They have a very neat PSU calculator quide where you select your rig's components and the site tells you the system's power consumption. Quite useful I think.

P.S. This has also been mentioned in this month's CHIP magazine. Oh and there's a poll for which PSU brand you use - Enermax is second :heart: :heart:
 
neat!!! My system came upto 304 :P

But look at this.... I configured my dream system

FX-60, 1900XTX x 2 Crossfire, 2 DDR sticks, water cooling with Dangerden DD12V-D4, 2 SCSI 15K HDDs, 4 SATA HDDs, 1 floppy drive, 1 DVD-RW, 5 LED 120mm fans, 3 USB devices, one Soundblaster with front bay,

FX-60 oc'ed to 3.5ghz @ 1.6V

And result ??

736 WATTS!!!!

omg wtf!! my total wattage shown was around 535W and how come a 500w deliver tht!@ :O

First of all i don know how urs reached 535, mine's only 280 W :P And its peak usage, not avg. And also since urs is an Antec Neo HE right? So i guess its good enough to take it anyway
 
ok hers mine
Opteron dual core 165 as i will be using dc within a year.
@ sata hdd's
2 7200 ATA PATA hdd
dvd rw
cd rw
2 DDR ram sticks
Nvidia 6800Ultra
Sound Card
Modem 56k
and total set of high performance 6 fans as in P180.
Thats all and its around over 535w
 
by high performance they mean over 200CFM fans
Do you use more than 200CFM fans?? I doint think so... :P
 
Mine comes to around 494 Watts

@ X86,how come your came to 535 ?

Its coming to around 520W

And dude,how exactly are you going to fit 6 fans in P180 ??

P180 has 5 fans not 6.

6 is your total with the Proccy Fan.
 
its 181W !!! for my current rig.

ps: the figure that you get is the peak loads calculated, including taking for granted that all devices are running concurrently and consuming peak loads. but still multiply it by (square root of 2 = 1.42 x ur displayed value) to get the most optimum psu wattage.
for e.g. if the resulting figure is about 396W then
396 x 1.42 = approx 550W psu.
This will take care of losses due to decreased efficiency of the psu and give a reasonable cushion for peak transient / initial torque loads of the motors etc ....

NB: the actual wattage used by ur system will be far less then what is displayed. since not all devices will be running concurrently all the time. and the devices will not be running at 100% load all the time.

This is what puzzles most noobs .....actual usage is less than displayed but psu requirement is more than displayed......;)

Calculating the total wattage requirement for a psu is very similar to building a Dam or a Bridge. You always plan for the most extreme Conditions / values plus some more .....:D

Total 6 120 fans one on top one on back one on down and two infront hard disk cages and one on cpu hsf .
 
306 watts for my rig. I'm guessing I won't need to upgrade my PSU for some time at least. If I throw out my X850XT PE and add an X1900XT it becomes 353 watts. I'm still within safe limits!
