Packaging

The box features some fancy graphics design with a power supply glowing at the front.

Right below the power supply photo we find a number of icons including the 80 PLUS Platinum badge, the series description along with the unit's wattage and three more icons describing the ten-year warranty, the compatibility with the newest Intel CPU sleep states and the support for systems strong enough to allow for VR gaming.

At the sides of the box are the efficiency and fan noise curves, along with the power specifications table and a list of the provided cables and connectors. The power cord type is also shown. Our sample shipped with a US-type cord.

There is an interesting photo at the back of the box, showing the unit's internals. FSP provides a description of the platform's major features and there is a long feature list as well – mentioning some interesting information about the supply.

Another feature of this product is that it comes with changeable side stickers, since in the bundle FSP includes two spare sets.

Contents

The protection inside the box is good, with packing foam totally surrounding the product – this is also wrapped in plastic.

A smaller box contains all cables along with the power cord. The bundle includes the user's manual, a warranty leaflet, two sets of stickers and a set of fixing bolts.

Exterior

The unit's exhaust doesn't utilize the usual honeycomb design, but the perforations are much larger enhancing the airflow. The small on/off switch is located right next to the AC receptacle.

On the sides the stickers depict the line's name, while a large sticker at the bottom side shows the power specifications table along with the product's serial and part numbers.

There is a void warranty sticker however FTC (Federal Trade Commission) looks to have a problem with those. Nonetheless, the truth is that it is very dangerous to open a PSU especially if you are not trained in such repairs.

At the rear the modular panel has nine sockets and the sticker covers two more perforations. Apparently the same modular panel cover with the HPT750M is used, to save money and keep the production cost low.

The unit's dimensions are quite large given its 650W capacity. FSP used the same chassis with the HPT750M since it would be expensive to build a new one just for the HPT650M.
