Power supply for nvidia 660

[Zeddey]

Hello everyone, I am currently building a new computer. I am using an i5-3570k cpu, cooler master hyper 212 cpu cooler, 1T seagate harddrive, 2x Crucial Ballistix sport 8gb 240-pin DDR3 1600 memory, Biostar TZ77b LGA 1155 intel Z77 MB, and an Nvidia 660 GPU (possibly a radeon hd 7870, Haven't made up my mind yet). I would like an opinion on what size power supply I should use.

Thank you.

In reality a 300W high quality PSU would be fine. Ivy Bridge and Kepler consume ridiculously low amounts of power.

It will probably pull around 300w from the wall. A quality 500w will do the job.

Thanks for the fast reply, how about the roswell capstone series? Are they any good?

I like to use the online calculators to see what a system will need . this is the one I use eXtreme PSU .

But what ever you decide make sure it is a quality PSU because the PSU is the heart of any thing electronic .

I just picked up a seasonic 860 Platinum today, quality unit for sure ..

Yeah I have to admit there is really little to dissaude me from suggesting higher than a 500W for such setups. Both items are very very power efficent.
