Should I just buy what I need, or spend more money to be future-proof? For instance, should I buy a more powerful power supply (for future-proof) or should I simply buy what I need? Things to consider: - If I buy just what I need, the price will be cheaper. Higher-watt power supply tends to be more expensive (small rise in watt, big rise in price). eg: 380W: US$61.3 430W: $70.7 500W: $87.4 550W: $101.5 650W: $121.2 - Every now and then new technology comes, new types of cables may be required. Then my power supply will die out. -- The workaround would be to use adapters. But are there any disadvantages/problems? Thanks.
