if not try something else , this model is made by AcBel Polytech and they are not good .
The problem is i bought it from 3 weeks ago and i cannot replace it sadly,i am gonna run it with msi gtx 970 but im afraid that it will fail and hurt my system.
Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Combined Continuous Power/Current Available on the +12V Rail(s) rated @ 45°C - 50°C ambient temperature, is the most important factor .
Your Psu with its maximum combined +12 Volt continuous current rating of 59.8 Amps and with two (6+2)-pin PCI Express supplementary power connectors, is more than sufficient to power your system configuration with a single GTX 970 card , so even with power drops it will not fail your system in any way
