Is there any way to calculate how much power is my pc using (in watts)?

[Rujdaga]

Hello fellas! Is there any way to see how much power my pc uses/consumes without that wattmeter or smth? my pc specs are

8gb ddr3, hd 7770 asus ghz, fx 6100, gigabyte ga-78lmt-s2p motherboard, 1 120gb ssd, 1 250gb hdd, and i have a 550w power supply (some swiss one, have it for a couple of years, never had problems with it) and im planning on getting a gtx 770 idk will my power supply be able to handle it.

Put the parts into PCPartPicker and it will give you an estimation of how much they're likely to draw.

Most of the power supply calculators are garbage. Admittedly, it's not entirely their fault, as all they really have to work with is TDP and TDP is virtually meaningless. Your best bet is to get a monitoring tool like HWINFO64, put your PC under various types of load, and add up the wattage you see there. Or, if you happen to have a UPS with an LCD display, it will tell you the total draw there. Not a bad investment to make in general, if you don't have one currently.

A UPS that has a display is always a good option for a multitude of reasons, including current flow.

If you wish not to opt for that, a less expensive option would be a watt meter. Kill A Watt is a common one.

It will allow you to see, in real time, how much power you're currently drawing in various states (idle, light load, heavy load, synthetic benches, power virus, ETC)

Power calculators should be used for nothing more than a 50,000ft overview of the general area of what you should expect.

thanks guys, will try all em out!

pSu CaLcUlAtOrS are useless and overestimate by a ton. Outervision is famously useless, and PCPP also just uses arbitrary, and way to high wattages to estimate. E.g. you'll find that a normal motherboard draws 70W according to it, and that 3000 MHz DDR4 draws 7W per stick.

 

For a very basic estimate, just do GPU TDP + 100W. And even that is an overestimate. The GTX 770 is a 230W card, so expect the system to draw about 300-330W from the PSU under a gaming load.

What model is it? Using a PSU that claims to be 550W with a <200W system for years means absolutely nothing, and says absolutely nothing about the PSU.

I dont really know what model it is hahah
