so i must buy now antec neo 620w or my cooler master 460w is sufficient and not risky,
and what is the risks that could happen ?
What is the model number of your Cooler Master 460 Watt power supply unit?
Cooler Master Real Power Pro RS-460-ASAA-D3
Cooler Master Extreme Power Plus RS-460-PCAR-A3/-PCAP-A3
Cooler Master Extreme Power Plus RS-460-PMSR-A3/-PMSP-A3
Cooler Master Elite Power RS-460-PSAR-J3/-PSAP-J3
I know that the Extreme Power Plus Series and the Elite Power Series are known for not being able to deliver their labeled power. Also the DC Output quality from both of these series are not that good or very poor or even out of specification.
I also notice that none of these Cooler Master 460 Watt power supplies have at least two 6-pin PCI Express supplementary power connectors required by your graphics card.
With poor voltage regulation low voltages can cause instability and high voltages, over time, can damage hardware.
Unnecessary electrical noise and ripple can cause premature failure of sensitive components in a number of different PC subsystems.
