dz68zv only boots with certain power supplies

hello,

i am pretty knowledgeable with computer hw/sw but this has me stumped;

i have a new dz68zv mb and some spare parts that i want to setup as my updated music collection rig (ripping/converting/file modifying via audacity) ;

2500k cpu.

xfx 260gtx gpu.

2-4GB ripjaw dimms in the blue dual channel slots.

creative extreme gamer s.c.

small ocz vertex2 60GB ssd for o.s. / wd 640GB black for 380GB of music files.

that i initially thought was dead (hard cleared cmos/single dimm/ etc. etc.) but when i tried a different power supply it booted right up.

i flashed the latest bios and the board functions properly w/ w7 (i hate how intel tied o.c.'ing to speedstep but that is an issue that cannot be fixed).

turns out that this board will only work with certain power supplies, i only had 4 known working modern ps's at my disposal all are atx12v 2.2 w/8-pin /24 pin board connections and work in other modern intel chipset mb's.

2- corsair hx650w that allow the board to function normally.

1- power pc&cooling 750W silencer - onboard power button led lights up- on/off 1 sec. board acts like it is dead.

1- corsair tx520w- onboard power button led lights up- on/off 1 sec. board acts like it is dead.

only thing i can guess is bios based power saving/sleep/standby/wake issues that can only be fixed with a bios update.

a hard cleared cmos which forces settings to default should allow any quality modern power supply to function.

what am i missing?

thank you for the reply,

i have only the one board, all 4 power supplies are a newer spec than the minimum atx12v 2.0 as you linked for the board.

it has been working fine with the corsair tx650w so i am not going to get it replaced.

it is just so bizarre an issue, one i have never ran into before.
