Power use of an amd1600+?

Trying to decide if I should run my old AMD 1600+ as a linux box crunching folding@home 24/7. My aunt died of cancer at 29 so anything I can do is what im trying to go for here. It would only cost me like $40 to get a new case & PS to run it.

My question is here is the config, how much power do you think it would use?

AMD 1600+
256MB ram
1x60GB HD
ATI Radeon 9000 64MB
PCI LAN card
Old DVD ROM drive

No keyboard, no mouse, no monitor. I have a KVM and my lcd has an analog input that will be used.

I'm thinkin if I buy a crappy PS & case I woudln't see better than 75% efficiency so at full cpu load (100%), maybe 150W?

@ 8c per KWH that would be about what, $8.50/mo in electricity? Winter is coming up so I guess it could help heat my apt 😉

Am I off on the electricity calculation?
 
I ran:

Amd athlonXP 1800+
512 DDR pc2700
maxtor 60GB
FX5200
CD-RW and DVD-drive

with a no-name 200 PSU, the PSU died after 4 years, now I have a no name 500W running it 😛 shud be good for another 4 years.

An Antec 200W-300W will be more than enough to run that comp you listed 🙂.
 
What I mean is, do you guys think it would be 150W? I just found it in google, the cpu at full load uses 62W. Would it be 100W for system or closer to 150W?
 
go here and figure it out based on what you have... http://www.jscustompcs.com/power_supply/
based off of what you specified, it would come to 203 watts, subtract 8 watts for no keyboard or mouse, gives you 195 watts at full load....you didnt specify type of ram, which makes only a couple watts difference....so i personally would get a 300 watt minimum if its going to be a generic no name power supply.....250 if its a good name brand one..
 
jsc is very inaccurate. hugely overestimates. I run my pc on a quality 240w power supply even though jsc says i need ~300w.

there is a better calculator that actually calculates amperage of components.

I have taken the liberty of calculation for you.

ATX Mb Athalon with +12plug
Athalon 1600+xp palomino
4800rpm generic fan
2x pc2700 samsung ddr modules, max load
generic 60gb hdd
liteon dvd 4x drive
ati RADEON 8500(basically a faster 9000)
AMd reference PCI NIC card
120mm 2800rpm fan
90% utilization, 10% utilization for fans & drives(worst case scenario)

3.3V line MAX 7.1 A or above
5V line MAX 7.7 A or above : **very important
12V line MAX 12A or above : **very important
3.3 + 5V combined MAX 62.1 W or above : *important
3.3 + 5 + 12V combined MAX 206.3 W or above
total output 216.3 W or above

forget wattage ratings, pay attention to amp rating, espically the +12V rail.

Ok both of you guys need to realize that these numbers are for each component using 100% load. There would be virtually no HD usage (just spinning), ram would prolly be at 1/2 capacity, CDrom wouldn't be in use, and video card would be almost 0. Only thing that would be at 100% would be cpu & mobo.

Combined thats prolly about 90W. Including a 25% power inefficiency of the power supply, that would be about 115W. So it would cos tme between $6 and $9/mo in extra electricity. Not bad if I can get 90 work units a month.

 
If you have to heat your home/apartment, then subtract the cost of operating the CPU from your usual heating bill. If you have to remove the heat by means of air conditioning, then multiply the cost of operating the CPU by about 3, then pro-rate that by the amount of time that you run the AC (day, night, all the time, whatever).
 
if you read my post closely i said it was calculated at FULL LOAD(100%) and i also said a quality power supply arouns 250w would be fine......but i suppose i need to draw a picture that shows the calculations at full load and then another showing that it doesnt run at full load and therefore uses a smaller percentage of the power supply, i presumed you were smart enough to figure that out, guess i was wrong.....and jcs is not way off....different people use different methods for reaching the conclusion, but all are in the same ballpark, it also depends on the components....the calculator uses an AVERAGE of most components and runs with that.....you all need to understand it is a estimated usage...not an exact usage figure.

WRONG. Still way off bud.
 
You don't get much from many of the widely-available PC psu's. I've had 450 watt Okia, Powmax, Raidmax, and another something-"max" with the tops off. They compare at best to quality units with ratings in the 150-180 watt range! I suspect that this three to one ratio, roughly, is why the various calculator setups using wattages all come up with such elevated numbers. You get a cheap junker ChiefMax psu, and you better get the 500-plus watts rated one that is equivalent to maybe a 200 from a good maker!

LxMxFxD3, how is it way off....how am i wrong, please explain in detail so i may understand the error of my ways....in other words....dont just say wrong.....back it up...
