How much of a Power Supply do I need for this rig?

I have reconfigured my specs since yesterday. See Here

I was just wondering how much of a power supply I will need for this rig.

Athlon 1000 266 FSB
Tai-Sol CEK733092 Socket A CPU Cooling Fan
Epox 8K7A MB
Crucial DDR PC2100 (256 MB)
Asus V7100 Geforce 2
Western Digital 30GB 7200 rpm
US Robotics 56k modem (PCI Hardware)
Viewsonic 17" E70F .25 1280X1024 Flat Screen
CD-Rom
Gonna use On-Board sound for now.
Power Supply ??????

Again, no overclocking planned any time soon.

The reason I ask about the Power Supply is because I've read several posts here and other places that deal with people not having enough of a PS to run their system.

Oh, I guess I should have mentioned it in the other thread, but I'm trying to build this for under $1000.

So, 300w enough? 350w? 400w?

I gather that I need to look for an AMD recommended PS, also.

Thanks for the help yesterday, too. 😀

i'm sure you'll hear otherwise...but 250watt should be enough. i ran a system just like that plus a few case fans, one more hard drive, and 2 cd-rom drives (dvd and cd-rw) with a 250 without problems. however, i DEFINATELY recommend going with 300watt. when i added a 1.33ghz t-bird and a geforce2 ultra the 250watt wasn't enough...300watts was enough. go with 300watts (and a good name like antec, sparkle, etc...)
 
I got a 250w cheap brand and running all this:
PIII 800E @ 920
Via Apollo 133A Chipset
Asus P3V4X Mobo
LG 52x CDROM
Lite-On 12x8x32 CDRW
Maxtor Diamond Max+ 7200RPM 30gig HD
Maxtor 10g 7200rpm HD
Asus V7100 GF II MX @ 190/190
Generic 256m PC 133 CAS 2 RAM
Creative Sound Blaster Live! Value

Its fine...
 
i would get a 300 because it is a royal pain when you install a device, and suddenly there is not enough power......

Get a 300W. The price difference isn't enough to warrant not doing so. Who knows what you may want to do in the future, add another hard drive, some fans etc?

300W to be certain.
 
350W, why shoot for "just barely enough"? Extra wattages never hurt, 350W isnt that expensive anyway.
 
I have almost part for part....useing Enermax 350 Watt Whisper...

I think the 350 is Overkill for me....had CasEdge/Foxconn 250 watt PS...with same sys..

did not see any diff with the 350...temp,etc..
 
The monitor has little effect on the PS. The PS spits out DC, your monitor needs AC power. If you can actually plug the montior in, the PS does nothing but offer a place to plug in the monitor.

Any case, I think the rule of thumb is that most computers use on average about half the rated power of a properly matched power supply. I think 300W is quite sufficient for your intended rig. Power usage just shouldn't peak at some level above the rating of the PS, at least not for very long or many times.
