My pc specs:AMD FX(tm)-8350 Eight-Core Processor
8.00 GB DDR3 ram 1333mhz
NVIDIA GeForce GTX 550 Ti
Asus m5a78l-usb motherboard
1TB Hard drive

I am having slight problems with this build but i think the power supply might be the problem the power supply is a casecom ATX 400w.
before i had the amd fx 8350 i had the fx4100 and had no problems with it so i just wanna be sure its the psu so i can get a new one and if it is the power supply that is causing the problems or you think it is please refer some good psu's for a decent price please help me with this thanks.

No, the PSU is not good enough. I would highly recommend a decent 500W PSU at least.

XFX, seasonic, antec or corsair are probably the best brands. I would certainly go with one of those.
Edit: this PSU is a good option: http://pcpartpicker.com/part/xfx-power-supply-p1550sxxb...

400W is a slighly low , but it doesnt mean is the psu..... and your new cpu d ont need more power to run , above all it was working before with fx-4100.

The new CPU does need more power to run. It consumes more energy.

1st problem i get ping spikes on 2 games and 2 games only CS:GO and TF2 any other game is fine but once i seen my 8350 spike to 100% cpu usage when playing CS:GO. another problem i have been having but hasn't came up in a while is random blue screens but i thank that was because i updated my bios. and it just feels like i am not getting enough power out of this system as it is a decent build.

i did a bit of research on this and there is only a 30wattage difference between the fx 4100 and the 8350 when under load so 30 watts cant be that much off a difference to cause problems now can it?
