850W PSU recommendation?

Hi there, I am about to purchase a PSU and need help on which one to get, I will list all of my options (I have heard great things about all of them).

As usual, it would be great if I could get the cheapest one, but I am looking for what I do and don't need.

I will list my choices in cheapest to most expensive:

1) Silverstone Strider Plus 850W ST85F-P
http://www.pccasegear.com/index.php?main_page=product_info&cPath=15_535&products_id=13278 $159 (such a good price for the performance, am I right)?

2) Silverstone Strider 850W Gold ST85F-G
http://www.pccasegear.com/index.php?main_page=product_info&cPath=15_535&products_id=16519 $209

3) Corsair HX-850 Power Supply
http://www.pccasegear.com/index.php?main_page=product_info&cPath=15_535&products_id=12111 $219

4) Seasonic M12D 850W Modular PSU
http://www.pccasegear.com/index.php?main_page=product_info&cPath=15_535&products_id=12910 $223

It would be excellent to get the cheaper one that is more than $40 cheaper than the next, but is it worth it or is it not?

Thanks and I would like to see what you would say about this.

  1. The first silverstone should work fine. The price is close to newegg's.
  2. I know that it would work fine, but is there anything about the other PSU that is worth getting?

    I will be running 2 560 Ti's in SLI (overclock them a bit) and a i5 2500k clocked to maybe over 4.8GHz.

    Thanks.

    I agree the Strider plus units are very good.
    A good 750W psu will handle your specs no problem.
    Oc'd i7 965/x58 platform testbed = uses more power then a SB platform

    Btw you won't get any gaming performance benefits over 4.5GHz.
  4. Thanks! Do you think the new Enermax Platimax 750W will handle an over clock 2500k at 4.5GHz and 2 MSI Hawk 560 Ti's in SLI overclocked to about 1GHz each with room to spare?

    Thanks!
  5. Can anyone help me here?

    Thanks.
  6. There's a program to test your system for wattage requirements, but I believe you have to have it running to test it accurately. If in doubt, I would go for the power supply with the highest 12v amp ratings.
  7. Thanks.

    Do you think I should just get the 850W SilverStone $159 one?
  8. I've used a silverstone cable select model briefly, and it worked fine. So the silverstone would be my first choice, unless a newegg reviewer says it's a noisy model. I hate noise.
  9. But what does the other PSU have that the 850W silver doesn't? I just want what I need.

    Do I even need 850W?

    Thanks!
  10. You'll need every bit of 850 watts for overclocking and sli. If your budget is strained, get a cheaper video card or motherboard, but don't skimp on the ps.
  11. Thanks, i might consider getting a 580 then with 750W? What do you think?

    Thanks.
  12. Yes a quality 750W will run a 580 or 560ti SLI no problem.
    Here's some good units.
    Corsair HX-750 Power Supply
    http://www.pccasegear.com/index.php?main_page=product_info&cPath=15_354&products_id=12110
    Antec TruePower TP-750 750W
    http://www.pccasegear.com/index.php?main_page=product_info&cPath=15_226&products_id=11005
    Or go with the Strider Plus 850W.
  13. Holly shizz man, theres no need for that much power hahaha... im sure a 700w would run that fine. 560's in SLI take no more than 350-400w so add a 125w cpu and extra crap you would be 100% fine.

    560's in SLI use @ 300w so yeah! i've been trying to get that point across.
    Like you say a bit more if oc'd.
  15. So would I be fine using 750W for 2 x 560 Ti in SLI, a fan controller, 10 high performance fans, 2500k @ 4.5GHz, 2 SSDs, blu ray reader/writer with room to spare? I might even OC my GPUs.

    Thanks.

    Thanks.

    Both 750w units i listed can push out over 900w no problem.
    If you have concerns buy the 850w Strider +.
  17. BTW, what uses more power? A 560 Ti in SLI or a 6950 in crossfire?

    Thanks.

    Thanks.

    6950's use @330W.
    560's @300W.
    Both will use more when overclocked.
  19. Thanks!
