Excellent product
Product quality is good. working fine. It comes with a 16A male power card as default. make sure you have a 5A thick standard power cable to support the loads. Otherwise, plan to use with a 16A power inlet. i am using a UPS so used 5A good guage cable as power cord. Rest all are as advertised. Pictures also accurate.

Regret Buying Online – Corsair CX550 PSU
The product seemed fine on paper, but the service experience ruined everything. I purchased the Corsair CX550 PSU online, and within days, it started having power issues. The system wouldn’t even turn on. I contacted support, sent warranty emails, and even reached out to the service center—but still no proper response. Traveling all the way to Jabalpur for service is a hassle, and I’ve already lost valuable time and work. If I had bought it offline, I might’ve gotten a quick replacement. For creative work and business, this delay is proving to be very costly. Didn’t expect this from a brand like Corsair. The after-sales support is extremely disappointing. What’s the point of buying online if the service is this slow and unreliable?
