What power supply would fit this build?

Here's the build I'm planning:

ASRock M3A770DE AM3 AMD 770 ATX
AMD Phenom II X2 555 Black Edition
LG DVD Burner
Western Digital 500GB 7200 RPM
GeIL 2 x 2GB DDR3 1333
SAPPHIRE Radeon HD 6870

I'm planing on slightly overclocking the cpu and gpu with stock cooling.

I've used a few tools online to try to figure it out on my own but I've got results ranging from 450W to 550W, I was looking at this Cooler Master 460W PSU but am not sure if it'll be enough.

  1. that CM is not a very good PSU.

    this unit is ok but a good price after the rebate and instant code

    probably the best value on newegg for 650w or under

  2. A 400W will do fine, but your build isnt very balanced.
    Unlocking isnt guaranteed, and getting a 6870 while youre on a budget isnt smart.

    Heres an alternative build with a TX650 (Can run 2 HD6850s), 1TTD HDD, USB3/SATA6 and crossfire for the same price as your original build AR.

    ASRock 870 Extreme3 + Corsair TX650
    AMD Athlon II X3 445
    SAMSUNG Spinpoint F3 HD103SJ 1TB
    ASUS EAH6850

    What would be the bottleneck in the build I listed? I don't really care much about having more than 2 cores since the games I play only take advantage of the first 2, what I like about the black edition is that it has the unlocked multipliers. So you think the 6870 is too much for this build?
  4. All I want out of this build is to be able to play Starcraft 2 with the highest settings at 1920 x 1080. I don't know if that helps but that's the only game I play, I might play FFXIV but not sure atm.

    That Coolermaster PSU is overrated crap. It is also missing protection circuits (review on HardwareSecrets). Avoid any PSU with a little voltage switch on it. Seasonic doesn't know how to make a bad PSU; Antec, Corsair, and Enermax are also good, as are some of the OCZs, including the ModXStreams.
    I also agree with Timop.
    There are some past articles (e.g. at Tom's) that show a fairly substantial gain from having a third core, if only for background OS tasks.
    You'd have to buy a cooler, but check out the 740BE. It may or may not unlock, but it has three cores and an unlocked multiplier: http://www.newegg.com/Product/Product.aspx?Item=N82E16819103699&cm_re=740-_-19-103-699-_-Product

    Edit: Ooh, Starcraft is very CPU-limited. You may want four cores right from the outset.

    I did consider that cpu but I wouldn't want to spend more than $20 on the heatsink/fan, are there any good ones for $20?

    Then the 6850 will do fine.
    The Unlocked Multi on the 555BE helps if you OC, but without a decent cooler you wont go too far.

    The 740 is a good choice, for the fan, the 212+ for $30 is great for $30.
    http://www.amazon.com/Cooler-Master-RR-B10-212P-G1-Universal-Heat-Pipe/dp/B002G1YPH0 on the 550

    However, the 445 isnt that bad either.
  8. It looks like I'll go with the 740 BE with the 212+ fan and 6850. I'm not sure about the mobo though, why did you recomend the ASRock 870 Extreme3 + Corsair TX650?
  9. So would this be a more balanced system?

    ASRock M3A770DE AM3 AMD 770 ATX
    AMD Phenom II X3 740 Black Edition
    SAMSUNG Spinpoint F3 HD103SJ 1TB
    GeIL 2 x 2GB DDR3 1333
    ASUS Radeon HD 6850

    If so, how many watts would this set up need?
  10. That is more balanced, yes. A good 500W PSU would be enough for that system, and allow a comfortable margin.

    Its a nice value and lets you crossfire in the future if you want the upgradability. The combos expired though.
    Now, consider this seasonic 650W, at almost the same prices of other 500Ws.

    that seasonic I linked above is no longer on sale. should have struck while the iron was hot ;)
  13. Well, this one's a little smaller, but certainly enough for a single card: http://www.newegg.com/Product/Product.aspx?Item=N82E16817151094
  14. yeah that 520w seasonic would be your best performance for your dollar at 600w and under
  15. I'm going to wait for a good black Friday deal on a 500W supply from any of these brands: Enermax, SeaSonic USA, Antec, EVGA, Silverstone, XFX, Corsair, OCZ Technology, PC Power and Cooling. I was under the impression Cooler Master was good brand from reading this.
  16. The Silent Pro line is supposed to be pretty good. Their older models, however, are garbage.
  17. Thanks for all the help every one, I'm going to have a hard time picking a "best answer" :p

  19. Well thanks; glad my contributions helped. What did you order?
    Anyway, have fun with your build.
