Inside the Tuniq Ripper 1000W:

As I grounded myself and prepared to pull the cover off of this PSU, I discovered that there weren't any "Warranty Void if Removed" stickers on the case or covering the screws.  This is the now the third PSU I've pulled apart that didn't have such a sticker - the previous two were also Tuniq PSUs.  Even though there wasn't a sticker warning about electric shock, I still made a mental note not to discharge any large capacitors with my fingers.  Once the case was opened I got a good look at the main layout of the PSU.

The PSU specs state the Ripper is cooled by a 14cm fan, but according to my ruler and the fan model number, it's only a 13.5cm fan - the same fan that is in the Tuniq Potency 750W unit.  Once again, we'll round up to the closest whole number and give them the missing 5mm.  Regardless, the fan is large enough to keep the components cool.  The heatsinks are lean - virtually identical to the 750W unit, but seem to be well designed and take advantage of the large fan.  They cover a good percentage of the choke coils and seem to make good contact with the voltage regulators.  The components inside look a bit lean for a 1kW watt unit and it will be interesting to see how it holds up in a few minutes.

You may have noticed above that the fan has a bit of a plastic shield over about 20% of the active cooling area.  This is to provide a bit of an airflow pattern inside the PSU and to protect some of the wires for getting too close to the impeller blades.  You may also notice that this PSU is almost identical internally to the 750W Tuniq Potency we reviewed a while ago over here.

 

Test Setup & Info:

In the past, we've prided ourselves on real-world testing.  For graphics cards, CPUs and memory, what matters is what takes place in real applications and games.  We also held that philosophy for PSU testing, but after a while, we realized that there is more to a PSU that being able to run a machine stable over a few weeks or months.  In reality, if there is a lot of ripple, this can damage sensitive traces on your $700 graphics card or $1300 CPU.  A multi-meter alone is not good enough to check PSU voltage stability.  It's for this reason that we've updated our PSU testbed, and will continue to improve the detail and quality of our PSU reviews.  That being said, we will still be testing the PSU in a system and will be including stress tests from real components in the real world.

We have purchased a Tektronix TDS2002 60MHz Dual Channel scope and it has already become invaluable around the shop here at BCCHardware headquarters.  I've used it to troubleshoot everything from PSU's to Radars, and we are using it today to check the stability of the Tuniq Ripper 1000W PSU on the next page.
