my motherboard is 140W capable and officially supported the 140W phenoms.
As I wrote, I did puish my system. Daily stuff, 106W. Tv? 116W. Compiling some fat package? 160W. Gaming? 160-200W. Artificially maxing the system? 300W.
And with artificially maxing I used cpuburn cores*2+ut2004/vegastrike, while having find walking through my system.
Measured on the plug side. So the system itself draw even less.
I googled for your board and energy consumption:
doesn't look that high...
Not high powered PSUs make your system stable. High quality make it stable. And high wattage and high quality are not the same - and with some psu's even mutual exclusive.
In short, your PSU is way overpowered. You are wasting a lot of electricity and money.
no, it does waste electricity because it is so underloaded that it runs less effective
^That. Anybody saying otherwise needs to go back to school.n what? The PSU doesn't burn juice for nothing. Only for what's needed. It can *provide* up to 1000W, it doesn't *consume* 1000W by itself.

you are still doing it wrong! The watt on the package are about the OUTPUT not the INPUT!
650W PSU = 650W on the package and on the system side, but it sucks 812W from the wall socket.
In your case a 650W PSU would be way more than enough.
Also, one thing you get wrong is that PSUs have the best rated efficiency at certain loads. For example, most high end PSUs have 90% efficiency when the load is higher than 80%. If the load on the PSU is lower (way lower in Vincent's case) the conversion efficiency is even lower.
Read some basic electronics and figure out what happens inside a power source.
this story reminds me of american cars with V8 5.4L engines... at 100bhp...
Just cause the number is bigger doesnt mean its better. But some people never get it. YEAH 5GHZ!!!
less power efficiency does not mean less healty.
bigger one does also have bigger cooler passiv ones and aktiv ons
thats means if you only use 20% you also get a cooler one becourse of the bigger cooling system.
most of the time bigger one have also more quality becourse you cant build a bigger one cheaper thats becourse the cheap one will explote @1000watt outgoing.
but yes the efficiency is low thats right.
