Power Consumption For Graphics Card

HR7 · Apr 2, 2014

Hi, i am about to buy a MSI R9 270X 2GB Gaming Graphics Card and it state that i need a minimum of 500W Power Supply.. I have a 500w PSU and my specs are as below :-

Asrock B85 Killer
4GBx2 Kingston HyperX RAM
500GB WD HDD
i3 4130 3.4ghz
DVD RW / DVD ROM
Sapphire HD6670 1GB

Do you think if i get the MSI does my rig will be stable with 500W of Power Supply?

Depends on what make/model power supply you have. Your system will only draw around 300-325w at peak load, so the wattage isn't of concern, but you want to make sure you have a quality power supply.

Yes 500Watts will be more than enough. Your gpu requires 400 at minimum with at least 17Amps of current @+12V rail. Everything is quite good with your setup and good to go

@HiTechObsessed I have the e-mag power supply

@brarboy are you sure?

I would recommend upgrading your power supply. In terms of watts, 500w is plenty for a 270x, but that power supply isn't very high quality, and isn't rated for stress.

HR7 :

yes i am sure you will be alright with normal loads just check the sticker once, see if +12V column has the value more than 17A? As i haven't heard about the brand you mentioned, i can't say about it's build quality.

Thank you guys.. So for this month do you think the Power supply could hold the graphics card for its factory clock? I would get a new power supply next month..

just don't do heavy load work for the time being until you get better psu. You will run ok till then

@brarboy how about gaming like battlefield 4 on ultra?

HR7 :

seriously? I would like you to hold your horses until you have better psu brand in you hand. Don't blow up your whole setup just due to psu.
