I bought a 4890 and I dont think my psu has all the connectors that i need. The XFX 4890 need 6pin and an 8pin . I unfortanately only have 2x6pin and a 4pin available which cant work. Can I buy any adapters ? If not, whats a good 40$ psu that definitely has these cables. Switching psu is a last resort!!!!

Can you send me a link to an adapter ? Plus I wanted something like 580W if anything, just for future references.

Do they sell the adapter at bestbuy, frys, walmart ? Whats a good psu brand for future references ? I want to buy one in 6months. & whats a good cheap brand ?
