    Re: why a quality psu is worth it?

    Never seen it before, but i like it!

    Ironically enough though, corsair sent me out a replacement cable which DID cause 2 HDDs & my CD drive to dramtically exlpode. Smoke out of the top of an antec 900 brings tear to your eyes!

    (for the record they did replace everything with brand new kit within a week, so kudos to them! )

    Re: why a quality psu is worth it?

    i'm not 100% certain about the methodology - the wording seams weasely to me:

    the quoted wattage on a PSU is meant to be the peak output (not input) power. a 450W supply should be able to push 450W through all combined outputs (this often isn't the case, but that's another story). if a supply is inefficient, then it's normal to pull in more input power than the rated output (i.e. a 450W supply will pull more than 450W of input, if it's less than 100% efficient)

    bad supplies are pretty inefficient, so if you're starving them of input power whilst pulling on the output, then failure is inevitable. BUT (big but) bad supplies can & will explode when you ask them for a "sensible" output, even if you're not clamping a max value on the input, as it seems corsair did here. for an example, check "funnies" at the bottom of http://www.hexus.net/content/item.php?item=1359&page=25 where a "650w" qtec supply draws an increasing amount of power (up to 1100w) trying to push 400w out, before exploding

    so... corsair are right that bad supplies pop, but their methodology is a mean way to trap supplies with <75% efficiency into looking dangerous, when in real-world scenarios the input wattage will never be clamped as in the video

    Re: why a quality psu is worth it?

    corsairs tests are a load of bollox, any componant that relys on a flow of air to keep it cool will go bang with the covers removed preventing airflow

    biggest crock of sh*t ive seen for a long time.

    lets all go seal out pc's in an airtight plastic bag and see how long they last...

    i saw no vid of there psu's under load with no covers ?

    they would go bang like the rest after an amount of time.

    Any half decent PSU will simply shut down when overheating, not blow up. Although having said that, I agree with your point. PSU's have a fan for a reason.

    Re: why a quality psu is worth it?

    pretty evidently not an overheating-related failure. you'd see the same sparks whether in an oven or fridge, all things being equal

    No cover would surely make very little difference, if im not mistaken the 2 black things either side of the silver things (technical, i know ) are fans arnt they?
