External Look
It’s a non-modular PSU with pre-installed cables following the Intel Form Factor of ATX 12V V 2.31. Its dimensions are 150 x 140 x 86mm, with an input voltage range of 200-240Vac and an input frequency range of 47-63 Hz. The unit features basic protection against OVP, OPP, OTP, and SCP and operates at an efficiency of 85% at a typical load. The top side includes a 120mm fan, a warranty void label on one of the screws, and a fan filter for cooling.
On the side, a charcoal-colored sticker with Cooler Master’s logo and the MWE 500 model is present. The power info label and serial number label are also on this side. The model MPW-5002-ACABW unit is a switching power supply with Active Power PFC, 200-240V AC input, and a single +12V rail with 38A. The rear side features a mesh for heat dissipation, a 3-pin per connector, a power on/off button, and no vents on the backside.
The backside has a solid cover without vents, and 5 screws indicate the PCB is secured to the base. The unit includes 24-pin ATX and 8-pin EPS power cables sleeved in black, while other cables are not sleeved or braided.
\The connectors’ info is as follows:
| Connector | Quantity | Length of the Cable |
| MB 20+4 Pin | 1x | 550mm |
| CPU 12V 4+4 Pin | 1x | 550mm |
| PCIe 6+2 Pin | 2x [On a single cable] | 500mm |
| SATA | 6x [3x on single cable] | 700mm |
| Peripheral 4 Pin | 3x [On single cable] | 850mm |
| FDD Cable 4 Pin | 1x [On the Molex connectors’ cable] | – |
Internal Look
It is time to take a closer look at the PCB and circuit design. Examine the PCB and circuit design of the computer, ensuring stable voltages like +5V, -5V, +12V, -12V, and 3.3V are available at power supply terminals. Consider voltage, current, harmonic factor, cross-load regulation, noise resilience, and safety parameters like overvoltage protection (OVP) and overcurrent protection (OCP) for optimized power provision.
The external view reveals a metal body with color-coded cables. Removing the lid exposes a black PCB with components working together. The power socket features a safety-certified capacitor for protection against EMI/RFI interference, ensuring reliability and quality power components.
Inspecting the lateral section, observe a bridge rectifier and a 400V capacitor for AC ripple filtering. Active power factor correction distinguishes this power supply from entry-level ones, improving the power factor affected by high switching operations. The secondary stage provides stabilized, rectified, and filtered DC voltage, with proper isolation, solder joints, and traces contributing to a high-grade PCB.
Considering all parameters, the Cooler Master power supply qualifies as an entry-level budget option with an additional active PFC feature, setting it apart from its counterparts. It offers a reliable system choice that meets criteria like safety, robustness, and quality power components.
Testing
We don’t have the right tools to measure the PSU’s performance accurately. So, we used Thermaltake Dr. Power II to test it. This device checks voltages on different connectors and identifies any issues with the PSU. We compare the results with Intel’s standards and the testing equipment’s measuring range.
The below-mentioned table has the Intel Standard, Measuring Range, and Reported Voltages:
All the tested voltages fall within Intel’s standards. Here are the connectors-wise reported voltages:
| Connector | Reported Voltage (V) |
| ATX 24-Pin | 11.6 |
| CPU 4+4 Pin +12V | +11.9 |
| PCIe 6/8 Pin +12V | +11.8 |
| Peripheral | +5.01, 3.3V |
| SATA | +5.01, 3.3V |
