I need a 550 Watt Power Supply

[ParadoxFE]

Hello, I want to upgrade my PSU but I do not know any that are compatible with my computer. I really need a 550 Watt power supply for my graphic card. My computer is HP Pavillion 590-P0117CB.

@ParadoxFE,

Welcome to our HP User Forum!

Even though @Prométhée is technically correct, and most thoughtfully herds you within the serene safety of the HP Reservation, there are reliable and secure ways to go beyond a mere 500-watt power supply, but more about that in a moment. Your HP Pavilion 590-p0117cb (5QA45AA) has amazing Upgrade potential, by the way.  I have been looking into making a desktop platform like yours as my next legacy HP desktop upgrade project -but I digress.

For example, your Lincs motherboard (SSID: 843B) can be upgraded with an i7-9700 (3.00 GHz up to 4.70 GHz, 8 Cores, 8 Threads) and according to: CPU-Upgrade: Intel Core i7-9700 CPU possibly even an i7-9700K (95-watt TDP) or even an i9-9900 (same 65-watt TDP as your current processor), even though that is as of yet not entirely clear to me.

Anyway, please take a look at this HP Pavilion Desktop 590-p0xxx User performance benchmark: https://www.userbenchmark.com/UserRun/52957514, which shows your desktop fitted with a very respectable RTX 3060 Ti.  Now, according to: https://www.nvidia.com/en-us/geforce/graphics-cards/30-series/rtx-3060-3060ti/, this high-end graphics card requires a 600-watt minimum power supply.

I doubt very much this User underpowered this GPU/Gaming Rig with a 500-watt PSU. -So, how was it done?

Please take a look at my legacy HP Z240 SFF desktop upgrade project: Solved: Upgrading HP Z240 Desktop Workstation SFF - HP Support Community - 8427878.

DISCLAIMER: ANY (hardware) modifications shown in this link are not approved, endorsed, or recommended by HP.  Apply at your own risk.  And I would only recommend it for PC-savvy nerds with above average mechanical skills.  In short, you can sync ANY (<1,000 watt) ATX power supply with your desktop to power essentially any graphics card you can think of.  Either inside your PC case, or boldly parked outside.

Since your desktop is pretty spacious, you can probably find a high(er) wattage ATX power supply that fits inside your PC.  If not, park it outside.  To make this happen, you need an "ATX 24-Pin to SATA power supply adapter card", and if the GPU of your choice is too big to fit inside your chassis, you'll also need a "PCIe X16 to PCIe X16 extension cable/dock" and a graphics card base/stand.

Think about it. If interested, drop a line.

If @Prométhée's 500-watt power supply is all you really need, by all means, disregard my post.

Btw, you can purchase a 500-watt L05757-800 online, but they are a bit pricey: L05757-800 HP Gnrc Psu 500W Ent17 Fr Gld (encompass.com),  HP L05757-800: Search Result | eBay, or here, for example: L05757-800 original HP Desktop-PC power supply 500 Watt - sparepartworld.com.

Hope this was helpful.

Kind Regards,

hi I suggest you see the pros and cons anyway @ParadoxFE 
Even if the answer here from @NonSequitur777 , is interesting compared to the benchmark
see the prices..
To begin with, I answered your question simply, because you do not specify what you want to do!
your original configuration, if you haven't changed anything else, is quite light..
So I based myself only on the question, while waiting for you to answer, if you need more information
So, if we consider, that you need to install more memory
The original disk is an HDD, it would make more sense if you change the processor etc., to install an SSD
do a simple calculation
Intel Core i7-9700- €435 (we can find cheaper, but it doesn't matter)
Nvidia RTX 3060-Ti - €601 (also depending on model)
Samsung 970 Evo NVMe PCIe M.2 500GB-€86 (same thing)
500-watt L05757-800 more or less 170€
with just this, you arrive in 1290€
(price in euros, since based on the benchmark site)
For not much more expensive, you can have an equivalent configuration, see more powerful, and recent!
So, to see, either you do the minimum, while waiting for .. just to boost it a little, or it will be more advantageous to buy a more efficient machine, for practically the same price

and you can find other models of this type, at hp or not!

@ParadoxFE,

Btw, one of the best graphics cards you can power with a 500-watt L05757-800 power supply would be something like the RTX 2060 -not the "Super" version, as that card requires at least a 550 to 600 watt power supply.

Yes indeed @ParadoxFE  

you can try, some manufacturers, like Asus, have a filter that allows you to check what is possible in relation to its power supply
