Hi guys, I am fairly new to the PC community and so would like to ask for some help from the experts who are commonly found on Tom's Hardware.

I am looking to purchase a 2GB EVGA gtx 750 TI superclocked

(http://www.scan.co.uk/products/2gb-evga-gtx-750ti-sc-pc...)

however, I do not know whether my PSU is sufficient. I do not know how to read it, so I will list the details here for your expert eyes to survey.

+3.3V 16A MAX
+5V 20A MAX 120W MAX
----------------------- 450 W MAX
+12V1 18A MAX 500W(MAX.PEAK)
+12V2 16A MAX 360 MAX
-----------------------
+5V(SB) 2A MAX
-12V 0.3A MAX

Thank you guys

Arjan

In addition, it seems that this gpu only needs 300W supply, do I still need to upgrade, as that's pretty difficult at this point

GeForce GTX 750ti - 20A and a 400W PSU minimum

So in theory it is not sufficient, BUT the Ti draws all of its power through the PCI Express lane, so as long as your motherboard is drawing from both rails it should be fine. What type of motherboard do you have?

Personally I would upgrade the PSU as well since I am not a big fan of any PSU that's around and still uses multiple 12V rails
But budget is always an issue so lets see if it can work,
Also can you provide the Manufacturer and Series of the PSU to check against this list,
