Question:

Is it ok to have only one power supply cable in the motherboard?

Hi, Im building a computer and my Power supply dosent have enough Cables/wires for all the slots. We do have enough to fill one motherboard power slot and we also have enough to fill about a hal of one. Can my computer run with just half of one of the slots? Also, my computer's Graphics card, a Gigabyte GV-N560UD-1GI nVidia GeForce 560 Ti, has two power slots, and the wires that it comes with have 2 4 pin peripheral power cables brnching off of it. My power supply only has enough to fill 1 of the cables. My dad says it will be fine but i dunno. Please awnser quickly! Any awnsers will be much a preiciated

Answer:

I'm sorry but no you need to have all the correct plugs installed if you expect them to run correctly. You didn't really give any info about the power supply but for that graphics card you generally want between 550-600 watt power supply to run anyways. Sounds like you will either need the proper adapters or another power supply altogether.
for the GTX560 Ti Here is what your APEVIA ATX-TL450W 450 Watts has: Those are for your motherboard: 1 x Main connector (20Pin / 24 Pin) 1 x 12V(4Pin) Those are for SATA and Molex HDD, DVD 3 x peripheral (aka Molex 4 pin) 1 x SATA Plus 1 x Floppy which no one uses anymore Your only solution would be to buy a newer, better power supply, which is what I recommend. Or, as a compromise (not recommended, as your power is not big enough for all components). Use 2 Molex to PCI-e cable adapters to power your graphics card. Use 1 Molex to SATA to power your DVD drive Use the only SATA to power your hard drive. Good luck.
