Overview

The SilverStone DA1650 packaging is interesting in that it is smaller than I was expecting for a 1650W unit. Oh, and it is blue. The front of the package is devoid of information save for the 80 Plus Gold seal (when we check the 80 Plus website, we do not currently find the unit listed) and some ETA/LAMBDA seals. The rear of the packaging gives us most of the information we usually find as we see a fan noise graph, efficiency graph, the power label (reproduced below), and the connector count (reproduced below). It also mentions that the color is Black (lead-free) and the unit does indeed taste like unleaded. The side of the package has some advertising including “FDB fan”, “All Japanese capacitors”, “Full modular”, etc. Lastly, the DA1650 carries a relatively short 3-year warranty.

One odd bit we find is that the packaging lists 3% voltage regulation. This is odd because the SilverStone website lists 2%. This is probably a copy-paste kind of error of some sort. For us, it does not matter so much as the load testing later will tell us what the numbers really are, and if they are under 2% then who cares. If not……then we might have questions.

The DA1650 is advertised as being a single 12v rail power supply with a capacity up to 137.5A (or ~100% of the unit’s capacity) if necessary. The minor rails (5v and 3.3v) have a capacity of 25A each and the combined capacity of those two rails is 130W. Combined with these outputs, we find that this unit has 12 PCIe connectors, 16 SATA connectors, and 6 Molex connectors.

Once we open the SilverStone DA1650 packaging we find the power supply, mounting screws, modular cables, the power cord, and the user manuals. The user manuals are different from previous examples as they are very short. Instead, you are supposed to scan a QR code to get the full versions. Sigh. Let’s move on to the unit itself now.
