Can 370W power supply power this system?

    while waiting for an expert advise, why don't you checkout Antec's power calculator.
  2. It would be fine for that build. You will need an a PCIe adapter for that PSU though, your GPU should have been shipped with one. It will be 2 -4 pin molex to a 6 pin PCIe plug.
  3. If it were mine, i'd feel more comfortable with at least a 500-watt power supply, more headroom for the future. But since you mentioned the PSU is old, i guess that would do for the meantime, unless it starts giving you problems soon.
  4. Although you can run that systen with a 370watt psu,I recommend a 550watt psu or greater.The system will strain that psu quite a bit and you'll likely have to replace it in a few months at most.Not to mention that when a psu goes,it can take other components with it,including the motherboard.In the end this costs you more money.I always go with a higher watt and higher amp psu to increase the psu life,and not risk killing other hardware.Goodluck.

  5. And don't forget to look for reliable brands and models with active PFC and 80+ certification (the lowest level is OK)
  6. Best answer
    The 27 amp 12 volt rail will be more than adequate for your system.

    I estimate power usage:
    CPU - about 8 amps @12 volts
    GPU - 5 amps @ 12 volts
    MB - no more than 2 amps (outside of the CPU, motherboards don't use much 12 volt power
    1 HD & 1 optical - no more than 3 amps @ 12 volts
    fans - unless you have a lot, 1 amp @ 12 volts.

    That's less than 20 amps @ 12 volts = 240 watts max

    RAM - about 6 amps @ 3.3 volts
    Motherboard logic - 4 amps @ 5 volts
    2 drives logic - no more than 3 amps @ 3.3 volts
    Subtotal here - no more than 55 watts.

    Total power consumption, less than 300 watts.

    I over estimated in a few places. Murphy needs his share.
  7. As people have already said, you should be fine. That is a high quality psu. If you were trying to use a crappy brand psu, then the answer would be no. I use a 380W Antec Earthwatts in a system with a X2 4200+ and a 9600GSO 384mb both overclocked and it runs great.
  8. That PSU will be fine. However, if you plan to upgrade your video in the future I would seriously invest in maybe a nice 550W PSU just to ensure you have the juice to run a nice card if you choose. It's better to spend $30-$50 more now than spend $80-$100 for another PSU and have this one laying around. Just a thought.
  9. You'll be fine so long as you don't run prime 95 and furmark at the same time to see how much juice the whole things sucks up :D. I would still recommend you get a more powerful unit later, as you will be stressing your current one, especially if you want to put a more powerful GPU.
