Sugestões para fonte de alimentação

Discussão em 'Dúvidas e Suporte Técnico PC' iniciada por phhs80, 10 de Setembro de 2008. (Respostas: 15; Visualizações: 675)

  1. Boa tarde,

    A ventoinha da fonte de alimentação do meu computador, por vezes não liga, tendo eu que desligar o computador e tornar a ligar para conseguir que ela comece a funcionar. Além disso, o barulho que produz é elevado em algumas alturas. Penso que chegou a hora de a substituir.

    Neste contexto, gostaria de vos pedir ajuda nos seguintes tópicos:

    1. Que fonte de alimentação me sugerem, que seja silenciosa e barata?

    2. O meu computador é um Intel "dual core" com 2Gb de RAM, leitor de DVDs, 2 discos duros (500Gb e 160Gb, respectivamente); estaria apropriada uma fonte de alimentação de 600 watts?

    Antecipadamente grato,

    Paulo

  4. Agradeço a sua resposta.

    Sim, tenciono fazer "upgrades" futuros.

    Não sei exactamente que placa gráfica tenho. Como poderei determinar isso?

  5. Agradeço a sua resposta.

    É um bocadinho carota, a que fonte de alimentação que sugere, mas se tiver de ser...

    Já que estão numa de fontes, qual será melhor a LC Power 600w Silent 2.2 ou a Lc Power 550W Green Power?
    Qual terá mais potência?

    Obrigado pelas respostas!

    E sim e uma 6500!!! Tens toda a razao!!!!
     
  15. Obrigado por todas as respostas.

    De facto, a minha placa gráfica é uma XFX GeForce 6500 (rev a1). Como poderei eu determinar a potência mínima que a minha placa precisa?

    E já agora, que potência precisa em média um disco duro?

    Paulo

    Compra a NOX que te referi ou esta LC-POWER 550W SUPER SILENT V2 (LC6550). Não arranjas nada aceitável que seja mais barato, penso eu.
