this makes complete sense to me. looking at the link you posted earlier, I see that a PSU is optimally efficient between 40% and 60% load. so, if you're using a maximum of 30% of your PSU's actually potential output under 100% load, you've actually adversely affected the efficiency of your PSU. kinda like it hasn't "warmed up yet" (if you've ever driven a car after first starting it when it's really cold out).

I have been saying dor a longtime that hardware use a lot less power then you think it does

And you should ever buy too much wattage

Many dont want to belive that and have even been attacked and called a liar for saying it

TwoCables have been saying it for years as well

So my 760Watt will be more than enough for 2 HD7970's (Matrix)?

it will be enough, I think, but it wouldn't put your system within the sweet spot. you'd be using 85-90% of your PSU's potential output.

again, though, I agree with shilka that the efficiency should be a secondary contributing factor to your purchase decision. wattage comes first, then most people would probably go by noise level after they've determined how much power their system needs. also things such as build quality, company reputation, technical support (like shilka said) would probably be best weighed out before anyone looks at the efficiency rating.

running 2 overclocked Titans and a 2600k at 4.8, I figured a AX1200 would have been a good choice...

I think if you use a PSU calculator, and this chart:



and plug your numbers into this equation: P = S+(S*L)

where P = PSU max. output ("rating"); S = required system wattage; and L = 50% PSU load (optimal PSU efficiency)


EXAMPLE:

P = ?
S = 650W
L = 50% (optimal efficiency)

P = 650+(650*50%)
P = 650+(650*0.5)
P = 650+325
P = 975

so you would want a 1000W PSU if your system uses 650W @ 100% and you're hell-bent on having your PSU run at top efficiency

otherwise, just get a 700W or 750W

there are, other considerations that go into this I suppose. such as capacitor aging within the PSU (which will degrade its efficiency over time/use), and how much average system load you actually use. meaning, if it's a bitmining rig, 100% is a safe bet for your system wattage requirements. if you're a gamer, maybe you only use 60% at maximum. BUT, and this is a big but, you HAVE TO plan worst case scenario because if you ever do hit 100% system load and that exceeds your PSU's max. output, that's an uh-oh!!

Move this to a PSU thread and post more pictures of Troopers

If you dont overvolt them yes

Can you get replacement 120mm fans that come with the Stryker? Cannot seem to find them.

Why not just get another fan
