Upgrade Power Supply HP 590-p0071

HP Recommended
Pavilion 590-p0071
Microsoft Windows 10 (64-bit)

I am planning to purchase a Sapphire Pulse RX 5600 XT BE GPU for the Pavilion 590-p0071, which will require an upgraded PSU in the 500-550 watt range. I am not able to determine a replacement PSU that will fit and have the proper cabling. It appears that the original PSU is proprietary. (If so, this is the last HP PC I will ever buy.)

 

Can someone recommend a replacement PSU? Thank you!

its custom on most.

not some, like  400 G3

some HP  and adapter cable works,  to real PSU.

ive done few but not all , impossible. for me. to .

the gaming PC OMEN some do some don;t  some are 8pin or 2x4 wired, to 8.

Best is build your own PC,  use ASUS or Gigabyte, MoBo ,  and any PSU you waNT. OR GPU  , On my z270 , with 700watt DPS PSU, tested over 25cards, even 250w crazy fast GPU.

 

most scary on yours is this junk.  MAJOR alien this , no adapters  sold like on other simple 4/8 pin models.

i have dell XPS8900 with huge PSU and HUGE HOT FAST GPU.

but dells business grade desktops do not allow ATX PSU but adaptors super easy to use and buy. source

 

pretty much all there is ,is here.

I know DELL way better but these can work too just like the DELLs, but  getting the  right one is tricky

some HP I see have odd voltage for standby just like dell does.  +5Vstandby  ATX is alien is +12vdc-stby.  see blister mid cable bingo DC to DC amp chip . there.

 

im sure others have messed around here, and hope you get solid advice.

some PSU have a FAN command pin white-red stripe.

some HP pinouts told here  very good
