Is 430W enough?

[Synergy_Nova]

So recently im going to be building a pc, i already have the case and the psu, but i feel like i have made a mistake getting a 430w power supply. On pc part picker it says that my system will be using 79-328W So im wondering if that is enough for my build.

Don't get a CX, 430W would be ok, But and its a big BUT, you'll really struggle to upgrade without changing the PSU. So putting an extra £10-20 in now will save you 50-60 in the future, and give you a better supply in general.

All good. If you have a smallish case then modular will help with cable management.

Generally it is good practice to use a power supply capable of delivering at least 500W when using a discreet video card. However, I think you will be safe with 430W, though that's starting to cut it close.

tier 2 500W is minimum for that GPU.
tier 3 550W.
