Is 550w enough to power this system?

Hello,
I'm just about to upgrade some computer parts and I'm wonder if my current 500w power supply would be enough for everything. Here is what I'm going to be running

mobo:
ASUS M4A87TD/USB3 AM3 AMD 870 SATA 6Gb/s USB 3.0 AMD Motherboard

CPU:
AMD Phenom II X4 955 Black Edition Deneb 3.2GHz 4 x 512KB L2 Cache 6MB L3 Cache Socket AM3 125W Quad-Core Processor HDZ955FBGMBOX

RAM:
G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-4GBRL

I will be using 1 harddrive, 1 Dvd drive, and I won't have more than 7 fans running.

Thanks!

Here's a link to my current power supply:

  1. Best answer
    Yes, you'll be OK.

    Fans do not use much power. Figure that 1 amps at 12 volts will power 4 fans.
  2. He OCZ 550 is enough. The 460 is recommended 450W.
  3. It depends.
    If you are not overclocking, and you have a reliable (can usually tell by brand; eg antech, corsair, xfx) PSU, then you should be fine.
    If you are overclocking or your PSU was just a freebie that you got with your case, then I would condier upgrading :)
    Hope this answered your question,

    edit* I missed the link on your PSU. And yes, that PSU is fine.
  4. Thanks guys! I was just unsure, since my friend was saying my PSU wouldn't be able to handle any of that stuff at full load.

    Also, would this case be able to keep things mildly cool(I won't be overclocking as of right now)? As my friend also claims that my case will NOT be good enough.

  6. A 460 is not all that hot (temperature wise) of a card. Any case with good front-back airflow will probably be fine. Your friend sounds like one of these elitist "buy the most expensive or it wont work" nutters. What is your current case?
  7. My current case is an Lexa S from NZXT.

  8. 4 fans: front, rear, top, side? IF so then your case looks plenty good. Buying a new one would be a waste of money unless you are actually experiencing heat issues. I wonder what case he has that he thinks is so much superior.

    He also mentioned that the gtx460 I'm going to get is going to get lower performance than his current 5830. Is that true?
  10. Your case has fans in all the same places. It may be made of cheaper plastic and the fans are smaller but you case is plenty good for any of the newer more efficient graphics cards.

    Read Toms review of the 460. Check the charts on the games like you play. The 460 1GB almost always beats a 5830. The 768MB version doesnt. The performance is so close you probably wont be able to tell the difference. The 460 will let you use PhysX, which is visually impressive in the few games that use it. Nvidia has a better track record with drivers not causing freezing and such.

    If you ever move up to an intel motherboard you will be able to get another 460 and SLI them much better than a pair of 5830s would.
  11. I'm getting the 1gb edition. I was planning on going SLI sometime later, with an SLI AMD board. I'm still hesitating whether i should go AMD or stick with Intel, as this is going to be my first AMD build.

    Do you have any suggestions on whether to go AMD or Intel? My current budget for CPU/Mobo/Ram is below $430, but I'd be willing to wait a bit more for more cash if Intel's CPU's are much superior than the AMD ones. I'd be using the computer for mostly gaming, movies and light music producing.
  12. RAM is $100 either way

    An intel p55 motherboard that handles x8/x8 SLI is $180-$185

    An i5 760 is $210 - you can often get better prices in-store at microcenter
  13. Alright, Thanks! I'll take those into consideration :) Thanks for your help!
