Will my Power Supply be enough?!?

Recommended Posts

Posted (edited) · Original PosterOP

(edit at bottom) I currently am in the process of making my new build, it consist of a B450M PRO 4, Ryzen 5 3600, GeForce RTX 2060 6gb, Seagate Barracuda 2tb 7200 RPM Hard Drive, HP EX920 256gb SSD, GSkill (2x8) 16gb DDR4 3000, 4 fans and then a Cougar VTX 450W 80+ Bronze power supply. On PcPartPicker it runs at 329W so I think I should be fine but I would like some opinions. Was reading the 2060's box while I wait 3 days for everything else and it said 500w power supply minimum, im fairly new to PC building as this is my second build. I will also be running 4 120mm case fans. (edit: Thank you for the quick feedback! Ive already ordered a 600w EVGA 80+ and I plan on returning my 450w to Newegg :D)

It's good practice to have a 150W+ buffer above what your system uses, I'd go for a 550W+ unit.

you should be perfectly fine, its not like you have a intel cpu using 125w. ryzen 5 2600 and 3600 dont really use that much wattage.


but it never hurts to have a better psu to help future proof yourself.

450w is plenty. usually your usage while playing or working is 2/3 or 3/4 of the recommended wattage.


be sure to get good 450w unit like cx/cxm 450w. or something from atliest tier B on our psu tier list posted above.

That power supply is VERY low quality. Replace it asap as it is a fire hazard

450W would be enough, but the particular PSU you have isn't all too great.

I'd suggest replacing it in favour of a CX450/CX550 or a TX550M.
