The Seasonic Focus GX-750 ATX 3.0 PSU comes in a large yellow and black colored package with a list of features on the front along with "10 Years Warranty" and "80-Plus Gold" labels.
The back side also offers a list of features which we have detailed above. The primary focus in on highlighting the efficiency of this PSU.
Opening the package reveals the PSU itself, along with a pouch that includes all the cables connectors, and manuals.
The PSU itself is packaged inside a cloth which is secured between two pieces of foam.
This is a 140mm chassis which makes it really small and easier to manage within crammed-up PC cases. The exact dimensions of the PSU are 140x150x86mm.
Keeping the design simple, we get the power-in plug and the power on/off switch at the back. The large exhaust vents are also here to push hot air out of the PSU chassis.
Now depending on how you use the PSU, the bottom panel reads the specifications and power ratings. The PSU is rated to output a maximum of 70.8A and 850W through the 12V rails.
The sides of the PSU have the XPG Core Reactor II labels.
Coming to the connectors, there are 1 PCIe 12+4 (12VHPWR), four PCI-e 6+2-pin connectors, an ATX 24-pin (14+10 pin) connector, and four 6-pin peripheral connectors.
