Memonex MOD EX 600W Power Supply Review


Closer Look :

The Memonex MOD EX 600W power supply is finished in a very high-gloss, metallic-black paint that shows every fingerprint and scratches very easily.  Care is needed when handling.



















The rear face of the Memonex MOD EX 600W power supply shows the hexagonal-holed exhaust grill that occupies most of the available space for maximum area. The rear face also carries the IEC mains input connector, mains on/off switch, and a blanked off voltage selector switch from back in the days when 230VAC or 110VAC were the only options. The photograph of the front face of the power supply shows the captive cables that are fully sleeved all the way into the exit port and a bank of four modular cable connectors. The connectors are all identical and any modular cable can be plugged into any connector, which means all the rails are present. The obvious disadvantage to this configuration is the modular PCI-E cable that will not have individual connections for the three yellow 12V and three black 0V wires (because the 3V3 and 5V rails have taken two of the six available connectors) and has led to doubling up of wires on the modular cable.



The high gloss finish of the Memonex MOD EX 600W is illustrated by the reflection of a penny on one side of the power supply with the specification label on the opposite face.



The Memonex MOD EX 600W power supply uses a pale gold grill to cover the cooling fan which carries a Memonex logo at its center. Nothing of note to see on the underside, except the printed circuit board mounting points.



The Memonex MOD EX 600W power supply has two captive cables, the 20+4 motherboard and a 4+4 pin ATX12V/EPS12V cable, which are neatly sleeved all the way into the power supply. The modular cable set build quality is good but with only one PCI-E cable carrying a 6 pin and a 6+2 pin connector and only two SATA plugs the choices are a little limited.



Next, the 120mm clear plastic cooling fan is shown.  It is manufactured by Globe, model number B1202512L.  The fan is rated at 12VDC 0.26A and fitted with blue LEDs. The printed circuit board layout is tidy, but there are no visible markings that point to any specific manufacturer.



The mains input filter, so often lacking or non-existent on low end generic units, contains all the necessary components for an effective noise filter. The electrolytic capacitors are all rated at the more welcome 105°C working temperature, apart from the main Capxon capacitor rated at 85°C which is often the case.



The build quality of the Memonex MOD EX 600W is pretty good, but it is let down by poor packaging and a basic set of accessories that doesn't even include any power supply mounting screws or cable ties.  However, how will it perform is really the question to ask!
