Today we have the SilverStone Strider ST85F. What may be the third installment in the Strider Trilogy (ST60F, ST75F and now the ST85F.) What makes the unit a “Strider” is that it’s modular and is OEM Enhance.
SilverStone lists important specifications on the side of the box. Here we can see that the paint wont kill you if you eat it when it flakes off. There is a minimum noise level rating, but no maximum noise level rating. At least we’re guaranteed that the power supply will AT LEAST be 20dBA.

The power supply is 180MM deep, which makes it deeper than most lower power unit, but a decent size for an 850W with a modular interface.
We have our useless MTBF at 25°C and we’re told that operating temperature is 0 to 40°C. Wow! Only 40°C?
What “rails” we have are also listed on this side of the box. You can see here that unlike previous Strider models which had four +12V rails, the ST85F only has two, but at 35A each, they are very high capacity.
The +12V1 goes to the main ATX connector, the peripheral Molex connectors, half of the 8-pin EPS12V connector and one of the PCI-e interfaces. The +12V2 goes to SATA, the other half of the 8-pin EPS12V connector, the 4-pin ATX12V connector and the other PCI-e interface.
Here’s a more traditional table layout describing what rails put out what:

|Max Combined Watts||180W||768W||6W||15W|
On the opposite side of the box we have a few shots of the cables with their connectors, the modular interface and some inside shots. I have similar shots farther in the review. I think you’ll like mine better.
Upon opening the box we are greeted by the ST85F manual. Well… we’re not really “greeted” by it. It doesn’t have the ability to talk or sing songs like those singing greeting cards. I just meant I opened the box and it’s the first thing I had… never mind.
This is a first for a Strider… a nylon pouch with a Velcro enclosure for storing unused cables.
Thrown separately in the box is the usual power cord and baggie of mounting screws (I’m sure you can imagine how many of these coarse thread hex head screws I have by now.) They also throw in a couple of the new 8-pin PCI-e connector cables, almost as if their inclusion was last minute. I’m sure it may have been since the newest PCI-SIG specification was finalized just last month.
The SilverStone Strider is kept cool with a giant, 135MM intake fan.
The unit comes in the box with all of the modular cables connected. This is typical of all of the Strider units.
Below is a list of all of the cables and connectors the ST85F comes with…
|SilverStone Strider ST85F 850W – Cabling|

|ATX connector (550MM)||20+4|
|2 x 2 ATX12V connectors (550MM)||1|
|8-pin Xeon/EPS12V connector (550MM)||1|
|6-pin Xeon/AUX connector (550MM)||1|
|2 x 3 PCI-e (550MM + 150MM)||4*|
|2 x 4 PCI-e (550MM + 6-pin @ 150MM)||2|

|SATA Drive power connectors (2 x 500 + 250 + 150MM)||6|
|Fan only connectors (thermostatically controlled 12V only)||0|
The idea of a modular power supply is that you only have to use the cables you actually need. All other cables can remain unplugged from the main unit. This reduces cable clutter and helps improve air flow.
There are some examples with the ST85F that seem to miss this point. Have a look at the 6-pin PCI-e connector cables above. Each cable splits into two connectors. This is fine if you have a pair of 8800GTX’s, but if I had a pair of 8800GTS’s, would I use one cable with two connectors? For the sake of less resistance, I would rather have two one to one 6-pin cables. Sure, I could use both cables, but then each cable would have an extra connector that would need to be hidden away.
Take, for example, the SATA connector in the above photo. There is one wire harness that runs power to up to six SATA drives. So if you have only one or two SATA drives, you still have four to five connectors you need to hide away.
Finally, have a look at the 8-pin PCI-e connector cables. So the power supply can power a pair of 300W PCI-e cards, they put both an 8-pin and 6-pin on the same cable. Again, to reduce resistance, I would want to run a separate 6-pin and a separate 8-pin if I had only one card… which I can do… but then I have this extra four inches of cable to hide.
