Ok, thought it was at about 70% load.

yea i switched to corsair for my last 4 PSU's and i love them. Have not had a corsair psu die yet had other brands die.
And the corsair units you can find really cheap and are solid performers.
currently have 4 corsair 750 supplies running 3 of them 24/7 for the past couple years

corsair tends to be solid no matter what it is. If only they made mobos and graphics cards I'd have a bulletproof PC

Yes, but a cheap 650W would be better than a cheap 300W. Similar with the TX series. As capacitors age, their ESR increases and so does the ripple at a certain output current. Bigger PSU = bigger/better/more capacitors = more time before their ESR gets high enough to not be able to support the actual load.

kitamesume:
yes but it doesn't mean you need that much headroom, if you've done your math you'd see that if you factor in 30% capacitor aging you'll only need about 25% headroom(a 500watt setup would need 625-650watts).

although i've yet to see a table for aging%-per-year, i can't say how much years would it take to hit the 30%, but it shouldn't be hitting 20% capacitor aging at less than 3years.
and a fixed aging rate doesn't make sense either, otherwise you'll see PSU thats still working after 5years should be supplying near-nil of power.

as for an "overkill" psu, i don't think its a good idea either, unless you modulize your rig instead of swapping the whole thing that is.
for me though, i'm more in peace if i had most of the components as brand-new rather than having an overkill 10year-old PSU. as people says, nothing lasts forever.

So what happened to OP friend’s system in the end
