Packaging and Appearance

Since we have a cable management with the Decathlon we found a bag in the box which can be used to store cables that aren't needed at the moment. It also comes with the standard power cord and screws in the box. The DA650 is much longer than the OP650. The reason for this will be easy to see once we open the PSU up. The whole backside has been punched with small hex-shape holes for ventilation purposes.

On the side are two white stickers informing owners that the warranty will be voided if they're broken. We have taken the liberty of voiding our warranty so you don't have to. Behind the one sticker is a potentiometer and the other one covers a little switch. According to Silverstone the switch is there to combine the four 12V rails into one. Meaning that with that switch they just turn off the OCP for each rail and (hopefully) have a bigger OCP (Over Current Protection) circuit kick in.

    Perhaps my expectations are messed up, but I have yet to be impressed by any of the units reviewed thus far. Then again, when spending $150 to $200 for a PSU, I am going to set my sights very high. Reply

    They used 3 x Primary caps, which is more expensive than 1 450uF, but since they are in parallel, the ESR reduces significantly. Although this may have a minimum bearing on the proceedings (secondary side is more important), there is less stress on the PWM/switching transistors.

    I think you may have issues calibrating your setup, given that every single PSU you have reviewed seems to have larger than usual voltage drops.

    Given this, and that the rails do not seem to be solid/heatsink is too small, I think the PC power and cooling PSU is still the better buy.

    Besides that PC Power and Cooling is a well respected PSU OEM, why even bother with something else in the same price range.

    Who makes this PSU anyhow ? I know it is silverstone branded, but I am fairly certain they did not make it.
