4. Visual inspection

The Power Man brand is owned by In Win, the Power Supplies from the Power Man line share the same electronic platform as the In Win Green ME line.
The Power Man 650W model has a simple design, the paint is matte and high quality. The Power supply has reduced dimensions, it measures 150mm in width and 170mm in depth with a weight of 2kg.

Despite the compact format used, the interior of the Power Supply is airy, the components are being cooled by two aluminum heat sinks.

5. Testing

The following system was used to test the Power Supply:
–    Processor: Intel i5 4690K @ 3.9 GHz
–    Motherboard: MSI Z97 Gaming 9 ACK
–    RAM: 8GB Crucial Ballistix Tactical
–    GPU: MSI Radeon R9 390X Gaming 8GB
–    SSD: Samsung 840 EVO 120GB
–    HDD: Samsung SpinPoint F3 500GB / WD 1 TB Blue
–    CPU Cooler: SilverStone Tundra TD02 with NoiseBlocker eLoop B12-PS
–    Display: AOC i2769VM
–    Case: Phanteks Enthoo Luxe White

The above system has a power consumption of approximately 500W when in full load, in order to test the efficiency of the Power Supply, the power draw of the system was measured at the wall socket. Also the voltages were measured on the +12v +5v and +3.3v using a multi-meter.
To load the system to its maximum the stability test of the AIDA64 Extreme (5.70.3800) was used with Intel Burn Test V2.
The Power Supply was tested with the system both idle and at maximum load.

For rail voltage tolerance levels, ATX (Power Supply Design Guide) specify that a 5% variable fluctuation is acceptable.

The efficiency of the PowerMan 650W model is good, the total power draw with the system in full load being 581W, thus the Power Supply efficiency is 86% at 77.23% Load from its total capacity. The PSU passes the 80 Plus Bronze certification.

 

The noise level was measured at three different distances from the fans (10cm, 20cm, 30cm.) the noise was measured with a margin of error of ± 5 db.

6. Final thoughts

The first thing that stands out at this Power Supply is the build quality starting from the cables to the interior components. The Power Supply fits the 80 Plus Bronze efficiency standard while the voltage oscillation is within the ATX tolerance levels.
The cables are stiff enough to maintain their shape, but flexible not to impend the assembly process, as a side note; the cables could have been black to create a better look.
In conclusion, the In Win Power Man 650W is a good Power Supply which utilizes quality components starting from the electronics to the fan and cables. At this moment the Power Supply is available in three variants: 550W, 650W and 750W, the last two variants are certified for both Crossfire and SLI use.
The only drawback of this Power Supply is the length of the cables, especially the 8(4+4)pin CPU power cable which at 500mm has an acceptable length but can make the assembly process harder in some computer cases.
