hello all, I am from Bangladesh, here is my pc spec

Processor: AMD FX 8120 3.1 GHz, 16MB total Cache , 8 core processor 
mainboard: MSI AMD 970A G46
grapics : MSI NVDIA GT 630 2GB PCI Express
Ram : 8 GB ,3200 Bus Speed
Harddisk : Hitache 500GB 7200 RPM
Powersupply: Thermaltake 350W litepower

Not extreemly slow but I am not getting actual expectation speed on it , my intel i3 laptop is faster than it ...your valuable reply is expected 

Power Supply

 

I don't know what your slow at, but 350W, screams to me not enough amps. the GPU isn't much, but overall, the only thing that screams out to me that something is odd is, the power supply.

-------------------------

Actually I am getting slow performance at startup,shutdown , application actitivity , legs etc....and I am ensure you that is my fx 8120 is much slower than my i3 laptop

for your information I have noticed that

my CPU temp is : 72 degree

and Mainboard temp is : 30 degree 

(its winter here isgust 

Please check it

Again... your power supply. the CPU temp sounds high, very high, and that could be for a numer of reasons, the most viable is uneven power to the CPU, which... under-rated power supply. I'd go with a minimum of 500W, I'd recommned at least 600W. Not all about watts anymore, it's about amps.

-------------------------

suggest me a best power supply unit for my conf

please tell me what PSU is best for me

A SeaSonic or Enermax unit about 550w for peak efficiency.

Crosshair IV Formula, Phenom II x4 965 w/ Corsair H60, 8 GiB OCZ Platinum DDR3 1600, XFX HD 7970 Ghz, 512GB Vertex 4, 256GB Vector, 240GB Agility 3, Creative X-Fi Titanium w/ Creative Gigaworks S750, SeaSonic X750, HP ZR2440w, Win 7 Ultimate x64

 

I'm not familiar with the indian market availability, I know from past experience, you guys seem to be hit or miss on what may be available. Seasonic as mentioned, Thermaltake ToughPowers are good, Corsairs are good, andAntec Earthwatt series are good. I can't say with any certainty about enermax, but I almost always stick to the list above, hasn't treated me wrong yet.
