Thermaltake Toughpower DPS 850 W Review

The box features a photo of the PSU at its face, and we find the series description in relatively small font right next to it—the word "digital" in very small font as though Thermaltake meant to keep it a secret. They should really advertise this PSU's digital control all over the package with distinctive fonts instead. The front-bottom of the box is covered in a series of badges describing the seven year warranty, the ErP Lot 6 and 80 Plus Gold compliance, its digital control, and support for Intel's new Haswell processors.

Thermaltake lists the most important features of the unit in multiple languages. Whether these really are the unit's most important features is debatable.

This side hosts the same description as the other side, but in different languages.

The rear has several photos of the unit's internals and externals, and a screenshot of the digital controlling/monitoring software. Thermaltake also lists all available connectors and the PSU's output specifications here.


Packing foam completely surrounds the PSU inside the box, protecting it incredibly well. The PSU is also wrapped in a slick, black cloth bag with Thermaltake's logo on it. A luxurious note, which, however, many users will appreciate given the product's high price.

The bundle includes a storage pouch for all modular cables, a warranty leaflet, a user's manual, some zip ties, a set of fixing bolts, an AC power cord, and two anti-vibration pads in case your chassis doesn't include any.

As you can see, the amount of provided cables is large enough and the PCIe cables distinguish themselves from the others through their red connectors.


The unit looks great and the same applies to its finish. Thermaltake did a nice job here. The DPS-850 easily stands out from other PSUs thanks to its golden fan grill and rounded corners. The red line wrapping itself around its enclosure looks pretty nice, too, though it makes the dismantling process a little bit harder. The specifications label is on the rear of the PSU, which nicely avoids messing with the view should you install the unit into a windowed chassis.

The fully modular panel doesn't feature many connectors since the PCIe cables have two connectors each, and there is only one EPS connector. Thermaltake thankfully used a normal mini-USB connector instead of the proprietary one Corsair uses in their digital PSUs.

The unit is pretty large, but its design and the fan-grill design make its size pass by unnoticed. Also, any contemporary ATX case will be able to accommodate the DPS-850 without, so you don't have to worry about its slightly increased length.

All cables are flat and "almost" ribboned. As you will notice, the 24-pin ATX cable consists of several ribboned cables, which makes it more flexible but doesn't help its looks, and its get-up may even slow cable-management down since the user will have to spend more time arranging it inside the case.

The PCIe cables have red connectors, which make them stand out from the rest.

The peripheral cables are flexible enough, which will make cable management easier, while the USB cable is pretty long to avoid compatibility problems with mostly older cases that have their PSU bay in the top.
