Does anyone know if there is a way to upgrade the psu for the 660s version. I dont care if the psu wont fit in the case I can work around that. I know on most motherboards they have a setting that can be changed to allow more wattage but some dont. The motherboard Dell ID number is 478VN. 220W is what I have now. I want a 300W to handle a mild graphics card.
I have found nothing online so far and Dell support seems to not want to release that info.
Since Slim version can accept only low profile card SAPPHIRE 100357LP Radeon HD 7750 1GB 128-bit GDDR5 http://www.newegg.com/Product/Product.aspx?Item=N82E16814202002
will work on your power supply, PSU upgrade is not necessary.
Anything else I can help you with?
