How much is enough power supply for this build?

Solution
yea with your 4830 that sounds like a fairly classic sign of maybe the power wasn't sufficient.

But yes pretty much that is what I am saying. Try the card, even if it fails, it shouldn't damage the card by getting insufficient power. Think of it this way, too much power can fry cards, but too little it just won't work. Worst which could happen is you are without a card or without computer until a better power supply comes in.

The bigger things you need to make sure is that you have the right PCI-E power connections for the graphics card. If you do, you might be alright. AMD graphics cards are based on RISC technology, like in your smart phone but different. So while they can use a lot of power, they are fairly low power usage for the...


Thank you, I've experienced that issue several years ago with my HIS ICEQ 4830 card when playing heavy graphic game, sometime screen goes blue, sometime it freezes. I don't really know if it's because VGA or my power supply. I can't even figure it out until now. That's the reason I don't have a confident to buy a new card. But if you say that's it's might not causing a big harm so I might as well try it. Even if something goes wrong I can still buy a new power supply right?

i buy a lot of used Video cards. One thing most people neglect is efficiency. There are good gpu's out there that don't use a lot of power. There are those that use tons of power. Good thing is to always carefully check the power needs of a gpu before buying. Even if you have a big enough power supply, power hungry gpu's also get very hot, generally dont last very long before they burn out and generally make lots of noise. Unless I would get a really really good deal on a power hungry gpu, i stay away from them.
