SilverStone's power supplies are typically quite subtle and understated in appearance, and the Strider Titanium ST80F-TI 800W is no exception. The latest Titanium revision in the Strider lineup has a depth of only 15.0cm, and is one of the shortest power supplies we have reviewed here in APH Networks. The SilverStone Strider Titanium ST80F-TI 800W is the smallest fully modular Titanium certified 800W power supply on the market today, and looking at its sheer size -- or lack thereof -- is impressive to say the least. Power supplies like the Strider Platinum ST75F-PT is shorter, but the ST80F-TI is a product of a higher efficiency certification grade. Most modular power supplies are longer than non-modular units by a centimeter or two, as the extra length is needed to accommodate its connector board at the back. We will take a look inside the PSU on the next page. For most ATX or eATX chassis, length should not be much of a problem, if at all. However, if you have a mATX or mITX case that takes standard power supplies, the shorter length will definitely serve as an advantage, especially considering the fact the ST80F-TI is fully modular.

From our view above, SilverStone's logo is located dead center on the five-ring fan grille, which itself is a little offset to the side. The full branding is embossed onto the metal casing at forty five degree angle on the other side. Its classical SECC construction comes finished off with something a little more unique this time; a volcano rock style, textured black finish for a more interesting look. On the side is series of stickers that contains the unit's serial number, internal quality test certifications, and revision number. Residing behind the five-ring fan grille -- where quite a bit of its center opening is lost to the company's logo -- is the primary and only cooling fan installed. The 120mm fan generates airflow by drawing air from the bottom of the power supply over its internal components to keep the temperatures in check. Exhaust heat is allowed to leave at the back of the power supply through the large secondary honeycomb mesh opening. Meanwhile, four screws secure the power supply case together; where one screw has a warranty seal over it, so you cannot open the Strider Titanium ST80F-TI without voiding the five year warranty.

Starting from the back part of the power supply, we have the same familiar honeycomb mesh design like most PSUs with bottom mounted fans; the only thing you will find here is a horizontally aligned male connector for power input on the western edge. It comes with no on/off switch at all. The low resistance honeycomb mesh design is implemented to maximize airflow and minimize air resistance. This is done as heat needs to leave the power supply as easily and efficiently as possible, because the Strider Titanium ST80F-TI 800W incorporates only one 120mm fan at the bottom, with no auxiliary fans. It is also implemented in a very efficient manner, as the power input connector took up a minimal amount of room at the back. As with most new power supplies, the SilverStone Strider Titanium has an automatic full range (100V-240V) AC line voltage selection, so the user does not have to worry about manually selecting input voltage.

Like many SilverStone Strider power supplies, such as the Strider Gold S ST85F-GS 850W and Strider Platinum ST75F-PT 750W, the Strider Titanium ST80F-TI 800W is a fully modular power supply. This means all cables are completely detachable from the main unit. While it is somewhat questionable with regards to why this is necessary for other manufacturers, since cables such as the ATX 24-pin and ATX 4-pin/EPS 8-pin have practically an 100% chance of being connected at all times, SilverStone actually has a case to argue for this design choice. If you have a tight fitting case, you can opt for the optional PP05-E short cable kit for better airflow and better cabling jobs. Additionally, with fully detachable cables, it may prove to be beneficial to an extent when building your computer initially.

The rear cable connection panel is done nicely. Similar connectors are grouped together; and are laid out in a very logical manner. To ensure you know what is going on, a diagram is situated below for minimal ambiguity. From the top to bottom and left to right, we have four PCI Express outputs for four 6+2 pin connectors, two ATX/EPS 4+4 pin outputs, four peripheral outputs for twelve SATA/three Molex/one floppy, one ATX 24-pin connector block, as well as one 4-pin Vsense socket. All of them except for the ATX 24-pin and Vsense sockets have plastic caps over them from the factory for a better look. Incompatible outputs will not physically fit into each other, so I think SilverStone has done a great job in this regard. This generous array of available connectors should be more than sufficient for casual users and power enthusiasts alike.

The external build quality of SilverStone's Strider Titanium power supply is excellent as always -- a good indication the company is serious about the product they are selling. We will take it apart in just a moment. Fit is done well with minimal panel gaps, and all edges are nicely finished off. The level of refinement with regards to the external build quality is comparable with all the other high quality PSUs I have used in the past. As aforementioned, we will crack open the power supply to see what components are inside in the following section.

The voltage specification label on the right panel of the SilverStone Strider Titanium ST80F-TI 800W. There are two main virtual rails. Up to 22A can be delivered via the +3.3V rail for a total of 72.6W; while the 22A on the +5V rail brings the output to 110W in this area. The total combined output for the +3.3V and +5V rail is 120W. In other words, your power allocation combination must fall within the limits of the listed specifications. Meanwhile, a single powerful +12V rail delivers up to 66A (792W) to reduce operating overhead compared to multiple +12V rails. Overall, the combined power output for the whole ST80F-TI is... well, 800W haha. Again, your power distribution in your system must fall within the limits provided -- it must not exceed 72.6W on the +3.3V rail, 110W on the +5V rail and 120W combined for both, 792W on the +12V rail, and 800W combined between the +12V and +3.3/+5V rails. It does sound a bit confusing to understand how this works at first, but generally speaking, this configuration allows fairly flexible power demands and should be sufficient to accommodate most users. The overall distribution is quite reasonable for an 800W power supply.

The SilverStone Strider Titanium ST80F-TI 800W is 80 PLUS Titanium certified, which means that it is certified to be at least 90%, 92%, 94%, 90% efficient at 10%, 20%, 50%, and 100% load, respectively. There is no higher certification for 115V internal non-redundant power supplies at press time.

A total of eight modular cables are included out of the box. All modular cables are flat and easy to bend, making them extremely easy to work with. 16 AWG wires are found on the ATX 24-pin, ATX/EPS 4+4-pin, and PCIe 6+2 pin bundles. Everything else is 18 AWG, which is standard, and to be expected.

The following modular cables are included out of the box:

- 1x ATX 20+4 pin, 55.0cm
- 1x ATX/EPS 4+4 pin, 75.0cm
- 1x ATX/EPS 4+4 pin, 55.0cm
- 4x PCIe 6+2 pin, 55.0cm
- 3x SATA, 4 connectors each, 60.0cm to first connector, 15.0cm spacing thereafter
- 1x Molex, 3 connectors, 60.0cm to first connector, 15.0cm spacing thereafter

A 10cm long Molex to Floppy adapter is included for those who find it useful. These are specified measurements from the manufacturer. Most users should have no problems with SilverStone's Strider Titanium ST80F-TI 800W, even if your case has a bottom power supply mount. 50cm is the general standard, and this power supply met or exceeded this recommendation in all counts.
