Analyze my new build for power adequacy

[trogbard]

I have purchased the following power supply and want to make sure it will be OK for my build. This will be my first one so I do not want to make sure I have all the right parts. Please also let me know if any of my other items dont seem right. I plan to use this to play sc2 and mmorpg

I looked at the manufacturer website and could not find power requirements except for the graphics card.

Anything?

 

[trogbard]

If possible I would really like some help because I still have time to cancel my order from newegg.

Did I do something wrong when posting?

I may decide to overclock in future. Probably will not add another gpu as i think the card i picked is a really good one.

For gaming? Can you get a better video card? HD 6870? 6950? 560tI? You can get 2x2G of RAM now if it's a tight budget.

This HDD is just as fast and bigger

The PSU is fine for any single video card out there.

Thanks for the reply.

i thought that the video card i had was a better video card. This wont run sc2 and/or other mmorpg at high levels?

 

[trogbard]

Also the HDD has only a 32 mb cache and is 3 gbs, doesnt that make a difference? WD is also apparently a very reliable company from what i hear. Is Samsung the same?

 

[trogbard]

The video card and RAM actually just shipped I will return though if you say that this is not good enough to run these types of games without problems. I am planning on using my xbox for third person shooters so i didnt think i needed a super computer for the games i would be playing on it. Maybe I am wrong

 

[mosox]

That video card is good for those games, keep it. The RAM is fine.
