So is discussing the toaster oven not an option?

no we can discuss the toaster oven if you like. Gotta say it's by far the best toaster oven eva.

Why do you need that much power? What are you going to be running in it?

Well i like to bake a lot of cookies and pizza.

850 watts isnt that much...

Not really.. but it will be enough for what i want.

i7 2600K

and either a radeon 6970 or a gtx 570

Actually it is. I'm running an 8800GTX with an overclocked cpu and 7 case fans all off a 420w psu. Been running for 2 years now with no problem. Without multiple graphics cards I just don't see the point in having a psu that large...I guess headroom?

1. EFFICIENCY — This is a measure of AC-to-DC conversion efficiency. The ATX12V Power Supply Design Guide recommends 80% efficiency or better at all output power loads. 80% efficiency means that to deliver 80W DC output, a PSU draws 100W AC input, and 20W is lost as heat within the PSU. Higher efficiency is preferred for reduced energy consumption and cooler operation. It allows reduced cooling airflow, which translates to lower noise. The 80 Plus Gold standard requires 90% efficiency at 50% of rated load, and 87% efficiency at both 20% load and full rated load.

At the super low 20W load, efficiency was quite good at 65%. Efficiency rose quickly as the load was increased. 80% efficiency was reached around the 55W mark, broke 87% by 150W (easily meeting the 87% requirement at 20% load, which is 170W), and it reached 90% at 250W. At 200~350W, ~90% efficiency was maintained. With higher load and higher operational temperature in the SPCR test box, efficiency dropped a bit. At 50% load (425W), with temperature at 35~38°C in our hotbox, 90% efficiency was not quite reached; it was just shy of 89%. At full power, the efficiency dopped down to 83.4%, a full 3.6% under the 87% required by 80 Plus Gold — but by then the internal temperature of the hotbox was 44°C.

The failure of our sample to meet 90% efficiency at midpower is somewhat unusual, but the drop at full power is not. The 80 Plus validation testing is done at typical room temperature (18~28°C) while SPCR's test setup feeds the heat of the PSU output back into its operating ambient, which makes for a much hotter, more demanding and realistic high power load test. Most PSUs with 400W+ rating that we test do not match full power 80 Plus efficiency test results due to our extremely hot conditions.

i figure i will actually use somewhere around 50% of the PSU available power and be in the super efficient and quiet realm. The AX850 fan doesnt even spin until something like 20% usage. It's going in the living room and i'm going for a semi-quiet while gaming and near silent while surfing build.
