Hi guys,

So recently someone put up an ad for a used Corsair CX450M for the equivalent of about 30USD. Prior to knowing this information I wanted to go purchase a CX550M costing about 80USD locally. According to the seller, the CX450M has been used for about 3 years now, and the warranty is still on for about 2 years approximately. I'm going for a budget build so 50USD is quite a big difference.

My question is:
  1. Do you guys think its safe to purchase this second hand PSU?
  2. Will the PSU be sufficient for my build:
i3-101000f
1650super

Thanks
