Antec Signature SG-850
Although there are PSUs with higher wattage ratings in Antec’s product line-up, it is the Signature models that are officially positioned as the top of the range. The manufacturer promises stability, high wattage, silence and highest efficiency because the Signature PSUs comply with the 80 Plus Bronze standard (i.e. they are 82% or more efficient at loads of 20% through 100%).
The actual maker of the PSU is Delta Electronics.
Packaging and Accessories
The product box has an original design, being made from thick black cardboard with a bright yellow band in the middle. There are golden letters “Antec” on the top panel while the side panel has a barely visible pressed-out text that reads “Signature 850 watt power supply”. There is no other information on the box.
Besides the PSU, the box contains an installation guide, a set of detachable cables, a power cord, and four screws.
The PSU case is painted a black matte paint and has a length of 180 millimeters. The golden letters “Antec” are not painted – it is a separate plate glued into the depression in the top panel.
There are four connectors on the back panel: two for graphics cards and two for peripherals. The +12V line the connector is attached to is marked nearby.
