    PSU Question

    I have an ATI 4870 1gb, Intel Quad Core Q6600,2 drives- one a burner,and like 4 USB slots usually
    in use. Would a 500w PSu be enough for this rig?

    Re: PSU Question

    it will be if you don't overclock. But no real options to expand, I would say 650/700 to be future proof.

    Re: PSU Question

    Really? Because I just realized that the PSU i had that died only did so after i started messing around with overclock =/. So I should just leave it at default or lower? Or was my PSU really just faulty?
    It worked for like 2-3 days.(Getting it replaced)
    Thnx

    Re: PSU Question

    I'd say probably a dodgy PSU - what brand was it? A decent 500w PSu would be more than enough for that system. Check these threads: http://forums.hexus.net/hexus-hardwa...-readings.html http://forums.hexus.net/hexus-hardwa...r-results.html

    Re: PSU Question

    ur pc couldn't possibly draw more than 350w on the HIGHEST overclock. see this:

    Re: PSU Question

    Ok, one last question. Does overclocking or increasing fan speed to like 90% really reduce the life of the gpu or fan?

    Re: PSU Question

    Increasing the speed f the fan will increase the wear in the bearings - but not to the extent you would really notice.

    If you need to increase the supply voltage to the CPU or GPU to get it to overclock successfully, then you are placing it under greater electrical stress than it was designed for and therefore there is an increased risk of premature failure. However that risk is difficult to quantify, and is probably only measurable statistically across a large sample of overclocked/over voltage components.

    Re: PSU Question

    yes, increasing the fan speed will reduce the life of the fan as this will cause an extra strain on the bearings. overclocking components 'should' reduce the life of the component but as long as the temps are kept in check and you don't over-volt it then it shouldn't have much of an effect.

    beaten to it by perterb... if that is your real name.

    Re: PSU Question

    however, if you go for a 650-800W psu you have headroom for expansion (should you wish to)

    Re: PSU Question

    I got the replacement and it worked for about 2 months and then it gave out AGAIN.
    Does this company suck or what?
    THIS is what I bought

    Oh and by the way, my PC originally came with a 350 Watt PSU.

    Do you think I should take a shot at using the default one?

    It's cheap for a reason, I wouldn't trust that to run my PC for 5 minutes...

    Re: PSU Question

    TBH, a Corsair HX450W should be able to power the whole shebang IMHO:

    http://www.newegg.com/Product/Produc...CORSAIR%20450W

    To the OP the PSU you bought is crap especially since you have got high power consumption components like a Q6600 and an HD4870!!

    This PSU will also do the job:

    http://www.newegg.com/Product/Produc...82E16817341016

    OCZ are a decent make but are relatively affordable.

    Re: PSU Question

    If it's a good quality 350w PSU then it should be fine but if not then I'd consider upgrading to something better - what make/model is it?

    Re: PSU Question

    I personally think that a OCZ ModXStream Pro 500w is great for only around 40 USD after the rebate!!
