HP DC5850 SFF - Finding the best GPU Upgrade with 240 Watt PSU - PCIe x16 2.0
I'm trying to find the best video card that can be used in this machine. I would prefer that it have at least 512 MB ram , Dual display capable (one vga and one hdmi - with or without using adapters) , Low Profile because this is a sff case ,

PSU: 240 Watt
Slot: PCIe 2.0 x16
Processor: AMD Phenom 8750B (3 core 2.4 ghz, 1.5 MB L2 Cache, 2MB Shared L3 cache, HT bus 3.0)
Memory: 6 GB (PC2-6400 800MHz)


Alternatively, I would like a link to where I can get a larger PSU for this sff as they are nearly impossible to find. (350 Watt or greater)

Had a computer similar to that one (BTX case *shivers*) and I stuck a Radeon 6570 in and it worked fine but that case is horrible if your GPU has a large heat sink (Such as a Passive cooled Geforce 210 like I did and it hit the bottom of the case)

My bad, I'm not even sure how I came up with the wrong specs when the PSU is correct, but the info still stands.

Were you interested in trying to run something with less power? The gt640 draws about 10w less. I dont know if its available in low profile.

These will work, I just dont know if your PSU can handle the load or for how long.
gt630 is approximately 40w
7750 is about 45-50w

manufacturers recommend more than you need because of several factors.
- PSU manufacturers often list peak power rather than continous power for their supplies.
- Its not advised to run a psu at 100% load for long periods.

I do not know how much power your system currently uses or if these cards will push you over the edge. I just dont know Dell that well. I had no problems running a 4670 (60w) card on an hp 250w PSU for my grandkids for about 4 years when I sold the system this past year and its still working today.


Considering you have a 65w dual core processor and mine had a 95w athlon2 x3 , I would hope you you could run it. Neither card needs external power, they are powered off the pcie bus.



This is an HP not Dell. and its a 95watt triple core (AMD Phenom 8750B)
I'm not sure where you got Dell or Dual core from but thank you for the info, I might try the GPU that only recommends a 300w psu

the best low profile card is probably an amd 7750 or a gt730. You will need to measure and make sure the card length will fit in your case.

the Power supply in that is a custom job and you wont find an aftermarket replacement sadly.



The 7750 recommends a 350 watt PSU and the gt730 recommends a 300 watt PSU. I only have a 240 watt PSU.

I'm also running 2 x 1TB hdds and a pci wifi card in this system
