What PSU will fit?

[JiggleMe]

Any suggestions on a PSU around 550w-650w that will fit in here? i currently have a 400w HP PSU, don't think it will handle a 3060 12gb RTX

@JiggleMe,

Welcome to our HP Community forum!

Actually, a 400-watt power supply can power an RTX 3060, as I successfully showed in one of my HP upgrade projects, an HP ProDesk 600 G4 MT: Solved: Upgrading to an HP ProDesk 600 G4 MT - HP Support Community - 8610054.

If, however, you want to upgrade your power supply, there is a compatible 500-watt power supply available with p/n: L05757-800.  You can purchase one of these 500-watt power supplies online, such as from this trusted eBay Seller: NEW Power Supply For HP PSU 500W - Envy 795-0003UR Desktop- L05757-800 | eBay.

There may be a compatible 550-watt (p/n: L75200-004) and even a 650-watt (p/n: L36049-003) power supply available, but I do not have HP confirmation.

Everything i've read says there's a decent chance to damage the components of the graphics card using a 400w PSU, thoughts?

@JiggleMe,

Not my experience, but let's discuss this.

Please provide a list (part numbers) of your powered PC components: CPU, RAM, drives, GPU, and let's see what power draw you can expect in your PC.

CPU - Ryzen 5 5600g with integrated graphics (SMVB-8906)
Ram - 2x16GB (32gb) 3200MHz DDR4 UDIMM, (Cruicial)
Drives - 256GB SSD, WDC pc SN530 SDBPNPZ-256g-1006 (internal).. External Samsung, PSSD T7 SCSI Disk 500gb.
GPU - AMD RX 5500
(i'm not a full tech guy so anything i'm missing please let me know)

@JiggleMe,

OK, here we go:

CPU - Ryzen 5 5600g: 65-watt

Ram - 2x16GB: 12-watt
Drives - 256GB SSD, WDC pc SN530 SDBPNPZ-256g-1006 (internal).. External Samsung, PSSD T7 SCSI Disk 500gb 30-watt
GPU - AMD RX 5500 110-watt

65+12+30+110=217-watt total

I would guesstimate that your system uses around 240-watt -something you could easily measure/verify by using a watt meter such as this one.

An RTX 3060 has a 170-watt TDP, thus your overall PC wattage usage would increase from 240-watt to about 300-watt, give or take.  As long as your system doesn't consume more than about 340-watt, your 400-watt power supply (assuming a low 80% efficiency) should have no problems whatsoever to power your system.

Thanks, i got the 3060 12gb OC. installed it yesterday, power connectors make it impossible to close the side panel, but so far so good, was able to run Black Ops 6 on Extreme Graphics settings compared to low on my RX 5500.

@JiggleMe,

Outstanding!

Perhaps a 90-degree PCIe 8-pin power adapter may work to make the side panel close: Amazon.com : gpu pcie 8-pin 90 degree power adapter.
