450W

Is my 450W power supply sufficient to support a Q6600 and a Overclocked HD 4850? I'm not sure it is, so if someone could comfirm, that'd be nice.

More about 450w
  1. what brand and model of PSU is it?
  2. Yes, we need to know the brand and model. If it is a quality brand like Corsair, probably. If it is a generic unit that came with your case, probably not.
  3. Yeah, it came with the case, What wattage should I have to support my system?
  4. amps on the (+)12v line is usually more important for a GPU. what amps does yours have?
  5. + manufacturer of case??
  6. Double post.

    Depends on the power supply. A 450 watt Corsair probably would. A 450 watt Antec might. A 450 watt generic probably wouldn't.

    The current rating of the 12 volt output is critical.
  7. EDIT: Turns out it's only a 400W, I was told it was 450W.
    Here's a pic, cos I don't know much about power supplies.
  8. looks like a FSP psu (from what i gathered from the code.) They have an excellent reputation and the 12v amps don't look to bad either. They're used in the Dell gaming boxes if i remember correctly
  9. FSP is a decent brand. Only 400W though, with 27A on the combined +12V rails...I'm not sure that's quite enough, not for overclocking those parts.
    Making arbitrary assumptions about your system, I got 363W using a NON-overclocked 4850. Stock, it needs 9A, so overclocking probably adds 1A-2A to that, or 12W-24W. It looks like technically that PSU could handle it, but you'd be running on the edge, which is asking for trouble. I don't think I'd do it.
