Topower TOP-1000WG 1000W Power Supply Review 01 |


Topower should be a familiar name to many in the PC industry. For years they have produced quality power supplies, cases and more for computer enthusiasts. Several companies have turned to Topower to design and produce power supplies over the years and many often simply rebrand Topower's power supplies as their own. We've seen this twice lately with the Mushkin Enhanced Joule 700W and 800W models as these are simply Topower's Nano Series power supplies with different labels.

Today we are taking a look at the first 80Plus Gold rated power supply from Topower. The Topower TOP-1000WG also happens to be the largest power supply that the company offers in the Nano Series. It promises to deliver up to 1000W of power, features a quad-12V rail design and boasts quite a selection of connectors so that you can make good use of the full 1000W.

Let's start by taking a look at some of the specs and seeing how strong the TOP-1000WG appears on paper.

Specifications, Availability and Pricing

Topower provides plenty of power on the minor rails with both the 3.3V and 5V being rated for 30A each and a combined load of 150W. 12V power is delivered by four individual rails capable of 19A each and a combined load of 76A. It would be nice to see these rails capable of a little more power. Several of today's top of the line GPU's can each pull more than each of these rails provide and some of the rails share loads with other devices. While this should be sufficient for a majority of users out there, a few might find that the individual rails on the TOP-1000WG just aren't strong enough to handle their individual needs.

The TOP-1000WG certainly isn't the most feature rich 1kW unit that we've taken a look at, but it has a majority of the features we check for. Almost the full suite of protections are included with the exception of over temperature protection. Topower decided to natively wire all of the cables for the TOP-1000WG, but they are all sleeved well. Unfortunately the unit is not rated for 100% continuous output at 50C, but the unit does boast an 80Plus Gold efficiency rating.

Topower has excellent market penetration with their power supplies and the TOP-1000WG can be found very easily. Newegg lists the power supply shipped for $171.99. However, some crafty searching will let you grab the 1000W unit for about $161 shipped. Topower warranties the TOP-1000WG for a period of three years. While this isn't quite as long as we would like to see for a modern day power supply, it is certainly better than a one year warranty.
