Which power supply?

Well I am building my new gaming rig and know I need a new power supply. My future specs will be:


i5 2500k
EVGA GTX 560 Ti 448 core
ASUS Maximus IV Gene-Z/GEN3 LGA 1155 Intel Z68 HDMI SATA 6Gb/s USB 3.0 Micro ATX Intel
Probably 16 GB RAM (Don't think that matters but whatever)

I also got the Antec Nine Hundred Black Steel ATX Mid Tower Computer Case which I hope will be big enough for all of this.

I am also planning to OC the 560 and i5, so would that require more watts? I am just looking for a supply that can support all of this. I don't want the minimum. If possible, the maximum for all of this. I would rather be on the safe side and spent a little extra so my computer can keep up with all of this. I also hope it doesn't go over $100.. but if it does post it and I will consider getting it. If I must post any more specs just tell me as I never know what to post when I need help. :lol:

Thanks!

More about which power supply
  1. the maximum power draw from your system will be under 400watts even if you OC.

    Minimal needed will thus be above 450 watts.

    I don't know what you mean about maximum but you can buy a 1000w psu and it will still not do anything more or less than a 500w for your system.

    you can get this for best bang for your buck.

    also if you want to sli then you need a 650w or more psu.

    By maximum I meant for a supply that can do better than the minimum, but If you said it wasn't to make a difference than forget the maximum business. I thought if I had a supply that would be too low my computer would start on fire, lol. But if anyone agrees that 500 is more than enough, I can go with the one you posted. $40 bucks is a great deal.
  3. Stock or overclocked ?

    As you can see here, the actual tested power consumption for a rig with an overclocked 560 ti-448 is over just over 500 watts (503) .....

    Adding a second adds 210 watts////713 total.

    I'd not use less than a 650 watter for a single card, 850 watts if you are planning SLI in the future.

    Remember, it's not just about being able to get your rig to not blow up when ya stress it, it's about being able to maintain extremely stable voltages while everything is OC'd to the wall. As PSU's are stressed, voltage instability starts to creep up and when your MoBo / GPU VRM's are trying to maintain stable voltages with varying voltage inputs, the wavering voltage / current is what causes system instability.....and hence ya just might not be able to get ya OC as high as you'd like.

    Wondering why ya can't get the same OC as the other guy ..... run OCCT and graph the voltages over the GPU / CPU tests.

    Thanks for the reply and info. I do not plan to SLI. As for single or more, I just plan on using one card. As for the overclocking, I again do not know much about it. As far as overclocking would go, I would only crank it up to those people recommend it to. I would not go over and risk it breaking on me. And if I was to get a 850+, which would you recommend as far as best value goes?
  5. The 448 uses more power then a regular 560ti.
    Probably about 200W once oc'd.
    http://www.geforce.com/Hardware/GPUs/geforce-gtx-560ti/specifications
    The miminum recommended psu is a 550W for a 448 core.
    I'm not saying the Antec unit is bad,it's a good unit.
    Probably be fine,maybe a tad loud once you oc everything.
    Personally i'd buy a 600W+ unit for your specs.
    Especially if you can afford it now.
    SeaSonic S12II 620 = non-semi-mod version of unit i posted earlier.
    Higher efficiency Bronze and 5yr warranty.

  6. That makes more sense now, thanks for clearing it up. As I am reading reviews I keep noticing the word modular. What is this? Why do so many people keep complaining about this not being modular? Does it make a difference?

    Probably not much for your situation.
    A semi-mod might be useful in your case idk for sure.
    Fully modular - no fixed cables to the psu = use what you need
    Semi-modular = has the important cables attached to the unit= others are user selectable
    Non-modualr = all cables are fixed(attached)to the psu

  8. thats with an OC'ed 130 watt 920. your system will draw less power.
