Thortech Thunderbolt 1000W Modular Power Supply Unit Review

The Thunderbolt series comes in four different wattages ranging from 650W to 1200W, I will be taking a look at the 1000W unit. Looking at the power table, we can see that the unit outputs a total of 1000W through its 12V rails which means that the unit is capable of providing all of it’s power to the all-important components such as graphics cards and CPUs when required. All the PSUs in the series use a quad-rail design apart from the 650W version which uses a duel-rail design. This ensures that none of the 12V rails on any unit exceeds 30A which lowers manufacturing costs and makes the unit more reliable; however it does require some basic knowledge from the user to be able to balance the rails.

The cables included will not be an issue whatsoever! There are enough connectors for a quad-SLI setup with 12 hard drives, a little excessive for a 1000W if you ask me! And they have clearly thought about the connectors- it uses two EPS connectors, one being 8-pin, the other 4+4, reducing unnecessary connectors. The braid is also really good and you can’t see through it. My only gripe is that you can’t clip the split connectors (like 20+4-pin) together, which makes inserting them annoying. It also means that the extra 4-pin part of the 20+4-pin connector isn’t actually held on by any clips.
