1. The First thing you have to look at before buying a new Power Supply is that the Manufacturer. Always go with the reputed brand. Avoid cheap, generic power supplies.
2. If you are going for the 700W PSUs, then you must have known that these are very small as compared to normal ATX. So, size is also an important parameter to consider.
3. You should also check the PSU’s connectors to confirm the unit is compatible with your particular system. The term 20+4 pin refers to a connector that can function as either a 20-pin connector or a 24-pin connector.
