Corsair HX1050 1050 Watt Power Supply Review

Professional Series power comes to us this time from Corsair in the form of its new HX1050. It is boasting over 1 kilowatt of solidly efficient power for the computer hardware enthusiast with a semi-modular cable system. We will see if this PSU is fit for enthusiasts and if it lives up to its efficiency statement.

Overview

The first thing we are going to look at with the Corsair HX1050 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 of the Corsair HX1050 differs somewhat compared to what we have been seeing recently from Corsair units. Notably, the packaging does not feature the washed out look of the TX or V2 series. It does, however, feature a giant zoomed in picture of the new grill used by the new members of the HX series. The front of the packaging along with this grill has an 80Plus Silver logo, which we find on the 80Plus website as well (finally), and a logo indicating that this unit is covered by a 7 year warranty. This is certainly one of the longer warranties going on enthusiast units currently, and should keep most people through a number of upgrades. Otherwise, the packaging has a number of marketing points, most of which have been recycled from other Corsair units over the years, adorning it. The rear of the packaging has the connector count (reproduced below), power label (reproduced below), a fan speed graph, and an efficiency graph (to go along with the 80Plus logo on the front). These items are all fairly standard fare for Corsair units we have seen and there is nothing really outstanding, good or bad, to see here today.

The power information for the HX1050 varies in a number of ways from what we found with the HX1000W, and not just due to the extra 50W available on this unit. Most prominently, we find that the HX1050 is a single 12v rail unit unlike the dual rail design of the HX1000W. In addition to this, the 12v rail receives a 7.5A bump in capacity resulting in the 87.5A 12v rail being equal to ~100% of this unit\\\\\\'s DC output capacity if necessary. Paired with this 12v output we find the HX1050 has the same connector assortment we found with the HX1000W including 6 modified 8-pin PCI-Express connectors, 12 Molex connectors and 12 SATA connectors. This arrangement is certainly enough for the VAST majority of users and seems well appointed given the market segment this unit is filling and the general specifications the unit carries.

Once we open the packaging of the HX1050 we see the usual assortment of items including the power supply in a pouch, modular cables in a pouch, mounting screws, and user manual. The user manual is shared with the HX750 and HX850 (not HX750W or HX850W). The manual includes the power table, installation instructions, cable lengths, and warranty information. This is once again most of the desirable information in a manual, though there are a lot of more complete ones out there.
