I want to know if the dell vostro 260 has it
Power supply . yes it has one PCI-E slot , no it does not nave one PCI_E cable - no not that either I am guessing you want to know if you can install a graphics card for gaming? the answer is NO
No, lower wattage PSU (typically less than 400 watts) generally do not ace PCI-E power cables as PSU's with that low a wattage typically aren't used in gaming PCs. The Vostro 260 came with a 300 watt PSU and almost certainly does not have a PCI-E power cable. Contrary to what Peter suggests. That computer does have a PCI-E slot. If you have a the mini-tower case you can fit a full sized discrete video card. If you have the SFF case then you're limited to low profile cards, and the PSU is a non-standard sized 250 watt unit. You're probably going to have to upgrade the PSU if you want to get new video card. Also, at best this computer has a Sandy Bridge i5 CPU, with the Pentium and i3 being more common. If you have the Pentium or i3 CPU, then you're only going to want mid-range or cheaper video card, as anything faster than say a GTX 1050 / GTX 960 or Radeon RX 470 or R9 380 will be bottlenecked by the older CPU.
