Packaging

The box is tiny, as it is the power supply inside it. At the front there is an angled photo of the product with the model number highlighted in large white fonts near the bottom-right corner. There “Platinum” word is missing so you will have to look for the 80 PLUS Platinum badge to distinguish the older Gold model from this one.

On this side the most interesting part is the sticker with the model and serial numbers. The same sticker depicts the production country which is China, as usual.

A graphical list of the provided connectors is at the top of the box, while on one of the sides the major features of the product are provided in three languages.

 

Two graphs showing the efficiency and fan speed/noise can be found at the back, along with the power specifications table and a scheme showing the dimensions of the product.

Contents

The protection at the internals of the box is adequate, since foam spacers surround the product.

The cloth pouch looks nice and the bundle is rich including a case badge, four fixing bolts, several zip ties, an SFX-to-ATX adapter along with all paper work. The USB flash drive is only for us, reviewers, containing a full evaluation report of the sample, which was created with the help of a fully automatic Chroma station.

Exterior

At the front we find the honeycomb-style exhaust grille along with the AC receptacle and a small power switch.

One of the sides hosts the power specifications table which also depicts the product's serial number, while on the opposite side is a sticker showing the model number and Corsair's logo.

The modular PCB hosts seven sockets, three for the EPS and PCIe cables, two for peripheral and SATA and another pair for the ATX cable.

 

The external design is not fancy, but we won't mind about this from the moment the SF450 delivers good performance. In power supplies everything has to do with performance and efficiency with looks, RGB lighting and other similar features being at the bottom of our list.
