Antec TruePower Quattro 1200W Conclusion

With the TruePower Quattro 1200W, Antec can’t reach the highest efficiency ever and some buyers probably won’t like the cable configuration with many fixed cables like the two peripheral harnesses. It lacks the sort of cable management many like, because there is no space for a bigger connector panel.

However, Antec delivers one of the best results for temperatures with a delta (t) of not more than 8° and a nice voltage regulation with a clean output. At 10% load +5V shows exactly 5.00V and doesn’t drop too much with more amps on it. +12V is also nice. Only +3.3V could be regulated better with a result of -3.64% at 110% load. Power Factor was amazing and reached more than 0.99 even at 230VAC. 88.67% efficiency is the result at 50% load and 120VAC, which is slightly worse than the Seasonic X-series from our previous test but not enough that we'd really worry.

The ripple and noise results are nice too. There is not more than 30-35 mV on each rail and all measurements are well within the ATX specification. If you buy this PSU, however, you should stay below 80% load, because the fan gets really loud after that. Otherwise the TruePower Quattro is very silent below 50% load and if you play games or listen to music, noise should not be a problem. Considering the sort of components you'll need to reach 80% load (960W output), you'd probably already have plenty of noise coming from your PC anyway.

The internal design is dominated by two very large heatsinks and Japanese capacitors from Nippon Chemi-Con and Sanyo. Antec is using many shrink tubes as well as foils for short circuit protection and has a good Silicon Touch IC with many safety functions. The EMI filtering is well equipped with an additional MOV behind the entrance. There is not much space for cooling in the secondary circuit but the ventilation is strong enough to solve this problem.

Eight PCIe connectors are more than enough for a triple-SLI setup as well as many peripheral connectors for up to 20 hard drives. All the cables are very long, like the main cable at 65cm. So this PSU is designed for full size towers, a common choice for high-end computer systems with multiple GPUs.

Pricing is actually quite reasonable for this sort of PSU. The standard model starts at $215 online. If you want to buy the OC model you have to pay much more and it is only a solution for extreme overclocking. We couldn't find any in stock, but it looks like prices will be north of $335. For those that need a beastly 1200W PSU, we can say that the Antec TruePower Quattro 1200W is a good choice and sets a high quality standard. If you can live with the limited cable management and you're planning to run a tri-SLI or dual HD 5970 cards, this should work just fine.

    Very silent? Isn't that like a little bit pregnant?

    haha yea pretty much

    My 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

    Inexpensive 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.

    SPCR 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.

    into 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.

    Why?

    Why would you be loading it to 110%?
  • michal1980 - Thursday, July 8, 2010 - link

    ok, 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.

    But 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.

    Ha,here in UK we have 240v Yay us :) 3000w at our disposal.
