Tuniq Ripper 1000W Power Supply
While Tuniq is not a very well known name in the PSU market, many of you modders out there are very aware of Tuniq's sister company, Sunbeamtech. Tuniq is a subsidiary and looking to move into the very lucrative market space of high power computer power supplies. So, do the Tuniq have what it takes at 1000 watts?
Build Quality
As we already know from Tuniq’s packaging the Ripper 1000 watts features a single fan design. The Ripper 1000W’s single 140mm fan is in the same vein as the preferred standard of a single 120mm fan. The 140mm fan is obviously larger and used for quiet cooling due to its ability to move a larger volume of air at lower RPM than a smaller diameter fan. This is the largest fan we have ever seen in a power supply and SuperFlower was one of the first manufacturers to begin using this design, but recently companies such as CWT have begun to as well. Additionally, given the size constraints of the ATX12v form factor a 140mm fan is most likely the largest size fan that can fit in a standard width ATX power supply. The 140mm fan should give excellent cooling and be very quiet so long as it is paired with a good fan controller. At the same time, the key criteria in our evaluation is whether or not the cooling solution is sufficient, not necessary its sound level or form factor.
External Build Quality
The exterior of the Tuniq Ripper 1000W is finished in a flat smooth black finish that is very basic but functional. The top of the unit is dominated by the single large 140mm fan while the rest of the unit is fairly barren as the unit has APFC so the rear is clear and the fixed wires all exit from a single point on the front of the housing.
The Tuniq Ripper 1000W comes in at a total length of ~6 1/4 inches while the cables all reach out to ~18 inches to the first or only connector. As we stated above you can see here that black sleeving does not reach all the way back into the units housing but rather stops short by about 1 1/2 inches.
Internal Build Quality
Once we remove the four screws securing the units housing and open it we see a power supply that looks vaguely like the OCZ ModXStream Pro 700w, yet with some distinct differences that we will discuss below. On the similar side though, we see that once more there are Rong Chyuan transformers used here. As we said previously, these are normally not seen very often outside of Enermax built units but given the fact that we have seen them twice now outside of Enermax units makes it seem that Rong Chyuan may be branching out. Also as we have said before, this is not necessarily good nor bad, just interesting as these are less common parts than the in-house parts of CWT, Seasonic and other brands or more common third party companies like CLICK. On the topology side the layout of this unit is fairly typical for a single 12v transformer independently regulated unit as opposed to some of the newer DC-DC designs on the market. While not the newest topology going this design type is still very good and appropriate in the high end. The heatsinks in this unit are aluminum and are shaped in order to maximize surface area in an overhead fan configuration. The fan paired with these heatsinks is a Tuniq branded fan that I could not find listed separately at the time of writing.
On the primary side we see that the heatsink that contains the APFC components along with the bridge rectifier has a section cut out to accommodate the primary filtering capacitor. This capacitor is another "Rec" capacitor from TREC and is rated at 470uF 400v 85c just like we saw with the ModXStream Pro 700w. The APFC coil is situated towards the "front" of the unit behind this capacitor at the rear of frame.
As we move over to the secondary we again see the three coils indicating that this unit is an independently regulated unit as opposed to the group regulated design we saw in the ModXStream Pro 700w. However, like that OCZ unit we find the secondary is also filled with "Rec" labeled TREC capacitors. Lastly, we find that the fan controller, and OCP circuitry are located on the add in PCB here while the wiring is all bundled and routed to the right of frame then through a plastic wire guard.
Build Quality Summary
The Tuniq Ripper 1000W presents us with an interesting mix in regards to its build quality. Externally, the unit is dressed in a very basic flat black with all of its cables well and almost fully sleeved which gives us a very functional, if basic looking unit. Moving to the interior we see a generally well constructed unit that has at least good integration and topology. However, the unit is stocked with "Rec" branded TREC capacitors which is really a shot in the dark and could be, or maybe should be, replaced with higher quality components if this unit is to be marketed as a quality 1000 watt unit as opposed to a budget 1000 watt unit. All in all, this Sirfa unit looks very much like the ModXStream Pro in general build quality and component selection which previously let us down a bit. However, this unit varies in significant design elements so let's move on and see how this unit fares in the load testing portion of our review before bemoaning these points any further.
