I have an AMD FX 4170 on an ASRock PRO3 970 motherboard. Although I am looking to upgrade soon, for the time being, I will be using my current 300w PSU, which only has a single 4 pin connector. I am not going to be buying any adapters, since I will be buying a new PSU in the future anyways. Any thoughts? The full specs should be in the signature.

It won't be working with only one because this socket requires more power so you won't be able to boot ... also i don't expect a 300w to do the job lol


Hope it helps

Thanks for your time guys. I currently have it working with the 4 pin power lead for now, but for some extra stability for overclocking, I have ordered a CM 500w PSU, and I am also currently looking at a cooler. Anyways, the important thing is that it worked, and it is stable under many hours of Prime95. For those that are wondering what the specs are, here you go.

Case-Cooler Master Elite 334 NVIDIA Edition
Front Fan-Cooler Master Sickleflow Green
Rear Fan-Standard Cooler Master 120mm Fan
Side Panel Fan-Dynex 80mm Fan
Motherboard-ASRock Pro3 970 AM3+
CPU-AMD FX 4170 4.2ghz Zambezi
GPU-NVIDIA EVGA GEForce GT520 (2gb, SC edition)
RAM-8 GB (4x2) Corsair Value Select Memory @1333 MHZ
ODD-LG SuperMulti 22x DVD Writer
SSD-ADATA S510 120gb SSD
HDD-WD Caviar 7200RPM 250gb
PSU-Previously a 300w PSU, soon to be a Cooler Master Extreme Power PLUS 500w PSU

Yet again, thanks for your help, and just so you know, some parts are much older than others and are subject to change at any point in time.
