I have been getting my system together for a couple days now but before I went ahead I wanted to know exactly how to wire it.
Pc built from a compaq presario 5000
1 ghz AMD Athlon Processor
256mb PC100 SDRAM (soon to be 512mb)
Geforce FX5200 128mb
This is what I have now but I plan on switching from IDE DVD drive to external usb slot load. also a USB hub with-GPS-heyboard...
anyway using the PSU Calculators around...I rated at 215w so does that mean I cant use the Opus or M2?
I mean I have seen others use them with much more powerful pcs...
Is it because theyre using mini mobo? I am using the motherboard from the presario so is that why?
anyway i figured I use an inverter but wasnt exactly sure as to how to wire everything so I drew this:
Im not exactly sure where to place relays/fuses so help me out.
PLEASE let me know if this is a correct and reliable way to go or tell me what to change.
(My plan is for the pc/screen to NOT turn on when I start the car, rather power run tru to a switch and then when I want flip the switch and the PC comes on. I plan on turning off the PC via START>shutdown everytime, then turn off car. Im not lazy and would rather turn it off like this everytime so I dont screw something up.)
I am a commuter college student so I drive to UNT(mean green) every day there and back so I want to use the PC on the long drives but driving around town where its only 5-10 min drives at the most the PC will not be in use and just my headunit.
come on guys 40 views and no replies? please someone help me out
Well, correct me if i'm wrong, but you have 12v wiring going from your inverter to your screen and PC? Don't you mean AC?
Hell, you're not going to play any newer games on a 1ghz athlonXP anyway. Use onboard video or get a lower-powere video card.
That one omission would likely get you within specs for the M2ATX.
If you're absolutely commiteted to that video card, there's always the Opus 250w PSU or the DSATX.
so would u recommend like a 64mb or 32mb video card?
also is my wiring diagram correct? i really dont want to fry something up
Your diagram is partially correct (you can consider it correct if.)
The wire from the inverter to the PC has to be a 3 prongs AC (standard computer power cord).
The screen is power by a wall plug that convert AC-DC which come with the screen (if you bought it that way.)
Okay now like DP said, get low power video card. I would recommend a GeForce MX400 or similar. Why? because my onboard video car is the MX chip .
If the Mobo is compartible with atx power supply, I would suggset you use DC-DC instead of inverter. DC-DC PSU of choice is DSATX or Opus. Those are rock solid unit and customer service is alway +++++++++++++++++.
what do u mean compartible? do u mean compatible? and how would i know if my mobo is compatible with atx
If the mobo is compatible, you can use aftermarket PSU and Antec or Thermostake. The reason I ask because if the mobo isn't ATX standard, you can't use one of those DC-DC PSU.
An example of that is some DELL computers isnt' ATX standard, thus, you can't buy off the shelf PSU and use on DELL computer.
