hi all
i want to calculate the exact other components power consumption if possible in order to calculate the total system power consumption under 100% load on cpu and gpu
and i can't determine the right total

is it cpu+gpu+other components =95+75+56 =226w ?
or like the web site calculator suggested =296w?
or maybe cpu+gpu+other components =95+75+100 =270w?

my calculation for other components power consumption :
-(mainboard chipset+ich10) use (22+6)=28 walt
-2 harddisks use 7+4=11 walt (i have checked the vendors pdf specs)
-any other fans use 6 walt
-DDR2 memory use around 8 walt (i have checked the vendors pdf specs)
-keyboard and mouse use 3 walt
so total power for other other components is around 56 Walt right?

-for reference the result of power calculator website for my pc is as the following
Load Wattage:296 W
+3.3V +5V +12V
9.5 A 14.0 A 20.3 A
102 W 244 W
Recommended PSU Wattage:346 W

my PC Specs are:
HEC 350W Power supply that have 12V rail ( 20A 276walt)
Q6600 G0 95w TDP at stock volt 1.2875V
graphic card that is 75w~80w TDP that take its power from mainboard no extra 6 pin required
mainboard gigabyte EP43-ds3l
8(2x4)GB DDR2 bus 800 at 1.88v
one harddisk wd blue 7200rpm sata
one harddisk wd green 5400rpm sata
one 120m Fan take its power from mainboard and cpu stock fan

Thanks on advance

^Agreed, no OCing. Also i wouldn't be happy running it in summer. Those calculators are estimates, there will be peaks and spikes. Also PSU's age, meaning that the amount they can effectively output safely drops, additionally the amount of power that they can safely convert from mains AC into DC changes with temperature. Hence there is no 'simple'answer.

Gut feel and rule of thumb says that you are right on the edge, and a gaming session on a warm day will tip you over it, this year or next year.

Why are you trying to calculate these things anyway? Are you selecting a new power supply, or maybe seeing if your existing power supply is capable enough? The online calculator you were looking at is probably just overestimating the power draw of those other components a bit to account for potential worst-case scenarios, since they don't know the exact power characteristics of every component. Also, some components, like hard drives, may momentarily draw more power when they are starting up, and need to spin up the disks. In any case, your 350 watt PSU will most likely have a decent amount of overhead for those components, and even meets their recommendation, so I don't really see what the issue is.

this is the web site i already used to calculate my total power in my question above so i don't get what you mean by your answer
i think you didn't read my question well 🙁
i want to know which is right calculation ? my calculation above or web site calculation (226w or 296 W) ?

on summer i use the air conditioner to cool my room during playing and use extra 2 fans for pc cooling :)
from your answer i think i got lucky and didn't damage my pc when i overclock to 3.2 without raising stock voltage that why i was hoping there is room for OC and i plan to upgrade my pc in future but its tempting to OC but it is risk

to aquielisunari
i have 20 A not 16 A for 12V rail
i wish i could get "Kill A Watt" device but i can't offered now

last(i wish) is there any hope/chance that my total system power is around 226w not 300w ! :)

Kill-a-watts are cool little devices, but might not be particularly good for this purpose. The power draw from the wall will be higher than what the components will actually be drawing from the PSU, since a power supply is not 100% efficient in converting AC power into the DC voltages that the components will use, and that level of efficiency can vary depending on the amount of load on the PSU. At 80% efficiency, for example, the Kill-a-watt might say that the computer is drawing 300 watts, when the components are actually only using around 240.
