Conclusion:

Environmental Factors:

Foam inserts are once again used to protect the power supply. The Antec Truepower Quattro 1000W does however maintain power factor levels well above 0.9, and in combination with a maximum efficiency of 88%, it pulls a few green points back. No silly bag for the modular cables either!

 

Price Per Watt:

Antec Truepower Quattro 1000W at $184.99 = $0.18/Watt (10-2009)

 

The Antec Truepower Quattro 1000W performed very well during testing, but I have a couple of issues with its construction I would just like to point out. DC voltage load regulation was excellent, efficiency just about reaching the levels required by 80 Plus certification and noise/ripple, although a little on the high side, was still within the ATX12V V2.2 specification. What did concern me is a lack of modular cables and the way they are configured. I noticed during testing that two of the pins on the sockets for the two 6-pin PCI-E modular cables are connected to the 3V3 and 5V0 rails, making them unavailable for PCI-E use.

 

The photograph above shows the 6-pin PCI-E modular cable power supply connector. The two unused pins carry a 3V3 and 5V0 rail connection on the power supply socket, making them unusable for PCI-E 12V power, which resulted in two wires being crimped into one socket to give the necessary three yellow and three black wires at the graphics card end. Could it cause overload problems at these points on the more power hungry graphic cards, probably not, but I thought it worth pointing out.

The Antec Truepower Quattro 1000W lacks modular cable connections in my opinion. It will easily power two high end graphics cards in SLI or Crossfire, but that's as far you go with the four available PCI-E connectors (two 6+2-pin and two 6-pin). Power consumption of a high end dual graphic card computer would be 600-700W maximum, which leaves 300-400W of unusable power. That's fine for the user who likes a little headroom, but it does prevent the use of this power supply with three high end graphics cards – rare I know, but they are out there, and the Antec Truepower Quattro 1000W could power such a configuration with more connectors.

All in all, the Antec Truepower Quattro 1000W is a very capable power supply that will easily power any dual graphics card configuration. The paint job may not be to everyone's taste, but I can see the appeal it may hold for some, especially the car enthuiast. Ripple levels on the rails are a little higher than most other power supplies in this class, but are still within the boundaries set by the ATX12V V2.2 specification and won't prove to be a problem. Fan noise, especially at high loads, could be unacceptable for some users, but it is to be expected with the use of a small 80mm cooling fan hitting nearly 3000 rpm.

 

Pros:

  • Excellent DC voltage load regulation
  • High efficiency
  • 5 year warranty
  • Build quality

 

Cons:

  • Lack of modular connectors
  • Fan noise at high loads
