large enough power supply?

[gellin]

I'm looking to build my first computer and here's what I plan on getting so far:

AMD Athlon 64 4000+
2GB DDR SDRAM (PC 3200) Dual Channel
Geforce 7800GT 256MB
ASUS A8N-SLI Deluxe Socket 939 NVIDIA nForce4 SLI ATX AMD Motherboard
16x dual layer dvd burner
Sound Blaster Audigy2
Western Digital Raptor WD740GD 74GB 10,000 RPM 8MB Cache Serial ATA150 Hard Drive

Will a 450 watt power supply be enough for this? What if I decide to upgrade later and get another 7800GT and 2 more gigs of ram?

Also, let me know if there's anything I'm missing or something way better that I should be getting.

Thank!

I have a very similar rig with a 420 Watt PS if I can remember correctly, anything 400+ should be fine for you...

You want 2gb of Ram, and a 10,000 rpm seriel ATA Raptor, but you want to scrimp on a Psu?

Get the most powerful psu you can possibly afford, and make sure the 12v has HIGH current delivery, not just the 5v rail.

Here is a great example, and a DAMNED good deal from newegg.com

AMD Athlon 64 4000+???

Go with the X2 3800+ or 4200+ you will not regret it. You can burn a DVD, while decompressing a rare file, while downloading off of newsgroups, while surfing the web with very little lag at all. Simply amazing. It's the multitaskers dream chip.

Check newegg id round id just get a 500 cause you never know how much shit your gonna be throwin in it once your "done" building it lol.

Get the PSU Krell suggested. I bought that exact one a couple months ago, and it's great!

[ccc1005]

I have a 480Watt PSU actually, from Thermaltake and it has a fan speed control and everything, quite a nice unit.

Is that supposed to be 740 GB? Sorry, but 74GB seems a bit odd. Even 740 seems unlikely for a single drive.

74 GB is correct.

Nah its actually 74GB, does seem odd but the 10k RPM drives are commonly in that size...

The wattage rating on power supplies don't mean much.

The number of amps you can get off the 12V rail is a much more accurate way to guage a power supply.

Also, buying a trusted brand name means it's less likely to damage any of your components if it fails.

My AMD 3000+ can do all that with only 1 gig of ram. Just last night I was running Winmx, DL'in about 5 files pretty fast, using Sonic My DVD to convert some files to DVD format, and surfing the net with no lag at all. The DVD turned out fine too. I didn't build the fastest system but by god its very stable while multi tasking.


I think most people go over board when building a PC. If youre just using your computer to download files and check your E-mail, you can get by with much much less. If your building a gaming rig, it sounds good although I think my PC can play anyhing out there with no problems. Plus it was cheap as hell to build. I use mine for editing video VERY large video files. I do need to add another gig of ram soon!


EDIT: Oh yea, don't be cheap on the PS, I went with a 500watt model with a built in light, multicolored fan with speed ajust..

[.:sp00ky:.]

I totally agree with mel iv got a 3200 and to test it out i had bf2,fear,nero,some dvd converters and another 40 programs including p2p running and it ran fine cpu didnt even reach 100%

can't see the point of duel cpu,or sli gc for that matter yet.

[ccc1005]

Well after converting over 50 movies to DIVX this summer I could have definately used a multi-core processor, unless you are doing sometime like that which uses a lot of CPU constantly, it really isn't worth it.

450 Watts might not be enough.

You should buy one of these to be on the safe side: Link
