Antec Truepower Quattro 850W vs Silverstone Decathlon 850W Review

Output Characteristics

Silverstone Decathlon 850W


When looking at the output specifications for the DA850, the first thing that should jump out at you is the absolutely titanic output of the single +12V rail. Considering modern computers take their most of their power from the +12V rail, having nearly 99% of its output available on this crucial rail works in the Decathlon’s favor. I found myself looking at it over and over again: 70A….840W…it's mesmerizing isn’t it?

What else is there? Well, there are other rails, but who cares about them with 70A being waved in front of our faces?


Antec Truepower Quattro 850W


After being smacked over the head by Silverstone’s monster single rail unit, the output specifications of the TPQ 850W seem almost mundane in comparison. Sure, four 18A +12V rails rated at a combined 768W is nothing to turn you nose up at, but it is a good 72W below what the DA850 is able to output. Interestingly, the Quattro can output the exact same +3.3V and +5V amperage as the DA850.

The testing part of this review should prove to be quite interesting because what we have here with Antec’s Quattro is a multi-rail design which is in stark contrast to Silverstone’s single rail design.

While I have no doubt that Antec’s offering can output 850W, it is slightly less versatile than the Decathlon due to the OCPs placed on the rails which limit output to 18A (216W) each. I would have much preferred to see 19A or 20A on each +12V rail of an 850W power supply. On the other hand, I cannot see any combination of components which would contribute to the OCP tripping.
