Antec TruePower Quattro 1200W
Although many users are currently looking for smaller power supplies below 500W, there still is a demand for stronger ones, particularly if you are a gamer with Triple-SLI or Quad-Crossfire systems. Those planning on running NVIDIA's next generation "Fermi" will want a fairly beefy PSU, and the same goes for Folding@Home farms where you'd want a lot of stable power. For the upper end PSUs there are a wide range of models, which doesn’t make the purchase decision easy. In addition, these power supplies are usually expensive so you'll want to get the best features and a reliable power supply that can operate even under maximum load and summer temperatures.
We received a TruePower Quattro 1200W from Antec and as usually we're looking to see if it provides a good overall package. We'll check out the safety features, voltage stability, and the available connectors. Efficiency is also an important issue and affects the energy consumption as well as the internal temperature. We also got a special OC version from Antec. It has two big regulators for the internal fan and +12V voltages. You can easily adjust the rail when the voltage drops down too much. In all other areas the OC version has the same features as the standard model.
The TruePower Quattro 1200W is a PSU that polarizes because of its 80mm fan. Usually a bigger fan also has a bigger cooling area, but lot of it depends on the fan-quality and cooling topology. With a 120-140mm fan mounted on the bottom, you have a curve in the airflow, but with 80mm the airflow is more direct. So temperatures should not be a problem. But will the fan be silent enough for most discerning buyers? Let’s find out!
The product is well packed and includes four screws, the modular connector cables, a short information sheet as well as a power cord.
Six well dimensioned +12V rails with 38A each can deliver the full power of the PSU. Again, we can see a manufacturer using a DC-DC converter. +5V has 30A and +3.3V offers 25A. Together they can handle 170W. The massive standby rail is rated at 6A.

computergeek485 - Wednesday, July 7, 2010 - linkhaha yea pretty much
shin0bi272 - Wednesday, July 7, 2010 - linkMy case has a dual power supply setup... Even running triple or quad SLI I wonder how long it would be before I would need 2 of these. he he he
JarredWalton - Thursday, July 8, 2010 - linkInexpensive Antec PSUs are the same as any other inexpensive PSU: they have to cut some corners. The high-end stuff is generally in a different league.
atmartens - Thursday, July 8, 2010 - linkSPCR gives good power supply reviews. The CP-850 and CP-1000 in particular seem to be high quality. The catch is they only fit several Antec cases. In any case, don't just go by brand name.
michal1980 - Thursday, July 8, 2010 - linkinto a 20amp circuit. Or dont bother having anything else turned on in that room.
1200watts, 110% load = 1320 Watts / 84.04% efficent = 1570.68Watts / 120V = 13 amps. Most outlets really only see ~115 volts. Which puts you at 13.65 amps.
Most room circuits are wired at 15amps. Which means with this psu maxed out you have about 230 Watts left over for everything else.
HOOfan 1 - Thursday, July 8, 2010 - linkWhy would you be loading it to 110%?
michal1980 - Thursday, July 8, 2010 - linkok, at 100% your at nealry 12amps.
Still darn close to the limit of most circuits at home
Simple put, a 15amp circuit can put out 1800watts.
HOOfan 1 - Thursday, July 8, 2010 - linkBut why are you assuming that people would be running the PSU at 110%.
That would be the fault of the owner, not the fault of Antec for building a 1200W PSU.
A triple SLi GTX 480 setup would need about a 1200W PSU, although it wouldn't be pulling that much power.
Not a good idea to even run a PSU at 100% for extended time.
Besides, just put the PSU on its own 15A circuit.
Moricon - Friday, July 9, 2010 - linkHa,here in UK we have 240v Yay us :) 3000w at our disposal.
