If you’re working with an HP EliteDesk 800 G9 Small Form Factor (SFF) desktop and want to upgrade your graphics card, you might wonder if your power supply can handle a newer, more powerful card. The good news is that, with a few simple steps, you can make it work.
The power supply in this model is a 400-watt unit that comes with one PCIe 6-pin power cable. This cable can deliver up to 12 volts at 18 amps, which totals 216 watts of power. By using a PCIe 6-pin to PCIe 8-pin adapter cable, you can connect a compatible graphics card that requires an 8-pin power connection. For example, an adapter like this one bought on Amazon can help you make the connection.
One important thing to remember is that the size of the chassis limits which graphics cards you can install. The SFF case is designed for low-profile cards only. This means you cannot fit full-sized dual-fan cards inside. However, there are low-profile cards that are more powerful than standard models, and many have successfully been used with this setup.
For instance, you could use a low-profile variant of the NVIDIA RTX 4060 graphics card. These cards typically have a power requirement of around 115 watts, which the 400-watt power supply can comfortably support when paired with a quality 6-to-8 pin adapter. This makes it possible to upgrade to a decent gaming or graphics card without worrying about power issues.
In summary, to upgrade your graphics card in this computer, you should:
– Use a PCIe 6-pin to PCIe 8-pin adapter cable to connect your new low-profile graphics card.
– Confirm that the card is low-profile, so it physically fits in your case.
– Choose a card that has a power draw within the capacity of your power supply, such as the low-profile RTX 4060.
Following these steps, you can successfully upgrade your graphics card without needing to change your power supply or compromise on performance.
