I'm looking to upgrade the graphics card in my PC and I am just wondering whether my PSU is sufficient to power either an HD 7770 or a GTX 650.
My current PSU is an Aywun A1-3000 420W (the PC was built by a shop). Now I know that many of you will jump in and say that this PSU is a pile of crap and that it will explode etc etc, and I have read one person's story of this PSU failing on them, but they were using rather high end, power thirsty components (Core i7 CPU, GTX560, 8GB RAM, extra case fans etc).
My system is (minus graphics card):
AMD Athlon II X2 260 3.2GHz
ASRock N68-VS3 motherboard
4GB DDR3 RAM (single channel)
3x 500GB HDD's
LG DVDRW/CDRW combo drive
mATX case w/ one fan
As you can see it is very modest, and I have read that both of these graphics card are very conservative in their power consumption despite requiring a PCI power connector.
Your thoughts would be greatly appreciated
