Seasonic X Series 750 W

A Look Inside & Component Analysis »

Packaging


The packaging of the X-750 features a plain design with no fancy graphics, nor any vivid colors. A dark background dominates the front with the Gold efficiency badge and the capacity description occupying the top, right corner. A little below them is a photo of the unit's front side and right next to it resides the series description. The overall design of the box exudes a general air of seriousness.


There is nothing of interest on this side. The opposite side holds the unit's specifications table and a description of available connectors. Seasonic unfortunately only mentions lengths of ATX and EPS cables. They should also include length for PCIe and peripheral cables.


On the right, top corner of this side, we find Nvidia's SLI-ready badge, which isn't important; it simply occupies a spot on most PSU packages. The ErP Lot 6 2013 compliance logo is the real deal. Seasonic apparently doesn't account for old ErP Lot 6 2010 compliance and is eager to mention that their units are compliant with the newer and stricter directive.


On the rear side, we find a lot of useful information about the PSU and its features. Seasonic briefly analyses key aspects of their platform on the back: the patented modular panel that incorporates both VRMs (Voltage Regulation Modules) for the generation of the minor rails, gold-plated, high-current terminals that reduce energy losses, highly reliable 105°C electrolytic caps used in this platform, the existence of polymer ones, etc.

They also mention the hybrid circuit for fan-speed control since it allows for fanless operation at lower loads where noise output reaches the lowest possible level, and there is also a graph showing the fan's speed in both normal and hybrid mode. Finally, Seasonic provides some information on the fan the unit is equipped with. Their favorite San Ace fan may not be so silent at high speed, but it is, without a doubt, of high quality.

Contents


The contents of the box - especially the PSU - are very well protected. The latter is, more specifically, inside a luxurious velvet bag (contrary to the nylon-made one that Corsair uses for the AX760 and their other high-end models) that is surrounded by packing foam. Finally, a large pouch stores all modular cables and the rest of the bundle.


The bundle includes some Velcro straps with Seasonic's logo, several zip ties, a set of fixing bolts, the user's manual, and all necessary cables.

Exterior


The unit's finish is exceptional, although it is not matte enough to provide effective protection against scratches and fingerprints (with the latter being of no concern to regular users - only us reviewers care about fingerprints during the photo-shooting process). The casing utilizes a honeycomb structure to allow for the best possible ventilation and the small on/off switch resides next to the AC receptacle at the front. The specifications label can be found on one of two sides. Some users would prefer it to be on the bottom, but others probably won't mind its current spot. The most interesting part surely is its back with the modular panel. The modular panel features many modular sockets for far too many cables, even for a 750 W PSU. Seasonic doesn't provide enough cables to fill all available sockets since the X 750 has been restricted to four PCIe connectors. You can, however, buy additional PCIe cables to easily increase the number of connectors.

You can toggle between normal and hybrid operation through this switch. The normal operation option will make the fan operate constantly, but hybrid operation mode will only operate the fan as needed during increased loads or high ambient temperatures inside the PSU. This switch should, in our humble opinion, be at the front for easier access once the PSU has been installed.
