What is a great PSU upgrade for a HP Envy 750-114?

HP Recommended
HP Envy 750-114
Microsoft Windows 10 (64-bit)

I have an HP Envy 750-114 Desktop and need to replace the 300W PSU with an upgrade to a more powerful one.


I have a NVIDIA GeForce GTX970 GDDR5 192 Bit PCI-Express Video Graphics Card 1GB HDMI.  It has a 6 pin plug into the card that splits into 2 4 pin with 3 wires on each.  I know the card is great but needs more power that the PSU does not have.  Plus the 2 4 pin ends have no where to go.  Please help me out.  Not sure what the factory board and take also.


Thank you.

Dear Rallychez,

 Go into purchase parts and service - on the HP main site - then enter your computer detail or get HP site to auto-detect it. Once it does and shows your options/choices, select the spare parts and service listing.

 Once there, look for your CPU (Main Processor Chip) - then look at upgrades of that chip. Look closely at the code for your/higher CPUs ... towards the end you will see a power rating: ***W


 Now go down to power supplies for Computers/CPU's first matching yours - then the PSU for the higher power CPU units ... specifically looking for those designated 430>460 Watt (325 would be enough from what you same, but 430/460 are the most used/common general standard for DT's /higher power graphics DT's.). Look at and write-down the HP (genuine) part number ... then go to the online pricing section or call a local HP agent/dealer/shop on line.


 Madness? Some of my dual Xeon servers run dual 1200 W power supplies, and I expect there are bigger units ... only you need special dedicated power supply (home or office) fused circuits [10>15 Amp ... Domestic/office are 8Amp] before you try turning them on.


 For you 430>460 will work great/more than enough - including future CPU upgrade if you decide to do that too. Plenty in reserve/never need another upgrade.

I understand but also can't find what you are telling me.  Is there a measurement size I need to go by to replace or is there a replacement that HP has that will work and fix in the computer? 


HP website tells me I have: 300 W uATX aPFC internal power supply

I know I need at least 400 W.

I want to make sure it will not over power the motherboard as well.

Thank you again.
