How much power?

[n3ll]

I'm planning to upgrade to an athlon 64 x2 4400+ from a 64 3200+. I have a 480 task PSU. I wonder if it would suffice with my system.

The specs right now:
msi k8n neo4 platinum
Creative audigy 2 zs
Ati x800gto
4 x 512mb geil ddr
Benq dvd-rw
asus dvd-rom
3 x 120gb seagate 7200rpm sata hdd
logitech mx518 mouse
logitech media keyboard
ttake big typhoon(HSF)
and a floppy drive
housed on a ttake shark

i really need some advice on calculating the right amount of wattage it would take up if i replace my current cpu with a x2 4400+

Forgot where the link is... sorry.

However, IMO it should be plenty enough.
The x2 4400 is 65W.

No it's not. You are confusing the AM2 Athlon 64 TDP with the S939 power consumption. TDP measure the amount of heat the CPU will generate.

Yeah. sorry.
Looks like it starts showing that I had no sleep today... damn those exams.

Anyway, I still think it should be enough, if it does deliver 480Ws stably.

According to Xbitlabs' actual power measurment, the S939 Athlon 64 X2 3800+ consumes 60w of power, and the S939 X2 4800+ consumes 96w of power. Assuming a linear increase in with respect to the model numbers the estimated power consumption for X2 CPUs should be as follows:

X2 4000 (if it existed)..........67.2w
X2 4200..............................74.4w
X2 4400..............................81.6w
X2 4600..............................88.8w

Also, according to Xbitlabs' GPU power consumption measurement, the X800GTO consumes about 49w of power.

If you are overclocking then the CPU & GPU will consume more power. How much? That depends on how hard you are pushing them.

Your power consumption with non-overclocked components should be as follows (this is off of the 12v rail):

CPU.........................82w
GPU.........................49w
Motherboard.............20w
4 Sticks of RAM.........20w (not positive if RAM feeds off of the 12v rail)
Sound Card..............10w
Hard Drive................48w (16w for each)
DVD Drive................32w (16w for each)
2 120mm fans............12w
Floppy........................0w (I think this feeds off of the 5v rail)
USB devices...............0w (I think this feeds off of the 5v rail)

Total Est. Power........273w (Overclocking excluded)

The 480w PSU should be enough for your PC. Check the sticker on your PSU to be safe. Look at the total amps on the 12v rail(s), if it is at least 25 amps then you will be fine. If you want to overclock the PC you should have at least 30 amps to be on the safe side.

Excellent analysis, mon!

Headroom is good, don't scrimp on the PS.

if he has a generic PSU then it will be an issue
