Antec Signature 650 Power Supply Review

Hardware Secrets
21 November 2008
  • Summary: This is a great power supply. It can not only deliver its labeled power at 50° C, but you will be able to pull up to 870 W from it. Efficiency is one of the highlights from this product, achieving 84.5% efficiency at full load. With loads between 40% and 80% (between 260 W and 520 W) you will see efficiency between 85.6% and 86.4%. Only under light load (20%, i.e., 130 W) efficiency was "low", at 82.3%. Voltage stability and noise and ripple levels were outstanding.

Antec Signature 650W

3 November 2008
  • Excerpt: Ever since I put the finishing touches on my SG-850 review, wherein I handed out my first ever "10" for performance, something has been eating away at me. I couldn't help but wonder if the extraordinary performance of that unit had been a mere fluke. So, when Antec offered me the chance at the 650W model of the Signature lineup to compare with, I just had to say yes.

Antec Signature 650W Power Supply

1 October 2008
  • Conclusion: We thought the 850W version of the Antec Signature series was very good, so we wanted to see if the smaller model could deliver a similar performance. We weren't disappointed with what we saw today. This kind of topology of course only works with an 80mm fan at the back or the front of the PSU, and Antec made a good choice in including a PWM-controlled fan.

  • Conclusion: It’s easy to say the Antec Signature 650W is a very impressive power supply. It entails rock stable rails, impressive efficiency and easily the quietest cooling solution we’ve yet experienced. As well as being a good performer, it looks fab and certainly is a quality piece of tech. It’s a shame about the price, but this unit is built to last so would be a good investment. I am therefore pleased to award it 4/5.

Teste da Fonte de Alimentação Antec Signature 650

Clube do Hardware
12 February 2008
  • Conclusion: Esta é uma fonte impecável. O único ponto negativo que podemos ver é realmente o seu preço, especialmente aqui no Brasil por conta do enfadonho “Custo Brasil”. Ela é claramente voltada aos usuários quem querem "o melhor". Ela merece o nosso selo de Produto Recomendado, mas o usuário "esperto" deve procurar por uma fonte com melhor relação custo/benefício.
