How to measure actual Watt usage..?

[lunajun]

Hello people!
I recently built my first own gaming PC. It was great for first 3 months, until it makes random reboots in middle of the games. ( games like SC2, diablo 3 or lol).. I searched many forums and I found out it might be my PSU problem. Since, i am a Computer Noob, i need a help to find how much watt usage for my computer.. Since, i am a foreigner, i have limited English skills. Here is my SPEC...

AMD FX-4100 quade core processor 3.62 GHz - CPU

Hi - really isn't necessary, your cx500 psu is normally enough to power
a rig with a hd 6850gpu. Maybe you go a bad one.
750w is overkill, won't do any harm, but will cost you
more money than you need to pay.

Look for a quality 550-600w if you're concerned with a 500 being
not enough.

Stay with brands such as Seasonic, Antec, XFX, Corsair,
Silverstone.

what you have right now should be fine, but if i was ever to purchase a psu, it would never be the corsair cx series. they are low quality compared to other units from xfx that are made by seasonic and perform much better

With the good PSU that you have, I doubt that is your problem with the re-booting issue. It may be you have a defective motherboard.

(darn, can't edit)
If you want to check actual wattage used, pick up a Kill-a-watt meter. It will read total watts from the primary side of the PSU. Your actual system will be slight lower. There is now a UK version: http://www.amazon.co.uk/Plug-In-Power-and-Energy-Monitor/dp/B000Q7PJGW/ref=sr_1_1?s=computers&ie=UTF8&qid=1362969631&sr=1-1
