My Dad, in an effort to fix a flakey FDD controller, decided to ditch his first-gen p4 motherboard (it's the only p4 board I've ever seen that can take either SDRAM or DDR RAM) in favor of a IS7-V.
He bought a prebuilt system from a place online and has some crap powersupply (it's "300watts" but there's no 4pin connector for 12v)
We put the IS7-V in, connected ram, cpu, and video card, but got no video or beeps from the system.
I tried the standard tests for that situation (clear cmos, reseat ram, tried different ram (known-good and new sticks), build system outside of the case to check for shorts, etc) and at no time got a beep from the system.
It obviously wasn't going to work, and we're looking at a minimum 5 day wait for parts from Newegg, so we put the old board back in (which is working fine now).
I suspect its his powersupply, we're going to order an enermax for the system. The lack of the 4-pin connector bothers me, but the other board worked fine without one (MB didn't even have the connecter). I'd just like some other opinions so I can feel OK telling him it's just the PS and when the new one comes in he won't have any trouble installing it.

Most mobos that have a receptacle for the ATX12V plug need it to power the CPU power circuitry, and won't run without it.
