Antec TruePower Quattro 1200W

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.
