GPU on Pavilion Slimline S5-1110

Hi, 

What is the best GPU I can put into this desktop. It has the Sandy Bridge CPU but integrated graphics is too weak for me.

Greetings,

Welcome to the forum.

I am not a HP employee.

You have some graphics card upgrade roadblocks:

A Legacy BIOS, and 

A 220 watt power supply. You may have to upgrade the PSU.

Some Slimline PCs only accept single slot graphics cards.

Your PC's motherboard looks like it can do a dual slot graphics card. But there may be chassis' limitations.

Nvidia 600 series graphics cards or lower series Nvidia products would be a good fit. AMD graphics cards usually draw more power and require higher wattage power supplies.

This is all I can tell you.

Thank you for your reply. I have the ability to take up two slots, but they must be SFF slots. 

Also, my computer is capable of booting Windows 10 in either UEFI mode OR legacy mode (i made two separate HDD installs and confirmed this by looking up the system information page in the OS). Does that make any difference regarding newer graphics cards? or am I still limited by the fact that my bios/motherboard is too old. 

Also, do you think that this 220W PSU can supply up to 75W via the PCIE slot? Did HP make higher rated PSU with the same physical dimensions?

Hi Max,

You're very welcome.

You need a UEFI BIOS to run newer graphics cards.

Windows 10 shows the BIOS Mode as UEFI when you use GPT vs MBR installation method.

Your BIOS would have to have the following options  (Link) to successfully install a newer model graphics card.

Your PC's Slim form factor PSU dimensions are (7.9 x 3.3 x 2.1 inches). A standard ATX PSU dimensions are 5.9 inches, 3.9 inches, 5.5 inches. Small form factor PSU dimensions are 5.0 inches, 2.56 inches, 4.0 inches.

I don't know if HP makes higher wattage Slim form factor power supplies. HP is not providing PSU replacement part purchase options for this PC anymore. You can check at HP Part Surfer (Link).

A 220 watt power supply should be able to provide 75 watts to PCIe slots on the 12 volt rail. Check the amperage details on the HP power supply.
