A Detailed Look – The PSU (Cont’d)

 

Koolance 1200W Liquid Cooled Power Supply Review - Cases and Cooling  37

 

All of the cables on the Koolance 1,200W power supply are modular.  The black anodized front panel incorporates 12 plug-in connectors for attaching whatever combination of cables best suites your application.  The connectors are physically differentiated so you can’t mistakenly plug a cable into the wrong connector.  The four blue connectors are for the PCI-E cables, which are 6-pin.  Noticably missing are any of the new 8-pin PCI-E connectors.  With this much power, I would expect to see at least four 6-pin and two 8-pin PCI-E connectors provided.

All of the modular cables are neatly sleeved in black mesh plastic.

 

An Inside Look

 

Inside the Koolance 1,200W liquid cooled power supply we find a platform we have seen before.  The main power supply circuit board and components appear identical to the Channel Well Tech built unit we saw a few months ago in Thermaltake’s Toughpower 850W PSU, which by the way proved to be an excellent power supply.

Note that even the original heatsinks have been retained.  The key difference is the cooling system.  Where as the Toughpower 850W PSU used traditional air cooling, the new Koolance 1,200W PSU uses submersive liquid cooling.

Now this brings up an interesting question: Is the new Koolance liquid cooled PSU really an 850W unit in a 1,200W shell?  I believe the answer to this is NO.  Just because the Toughpower 850W and the Koolance 1,200W power supplies share the same basic platform doesn’t mean they are the same or should be rated the same.  The cooling systems are dramatically different and that’s the key.  The main limitation for most electronic devices is heat dissipation.  A components rating is typically based on how well it can be cooled.  A 10 ohm resistor may be labeled as either a 5W part or a 10W part depending on how well its packaging can dissipate heat.  As our testing will soon show, the Koolance liquid cooled power supply is truly a 1,200W PSU
