Question

Recently purchased a XION II Gamers Case ATX (Green) and it came with a450 watt power supply that has already went out on me. Thats kindaweird because I only bought it 3 months ago and I'm rarly on mycomputer. This power supply should last at least a year, not 3 months.I was wondering if theres anything that can be done about this. Pleaselet me know
