Kingwin Power Force 850W Power Supply Review

While not a "go to" enthusiast brand, Kingwin has produced some excellent computer desktop power supplies over the last five years and these have usually be great values. Does Kingwin continue the trend with its new Power Force 850W model sporting good efficiency, modular cabling, and reasonable pricing.

Overview

The first thing we are going to look at with the Kingwin PF-850 is its packaging, accessories, and documentation. While normally none of these items is a make or break item for a power supply the packaging quite often contains a lot of information about the product we are purchasing. The inclusion of an owner’s manual that provides actual information about our product is also of great help in many situations. Accessories are almost unnecessary with a power supply as the unit is self contained, unless it is modular, but there cases where a manufacturer can include useful accessories to make installation, routing and use more efficient.

The packaging for the Kingwin PF-850 is a good bit different from what we have been seeing from Kingwin units of late and really does start things off with a more mainstream and budget vibe. The front of the packaging does tell us that this unit is supposed to be certified for 80 Plus Bronze and that the unit is covered by a 5 year warranty. A quick check of the 80 Plus website does indeed find this unit listed as being 80 Plus Bronze certified. When we move to the rear of the packaging we don’t find much. Indeed, about all we see is an abbreviated version of the feature list we saw on the website. Making our way around the rest of the packaging we never find anything else of use and really only ever find the list of items that was abbreviated on the back expanded once more. Given what we see there, this is certainly not something I would pick up off a shelf at Microcenter or Fry’s and have any certainty about what it is exactly I was buying.

When we look at the power label for the Kingwin PF-850, we see that it features a single 12v rail with the majority of its capacity able to be provided on the 12v rail. Indeed, this unit has a total possible 12v capacity of 70.83A or ~99% of the unit’s possible DC output if necessary. The minor rails, on the other hand, have a combined total capacity of 150W with each individual rail being capped at 25A each. Coupled with these capacities, we see that the unit has four modified 8 pin PCI-Express connectors, six Molex connectors, and eight SATA connectors. This is considerably less well appointed than we have seen from some other 850W units in the recent past but similar to some older units. Generally though, it has been the higher-end 850W offerings which have had more connector options than what this unit has today.

Once we open the packaging of the PF-850, we see the power supply, the cables in a pouch, mounting screws, user manual, and power cord. The user manual is four pages long in English only. Among those four pages the only useful items we find are some rudimentary installation instructions and the power table. That is about it. That is a very sad effort.
