I have a question...
So i watched a video on a 400$ gaming PC build and in it was a XFX Radeon 7770 and a power supply that delivered 430W when i went to look for the graphics card on newegg it said i should have a power supply with a minimum of 450W. The guy in the video definetely looked like he knew what he was talking about and i just wanted to know if the 430W power supply would work with the graphics card or do i have to upgrade it to a 500W?
Sorry if this may be a stupid question but i pretty knew to all this PC stuff
Oh and also im using these parts in a gaming computer
You don't HAVE to upgrade the power supply, however it is HIGHLY recommended that you do so. The graphics card itself uses less than 200W. The only reason that they suggest you to use a 450W power supply is to have room to power all your other components as well.
Personally, I would highly recommend the upgrade for 3 reasons:
1) Building a system and then having the power supply not be able to power it is AWFUL. Just means you have to pay more money and wait longer to have it replaced.
2) A 500W PSU is only a few dollars more than a 430W one, well worth the difference for the added security
3) If you ever get a more powerful card, you will DEFINITELY need more than 430W to run safely.
Overall, it is just a better idea to spend a little more now on a better power supply than to end up having to buy 2 supplies.
