What Power Supply Should I Get?

ermopalpopcorn · May 23, 2018

My question is how many watts and what psu should i get. I just bought a ryzen 5 2600 using a ASRock A320M-DGS mobo and a rx 480. Right now my system runs fine with an i5 3450 and the rx480 with a 450 watt psu. So should i keep the psu or am i gonna have to do a little upgrade. Thanks!

450w should run your setup fine, you may want to upgrade it in the future but I don’t much incrrased power usage upgrading from your existing setup.

Depends on what 450W PSU you have right now. 450 W is enough, but it should be a good quality unit. If it's something like a VS450, I'd immediately buy a new and better unit, like the Corsair CX450.

What is the exact model of that PSU?

If you want get a good psu, 550w - 650w ( evga g3 650w, corsair rmx 650 both around 100 usd) are the range you are looking for, that should able able to handle any single core gfx card plus a flagship ryzen7 or i7.

Im using the Antec vp-450.

-Thanks for the help you answered my last question about what cpu to buy too

ermopalpopcorn :

The VP isn't exactly the better Antec PSU, you may want to consider replacing it in the near future.

Glad I was able to help before.

The Antec VP is an okay-ish unit, so it's not really ideal for your setup. Plus, the RX 480 can turn out to be a very power hungry card, so you should seriously consider changing the power supply, but that PSU you have is not an immediate threat, so it is safe to save money for a while and then get a good PSU instead of buying a bare minimum PSU today.

The psu wattage you need is primarily gated by the graphics card/s you will use.
Here is a nice chart which includes typical other components:

Keep your psu.
If it needs to work overly hard, you will hear the cooling fan spin up.

When it comes time to buy a new psu, buy only quality.
There are good and bad units from most makers.
Safest, I think is to buy Seasonic.
The new focus line as a very good one.

I have no problem overprovisioning a PSU a bit. Say 20%.
It will allow for a stronger future graphics card upgrade.
It will run cooler, quieter, and more efficiently in the middle third of it's range.
A PSU will only use the wattage demanded of it, regardless of it's max capability.

The main reason for a high efficiency psu is to reduce cooling fan noise; efficiency has little bearing on quality.
Modular is nice, but you are going to use most of the leads in a well sized psu anyway.
