Antec Signature 2200W PSU Review (2025)

We got an early sample of this power supply from Antec HQ, and the box artwork was not finished when it shipped. The box weighs around 4.5kg. Yes, it's a hefty unit.

A couple of days after receiving our test sample Antec did send us the image above of the new packaging the customer can expect to see. Very nice and very ‘Seasonic PRIME like' which makes sense, as they are the OEM partner. It is good to see Antec putting a lot of effort into highlight the superior Cybenetics certifications as well on the box artwork.

The cables are all high quality and individually sleeved, offering reassuring quality for a power supply at this hefty asking price. Cables are all between 16-18AWG. The 12+4 Pin PCIe (600w) cables are 16-24AWG, and there are two of them.

As you would expect with a flagship 2200 watt power supply there are no shortage of power cables to cover every eventuality.
