscious PC builders who prioritize reliability and efficiency. Its DC-DC design, high-quality components, and quiet operation make it a suitable power supply for a wide range of systems, from gaming PCs to home workstations.

One of the standout features of the Zillion 650W is its DC-DC power supply design. This design ensures stable voltage output and reduces ripple noise, leading to improved system stability and performance. Additionally, the use of high-quality 105°C Japanese capacitors enhances the PSU’s durability and lifespan.

The Zillion 650W comes with a 120mm fluid dynamic bearing (FDB) fan, which provides quiet operation and efficient cooling. The fan’s speed is automatically adjusted based on the system’s load, further contributing to a peaceful computing environment.

In terms of connectivity, the Zillion 650W offers a sufficient number of connectors to power modern PC systems. It includes a 24-pin ATX connector, an 8-pin EPS12V connector for the CPU, and multiple PCI-Express connectors for graphics cards. The cable management is also well-designed, with flat black cables that help to keep the system tidy.

Super Flower, the company behind the Zillion 650W, is a renowned manufacturer of high-quality power supplies. Established in 1990, Super Flower has a strong reputation for producing reliable and efficient PSUs. The company’s commitment to quality and innovation has earned it a loyal following among PC enthusiasts and professionals alike.

PSU Internals:

Opening the PSU first prominent detail we look at is the blue colored PCB with superflower’s monogram and PCB rev detail. The PSU is packed up with all the modern ATX requirements including X and Y input side filtering, Active PFC, a dual 10A GBU-1008 Rectifier, TEAPO DG Long Life Series Main Capacitor with 3000Hrs @ 105°C specification, A DC-to-DC module for 5V and 3.3V power ouput. At a keen glance, we see that the PSU comes with in-rush Current Protection particularly dubbed as primary side Over-Current Protection, MOV based surge protection and an Active PFC Circuit embedded onto the PCB. The Wiring is of neat-black ribbon 16AWG which complies with Intel ATX standard.

PSU Load Testing:

Our basic ATX paramters quality testing includes verification of Voltage Regulation of 12V, 5V and 3.3V rails and if they fall within ATX standard limits under standard loading conditions upto 100% of rated load. We will also verify the ripply noise present in each rail across various loads as well as verify the Input & Output power for the sake of efficiency and whether the PSU qualifies for the 230V 80+ Power standard while staying within the specified power factor limits. SuperFlower Zillion 650W comes certified with 80+ Bronze Certification which means it should fall within or borderline qualify for the redundant (continuous running operation) limits of 85% efficiency at 20% load, 88% at 50% load and 85% at 100% load with efficiency calculated between input VAC Power and output VDC Power.

Regulation & Noise:

To qualify under ATX v2.2 as well as multi-rail ATX v3.1 standards, the Power Supply must have maximum of 5% acceptable deviation from rated voltages of the 12V, 5V and 3.3V rails and under any circumstance within 100% loading conditions this deviation must not exceed. While the ripple noise innately present in each VDC output must not exceed 120mV peak-peak on 12V Rail, 50mV peak-peak on 5V Rail as well as 3.3V Rail, and 50mV peak-peak on 5Vsb as well as 120mV peak-peak on -12V Rail, this measurement is to be done with an oscilloscope capped at 20MHz bandwidth low-pass filter set at acceptably larger time scale to view all possible fluctuations within the signal. Increasing resolution of the time-scale will only bring up the smaller amplitude of the peak-peak ripple while completely hindering the major ripple it is riding upon. The Ripple noise on the VDC rails here is a combination of various frequencies and amplitude overriding over each other to form a complex waveform. This ripple is unique to every PSU design and can be identifiesd as characteristic waveform.

Operational Temperatures:

Monitoring the temperatures is crucial in our testing and it includes monitoring rectifier temperature as well as main capacitor temperature. During the load testing these two components take major beating. Then comes the Primary VRM side FETs and moving towards the secondary side.

Our Procedure:

Our testing includes these 3 main paramters i-e. 80+ Efficiency qualification, VDC output regulation as well as the output ripple without any shady business with the oscilloscope. We have mounted a PT1000 temperature sensor with calibrated display directly on primary capacitor surface as well as on the rectifier. Since there are two rectifiers working in parallel, one rectifier will have identical thermal behavior as the other. With our fixed DC power load tester we have tested SuperFlower Zillion 650W at various load conditions upto 110% of the overload condition as per ATX minimum standard. Please note that the ambient temperature is 17°C and our temperature measurements are also in °C.

Results:

Applying the loads, we found SuperFlower Zillion 650W to be performing well within the ATX standard limits as well as qualifying for the 80+ Bronze Standard. Our observations are tabulated below:
