NorthQ Giant Reactor 1kw ATX PSU

Looking Inside

Looking Inside

Being surprised by the rather standard size of the Giant Reactor in comparison with some other 1kw+ units on the market, I was anxious to see what was inside. Normally the quality of a power supply can be determined by the size and weight of the components inside the PSU, however, recent power supplies from manufacturers like FSP and Seasonic have proven this thoery to be wrong.

NorthQ Giant Reactor Inside

After reviewing just under 30 power supplies for Overclock3D, I'd like to think that I can recognise most units by looking at their insides. This was certainly true when I opened the Giant Reactor only to find that the entire layout of the PSU was very similar to a unit i'd tested in the not so distant past....

NorthQ Giant Reactor 1000w

As you can see from above, the NorthQ Giant Reactor is based on exactly the same internal components as the Silverstone Strider 850w ST85F (minus the Striders modular connector backplane). This was further confirmed when I retrieved the Strider 850w from storage and compared both units side-by-side, finding no differences in the components used.

This then begs the question: If both of these units use the same internal components, how is it possible for one to be rated at 850w and the other 1000w?

NorthQ Giant Reactor Fan

The Giant Reactor also makes use of the same 135mm brushless fan as used in Silverstone's ST85F. Unfortunately I was unable to find any specifications for this fan, however NorthQ state that it runs at over 25dBA when the unit is at 1000w load.

"1000w is a lot of power to squeeze into a standard ATX PSU casing, but somehow NorthQ - a relatively unheard of company, claim to have managed it. Today we take a look at their "Giant Reactor" PSU to see if it can deliver the goods."
