Radeon 5850 and a standard Dell Precision 390?

Will a radeon 5850 work in a Dell Precision 390 2.13ghz, 2 GB Ram with standard power supply?

I currently have a Radeon 5770 in there but would like to upgrade it.

Thanks

    no, the PSU does not meet the requirements of the GPU, 375 watt PSU won't cut it but 500W would and you will get extra watt headroom also. If you are willing to spend an extra $50 on a decent PSU you can make the upgrade.

    Okay thanks very much!

    How easy is it to change the PSU, Is it a straight forward job?

    Also do you know if theres a certain type I need to buy to fit the Dell 390?
  3. nope, they are all ATX, but HP are known to have weird pin connections on their motherboards preventing any upgrade for a PSU.

    In order to upgrade your GPU, you'll need to upgrade the motherboard and PSU also, HP are bad like this. I can confirm that the PSU will fit and am happy to recommend a motherboard that'll work, as long as you will go with it.
  4. Okay thanks. It's a Dell that I've got not a HP.

    Why would I need to buy a new motherboard? (don't have much knowledge of this techy stuff)

    Thanks!

    Oops, I meant HP but Dell is also known for this (my bad, forgot it was a Dell). Could you check the pin power connection on your motherboard? I'll search it also to check if you aren't too sure.

    Okay thanks I'll take a look.
  7. Dell once had proprietary power connectors but that was like 10 years ago.

    Hi, Sorry for the mega late response!

    Just getting round to sorting this.

    Opened the machine up yesterday and gave it a good clean etc. The motherboard has a 24pin mains power and a 4 pin cpu power.

    I recently bought a fairly cheap CIT 750W PSU which I thought might work???

    Is this psu safe to put in the Dell precision 390?? Not going to fry the whole system is it?
  9. should not be a problem, go for it.

    Yep went for it. Old PSU took about half hour to take out and new PSU took about 10 minutes to put in.

    Then I put in my MSI Radeon 5850.

    Super quite and all running very nicely.

    Now doing a little AltCoin mining via IpoMiner multi pool, using GuiMiner-scrypt and getting around 325khs.
  11. great to know it works.
