ABS / Tagan BZ900 900W Power Supply Review

Exterior Impressions


Upon first glance there isn’t much to distinguish the BZ900 from the rest of the products in the already-crowded 850W-950W performance segment but there is quite a bit more to this unit than a plain black exterior. More and more manufacturers are moving away from the 120mm fans of yesteryear and have begun equipping their power supplies with larger, more efficient 135mm and 140mm fans. The ABS / Tagan partnership did not buck this recent trend and equipped this power supply with a clear 135mm fan complete with blue LEDs.

We have long been complaining about the liberal application of finishes that scratch too easy on some of today’s power supplies. Luckily, Tagan decided to go with a nearly scratch-proof powder coating for the BZ900 and we can’t help but applaud their decision.


Aside from the perforated metal grille, the back of the BZ900 holds a “Turbo” switch that is supposed to switch the +12V rails from the “Normal” multiple rail mode to one single +12V rail. Unfortunately, we have no way to test out if this actually works so for now we will have to take Tagan’s word for its usefulness (or lack thereof).

We also see that the power switch is protected with a clear rubber tab much like we saw with the 2-Force II. This makes it a bit harder to move but it also prevents it from being moved by an accidental bump in the wrong area.


The crowning jewel on the exterior of the BZ900 is the modular interface since each type of connector is color-coded and has a plastic ring around it which glows a different color. The effect is absolutely stunning in a Christmas-tree sort of way but people who like their case interiors without unnecessary “bling” need not apply. As you can see in the picture above, the modular interface only lights up when there is a cable installed.
