XFX Pro Series 450w and 550w Power Supply Review

The box for the XFX Pro 550W power supply is almost identical to the 450W on the previous page. Obviously the output has changed.

Inside there are several power cables, mounting screws and literature on the product.

The same matt finish as the other models in the range, meaning it won’t mark or scuff easily, even after rough handling. The big fan and XFX badge takes centerstage in the middle of the chassis.

The front of the supply is vented for maximum air flow and next to this is a power switch, XFX logo and power connector socket.

The XFX Pro Series 550W can deliver 44A to the +12V output, compared to 34A with the 450W model we looked at on the last page.

Again, there are plenty of cables considering the target audience. The 550W model has 3 more Sata power connectors when compared to the 450W model on the previous page.
