PSU Problem

I am thinking of upgrading. The Mbd I wish to get is the new MSI mbd with the new Intel Chipset support DDR2 memory as well. MSI recommends a 350W PSU. I currently have a Delta 350W PSU. If I upgrade will I need a stronger PSU? I currently have the following devices connected to my pc:
1 X Seagate 7200RPM 8MB Cache 160Gig HDD
1 X WD 120Gig 7200RPM, 8MB Cache HDD
1 X Segate 80Gig 7200RPM, 8MB Cache HDD
1 X CD Writer
2 X External USB Devices
1 X ATI Radeon 9800 Pro
1 X 17" Monitor
Please advise...............

  1. I couldn't find statistics for your power supply. If your PSU has decent power ratings, you should be ok, but if it is a cheaper PSU, it may be questionable.

    Look on the side of your PSU, there should be amp ratings for each of the different voltages. (EX: 12v+ : 16a )

    Try and find these, and we can give you a more definite answer.

  2. Input( 115V /8A, 220-230V / 4A )
    Output: 350W MAX
    +12V = 18A
    -12V = 0.8A
    +5V = 30A
    +5VSB = 2A
    +3.3V = 28A
    -5V = 0.3A

    I connected my new drive last nite. The pc just kept on restarting about thrice before I could log in.

  3. I can already tell you your P/S is insufficient.

    Input your components at the website below it will automatically calculate your needs.

  4. You PSU is plenty of power. Don't worry about the watts rating you will be more concerned with amps, as your extra stuff is all running for the 12+ line generally.

    I am running a 2800+ XP (OC 2.6 ghz), 6800 GeForce (Also OC), 2x512 MB RAM, all my PCIs are filled, two CD drives, equalizer, two hard drives, floppy, plus 6 case fans running 4000 RPM (This isn't counting the CPU, NB, PSU, GPU, fans), plus a hard drive cooler for each drive, and a neon light. All this is running off of 18 amps with no problems

    People put to much faith in watts rating. Now don't misunderstand me, watts are important, but not always the most important.

    Watts are nothing more than the combined figure of your amps and volts, if you have a bunch of amps on a voltage rail that you don't need, you aren't gaining anythign with more watts.

    I wouldn't worrym if I can run my system off of a very similar PSU, you shouldn't have any problems.

    Sorry, I didn't see that part before I posted, if you problems continue, it may be your PSU not supplying enough power. Strange though that I can run my system off of similar power though.

  6. It seems to be fine now. A bit off the topic (apologies to anyone that gets po'd). My new 160G Drive only picked up as a 130G. BIOS never updated..PC Normally restarts when connecting a new device. All I can say is Willamete sucks.. Will mess around tonight again. It takes about 206 minutes to copy 5 - 10 gigs of data from my old 120G to the 160G drive. AARRGGGHHHHHHHHHHH

  7. You've done a wonderful thing here today my friend. Saved many a noob a lot of money, time and niggling questions. Thanks..

    Da Worfster...

    They say I need 374 Watts. Thank goodness I'm running an Antec Neopower 480!!!!

    If you don't stand for something, you'll fall for anything.
  8. Kind of strange that a new MSI board won't recognize the full 160 gigs. You can partition it and should be able to use the full amount.

    As for the long transfer times, are your hard drives on the same channel, or are these two on seperate channels? Also make sure your drives aren't stuck in ATA33 or anything, and I am assuming you are using new 80 pin cables, and not the really old 40 pins?

    Since everything is fine, I wouldn't worry about the PSU, you system should draw similar power to mine, if not less, and I haven't expeirenced any problems. People rely to much on watts, and your watt rating can be inflated simply by putting extra watts where you don't need them.

  9. Also make sure you have the latest BIOS update for your motherboard.
