Do i need a power supply with higher wattage

[Mr. Nipsi]

Hello, 

 

So me and a friend are building a new pc. We got everything bought now except a power supply. But we are not sure how big of a wattage we need. I think a 650 watts is good enoug, but It will just be quite sad if shows to not be enough.

 

the specs of the pc is

amd ryzen 5 2600x - we will be overclocking it

rog strix b450-f 

Ballistix sport LT ddr4 2x8gb 2666 MHz 

samsung 970 evo 500gb

Seagate barracuda 7200 rpm 2tb

asus rog rtc 2070 strix oc 8

nzxt kraken x62

 

in the nzxt h500 

 

Hope anyone can help us choose the best psu for our build

[Slottr]

Yes it is.

 

Look at tier S/A out of this list:

 

[Mr Technician]

650w will be plenty. EVGA gold is quite good.

[Spotty]

Looking at about 200W on the GPU and 100W on the CPU, maybe more if you're overclocking. 650W more than enough. Personally I'd go a good quality 550W. What's your budget and country?

[Princess Luna]

even 500w would be enough, grab something of quality checking the tier list as reference;

I threw in your specs, made a few guesses, and yes, 650W is actually slightly overkill for your system.

 

I'd recommend a 600W (or higher) PSU. The approximate system draw is in the ~510-530W range, and you want to leave some headroom (550W is probably fine, but cutting it a bit close).

 

If you want to stick with the 650W, that's absolutely fine.

So we got a maximum of 800 dkk to use on psu. Which is around 120 usd. 

We are from Denmark.

Not familiar with Denmark PC stores. Any stores in Denmark with websites that you buy from that I could look at to get an idea of what's available and pricing?

Proshop.dk and komplett.dk are the ones I have mainly been using.

Be Quiet Straight Power 11 and Corsair RMx are good picks within your budget.

Thanks a lot I’ll be talking to my friend about what he thinks about the psu’s you have proposed

gosh how many lists are there? can't they just merge all of them into a single one?

Not really. The mods can merge the various threads together, but they'll just appear in chronological order.

 

Someone would have to manually go through all lists and combine the information.

be quiet Straight Power 11, 550W should be available over there.

Other list was retired I believe, this is the prime one from what I know of

What? 

My build draws  ~350W on regular load, he would be 100% fine with good quality 550W PSU.

@Mr. Nipsi If you do not plan on SLI/Crossfire in the future, RM550x will probably be the best choice, considering that Straight Power 11 is out of the budget:

From the wall? So about 310W on 110V AC?

Rough estimation on the actual pull, haven't gotten watt meter yet to measure pull from the wall

What's your build?

 

Besides, you need a PSU capable of max load, not regular load. Gaming doesn't even typically stress a GPU to 100% power consumption (at least, not beyond the occasional spike, if that).

450 would be more than enough....

Did you calculate that out or are you just guessing?

 

Not meant as an attack against your suggestion, but I put in the parts the OP has into a PSU power draw calculator, and at max power draw, he'd be using more than 450W.

No harm no foul my friend. Others are suggesting even smaller PSU's.

 

While a 500W or 550W would probably be fine (since during gaming, your CPU and GPU will not generally reach max power draw), my calculations (which I will admit, erred on the side of caution) list max power draw at around 510-530W. Add in some headroom and 550W is pushing it. 600W is the safe bet.

 

Granted, this is factoring in increased voltages on the CPU for OCing. If the OP OC's without any voltage increase, his headroom increases.

Cx 550m is a good choice

Here's from Anandtech's review. 340W at the wall, so about 310W DC. That's with a 7820X.
