Build PSU help

[Vrman]

Hi I am planning to build my first Gaming PC for around $700 - $750 and am looking for advice on whether this build will work well, especially will this build (esp. the graphics card) have enough power to work or is it wasting too much power

The Build (all parts from newegg.com)

OCZ Platinum 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory Model OCZ2P10664GK - Retail $71.99

I am pretty much basing this build on the Phenom II processor and the 4870 video card. The rest are just the ones with the best rating on newegg.
any and all help is appreciated

That PSU is overkill. 500W is more than enough.

Well thats what I thought at first. I had picked a 550W PSU but one of my friends suggested to get a 600+ PSU just to be safe. Also I plan to eventually upgrade to 8 GB and double up the video cards or just get a better one(aka lot more powerful one) in the future.

Also the 550W is just around $60 so i am paying $20 more for a much more powerful and safer PSU

Finally I am sure that in just 6 months - 1 year I will have to start OCing to be able to play the latest games in medium-high settings, so i am planning ahead.

does this make sense? or is it still overkill?

The power consumption of RAM is negligible compared to eg video cards.
Do you plan on upgrading or adding another card? If you plan on adding another card, the 700W PSU makes sense.[/quote]

No, you are paying a lot more. The 700 watter will be very inefficient at the load levels you are throwing at it. Thus, you will use more quite a lot more power than if you bought a more suitable PSU. If you use your computer a lot, this can add up to quite a lot of money spent on power.

Finally I am sure that in just 6 months - 1 year I will have to start OCing to be able to play the latest games in medium-high settings, so i am planning ahead.

Sell the old video card, and used the money saved on the bigger PSU and power to get a newer video card instead.

Here you go. 700W (modular too) for $50 after rebate. If you will stick with 1 video card (unless it's a dual gpu card), I'd recommend the Corsair 400W for $30 after rebate from newegg. It has 30A on a single 12V rail, which should be enough.

$50 saved on the PSU, $50 from selling the old card, and $50 saved on power. There's your video card upgrade next year
