Stability

Antec TruePower Quattro 1000W

Out of all the power supplies shown, the Antec Quattro 1000W performs 4th best when comparing its voltage to rated. Furthermore, there is no fluctuation in the voltage which shows this PSU is rock stable.

The 5V rail isn’t quite as impressive. As you can clearly see, the Quattro 1000W performed the worst and is way out in comparison to the other units. The voltages on this rail too do not change.

Fortunately the 12v rail is a little better with it performing 2nd best. There was only a small fluctuation of 0.01v in the wrong direction when changing from idle to load.

Efficiency

PF Standby PF Idle PF Load Watts Standby Watts Idle Watts Load
Signature 650W 16 84 91 7 94 139
Commander 850W 24 77 85 9 98 142

Quattro 1000W 16 86 91 9 104 148
Fatal1ty 700W 20 83 90 9 97 142

From the efficiency tests we can see the Antec TruePower Quattro performed 3rd best in the idle and load test. Its standby result wasn’t too impressive though with it being joint last with the Signature 650W – another Antec power supply.

As for wattage, it performed the worst. It’s using the most power out all seven power supplies. This isn’t a major problem, but it shows the Quattro 1000 watt to lack efficiency.

Noise

Alike the fan on the 850W version of this power supply and like many other Antec power supplies, the Antec TruePower Quattro 1000W is certainly very quiet – not silent however.

Cost

The Antec Quattro 1000W retails for £159 Inc VAT. This is a very competitive price and is only £20 more than the 850W version of this power supply.
