I'm going to buy a new graphics card. ATi 5670 512 GDDR5. I'm also buying a new PSU, because my 2 year old 300w Bestec won't be able to handle it. My question is - is a Fortron 400w PSU good for 5670? (Fortron FSP400-60APN 400W (80PLUS)/ ATX12V v2.3/ Silent 120mm FAN/ Active PFC PSU/ 3 SATA) It's 31$ in my country.
