Bigger power supply bad for my mobo?

I want to get a new power supply so I can upgrade my graphic card for a better one for gaming but I'm afraid my motherboard can't take it. I contacted Hp but they said the max is 400 watts but I want a 500+ watt but Hp is known for to not know questions so they guess. If you can look at my spec below to see what you guys think I would appricite it very much. I when I do put in a new power supply would i have to reset my Bios?

Thank you

More about bigger power supply mobo
  1. I'm not sure why HP would say no. My guess is they don't offer a PSU that large? You should be able to add whatever PSU you want. Don't worry about a big one frying your motherboard. A PSU will only deliver whatever power is asked of it. It won't supply the full ???W to the system.
  2. I was just asking if a 500+ PSU would hurt my motherboard and they said "It wouldn't change anything but it probley won't boot up" with that sentence they confuse me. They don't answer your questions exactly they just beat around the bush. I ask him why it would hurt and the response was " some coils might not handle it" so they said a 400 watt is the limit.
  3. My motherboard model is "Benicia-GL8E". I can't seem to change fan speeds with this model of mobo but my fan1 runs at 1540 rmp and fan2 935 rpm with my gpu at 50.C idle without playing games but goes to 60.C when playing world of warcraft. My cpu are core0: 38.C core1: 38.C idle without being on games but jump to high 40s when playing world of warcraft.
    Is this good or bad? my graphic card is a geforce 9500 gs.
  4. Coils won't handle it? Sounds like he is one of those guys who thinks the full 500W will be sent 100% of the time.

    High 40s under load is fine, most don't worry until you hit the 60s.
  5. Yea if it hits 60s thats when I will get a new HSF.
    I downloaded core temp, real temp and speedfan and they all read the same temp for GPU and CPU. The TJ Max is at 100 but my hardware diagnostic tool says my cpu temp is at 43 but i'm thinking thats my case temp because people said the sensor is on the other side of the Motherboard.
  6. I did clean my GPU fan couple days so it went from 51 to 48 but it only gets 48 if my room is cold lol

    These statements are made because they are supposed to only suggest things that they themselves sell as "good" for your system. Anything you do not buy from them is A: bad business for them, so B: it must be bad for you too.
    That is why you do not buy a prebuild system, and then call them when you want to start upgrading. Prebuilds are not meant to be upgraded. They WANT YOU TO BUY A NEW PC, not upgrade what you have. They don't make money by doing that. So they are never, ever going to give you good or correct upgrade advice. A tech that does, will not be employed by that particular company for very long.

    You can put a 1000 watt power supply in your system and it will make no difference. The parts on the board will only pull the amperage they need, the PSU does not "force" more into the parts or the board. The parts only pull what they need.

    Now, what DOES make a difference is you do things to the board that cause it to use more amps, like overclocking and upping the voltage on the memory, your CPU, your PCI buss, THEN the board may draw enough amps to physically burn out the capacitors. Maybe, but doubtful, because your board is not going to support the features you need to do this in the first place.

    If you just need a bigger PSU because you have done something like installed a high end GPU, there is no worries at all.
  8. I also have those same system specs and wanted to upgrade my GPU to something beefier.. So i bought an Asus EAH4890 DDR5 graphics card... knowing that the meesly 350w power supply wouldnt run it, I bought a 650 TRUEPOWER psu,, but unfortunately when I powered up the sytem, everything starting spooling up.. but no video.. both monitors read NO SIGNAL..

    I switched back to my Nvidia 9400GT and it also did the same thing...NO SIGNAL... only when I switched out the PSU back to the old 350w, did I finally get a picture with the old Video card...

    SO for some reason, The newer 650W PSU does not work with this system...

    Any suggestions?
