New Computer, need advice

[Eric998765]

i know there are probably a lot of threads like these around, but i need to see if my parts will be good enough. the biggest issue for me is what size power supply to use. i used a calculator i found in another thread, but it said something like 1300 watts, and i know there is no way i'll need that much. so here it goes, the list of parts i'm hoping to use (all from tiger direct):



EVGA GeForce 8800 GTS Superclocked / 320MB GDDR3 / SLI Ready / PCI Express / Dual DVI / HDTV / Video Card

Asus P5N-E SLI NVIDIA 650i Socket 775 ATX Motherboard and an Intel Core 2 Quad Q6600 2.40GHz Socket 775 OEM Processor

OCZ Gold XTC 1024MB PC6400 DDR2 800MHz Memory

DCLCD by Sceptre DCL20A 20.1" Widescreen LCD Monitor - 5ms, 1000:1, WSXGA+ 1680x1050, DVI with HDCP, VGA(D-sub), Built-In Speakers, 16:10 Aspect Ratio

Turtle Beach Montego 7.1 Dolby Digital Live Surround PCI Sound Card

Seagate / Barracuda 7200.10 / 500GB / 7200 / 16MB / Serial ATA-300 / OEM / Hard Drive

Ultra / X-Wind / Socket 775 / Copper / CPU Cooling Fan to 3.8ghz

and one of my current hard drives which is a 250GB seagate.

also, it needs to be known that i am planning to overclock the cpu to 3ghz and possibly overclock the ram, but i need to read up on that one first.

so what sie power supply do yall recommend? also, is there anything i left off the list other than an os? (planning on using xp)

thanks for all and any help!


edit: silly me, i'm getting logitech 5.1 speakers and a wireless/bluetooth keyboard and mouse combo of some sort

I would go with a P35 based motherboard rather than the 650i.

Memory is overkill. You can get the Q6600 to 3Ghz with this memory...

If you want a sound card, I'd go with this one...

As for a power supply, the Enermax Liberty 500w, or the Corsair 520W will do fine.
