Capacitor Aging?

Electrolytic capacitor aging. When used heavily or over an extended period of time (1+ years) a power supply will slowly lose some of its initial wattage capacity. We recommend you add 10-20% if you plan to keep your PSU for more than 1 year, or 20-30% for 24/7 usage and 1+ years.

 

In the bottom area of the page, it says that I should overshoot a little bit for my psu wattage, but umm for many of Linus's builds (among others) try to aim for a psu that is rated to be most efficient very close to their maximum wattage.

 

How much above my total wattage should I actually aim for when buying a psu?

The rig I'm planning to build will use about 800 watts so I'm planning on getting a [80+]platinum corsair 860watt psu, but should I aim for a higher wattage psu to compensate for capacitor aging? I'm planning to keep the rig while changing graphic cards every 2 or 3 years (so basically, the wattage I'm going to use probably wont change substantially for the next while

Give us a list of the specific components you are using and we'll give you a more accurate answer, but most likely, that 860W PSU will be over-kill for 90% of builds out there. Unless you're going for a crazy 3-way SLI configuration and a 4960X, you should be fine. By the way, that link just leads to an empty calculator. 

 

Rule of thumb:

For single GPU Configurations: 500-650W

For 2 way SLI/CF configurations: 750-850W 

For 3 way SLI/CF configurations: 1000W+

Umm I'm planning to go for a 4930k with (2) sli 780s and the watercooling kit http://www.xs-pc.com/watercooling-kits/raystorm-d5-photon-rx360-v3-watercooling-kit from xspc, I'm planning to go overkill a little bit for the time being because I'm planning to put waterblocks on my 780s after 2 months or so (or maybe wait for gtx 880s? idk) I'm gonna overclock my cpu a little bit (not balls to the wall so that I dont shorten its life span by THAT much), maybe 4.2 or 4.4Ghz range, put a couple of dim-ish lights in my system as an underglow with one storage hard drive to back up my two SSDs in raid0 as boot drive

would a 360 cool this and can u add another rad to that kit?

Yeah, I can add another radiator to the kit when the time comes, but the case I'm planning to get only supports radiators up to 360mm, so that would be the end of my radiators, not that I'd need SO many radiators anyway, I'm only planning to run moderate overclocks.

i was just wondering cos im planning a dream build one that i will get in like 5 years but i can upgrade the parts down the line (using pc part picker)
