HP makes one that is specific to their cases and 400W gold. It is standard for the Envy and Pavillion cases that are the same form factor as this. They DO NOT use standard connectors, so if you want a third party product, make sure it is fully compatible before you buy.
Sorry, there was a problem. Please try again later.HP models based on the same size case, and shipping with discrete graphics, have a 400W gold rated ps; versions using just the integrated graphics seem to have the same 180W ps that comes with this. I don't know if third party companies offer a compatible power supply, but these are NOT standard ATX connectors. HP made their connections proprietary. I will look it up later--I bought this box, it will arrive later this week. Once I have the part number for the ps that ships with it, I can check upgrades. Be advised though that this system has a B550A chipset; so it won't support PCIE 4.0. Which in turn means, SAM won't function, if it matters. For graphics and storage, the system is essentially a B450 refresh. This system's 4700G is essentially the same as a Ryzen 3700x in performance, but with Vega graphics. Seems to be a big jump in memory speed for the Vega cores, compared to the 3400G; I will know after I get it.
