Hi fellow forum people!

daft question, but do I need to uprate my PSU?

Current rig:
AMD Ryzen 5800x
Arctic Freezer III RGB
Gigabyte 3070 Aorus Master
32GB G.Skill Trident Neo 3600Mhz RAM
1 TB M.2 SSD (Main C drive, for OS, frequently used stuff, and my main games)
1 TB HDD (for random games and general stuff that doesn't need to load fast)
4 TB HDD (Long term photography storage)
Lian Li 207 case (recent upgrade)
custom sensor panel running with Aida 64 and RTSS

I do have a small undervolt on my GPU, but CPU is stock. Cinebench scores in the 1400s depending on what I shut down or keep running.

I've currently got a Corsair RM750i PSU I got a few years ago, it's doing fine and generally I don't notice any particular issues, but I'm getting huge packet loss in CS2. Mostly it's low, but I get prolonged spikes of 30-70% (lasting for 15-20mins or more), and I'm rubber banding in some matches.

One of my friends suggested I should be running a 1000w+ PSU, but I'm struggling to see how that could affect packet loss in a particular game, that's more of a network issue in my mind. Should I put a PSU upgrade on the priority list?
 
Thanks @Tetras, I was pretty sure it was fine, PC Part Picker suggests around 550w for my PC, but wasn't sure if there was something I was missing. I don't see any other issues, so the PSU seems to be doing just fine.

PSU issues due to power spikes that exceed the capacity usually just cause shut downs or resets.

Packet loss is most likely due to your network (or possibly a driver problem), as you said. Are there other people using your network when you're experiencing the packet loss?

With online games, it can also be a routing problem, if the server is located somewhere your ISP doesn't like connecting to, or the connection is not a good one.

The event viewer might have more details on any network problems.
 
Thanks, I'll have a look at the event viewer and see if there's anything there.

There's usually a few connections in the house, phones, TV etc, though last night it happened when I was on my own, so it should have just been my PC that was active. My internet speed is good, 350Mb/sec (Virgin Media), and we usually get most of that even at busy times. Ping is low, 23ms normally to the servers. I had the internet connection come into the house right by my PC, so it's an ethernet connection to the router that sits on my desk. I update the graphics drivers regularly through Geforce experience too.

I think it's to do with the game implementation just being a bit buggy, so I'll see if I can do a traceroute first, but I might try reinstalling windows, have been putting it off as it's a bit of a faff.
 
i'd manually find the most UpToDate driver for the nic, dont trust windows to just do it. also what BIOS are you on?

Do a few speed tests and line checkers, just because you getting 350MB/s doesn't mean you don't have a fault in some way on your line.
also how old is your router i find that at about the 2 year mark most off brand router's iv had in the passed would start to show faults where the internet would almost come in waves.

almost garunteed to be a problem with a network server that's routing your packets and outside of you or your ISPS control.


you could try changing your DNS so it uses a different public one instead like google https://developers.google.com/speed/public-dns/docs/using
cloud flare have one too https://www.cloudflare.com/en-gb/learning/dns/what-is-1.1.1.1/


you could also try typing "ipconfig /flushdns" in command prompt.

Flushing the DNS cache removes all information stored in the cache, allowing your device to remove outdated entries and get new ones. This can be useful for troubleshooting website access problems, as websites frequently change their IP addresses
 
Thanks chaps,

Tried a WinMTR trace and my connection looks fine, 100% of packets sent and recieved (a couple of steps looked like they were not reporting) so both ends look fine.

Looking through a few settings it looks like my ethernet conection is randomly dropping to 10mb. Tried it over the weekend, and the issue seemed solved after disabling windows ability to the adapter turn off and on automatically, plus updating the drivers. But tonight I was getting a bit of loss again, and sure enough it's dropped again.

Got a new cable to try, and I'll dig into the ehernet adaper settings a bit more.

I assume you don't have Intel i255-v LAN in your motherboard?

Thanks, That's what is says in device manager. It was on auto negotiation in Speed and Duplex, so I've switched it to force 1Gb/s.

For some reason the power settings had reverted to allowing windows to turn the adapter it off/on again, so removed windows control again and it's back showing 1000Mbs in the router now. Hopefully that sorts it!
 
Thanks chaps, had a good test tonight and that's seemed to sort most of the rubber banding, and although I'm still getting a little bit of loss in game (that could also be out of order packets due to a change in how loss is measured), it's nowhere near what it was before. Reduced from 50-60% to mostly none at all, with occasional 4-5% spikes, and my headshot percentage went up significantly.

That's returned it to playable levels at least! I'll have a fiddle about with my rates and see if reducing the packet size that way has any further impact, but it does feel like my connection is a whole lot better.

ahh I've just checked and mine was on auto.

no Idea what it defaults too, I'm guessing most people would never need more than 1gb mode anyway?

I'm not sure, but I don't think they're all affected and there are three revisions of the chip.
