With new cards just on the horizon, you will need evermore powerful PSU’s to run them. SilverStone is no new kid on the block. You can trust them for a reliable PSU such as the Element 850w.
As graphics cards keep on getting more powerful, they also require more power. It was not that long ago when a 400 watt PSU would run the latest high end hardware without breaking a sweat, now times are a bit different. Idealy you want at least a 500 watt powersupply, and more around 850 watts if you are running a high end system. SilverStone has introduced another PSU that falls right in this high end bracket, the Element 850watt PSU.
This PSU features a class leading dual 12v rails equating to a total of 62A. This much power will ensure that your brand new high end video card will have all the power it needs and then some. A high degree of efficiency also comes with this high power output. This means that you will not be wasteing lots of electricity on essentialy nothing, and instead be useing it to power your components, and drive down your electricity bill. Lets dig deeper into this SilverStone PSU.

PICTURES & IMPRESSIONS
As with any box, there is some valuable information to sift through. On the front you can see the 80 Plus Bronze sticker, which means this PSU meets the requirements to be certified, which includes over 80% efficiency. The front contains SilverStone’s blab about all of the most important features of the PSU, while the side includes the same information in multiple languages. The other side of the PSU box (not shown) includes a list of all of the cables included with the PSU.
The inside of the package is simple, but gets the job done. Two pieces of foam keep the PSU locked in place and insure that it is not freely moving around, endangering the structural integrity of the PSU. All the cables are nicely routed, so you don’t have a bunch of cables sprawled out all over the box. Neatly placed on the top is the power cord, and manuals (not pictured).
The PSU itself comes with the bare minimum of accessories, a bit disappointing for a 850 watt PSU. What they do include will get you up and running. This includes a power cable, a couple manuals which will show you just how to work the PSU, and its warranty. There are also thumb screws for the PSU, but many cases already come with PSU screws, so these most likely wont be needed. There are also Velcro strips included, but I don’t really know what these are for, and the manual does not include any information about what they could be used for.
Here is a picture of all of the included cables. These include one 20+4 motherboard connector, one 4+4 CPU power connector, two floppy connectors, six SATA connectors, six Molex connectors, two 6-pin PCIE connectors, and two 6+2 connectors. This is plenty enough connectors to run just about any computer, even a computer with SLI GTX295’s.
Here we have the real thing delivering the power to the computer. As you can see the outside has a nice black coat of paint on it. Many cases are black, so this should fit in perfectly with the majority of them. One disappointing thing about this PSU is that it is not modular. This will turn off a lot of people, but modular PSU’s tend to cost more, so many people would rather save the money and deal with the cables. Moving on to the fan you will see that it is a 140mm, which should keep this PSU quite cool, and SilverStone added the nice touch of putting their name and logo on the center of the fan.
As we pop the side off of the PSU we get a better look at the guts. The PSU looks of pretty good construction, and the heat sinks are plenty large enough, so you can be rest assured it won’t be overheating unless you throw it in an oven.

For the tests I used 3DMark Vantage to achieve a game like experience, which should lead to the maximum load possible. For the idle tests I manually turned the PSU on with nothing attached to it. A Kill-A-Watt watt meter was used to measure the wattage being drawn by the computer from the wall socket. A Craftsman digital multimeter was used to measure the voltages on the connector to ensure that the most accurate result was obtained. To get the Power Factor Correction, I had to run the PSU with the minimal components, since it will not give this with nothing plugged in.
The current ATX 2.2 specifications allow for the following variation in voltage outputs:
- 3.3 Volt Rail: 3.135 – 3.465V
- 5 Volt Rail: 4.75V – 5.25V
- 12 Volt Rail: 11.4V – 12.6V

|OutPut Power||Idle||Load||OutPut Power||Idle||Load||OutPut Power||Idle||Load|
|12 volt||12.07||12.03||12 volt||12.19||12.17||12 volt||12.19||12.16|
|5 volt||5.12||5.11||5 volt||5.14||5.15||5 volt||5.14||5.16|
|3.33 volt||3.33||3.325||3.33 volt||3.412||3.14||3.33 volt||3.41||3.38|
As you can see, the SilverStone PSU had higher voltages, but the Corsair PSU still had no issue staying in ATX 2.2 guidelines. The Power Factor Correction was much better on the Corsair PSU. Overall, the SilverStone is a worthy PSU that is of great quality.
One component that can never be forgotten is the power supply. This component will most likely last you through multiple computers, so you don’t want one that will give out on you after a long gaming marathon. When you pick up a SilverStone PSU, you can be sure it wont quit on you after just a year of using it. You can also expect it to be very power efficient. Over time this will save you a lot on your power bill, maybe even enough to pay for itself, because the PSU is a Bronze 80+ PSU. This means that the PSU is more than 80% efficient at load.
Another factor to consider is power. You don’t want to be underfeeding all of your components, which is why the 850 watts on this PSU will keep you well above the recomended wattage. While I was testing the system, it never went above 405 watts, which leads me to believe that it will easily be able to handle SLI GTX275, for some serious gaming power. The only real problem with this PSU is it’s not modular. This will not bother a lot of people, as non-modular PSU’s are cheaper, but many of us don’t like the extra bundle of cables that come with a non-modular PSU. Whatever your needs may be, the SilverStone Element 850w will rise up to the task, giving you plenty of power and delivering great efficiency.
