I purchased the phenom II BE 550, and one of the proper motherboards to unlock it. When it arrived, my psu had died so I had to RMA it. My backup only has the 20 & 4 pin connectors(OEM 300w), meanwhile the motherboard has the 20 pin and two 4 pin connectors. When I tried to unlock it, the pc seemed to boot but nothing appeared on the screen, basically like it was staying in sleep mode. I only had one 4 pin connector plugged in, so I wasn't sure if unlocking made the cpu a 120w from the 80w it started as in dual mode. I thought this might be why, although I know all of them don't unlock as they could be faulty cores. I don't care that much as I use it for gaming so it will be fine regardless, but figured I'd ask so I had an idea if it'd even be worth it when I get my 650w psu with the two 4 pin connectors back to attempt again. I thought it might be a lack of power as the motherboard can handle up to 140w but I imagine it requires the 20 and two 4 pin power connectors to all be plugged in, not just a single 4 pin. Any help would be appreciated, or advice. I'm using the correct bios just for a little extra info in case anyone thinks that that could be the issue.
