Upgrading CPU, do i need a new power supply?

[SteveJKnight]

Hi guys, so basically i am swapping out my old Pentium G620 for an i5 3570 next week and i was wondering if i would need to upgrade my power supply? I won't be using a gpu for a few months, and when i do i will upgrade my psu. However, would my current 305w psu be enough for an i5 3570 with just integrated graphics? My Pentium runs fine, but the i5 3570 is 12w higher at 77w in terms of its tdp.

you'll be fine. just upgrade when you get a gpu since you'll have no choice then.

Yeah, i was planning on getting a GTX 750ti which is obviously low power due to the Maxwell chip. The psu i was looking at getting was the xfx 550w core edition.
