Dynex 400 W Power Supply Review

Load Tests

In Figure 15, you can see the power supply label containing all the power specs.

Figure 15: Power supply label.

As you can see this power supply has two virtual +12 V rails. As mentioned before we could clearly see on the printed circuit board that each rail was really connected to the over current protection (OCP) circuit, and each one had its own filtering circuit (own coil and own electrolytic capacitor).
Internally Dynex 400 W (Huntkey Green Star 400 W) is IDENTICAL to Huntkey Green Star 450 W. We are not only talking about the design; we are talking about EVERYTHING. So it seems that the 450 W model is just this 400 W unit with a different sticker! Now we are even more curious to take a look at the Green Star 350 W model – will it be the same power supply as well?
Even though they are the exact same power supply, their labels are different. The 400 W model is labeled with lower limits: 14 A for +12V1, 15 A for +12V2, 28 A for +5 V, 30 A for +3.3 V and 0.3 A for -12 V, against 15 A, 17 A, 35 A, 30 A and 0.5 A, respectively, on the 450 W model.
The +12V2 rail is connected only to the ATX12V cable, so everything else is connected to the +12V1 rail.
Now let’s see if this power supply can really deliver 400 W of power.
