I have a 9500 GT which i want to upgrade to a Sapphire HD 7750.
I also have an unknown brand PSU which says max 400w.
I was wondering if my PSU could run my new graphic card without damaging my computer. Just for your info the 9500 GT apparently uses 50w and the 7750 uses 55w according to hwcompare.com and I've been able to run the 9500 GT without problems.
Intel Core 2 Quad Q8300 @ 2.5 Ghz
