Old/Weak Power Supply Causing Unexpected Shutdowns?
My PC is unexpectedly shutting down during intense usage, such as
cranking out HD videos in Adobe Premiere Pro, and running BOINC projects at max CPU/GPU usage during the PC's idle time. Event Viewer doesn't tell me anything useful except for it being an unexpected shutdown. I've upgraded most of the hardware in the last 2 years except for the power supply, a Corsair HX520W.
(Note: No overclocking)
Motherboard: Gigabyte GA-990FXA-UD3 AM3+ AMD 990FX + SB950 SATA 6Gb/s USB 3.0 ATX
CPU: AMD FX-8150 Zambezi 8-Core 3.6GHz Socket AM3+ 125W
RAM: Corsair Vengeance 16GB (4 x 4GB) 240-Pin SDRAM DDR3 1600 (PC3 12800)
PSU: Corsair HX520W 520W ATX12V v2.2 and EPS12V 2.91 SLI CrossFire 80 PLUS
GPU: Gigabyte GV-R775OC-2GI AMD Radeon HD 7750 2GB GDDR3 VGA/2DVI/HDMI PCI-Express
Internal SSD: Samsung 840 Series MZ-7TD120BW 2.5" 120GB SATA III
External HDD: Seagate Backup Plus Slim 2TB USB 3.0
BD Drive: LG WH14NS40 14x SATA Blu-ray Internal Rewriter
OS: Windows 7 Ultimate SP1
If I remember correctly, the minimum PSU requirement for the video card is 400W. Is it time I upgraded the PSU? If so, should I stick with Corsair and look at models in the 750W range? Thanks!

520 watts would be plenty for that build but it may be faulty or warn out
