Help finding a new power supply.

[DBR-Evolution]

Hey,

 

I need some help finding a new power supply. Someone I know, who had also built his pc, gave me a Advance MPT-7500 750 watt power supply as a gift. I didn't got any problems with it until an update of BF4. Now my system starts shutting down whenever I crank games like BF4 or watch dogs up to maximum (didn't have the problem before said update)(when checking the logs I find this: Caused By Driver  : ntoskrnl.exe). Since the shutdowns first happened when playing BF4, I headed to their forum and asked there if someone could help me. A lot of people said it was my PSU so I did some background checking on my PSU. It turned out that there isn't any information available about this PSU. I'm really pissed now because my friend gave me a possible ticking time bomb.

 

So yeah, I need a new PSU, fast. 

 

My specs:

- Motherbord: Asrock Z77 Pro3​ 
- cpu: Intel Core i7 Ivy Bridge 3770K​ 
- gpu: AMD Sapphire Radeon Vapor-X Boost Edition​ 3GB 
- ram: Corsair and Kingston (2X4GB + 2X4GB) 
- cpu-cooler: Cooler Masters 
- ssd: Samsung 840 Series 120GB 
- hdd: Toshiba 2TB (7200 rpm) 
- dvd-drive: LG GH24NS95

Your Recommended Minimum Power Supply is 357W

I honestly don't think that the PSU is the problem here, it certainly is bad and needs an upgrade, well, do it first and then we can talk about fixing the problem.

What is your budget?
