Looking for a psu which is either 500 W or 550 W to fit in the HP Pavilion 550-252na Desktop PC

[Alex176]

First of all, I am looking to upgrade this pre-built pc with a Sapphire RX 580 Nitro+ 4 GB GDDR5 Samsung Memory/PCI Express 3.0 Graphics Card, however, I am unsure what PSU to buy due to the fact that the PSU will need to be a small one but with 500 W or 550 W. I have had a look myself, however, don't feel I can find a suitable product which was reliable and had good reviews please may I have some help? The current PSU size roughly is 14 x 13 x 9 I think I am not 100% sure. This is the PSU in the desktop currently: 180 W uATX Energy Star 6.0 internal power supply

PSU which I think will fit but I am unsure which is the best product to purchase:

Thank you for posting on the HP Support Community.

I see you need help in upgrading the Graphics Card, on HP Pavilion 550-252na Desktop PC. Don't worry as I have a few suggestions which should help you.

After reading your post, I did go through the Product specifications of your product and found that you have 180 W uATX Energy Star 6.0 internal power supply installed on the PC.  

To get the answer to this question, You can upgrade to the RX 580 Nitro but you'll need a power supply of 400 W or greater. An extra adapter is not required for the PSU but make sure you select the right form-factor. 

Hope this helps! Keep me posted for further assistance.
