Default PSU WATTAGE !!!!!!.... plz respond ><

I'm planning on building an i7 sandy bridge 2600k(overclocking 4.2 ghz+) system with a single gpu amd 6950. One ocz 64gb/60gb ssd, one 7200 1TB HHD, two DDR3 1600mhz 2 gb ram, cooler master 212 plus cpu cooler, and a cd drive.

How much wattage would it require and which psu should i get if my budget is only around 70 dollar?

i know there is psu calculator out there but sadly the dont have the new sandy bridge as an option when choosing cpu... so i need suggestions from experienced ppl thx :)

600 W would be fine for that.

70$. Such a nice system, and you skimp on the most important component. I would not.

I concur, 600w is plentiful.

I agree. I'd say get the corsair cx600 - good psu for the cost. around $90 with taxes if I remember correctly.

You could always pick up a Corsair TX650 used as they are running within your budget if used it a route you'd be willing to go.

Best advice out there right now mate.

Don't make the PSU the cheapest component in your system.

Silver Stone has the Strider Plus units going fairly well priced, as well as the mentioned Corsair ones. They are solid Power Supplies.

I can concur with the estimate of 200-300W. My rig with an i5 2500k overclocked to 4.2 GHz (CPU folding, GPU idle) only pulls 200W FROM THE WALL so what it's getting from the 12V is less.
The following Seasonic should do the trick if all the wires are long enough:
NCIX.com - Buy Seasonic S12II 520W EPS12V 20/24PIN ATX Power Supply Active PFC 80+ Bronze 6+8PIN PCI-E W/ 120MM Fan - S12II 520 In Canada. ($65 before taxes with NCIX's sale)

Note that you'll limit yourself to one high-end GPU with that power supply, but that's about as much as you can get for a power supply that's around 20% of the price of your CPU...

I have seen many different psu wattage calculators online like :

eXtreme Power Supply Calculator

Does anyone else have a favorite they like to use?
