Re: PSU Antec NEO ECO 520C 520W RT This power supply was purchased through Newegg.com on 5 August 2010. It was installed into an Antec 200 Case in the same month. It has operated flawlessly until 1 November 2010. At that time the computer was online and running until it suddenly switched off. There were no power surges or any other irregularities. This computer containing the above mentioned Antec PSU has been plugged into an APC Backup-UPS 1500 which is in perfect working order to this day. In fact it is running another Antec build with an Antec 550 W PSU which is in perfect running condition. When I found that the computer containing the 520 W PSU powered off I tried to start it but there was no response. I replaced the 520 W PSU with an Antec 380 W PSU NEO ECO unit which started the PC immediately. I can only conclude that the 520 W power supply is faulty and needs to be replaced without charge to me with an equal or similar PSU. The 520 W PSU does not respond at all. The fan does not run nor is it capable of running at all. Thank you for your prompt remedy to this problem. Kenneth Johnston, [email protected] 530-283-9036 199 Shelley Lane, Apt. A Quincy, CA 95971
