  1. raidmax isn't known for their quality

    like 5/10 or worse?

    According to the supplied link I would need about 440watts, so unless raidmax is utter junk, I ought to be good for now yes? I just need it to last 3-4 months
  3. 5/10 bout, but dont push it too hard for 3-4 months
  4. most cheap power supplies go up in smoke with a sustained load as low as 60-70%

    Hate to see your whole new system in the trash can for cheaping out on the power supply.

    IF you are spending 600+ dollars just go get the 80$ power supply too.

    As obsidian86 already pointed out, Raidmax is not known for quality power supplies. Luckily, your current pc configuration does not require a lot of power, just don't push it to the limit.

    For the future, the general rule of thumb is a high quality 500 to 550 watt power supply with sufficient current (amps) on the 12 volt rail(s) can easily power a system with any single video card made. A high quality 700 to 750 watt power supply with sufficient current (amps) on the 12 volt rail(s) can power a system with two video cards operating in dual mode. There are a few exceptions like the new ATI Radeon HD 4770, 5850, and 5870 cards which use a little less power due to their energy efficiency.

    Corsair, PC Power & Cooling, and Seasonsic are some of the brands that have a reputation for high quality power supplies that consistently earn high marks in technical reviews. They are reliable, stable, and come with a 5 year warranty. Lately we've been seeing a few other brands offering some high quality units.
