Price Per the Watt:

Power Supply Memonex MOD EX 600W at $47.00* = $0.08/Watt (03-2010)

* Current selling price in China. (Power supply not available in the USA or Europe).

The Memonex MOD EX 600W power supply performed very well and certainly exceeded expectations, but I would not refer to it as "high end". The DC voltage load regulation was actually quite good and it easily supplied the full 600W of DC power with noise/ripple levels that met the requirements of the ATX12V V2.2 specification. The power supply packaging carries an 80 Plus logo, or at least a pretty good representation of it, but the power supply just doesn't meet with 73% efficiency at full load on 110VAC, which is a long way from the required 80%. It certainly isn't certified, according to the 80 Plus Org website, and going of its performance, it just wouldn't make the grade. The arrangement of the modular cable connectors is, to say the least, unconventional with any modular cable plugging into any of the four available six-way modular cable sockets. This means all the rails, 3V3, 5V0 and 12V have to be available on all four of the power supply six-way modular cable sockets. This being the case, the 3V3 and 5V0 rails take two of the six available positions leaving only two each for the 0V (ground) and +12V rails, which are expected to supply the single PCI-E modular cable with one 6-pin and one 6+2 pin connector. It's possible to connect up a single high end graphics card or, as the accompanying literature states, dual graphics card crossfire or SLI systems.  The power supply is certainly capable of powering the card(s), but are the four pins of the modular cable socket, that worst case could be supplying - via a single modular cable - fourteen pins at the graphics card (s), capable enough? It's pretty obvious here that the modular cable socket could be overloaded.

The Memonex MOD EX 600W power supply performed quite well, but the arrangement of the modular cables and power supply sockets is flawed and, for this reason alone, it shouldn't be used with a single high end graphics card or dual card configurations. The inclusion of only two SATA power connectors will severely limit its usefulness, especially in the enthusiast market, two just isn't enough! The electrical performance of the Memonex MOD EX 600W was quite good, but it has poor efficiency at full load.  It's certainly capable of powering an internet or office PC with a single PCI-E connected mid range graphics card, but for anything requiring more power, especially on the PCI-E front, the Memonex isn't recommended.

 

Pros:

  • Good DC voltage load regulation
  • Great power factor levels

 

Cons:

  • Lack of SATA connectors
  • Poor efficiency at full load
  • Unconventional modular cable connections that could overload
  • Poor packaging and accessories bundle
