New build - Gaming and programming

[WoodenMarker]

I just checked my numbers, I do indeed use 100% peak load + OC'ed CPU.

His system on day 1: recommended atleast 721W

25% aged (3 years of normal use): 888W

40% aged (5 years): 989W

50% aged (7 years): 1056W

 

The recommendation is based on peak draw of the whole build + 150W.

The time to age the capacitors is diffirent with every PSU, AX from Corsair for example would take longer to age it's capacitors. But still, RM850 is a better deal the AX760i and the fuctionality is the same.

Again, forget about the 'recommended wattage'. Actual power draw is much less.

Using a load meter, you can see how much you are actually drawing through the socket and that's before you even consider the efficiency of the psu.

Here you have the normal draw numbers, it's that - 150W

Day 1: 580W

25%: 740W

40%: 840W

50%: 900W

 

I'd say 20W headroom after 3-4 years of usage isn't "enough".

Where are you getting these numbers? 

If you couldn't watch the video, here's the gist:

He has a watercooled system with a 3770k at 4.7 ghz, a 680 oc'ed to 1280 mhz, 12 corsair fans, etc. The system at full 100% load took ~350w from the wall.

Basically, you use a lot less power than you think.

That is a reallistic number for 1 680, but you can expect atleast 150-200W more with 2 780s. I have my numbers from http://www.thermaltake.outervision.com/index.jsp, it is the best calculator around any many forums recommend it.

The calculator recommends PSU wattages and not power draw.

They say that they follow the pattern of real draw + 150W, I've said that earlier.

I know you said it but where did they say so?

Somebody explained in on a forum, Toms Hardware I think.
