Is 450w enough?

[MooseMan45]

So I recently ordered some new parts for my gaming pc, here are my specs:

 

AMD Ryzen 5 1600

MSI B350M Bazooka

EVGA GTX 970

2x4 DDR4 2400mhz

1TB 7200RPM HDD

 

My exact psu is a: CORSAIR CX-M Series CX450 450W 80 PLUS BRONZE Haswell Ready ATX12V & EPS12V Semi-modular Power Supply

 

According to Outervision PSU Calculator my recommended wattage is 420w, but I don't know how accurate that is...\

 

Any help is appreciated

I feel like I've answered this exact question recently?

 

But yes, it's fine.

It should do just fine as long as you don't plan to plug 30 USB devices in

I had a different account, but I used ccleaner to clean pc and lost my login password lol

Also is there anyway to monitor how much wattage certain components are using in game sort of like hwinfo on temps but with wattage?

Even then, USB 3.0 can only do 5W per USB port so that's 150W on top of a 250W system. Would still be fine

Yeah, that PSU is fine for that. I've put a CX450M in my 1700X and GTX 970 system, both overclocked, worked fine.

External hardware, like a Kill-O-Watt, and then, if using those, you have to factor in PSU efficiency to calculate how much power is being drawn from the PSU versus the wall.

 

My 1700X and GTX 970, both under overclocked stress, draw 369W, if that means anything to you.

Dang so that means I even have a little wiggle room for overclocking my cpu?

My 1700X at 1.38V and heavily OC'd GTX 970 definitely use more power than your system and I'd still have wiggle room on a 450W unit. 

 

That said, make sure the VRM on your board has a fan running over it. The MSI B350 VRMs are a little weak but the heatsinks are very good, so just get some airflow over them if you plan to overclock.

Will do, still relatively new to Overclocking so I'll be cautious

Remeber you want to stay in the 80+ curve for efficiency on power supply.

???

short answer : yes it would.

I don't think you understand how that works sir...

I don't understand what you are talking about.

 

As for load, good PSU are rated for 100% load at higher ambient Temperature like 40 or 50°C...

He's talking about the efficiency curve on the PSU. The efficiency changes with the load the PSU is under. Most PSUs have peak efficiency around 50-60% load. It's something to factor in when you want to save on electricity.

 

This is the curve for the CX450M when using 230V (source is Dutch).

Nope, somewhere between 30-70%, depending on the PSU. Many have their peak as low as 40% load, some even 30% (Cooler Master V550).
And between 40 and 80%, there isn't much difference in Efficiency...

And 0,5% isn't really worth arguing about anyway because that's the Manufacturing tolerances...

pls Link to the site/test and don't just steal their stuff, whoever that did...

 

Anyway, that diagramm is a bit weird, but the difference between the best point isn't that big. 

Is it really worth arguing about that?!
 

Its not like we are talking about 5% Difference but somewhere around 2%...

In this case, not even that and only around 1,5%...

So you have proven his statement to be kinda wrong...

Hold on there tiger. Why are you always so super hostile when someone responds to you  

 

Source is this one: https://tweakers.net/productreview/136105/corsair-cx450m.html - It's a user review from a Dutch tech community and his findings are considered credible throughout the community, which I am also a part of.

 

And the difference also differs per PSU. It's quite slim for this PSU, yes. I just wanted to clarify what Josh was talking about.

Just your imaginiation.

Wasn't hostile this time, just posting it the way I think.

Beeing polite is overrated and people ignore you if you are polite in Forums, so there is no point in trying to be polite.

 

If it is about the picture: Check Copyright Law and quote rights and such. 

In short: You have to link to them, if you use any material.

Yes, I know the Mask, did some discussions with him over at @jonnyguru's Forum.

Yes, with this it was small.

But I did some research for other discussions and found out that in worst case scenarios we are talking about 2,5% Difference between peak Efficiency (wherever it is)...

In most cases its much less and around 2%...

 

And there is this:

 

And that's how most manufacturers see it, most of them just don't say it clearly.

Just gonna jump in here and say I have the CX450M with a 1600 and GTX 970.  All good!

With all the efficiency improvements in recent years, a 450W PSU will cover all but the highest end stuff.

Also, higher wattage power supplies are generally less efficient at idle loads. So the real world difference in the power bill would be even less noticeable.
