Silverstone's Decathalon series PSUs are designed to deliver maximum power simply and efficiently. Instead of bumping up cost and complexity by using multiple +12V rails, the DA850 has 1 extremely robust 70A rail. The Active PFC and >80% efficiency rating ensure that no power is wasted.
The power connectors are fully modular. This lets you use only the connections you need. Any extra cables can go back into a handy carry bag, so you can find them when you upgrade. The cables are all sheathed to de-clutter the inside of the case, enhancing airflow.
There is a 120mm fan on the bottom of the PSU to move maasive amounts of air to keep everything cool. The back panel is a honeycomb mesh broken only by a switch and the power plug for virtually unrestricted airflow. Go ahead; build the system of your dreams, the DA850 can handle it.

Self-Destruct Enabled
- Pros: Visually nice design, very long cables, many useful connections, modular cabling, near silent operation.
- Cons: “Detonated” within 3 minutes of [otherwise] normal use. Literally. 'Sounded like 10 to 20 gunshots coming from inside the PS -- made my ears ring. After the smoke cleared (again, literally) a post-mortem exam revealed nothing. No visible scorching anywhere outside of unit. My only guess would be compromised connections internally to the 120 VAC receptacle. ‘Could have been arcing of line voltage. Bottom line: Silverstone clearly does “not” test every unit they ship.
- Other Thoughts: This unit replaced a noisy 645W Ablecom unit in a dual-Opteron workstation. We were extremely fortunate the Silverstone’s self-destruction did not damage the system. Our advice? Any consumer electronic device can fail out-of-the box so use caution, and always keep a Class C fire extinguisher handy.
DA850 - questionable
- Pros: Build quality appeared to be good, and the wires are long and useable in my Cosmos Coolermaster case.
- Cons: Concerned about the PCI-E cables sharing two plugs on one cable... and actually fried one of the plugs on the power supply end, caused Sentinel errors for powering my two MSI 8800gtx HD OC's. RMA'ed, said there is a new revision 3.0 that is supposed to be better, we shall see. Mine was rev 2.5.
- Other Thoughts: Next time I will go with another brand for sure. I'm not happy with this power supply.

Fantastic PSU
- Pros: My first modular PSU, just love this aspect. Powers 6 internal SATA 3.5 HDDS, 2 optical drives, Geforce GTX 260, Audigy 2 sound card, Asus socket 939 mobo all & 4 big case fans all flawlessly. Silverstone has further established itself with me as a great company to trust. PSU's huge fan on bottom now blowing instead of sucking through the unit is a very positive change from traditional PSUs. Also, retail box is VERY sturdy, perfect for storing old PSU and all unused power cables.
- Cons: Wish there were plugs to prevent dust from accumulating in unused sockets.
- Other Thoughts: I turned to Silverstone by default for a PSU since I got my Mach 5 system from Falcon-Northwest in 2005. If they use Silverstone for all cases and power supplies, then I assumed I should make my upgrade PSU from same brand, and haven't been disappointed at all in 2 months I've been running with this unit.
Great on paper, not so much in actual use
- Pros: 850W on a single 12+V rail makes it easy to stay within spec while utilizing as much of the capacity as possible. The abundance of modular cables is something I've enjoyed with SilverStone's power supplies, and the addition of two 2x4 pin PCI-E support is great. I much prefer fully modular units vs those that make the motherboard cables permanently attached, if only for asthetic reasons.
It also comes with a rolling bag to hold loose cables which is very useful to prevent loss. The AC cable seems longer than others I've used which I appreciate. The fan is nice and quiet but doesn't work so well in keeping my HDDs directly below cool.
- Cons: Though modular, the way in which the cables are split up could be better. For example, there are a total of 4 PCI-E connectors split evenly over two cables, meaning you'll have to hide a cable for non-SLI systems. Same goes for the SATA connectors, two wires with three connectors each, while the 4-pin molexes have a total of 4 (3 HDD, 1 Floppy). Also, I feel I should mention that the molex cable uses a non-standard connector for the PSU end, with a 2x3 pinout. Luckily the pins are still keyed to prevent the wrong usage.
- Other Thoughts: I mentioned it was good on paper, no so much in use. In my situation, the PSU isn't happy with my APC battery backup. The backup is capable of 865W, this PSU is 850W, but rarely if ever is the backup loaded more than 400W (including monitor and peripherals). Anytime I lose power and the backup kicked in, my PC goes into a pre-POST stage and remains until utility power is restored. This is not useful at all. I'm not sure if it's specifically the PSU or some odd issue with my mobo, but my older 750 SilverStone Strider did not give me any problems like this. I'm thinking the PSU just has no tolerance for power drops but am seriously considering boxing it up for RMA or storage and resorting to a different PSU (like the Strider). I'm hesitant to use another high-wattage SilverStone PSU for a Core i7 build in the future. As an aside, I'd wish companies would try to reduce wattages a bit more. PSUs are going beyond what backups supplies are capable of these days.
Great PSU
- Pros: I have also bought the 1kW ver of this PSU both are great its running my EVGA X58 mobo with 2GTX275s and about 11fans a hard drive and DVD drive and a I7920 @ 4.2GHZ
- Cons: none so far.
- Other Thoughts: none
