I'm new to this whole upgrading GPU so could someone help me to see if I need to upgrade my PSU as well?
I have a Dell -
Intel Core i5-2400, 3.1GHz, VT-x, 95W Optiplex 390 / 4GB DDR3 RAM

I just purchased an ASUS Geforce GTX 650 video card and on the box it says "minimum 400W system power supply (with a minimum 12V current rating of 20A)" recommended. It only takes up one PCIe slot and it says "only motherboard power needed" on the box.

My PSU says it's Dell and model # is L265AM-00 / PN is 053N4
Input 100-240V ~/ 5A 50~60Hz
I was told that my PSU wattage is 285watts by Dell Tech Support.

Do I need to purchase a PSU that's higher than 400W? or is what I have good enough (I'm a bit confused since the 400W was a "recommended" requirement).

I primarily use the PC for gaming & internet.

Any advice would be greatly appreicated.

Thank you in advance!

tell us +12v ratings of your psu sticker

Is this what you need?

+12VA == 17A max
+12VB == 9A max
+5V == 13A max
+3.3V == 10A max
-12V == 0.5A max
+5V(FP) == 4A max

your psu is fine as gtx 650 uses 64w at max load and your psu has enough amperage ratings.

Thanks for the reply. I run dolphin and PCX2 on the PC and I heard it can be quite demanding.
Would running such applications be okay? I have no other hardware attached to the PC except for USB wireless keyboard+mouse and bluetooth dongle.
Thank you!
