How to find out the wattage of my PC? Solved

Question

Hello
I need to change my graphics card, but I've been told to know the wattage in relation to the power of the graphics card I like! However, I can't find any wattage mentioned on the computer, only volts!

Configuration: Windows XP Firefox 2.0.0.11

tribun · Accepted Answer

In electricity,  Watt = Volt X Amp  2200 W = 220 Volt X 10 Amp, and vice versa!  220 Volt = 2200 Watt / 10 Amp!  10 Amp = 2200 W / 220 V  If I'm not mistaken!   Hello!

normally it's indicated on the power supply of your PC, so on a tower, at the top, where the power cord connects to the PC.

nicobluesman · Answer

well, nothing written  just the volts...   :-(

u-boulet · Answer

Yes, it’s required that both the voltage and the power in watts are indicated, take another look :)

okidoki · Answer

Otherwise, you can open the panel of your PC normally (it's safe if you just unscrew and look) you should find a label located on the power supply (so in the top left).

pere noel · Answer

slut,

the label is probably located on one side of the power supply unit inside; either you remove one side of the case to see it, or else remove the 4 screws to extract the unit for a better check.

happy holidays...

okidoki · Answer

uh I have some doubts 2200 is a bit much the average is between 300 and 1000

epango · Answer

Hi,

To determine the power of your PC's power supply, there's only one solution: open your PC case. The power in watts (W) is written on the power supply unit. Sometimes, this information is not shown on a visible side of the power supply, so you may need to disassemble it to see the markings. It's not difficult; the unit is held in place by screws that simply need to be removed. If the power is below 350W, it would be better to replace your power supply with one of at least 400W.

Best regards.

okidoki · Answer

I do not question the principles of electricity calculation, but just the fact that the question is to know the power of its power supply, so for that normally no calculation is needed, it is indicated on one of the faces of its power supply. As for the values I mentioned, they are values that can be found with manufacturers (at least the maximum on rue Mongallet is 1200 W).

nicobluesman · Answer

output 250 watts max?  Is that it? That's not much! I had to unscrew it.

okidoki · Answer

It looks a lot like it, when was your PC from? Was it a custom-built PC?
If you need to change your graphics card, you might want to consider a new power supply between 350 and 400 watts as Epango mentioned in the previous post.

pere noel · Answer

LOL !! A PC power supply, for example:

a 400 W one means it provides 400 W, but it does not mean it consumes 400 W.

It is powered by 220 V alternating current and redistributes it as 12 V-5 V direct current.

epango · Answer

Hello,

A power supply does not create energy. For it to provide energy to the various components, it must take it from somewhere. Here from the EDF network (so it has to consume, lol!). The more energy it can draw, the more it can supply at continuous voltages of 12V or 5V, considering that the efficiency may vary. The best power supplies can achieve an efficiency of 80%. So the more it consumes, the more it can potentially power energy-hungry components.

Best regards.

mama2008 · Answer

You need to know, first of all, about VOLTS and also WATTS,

wherever you are, you should be in your room or dining room, it doesn't matter, it's not the kitchen and you're fine there because the energy that goes to the kitchen is 10 times higher than that of the bedrooms and living rooms,

it’s 10 amps to 20 amps,

so if a light bulb doesn’t blow in a year, it’s because you are indeed on 230 volts, which is our current voltage, and yes, in '48 it was 110 volts,

a light bulb = 25 w to 60 w 100 w

you cannot have equivalents for radios, TVs, all systems included in just one room!

your equivalents imply that your PC is old, but I have one, because the new ones use more electricity, so I calculated that you should be around 300 w

the calculation is that your room should not exceed 1000 to 1500 watts; you need to balance the rooms before equipping YOUR PC or COMPUTER

Hi,  He seems to be talking nonsense, with his "48=110Volts"!  See you soon  --  You don't put down horses, even when they become too old.

But come on Epango, you're silly! 3=2, that's well known  ; ) --  We all can make mistakes, that's why there are erasers at the end of pencils.

tribun · Answer

it's the same everywhere, when we exceed the possibilities, it blows!

a 10 amp fuse, overloaded, heats up and blows

same goes for a PC, when we exceed the established limits, it heats up, and then it crashes!

vapydark · Answer

for your info:

a Seasonic M12 700 watts is 80Plus certified and typically offers an efficiency greater than 80%, meaning that for 400 watts consumed at 230V, it can deliver 320 watts on its 3.3V, 5V, and 12V lines.

nicobluesman · Answer

thank you for everything

makav3lik · Answer

Salut mec, les watts marqués sur ton alimentation, il faut que tu ouvres ton ordi et que tu vérifies sur ton alimentation, parce que si tu veux te mettre une 8800GT comme carte vidéo, ça tire du jus, genre 450 watts à peu près.

epango · Answer

Hi,  230V is the nominal operating voltage. If you had read the comments, you would have known how to find out the power in watts (W) of your power supply. You need to open the case: the power is written on the power supply unit.  See you soon  --  We don't put down horses, even if they have become too old.

Hi,  Can you make an effort to write in understandable language? We don't always have the time to decipher this kind of language.  See you later  --  We don't put down horses, even when they have become too old.

rata · Answer

I said that I wanted to buy a 8800 GT but I only have 300 watts. I was told minimum 450 watts, is it really necessary?

u-boulet · Answer

For those who will have more courage than me: "I was saying that I wanted to buy an 8800 GT but I only have 300 watts, I was told at least 450 watts, is it really useful?" Give in French: I was saying that I wanted to buy an 8800GT but I only have a 300W power supply. I was told at least 450W, is it really useful?  We should think about spending more time in school, it gets tiring in the long run :-\ -- Say, will you be my friend?

epango · Answer

Hi,  You probably have a branded PC. The power supply is calculated to support just the components that are originally there. If you add something that consumes a bit more, you risk having problems. In the end, you do what you want.  See you!  --  We do not put down horses, even if they have become too old.

I would like to know if my power supply would support the configuration of my new PC: CPU P4 3Ghz Graphics card: Gforce 6200 HDD: Maxtor 500 GB IDE and 250 GB SATA DVD Reader/Burner Philips Motherboard: Gygabite RAM: 1GB DDR1 400MHZ My case has 350 W  Thank you in advance

tribun · Answer

hi a power supply supports the pc hardware, but everything we add (peripherals or otherwise) decreases the voltage, causing problems! if I draw too much current on my electric meter, the fuses will blow! it's the same for a pc!!!!!!! (= problems)   (example) for USB ports! a solution is here!( regulate the power supply)  http://www.presence-pc.com/actualite/hub-usb-trust-22916/

matman2099 · Answer

If you buy a Gforce 8800, make sure that your power supply provides enough amperage on the 12V rail.  I have a BFG 8800 GT OC and according to the specs, it draws 28A. Calculate a good 15A for the motherboard and if you have fans and all the extras, that will give you the number of amperes you need on the 12V.  Also, be careful that the 12V is divided in two; it might not be good.  I believe you can find a 500W that should be able to give you a good 50A on the 12V.   Example (my machine) mb = Asus M2N-MX SE cpu = AMD Athlon 64 X2 5600+ (2.8GHz) mem = OCZ DDR2 1G 800MHz cg = GeForce BFG 8800GT OC 512MB DDR3 (28A) cooling cpu = Zalman 9500 (6W) cooling case = 5X 80mm fans (1.2W) power = Ultra ConnectX3 600W (12V output 35A)  I am too tight on amperes; I can see through a program from my motherboard the voltage variations. When I'm gaming, I have a massive voltage drop: 11.93 at idle and 11.62 at full load. I am looking for a new power supply to fix this problem before I damage it.

matman2099 · Answer

not very complicated, I've found the company I want to have as a power supply.  Enermax is among the best.   Recommended model   Infiniti 650W (12v1 = 28A, 12v2 = 28A, 12v3 = 30A / total of 52A max) or 720W (12v1 = 28A, 12v2 = 28A, 12v3 = 30A / total of 56A max) (plus, when you shut down your computer, it spins the fans for cooling for a few minutes)   The 650 is about 150, and the 720 is 250.   I currently have the 720 on order.

rainbows67 · Answer

Bonjour, I wanted to know how to see the power of the power supply (for a graphics card). Of course, I've read the information but when I open the PC, there’s nothing described, so where is it on the other side? And I don't have the keys to open it :s or how else can I do it? Thank you.

electricien · Answer

First of all, your motherboard supports no more than 300 watts... If not, there's a risk of instability for electronic components and failure (motherboard out of service). Good luck with the troubleshooting... Brand + model / connection on the manufacturer's website / read the manual. Graphics card / brand + model / connection on the manufacturer's website / read documentation amperage voltage (power) It's up to you to find the mathematical formula to determine the power "watts."
