Graphics Card

[Spaz009]

I have a HP Z420 work station that is using a ASUS graphics card (see picture below). I would like to install a Gigabyte GV-N250OC-1GI. 
There is a power supply and only 1 of the PCIe slots is in use and that would be

slot 1.  I’m pretty sure it will work, just not 100% sure. 
Also, once I’ve installed it, I’m not quite sure what needs to be done prior to turning on the PC, during booting, drivers???

@Spaz009 -- I’m not quite sure what needs to be done prior to turning on the PC, during booting, drivers???

Short answer: nothing.  Windows should detect the new adapter. Worst case is that Windows will use a "generic" device-driver, to give you 800-by-600 resolution. Then, download the manufacturer's device-driver,  and install it to get the "optimal" resolution that is compatible with your monitor.

hi

I would tell you to check. @Spaz009 
you indicate if I understood well that you want to install the two graphic cards, together?
If we look at the product page it is mentioned

https://support.hp.com/us-en/product/hp-z420-workstation/5225033/document/c03274125

600-W, 90% efficient power supply

is it  this ?

except if this is the card you are talking about, it says this

https://www.gigabyte.com/Graphics-Card/GV-N250OC-1GI-rev-20#ov

*Rating power 500W or greater system power supply*

both at the same time this may be insufficient in power supply

also see the different manuals available that could be very useful to you

No, I’m replacing what was in the desktop with a Gigabyte Graphic card. Just one card, not 2 b

Ok, so in this case it should be fine

but difficult to guarantee this
you have the drivers available from the link given so well this model
