another quick question - power supplies

RufftimesRufftimes Member UncommonPosts: 46
Since you were all so helpful earlier....how much of a power supply do I actually need? We're doing an Intel build, and I picked up a 290x. I doubt very much we'd crossfire a second card, but you never know. An ssd and hdd, and that's about it. Is a decent 750w enough? Toomuch?

    If you're going to leave everything at stock speeds, a good quality 550 W power supply would be enough.  If you want to overclock without going for an unreasonably large overclock, make that 650 W.

    If you're not going to get a CrossFire rig up front, don't bother building around being able to handle one later.  If you want to upgrade the video card in two years, the sensible thing to do will be to get rid of your current card and buy a new card that doesn't exist yet but will then.  Building around being able to handle CrossFire can easily add $100 to the price tag up front for an option that you'll never use, as you need a better motherboard, case, and power supply to be able to handle it.

    I agre. 600-650W is enough for any CPU and single GPU build, with room to do moderate overclocks on anything, and pretty much as many fans/HDDs/SSDs as your system can support.

    It's a good size without going completely overboard and losing out on low-load efficiency or paying too much.
