Conclusion and Verdict
You may not always need huge wattages for your setup. So its great to see that power supplies come in so many different wattages. This saves you money and its great to know that when you have a specific budget to spend on a build you can squeeze every dime out of your part to achieve max performance to price ratios. That is where getting a power supply, that is at your recommended wattage, allows you to put that money into other areas. The P550B power supply is a great choice for anyone getting into computer building. This is a basic power supply but uses high quality parts. The P550B fan doesn’t feature a stop and the cables are not modular. The power supply is the motor of the system and most of the time you never even see it. Most builders try to hide the cabling even on the high end modular setups. So if you don’t need it don’t waste your money and put it into something else that will increase the performance of your system. Because having a 1000 Watt power supply when you only need 500 isn’t going to increase the performance of your system one one bit.
Now for the big question will this power supply power the new cards? No, the card you will max out at is the RTX 2080 and that’s cutting it close. Make sure you do your research and make sure you are able to meet the power requirements of your system when getting a new power supply.

One thing and the most important thing to remember when swapping out power supplies, IS NEVER REUSE CABLES FROM ANOTHER POWER SUPPLY! I would even caution this idea if its the same brand. I learned this the hard way in my past learning because I didn’t want to re-cable a case and come to find out some power supplies connectors vary brand to brand. Here is good explanation of what I am saying. Luckily when I did this I only lost some lights because the power supply was semi modular and that probably saved my mother board and CPU. Anyways take the time and use the cables that come with your power supply at all times!
