Anyway To Deduct The Amount Of Wattage?

[Nic0s411]

Hi, I just figured out what was wrong with my build ive been asking a lot about: PSU was only 600 Watts, Graphics Card Used 500 Watts, Rest Used 77 Watts. So it came to only 23 watts to power it all. So what I did to check it was right was i took my graphics card out. It worked...but is there anyway I can deduct Used Watts without changing any parts? Heres my build:

Everything there is correct besides the case. I got the HAF something...Idk. They sent me the wrong case so I dont know much about it. Anyway, If anyone knowws the answer, please let me know ASAP!

Anyone got any ideas? 😀

it does have 2 120 MM fans...Would 1 Keep this from over heating??????

You could undervolt the Cpu and Gfx card to reduce power consumption, performance will go down as well though,
but the best option is to get a beefier Psu in there, and the more fans the better in my mind, removing one won't alter the powerdraw much

Most graphics cards do not use 500W. Even most Keppler cards are rated at about 225 - 275W. GPU manufacturers tend to grossly overestimate their cards' power requirements. For a 7850 - a 550W or 600W will be more than enough.

Alright thanks. What im going to try to do until i get the money for a new one is im going to leave the case OPEN, with 1 EXTERNAL fan running on a wall-plug. Hopefully itll work!

I tried it with the PSU and the Video Card in and it wouldnt Boot Up...when i took it out it did so...

I'd recommend contacting your PSU manufacturer - sounds like you got a bad one.

It cant be bad because it works without the video card....if it was bad it wouldnt work...

It can still be bad. What if it's only able to output 200W instead of its 600W rating???

BTW, just to make sure the basics are covered, did you plug in the 6-pin external power into the video card?

The 6-Pin PCI Express? Yep

What gfx card do you have? My guess is you have looked at the manufacturers recommended psu wattage whih is for the whole system. No single card pulls that power today.

I agree it could be a faulty psu, but it maybe not booting for other reasons besides power. Could be a bad gfx card...

Also, when you say th CPU is 77w, u would rarely get to that under gaming. In basic terms tdp indicates the max thermal power the cooling system needs to be able to remove.
