    Intel D945GCLF2 & M1-ATX

    Hi all,

    I have a question. Do somebody use this configuration as described in the title?
    I think the current of 2.0A (2.5V peak < 60 sec) should be sufficient for this Intel board.

    For your information:

    I bought a M1-ATX DC/DC. It seems to be OK. The overall current current consumption is arround 2A. Max. Peak current (with an IDE CD-Rom drive) is about 4.4A (<15s).

    At the moment I think this M1-ATX is sufficient.

    the "overall current consumption" is irrelevant. you need to look at the current consumption on individual voltage rails to determine if the PSU is sufficient. each voltage rail has its own maximum current output.

    the M1 can only supply 2A on the +12v rail. I doubt this will be enough for your setup.

    your PATA CD-rom drive will draw most of it's power from the +12v rail. a 3.5" desktop HDD draws about 2A from the +12v rail (a 2.5" laptop HDD draws from the +5v rail). the CD-rom and HDD alone could max out the M1's +12v rail.

    out of curiosity, why did you buy an M1-ATX (12v@2A) when the M2-ATX-HV (12v@7A) is the same price?

    I didn't think it would work because the Intel requires the P4 connector. The M1's manual specifically says that it should not be used with this type of computer.

    You're right. But with my setup, I have an average current of about 2A + 200mA.
    My setup: Board, 2,5" HDD @ SATA port, 3 external USB devices (one 2,5" HDD, 1 Bluetooth-Stick & 1 WLAN-Stick, ).
    I average ~2A -> 12V rail has an consumption <<2A

    Yep, and a maximum current of 2.5A (for maximum time of 60s)

    That's true. But I don't use this kind of configuration.

    My problem: First inform, then buy
    I bought everything (board & M1-ATX) without reading each manual online.
    Getting the hardware, I saw the mistake, P4 connector and the question to me, are the 2A @12V rail enough...?
    To the price: right, but not in Germany Here we have a different of about 35$ between the "cheap" M1 & the M2.

    I assembled the cable by myself. Anyway, you can buy such a cable, Power connector for 3.5" devices to P4 mainboard connector.

    I have a D945GCLF2 board with the M1-ATX. I went with it over the M2-ATX because the M1 has a higher 5V rail limit (10 vs 8). I have a bunch of USB devices, and only the LCD and the board use the 12V rail.

    I had no problems during in-home testing. However, it won't survive engine crank if the PC is already up and running.

    I just recently read about not using this on boards with the P4 connector because of V(core). I have no idea what this is. I bought my barebone system from Chris @ Mo-Co-So, who sent me the M1 with a Molex-to-P4 cable.
    Thanks!

    vcore is voltage (v) supplied to cpu (core)

    D945GCLF2 will tell u your vcore in the bios and CPU-Z is a free tool to tell u everything u need to know about your system in real-time including vcore. i also recommend speedfan

    D945GCLF2 is what im using and it says Vcore=1.153 right now but as operating temps increase i think it reduces Mhz, vcore, and fsb (i think fsb) dynamically to reduce heat/noise and maintain reliability

    i was *told* by the seller that the M1 has no issues with the atoms vcore. but its not recommended for much more (thats why its not generally sold with the p4 connector). but thats third person info too...

    i went with the m2 for the extra over head in watts always means less stress for the psu

    im sure a lil diging and you can find the info on the m1 that u need or just contact the seller.
