Efficiency and Power Factor

The PSU has a good efficiency which is higher than 88% at loads of 300W through 600W and only lowers to 86% at full load. The power factor good, too. It is about 0.99 in about half the diagram.

+5Vsb Source

The standby source of the Signature PSU is rated for a current up to 3A. Its voltage is only 0.1V below the rated value even at full load, which is perfectly acceptable.

Summary

The Antec Signature leaves a very nice impression with its excellent quality of manufacture, splendid electrical parameters, sufficient selection of cables and connectors, and with such a quiet operation at low loads that could hardly be expected from a PSU with only one 80mm fan. No wonder that Antec considers the Signature series the best of its product range even though the company offers PSUs with higher wattage ratings.

Perhaps the only downside of this PSU is its high price. But you won’t be disappointed if you pay it.
