Will 650w be enough?

I was hoping some of you guys could tell me if this power supply will be sufficent enough for me....
http://www.newegg.com/Product/Product.aspx?Item=N82E16817171023
650wat psu for:
hd 4870 1gb
640gb hard drive
internal wireless n
q9550 cpu
8gb of ddr 2 800mhz ram
and x-fi xtreme sound card

I made to research and make sure all of my connectors are good.. and it is compatible
I know the bare minimum is 500ws for 4870 but... i know i have alot of other energy hungry parts too
again my question is:
Will a 650w psu be more than enough to power this build?
thanks!

  1. 650w is more than enough. There is a website where you can calculate how much power your system needs, it's http://www.thermaltake.outervision.com/Power.

    Using this on what spec's you gave it calculated you needed 347w. People focus too much on large watts; it’s more important have a high quality p.s.u.

  3. Sorry about the double post, I tryed to edit it.
  4. definitely enough, u can even overclock if u want. will u be getting a second GPU later down the road though?

    also, the "bare minimum" ur referring to is not a minimum. its a recommended wattage, but systems vary widely, especially between overclocked and stock systems.

    *edit* took the liberty of fixing jamie's link http://www.thermaltake.outervision.com/Power
  5. Well, a 650 watt power supply is more than you actually need. On the other hand you'll be ready for a couple of upgrades. My personal favorites are Corsair power supplies. I build pc's for friends, neighbors, and girlfriends. I use Corsair exclusively. The psu's are rock solid and very stale. Here's a link to a Corsair 650TX which can be had at newegg.com for $69.00 after mail in rebate:

  6. My system has a hard time using 350 from the wall(so the actual use is lower).

    For best efficiency try to get close to 2x what you need, In your case, I think you are right on track at 650 as long as its a good psu.
