TDP of my sys

i3 2100 with 1 cpu fan (included on chipset)
Corsair 4GB DDR3 1333MHz (1 stick)
Sapphire 5670 1GB GDDR5 with 1 gpu fan (included on chipset)
Hitachi 1 TB HDD @7200RPM SATA 3GB/s
DVD/CD Combo Drive

what are the minimum and advisable TDP ratings of this configuration?

    I think the i3 2100 has a 95W TDP.

    The 5670 has a TDP of around 60W

    The rest doesnt really matter.

    If you are talking about power draw - Any 350W or higher PSU from Antec, Corsair, Seasonic or similar well known brand with 80+ Efficiency will power the system. I reccomend a 400Watt PSU just incase.
  2. The ATI website says that the full system with a 5670 in it should have a 400w PSU in it approximately.

    If you just want to know what PSU to get for it, one of these would be fine
    XFX 450w
    Antec EarthWatts 380w
    Antec EarthWatts 430w

    I would get the first of those if it were me.

    If you want a very in depth analysis for each of those things and exact numbers, perhaps someone else might be interested in assisting with that.

    Motherboard 50 W–75 W Depends on the number of integrated components.

    Processor 25 W–150 W For each physical processor (not cores). Most are 50 W–100 W.

    RAM 5 W–15 W For each module (DIMM).

    Integrated video 5 W–15 W Integrated into the North Bridge chip (Ed.: Though, increasingly on the CPU).

    Discrete video card 25 W–300 W For each video card.

    PCI card 5 W–15 W For each nonvideo card.

    PCIe card 10 W–25 W For each nonvideo card.

    Hard disk drive 15 W–30 W For each drive. Power use increased during startup.

    Optical drive 15 W–35 W For each drive.

    Cooling fan 3 W–5 W For each fan.

    USB/FireWire 2 W–5 W For each used port.

    With 9.5 jonnyguru rated PSU's available for $60-$65 I really can't see the sense in getting anything smaller. PSU's hit peak efficiency at 50% if ya save $8 on the purchase, you'll get that back in electricity savings. That doesn't mean buy a 1200 watter when ya need a 650 as that's not a small price increase but in the smaller sizes, it's just not worth the savings, at least if limiting the search to quality units.
  4. can i use UMAX Livewire USMPS 450W

    its +12VDC is rated 10A/25A
  5. Use one of the ones I mentioned instead.

    Those 3 are perfectly top of the line and help you avoid a lot of hard to diagnose problems that only exist with sucky PSUs.
