Installing by Radeon RX 550 causing HP Prodesk 600 g4 microtower not to display on the monitor

[Bvgo]

Hi,

I tried installing a new TRT Radeon Rx 550 graphics card on the PC, but when I turn it cause make a single beep and then doesn’t come ON on the monitor but the system and graphics card comes ON. I noticed this with their fans which keeps spinning. I’ve updated the bios but still nothing shows on the monitor.

when I removed the graphics card. Everyone’s works normal like new. 

PS: I also increased the RAM to 40 gb 

how do I resolve this. 

thanks

on average the AMD radeon rx 580 requires  a 500 watt power supply minimum

the HP prodesk 600 g2 has a stock 250 watt supply or a optional 400 watt unit (see the problem yet?)

this means you can only use a nvidia 1030/1050 card (250 watt supply) or up to a 1060 (400 watt supply)

you can buy a power adapter co enable use of a std ATX power supply this will require the power adapter AND A 550 WATT power supply

power adapter:

power supply: (stay with NAME BRAND pwr supply makers!!)

Okay, yea. Why didn’t they specify this at their documentation.

they do,..........where do you think i got the numbers from

HP quickspecs for prodesk 600 g2 microtower lists the power supply numbers 

https://www8.hp.com/h20195/v2/GetPDF.aspx/4AA6-1494EEE.pdf

amd lists the recommended wattage for the rx580

https://www.amd.com/en/products/graphics/radeon-rx-580

or a simple google query:

https://www.google.com/search?q=amd+radeon+rx580+wattage&rlz=1C1SQJL_enUS909US909&oq=amd+radeon+rx58...

seems to me it's you that didn't look that hard

My sincere apologies DGroves, I mixed up the numbers, it’s a Radeon rx 550 and no 580. I apologize for this mistake, this is AMD GPU. Thanks

nothing really changes, for the 550 (instead of the 580) as this card has a  400 watt recommendation  and as such is well over the ability of your current 250 watt supply
