I have a computer and I want to get a second video card, but I am unsure which new card my PSU can handle. The components in my computer that take draw significant power are:
Nvidia 560 ti video card
intel 2600k processor
16 gigabytes of ram
1 hard drive
To power this I have a Antec 620 watt psu (48 amps on the +12v rails) that is about a year old now. The card I might be getting will likely be a radeon 7970 or 7950.
I recall checking that 2 560 ti cards could run on this psu, and power consumption seems to be 7950 < 560ti < 7970.
If I would rather avoid getting a new power supply, can I add one of those cards to my current computer build?
@cbrunnem I use linux, so it is easier to get them running together.
@daswilhelm I don't have much money, and gaming cards are faster at rendering (gpgpu) than most workstation cards with cycles. OpenGL is way faster on workstation cards, but I don't care about that much for what I need.
I know of people who successfully use a set up like what I am proposing, I just need to know if the psu can power the cards.
