I'm thinking of buying a new PC for my system, but I'm not sure whther I should pick modular or fixed cable (Corsair by the way) an I was just wondering if this would matter and also what kind of wattage my system would need if you can. My PC system specs as of now are:

GPU-Sapphire Radeon 7870 HD GHz Edition (2GB GDDR5)
CPU-FX 4130 3.8GHz (Zambezi)
MOBO-Biostar A960D+
PSU- Ace 500w
RAM-8gb DDR3 1333Mhz
HHD-Seagate 1TB

500w+ would be fine, but don't get the VS or CX series from Corsair, they are made with inferior parts. Stick to the AX/HX/GS/TX series.

Thanks, but there's a problem with the current PSU I have where I think it downclocks (if that's even a word) my CPU's speed, voltage and multiplier when under heavy load (during gaming) and I've tried every other liable option, but I think it the PSU not working efficiently enough or because its wattage is too low for my PC. What do you think?

The wattage of the power supply is fine, but the brand isn't good at all. It could be that it just isn't capable of delivering what it states, which wouldn't allow your components to get to full power, but that would generally result in a blue screen.

Your problem is likely just the 4130 not being good for gaming.

I'm thinking it's more of the bad PSU than the CPU. The FX 4130 is actually a quite capable CPU when gaming, but even in barebone environments it underclocks itself which I find to be extremely strange and can only point towards the PSU not delivering what it says on the box.

get a new PSU. Corsair CX series is fine for budget builds and your build fits that. With a decent overclock and a 7870 you should get good fps.

Are you overclocking? Do you have an aftermarket cooler?

The 4130 isn't really good for any game that requires a decent amount of CPU power.

If you're seeing downclocks, it's more likely the CPU/motherboard is overheating than the power supply not delivering enough power.

Trust me, I check the temps continuously when I'm playing my games and they always appear to be normal when the downclock happens and same goes with the motherboard and I'm running the Prime95 test with CPU-Z and CPUID right next to it and the CPU temp doesn't even go over 50 degrees and it is just downclocking itself from 3.8 GHz to 1.4 GHz. It must be the PSU then.

No I'm not overclocking and the cooler is a CoolerMaster one.

Can you try the program....Open Hardware Monitor? It measures temps as well as CPU Load and Power (Watts). I use this program so I can monitor and watch things during gaming. This way you could check the load. Usually in gaming I get up to 85% CPU usage but that is a i5.
