Alright, so I bought myself a BFG GeForce 6200 OC 256MB DDR PCI Graphics Card because my Dell its pretty crappy. But it says it should have a 300W PSU. Alright, so I was thinking on buying a new one. Tried on newegg.com but they don't accept my credit card (motherfu...) so I went to an online store from my country (México).. and I found one, but it says it has a 20/24 pins connector and its for an ATX case, so I don't know what case do I have neither how many pins.
Can you guys help me?
