“Are you saying definitively a standard-sized ATX power supply can't be used to have a better video card other than something similar to a Radeon 550? HP's site indicates: "One PCIe x16 socket (for discrete graphic card)." That implies no limitation.”

Yes, I say definitively, categorically, absolutely, without a doubt, the HP Pavilion TP01-0034 does NOT provide an ATX format power supply in the stock configuration. Nor will an ATX power supply readily fit into the chassis, mechanically or electrically, so the stock configuration cannot be readily upgraded to higher wattage. And by "ATX" I mean it will not fit ANY of the varieties of industry standard off-the-shelf PC power supply formats: ATX, SFX, Flex ATX, mini-ITX, TFX, etc. It is a physical format proprietary to HP that nobody else makes, is incompatible with everything prior, and which HP doesn't document, at least not yet. HP parts and documentation does not offer any power supply upgrades for their proprietary original part in this system, just an identical replacement part for failures. HP specs correctly state that the PCIe x16 socket will accept a "discrete graphic card". That compatibility is restricted to graphics cards that take power entirely from the PCIe connectors, even though HP doesn't explicitly state that restriction. HP should clearly disclose this restriction; they do not, but that doesn't mean that they're promising no restrictions. The stock system has no power supply unused capacity, and does not provide connectors, for the separate 12V power connections that most graphics cards require. A few lower-performance graphics cards like Radeon 550 types do not require separate 12V power connections, so these are eligible upgrade candidates for this system. The stock system provides a 180W power supply, which is already fully budgeted into running the CPU/motherboard, USB ports, upgrading PCIe cards, and upgrading M.2 or SATA drives. There is no spare capacity for any upgrade that demands additional power than these items. Of course if you're a tinkerer you could wrangle and splice-in any 12V power supply. You could fit it in the space available, or run power in from an external power supply outside the case. My point is that there is no *ready* way to upgrade this with an off-the-shelf power supply that just bolts on and plugs in. In that scenario you'd also be fussing with air circulation and adding fans. And worrying about whether your modifications are reversible or voiding the HP warranty. I'm not unhappy with the proprietary HP power supply. It is very efficient, compact, cooled, and quiet. The stock power supply runs the stock system fine, including my HDD drive upgrades. The case hardware is splendidly simple but effective. HP has well-done videos showing how to disassemble, repair, and install upgrades in the case. If HDD drives and PCIe cards are the only upgrades you'll need, this is an economical and high-quality design. I'm very happy with it because my application happens to fit those limitations, and it was a great bargain price of 500 bucks for Black Friday 2019. It makes a fine business or home computer with an i7 processor and built-in 4K UHD graphics. Just don't fool yourself that this is a mini-tower that you can plug in all sorts of power-demanding upgrades such as high-end gaming graphics cards, or that it is easy to work around this weakness of being non-standard in the power supply.
Sorry, there was a problem. Please try again later.I bought this computer knowing that the 180w proprietary PSU was insufficient to power the AMD Radeon 570 RX video card that I needed. A little research found that there are several different HP PSU 500w models with two 6 pin PCIe 12v power connectors + a two pin that allows one to be used as a 6+2 connection. I bought the HP L05757-800 from Impact Computers in Hollywood FL. It fit perfectly into the case and the MB connectors were exactly the same. Note: If your PCIe GPU has an 8 pin (6+2) power connection and comes with a 2 6 pin to 1 8 pin adapter - use it. The card (and the computer) will not start with the 6+2 connector. Another word of caution: You must boot the computer in safe mode and disable (not uninstall) the onboard integrated graphics. A final note: Sometimes the computer refuses to boot if I have a monitor on one of the display ports. It will boot with a monitor on the HDMI port and after it has booted will recognize the display ports (make sure the monitor supports hot plugging to a display port. All in all, more trouble than it was worth, but once I had it working it is perfect.
Sorry, there was a problem. Please try again later.Yes. The limitation is not the PCIe slot, the limitation is the power supply. Not good I know but that is what I have learned. You might be able to use an external video card but you will have to do some hacking to get another video card in. The wiring is not standard. jdr
