New GPU and PSU

[richardav]

My specs are

Windows 10 AMD Ryzen 7 1800X Processor RAM: 16 GB / Storage: 2 TB HDD & 512 GB SSD Graphics: AMD Radeon RX 580 500w

My question is can i put a Nvidia 1080ti in there i seen somewhere you need 600w plus for 1080ti if that's the case how do i know what new PSU to get. Is there anything else i need to know. I never put new parts in a pc before.

How do i find out if a PSU will fit my motherboard? The PSU came with the pre-built pc.

What "500W" unit do you have? You'll need to look at the labelling on the side for a model name/number.

500W, even a good quality unit, will be cutting it pretty close. A 1080TI is a 250W TDP Card (and, under 100% load can pull a bit more).
+ 105W CPU and maybe 50-100W for the balance of the components, it could be doable.... but not really recommended.

Your motherboard should use standard ATX Power supplies - I'm not aware of any OEM shipping proprietary units with Ryzen.

Never run a powersupply over 70% of its max rating. 0.707 is normally the factor used.
This keeps everything safe.
Personally, 600w is what I would go with.

Honestly, that's a horrible blanket statement.

While yes, you should always aim for headroom over and above max potential load, there's other factors at play.
1. Day to day power draw. For example, if the OP typically gamed at 1080p, the rig isn't going to draw >400W, but may spike a little higher (ie >70%)

2. The quality of the PSU itself. Quality units are actually rated for their max output @ X'C (40-50'C for quality units) and are warranted as such. Yes, PSU degredation exists, but PSUs are rated for their max output for duration of their warranty period. For example, a PSU like an EVGA SuperNOVA G3, or a SeaSonic Focus+ Gold are warrantied for 10 years. Obviously, having some headroom there is nice,and will help with efficiency etc.... but it's not going to 'kill' a PSU any faster.

3. On the opposite end, a lot of junk/mislabeled PSUs would be unlikely to be capable of 70% of their [strike]outright lie[/strike] listed max. In that case, you'd be lucky to consider an X wattage PSU as something appropriate for 50% of that output.

First off, dont assume everyone buys crappy PSU's. Generally these PSU's are not what people buy when they are building a system.
The PSU you are talking about are more for computers that people dont mod. Although they want to later on, their inbuilt PSU is made to suit the task.
70% is generally the standard for everything, always. Amplifiers, revs in a car, whatever the device, 70% is a good reference. Even when doing load circuits in houses, its a general rule of thumb.
So I stand by what I say. a 600 Watt PSU will easily handle 400 watts, you will need and also the system will be running about optimal. Too low of a draw, you waste power, too much draw you waste power.

My methodology is quite reasonable, but you have to be picky.

Now according to you, the PSU must only give out its specs for the time its guaranteed. This may not be the case because now their are laws on Electronic systems in Europe where they must state how long they should expect electronics to work outside of their warranty.
Everything has a warranty, its the law in Europe and that warranty has to be honoured no matter what. Life expectancy is now playing a big part in the way electronics should last outside of warranty.

I am digressing, THE rule of thumb applies in this case.

Tom just did a recent update of their PSU's about 2 days ago, check that. You don't need to get bogged down with technicalities if you are not a computer/electronics person.

I checked the PSU and there is nothing on the side to indicate what make it is. Only a very long number with a barcode

Most likely a bad unit. With a system of that caliber, do not risk it. Also, it came with the pre built pc so most likely garbage.
