InWin IP-P450DJ2-0 (450W)

This model from InWin differs from the previous one not only with its wattage but also with a letter in the model name.

There’s little difference externally. The PSU is assembled in the same housing as the IP-P350GJ2-0 except that the fan grid is now flush with the top panel and cannot become a problem when you are installing the PSU into your system case.

The internal design resembles the AQ series models discussed above. The DJ series is almost an exact copy of them.

The main difference between the AQ and DJ series is the size of the heatsinks which are smaller in the DJ unit and made from bars with molded “fingers” at the top. This doesn’t tell anything about the quality of cooling, though. Larger heatsinks sometimes provide worse cooling as they create an additional aerodynamic resistance to the air flow.

Perhaps you’ve already spotted the trick. The +12V rail is known to be the most important one for a modern PC. The 350W IP-P350GJ2-0 model had a load capacity of 300W on this rail. And the 450W IP-P450DJ2-0 turns out to have exactly the same load capacity of that rail. As a result, the effective load capacity of these two PSUs (in other words, the amount of power a modern PC can get from them considering the typical load distribution among the different power rails) is identical.

The PSU is equipped with the following cables and connectors:

  • Mainboard cable with a 20+4 connector (41cm)
  • CPU cable with a 4-pin connector (34cm)
  • One cable with two Molex connectors and one floppy drive mini-plug on each (27+15+15cm)
  • One cable with three Molex connectors (45+14+14cm)
  • One cable with two SATA power connectors and two Molex connectors on each (44+15+10+15cm)

Alas, we’ve got the same thing here. The PSU has a lot of Molex connectors for PATA drives but does a modern PC need that many? The user is just going to use adapters on most of those Molexes.
