What is the PSU wattage should I get?

[ivanteng880]

Hi I’m picking out a psu for my new build, I know I want a psu from Be Quiet but I don’t know what wattage should I get.

 

spec:

Ryzen 1600x (overclock)

B350-F motherboard 

coolermaster master liquid 240 

G skill trident Z rgb 2666 2x8 Gb

Curial SSD 250 Gb

Seagate HDD 1Tb 7200rpm

Asus Gtx 1080 Ti strix Oc edition (no overclock)

Cooler master H500P mesh white (2 200mm RGB fan and a black 120mm fan)

Corsair strafe gaming keyboard

corsair M65 pro gaming mouse

one usb reviver for G933 headset

450-550W. That should be plenty.

Get a 600W

[The L2d]

A 500 Watt gold standard should do fine!

[chckovsky]

It's much better to be safe than sorry - I'd say go for at least 600w. But perhaps more importantly, go for a quality one.

With 450W he's already well above what a stock Ryzen 1080 Ti will use. At 600W he starts getting to where the PSUs just get noisier.

550-650W. This 550W SeaSonic is a great deal RN, I have the 650W and it's great!

600 - 650W, 80+ Gold certified. Why not have the extra headroom?

Why 600W for a 200-350W PC?

When the PC consumes half of that?
Why?
600W Doesn't give him any advantages, especially on be quiet, where they most certainly use a higher RPM fan than 450 or 550W.

1st: He said he wants a be quiet PSU, that means he most certainly is in Europe.

2nd: 650W is utter nonsense and only makes sense when we are talking about High End Desktop systems and high end GPUs and Sledgehammer Overclocking.

_AND_ if there is no change in Plattform between 650 and 750W.

 

With the Straight Power 11, the 650W makes little sense and should be avoided.

450 is good

550W is OKish

650W is garbage

750W is good again

 

Just look at the modular Panel!

Why 600-650W for a 300W (max) PC???

WHy not have the extra headroom? Because its a waste?
Waste of money that's better invested elsewhere.

Gets higher damage in fault situations because of higher OPP/OCP Trip points

And higher Wattage ones of the same Plattform are never quieter without at least different heatsinks.

In some cases the ~550W is quieter than ~650W.

 

I've seen a diagram where the ~550W has around 625rpm, 650W has ~850rpm, ~750W again at ~625W.

 

So pls stop wasting peoples money with recommending "overwattage PSU"!

Just want to point out something: I really don't recommend overclocking a 1600X on that board. I had that board. The VRMs are a toaster and have a super lackluster heatsink. Don't bother running it at anything above stock speeds unless you can put a ton of air over the VRM heatsink.

 

Second, a 550W unit has plenty of wattage and anything more is kinda overkill. The Be Quiet Pure Power 10 would be a good choice if you're looking for one of their units.

Do you having any recommended motherboard for me? I want to overclock my Ryzen 5 1600X to 4GHz

Just saying, there's a very low likelihood that your chip will be able to hit 4 GHz. About 10% of chips can. You also need super high voltage to hit it (at least 1.4V, but no higher than 1.425 as that can damage the silicon in your chip), which that B350 Strix can't handle.

 

An Asus X370 Prime Pro is the cheapest motherboard with a decent VRM on AM4. I have one now after upgrading from that same Strix board and the VRM allows me to use much lower voltage for higher clocks speeds. My chip's absolute max at 1.425V with the most extreme LLC setting is 3975 MHz. Just shy of 4.0 GHz.

Do you think X370-F strix gaming motherboard will be good? @STRMfrmXMN

Yes, but it's probably more money than you need to spend.

Its OK, but power consumption of that Board is shit.

Way worse than on the Biostar X370GT7 I had before -> ~20W more under low loads....

I've said before that I'm a fan of the ASRock Pro4 for novice OC'ers who don't want to mess with LLC etc...

 

RE: 1600X hitting 4GHz, it's a bit more common that 10% (as far as I have seen in the buildapc discord), the lowest I've seen someone get it was 1.3V on the stock cooler (1600 non-X)

Really? I hated that board when I used it. No LLC is a serious dealbreaker if you want to overclock and fine-tuning the SOC voltage on the board isn't possible. Hard pass from me. Plus the horrendous Vdroop. Definitely my last choice for any B350 board I'd want to overclock on that has heatsinks.

 

But at what voltages with what LLC? I can probably get my 1700X at LLC5 to 4.0 GHz at 1.45V, but I ain't gonna dare do that. A lot of people just set the clockspeed to x40 in their BIOS and leave the voltage at Auto. 1.3V is pretty cool and low and stuff, but most people are not gonna hit 4.0 GHz and it's useless to include what clockspeed you want to hit in the OP because realistically you don't know if you chip can do it at all, let alone how much voltage it will need, thus corresponding to power draw.

Higher powered power supplies usually have longer warranties, sometimes up to 10 years. And an overpowered PSU don't need to work as hard, possibly making it quieter and more efficient (PSU are generally most efficient at around 50% load).

PSUs with longer warranties have longer warranties. Not PSUs with a higher wattage. For example, Focus Plus Gold 550W Vs Smart Power 850W. 10 Vs 3 years. 

The relative load doesn't matter. A higher wattage PSU will tend to have a higher RPM fan, making it noisier, whether it's during idle, or whether it's under load. For example, the noisy G3 550W is not as noisy as the G3 1000W or T2 1600W. 

The efficiency "curve" of a PSU is pretty much a flat line. It goes up vertically until ~10% load, then it's just flat.

Well maybe I should said that certain higher powered power supplies have longer warranties than lower powered units in the same series, to be more specific. Maybe I'm looking at older data (or just worse PSUs), but most of the curves I've seen indicate a small decrease in efficiency as it nears full load.

There's a small decrease in efficiency, but the fan RPM is still higher for higher wattage PSUs. 

Here's some tests.

That's fake news!

The Wattage has nothing to do with it.

The Quality/Series has something to do with it.

And the Warranty doesn't have to correlate with the quality. 

 

Or are claiming that Consumer units are of higher quality than Server/Workstation PSU?!

Why doesn't this fairy tale die?!

A PSU isn't a car, we aren't talking about some velocity or shit like that.

We are talking about Electronics and Heatsinking.

 

So for a higher wattage unit to be quieter, it has to at least have bigger heatsinks or we are talking about two different units.

 

 

But if we talk about the same unit with the same layout, that's not possible because laws of thermodynamics apply...

Usually the warranty within a series is the same. 
Different series might have different warranty. But within a Series its usually not the case.....

Yes, small - so small that two different PSU of the same model might have a bigger difference than the difference between peak efficiency and full load efficiency.

 

And especially if we are talking about 230VAC input, tha difference is really really small...

G2/3, 550/650w are 7 year, 750w+ are 10 year. That's the only series that i can think of though.

[chckovsky]

I stand corrected.

something like  Corsair TX650M ,  at some point u might consider to OC your 1080ti
