My PSU Corsair TX550M 80 Plus Gold is good enough for a Ryzen 5 5600X with RTX 3070 and peripherals?

For my current rig is the double what I need, accordingly with power supply calculator.

Nvidia recommends at least a 650W powersupply for the RTX3070. So, I wouldn't go below that. 

[Hector45]

Nope 550 watt wont cut it. I'm sure it will work, but it will be over spec and cause premature failure to your PSU.

[SilentSierra]

I'll considering upgrade to a 650w 80 plus gold.

Best regards.

[some1]

Nah, nVidia is very conservative with their rating and on top of that, they have to account for Intel CPU's that can pull 100-150W more than yours. 

3070 takes around 250W, up to 300W with OC. Your CPU is 65W, up to 100W with OC. Plenty of room for the rest of the system and peripherals. I wouldn't change the PSU unless you really start experiencing issues on the new system. 

 

[Bossco82]

I have a Corsair TX850M and I needed that to run a AMD 5600x and a 6800xt. At very least I would get a 650w.

Think about it a 5600x in a x570 can pull over 200 watts under load with peripherals and PBO enabled, I know mine can. I am talking about it in a whole system measured with a watt meter. My whole system can touch 450-470watts under loads if I really push it. Take 10% off 550w for errors and efficiency, that leaves you with 495 watts, its running very close. Be safe and get 650w.

Needed, yeah, right. 

I ran 5900X with 3080 on a 650W power supply without any issues for most of this year. You really don't need gazillion Watts PSU for a mid-range system.

Um yep, you were running an accident waiting to happen. Power supplies degrade over time. The closer you run them to the edge of their limits the quicker it will happen. Your system mate your free to run the risks. 

I would never advise someone to skimp on an extra 100 watts of capacity which is going to cost what an extra $20. 

[some1]

You've missed the OP question, it's not a matter of 20$, but rather buying a new PSU vs not buying one.

Good power supplies are one of the most reliable and long-lasting parts of the computer. Why do you think the manufacturers notoriously offer 6-12 years of warranty on a PSU while most parts in your PC have only 1-2 years warranty? 

Close to the 'edge' in case of a good PSU is also way above its rated wattage, which is given for continuous operation with some safety margin. Either way, a 5600X plus 3700 is waay below even 550W mark.

I changed my 14 years old PSU Corsair VX550 (2007) for a new one TX550M (2021) because the original power supply was unstable (too old) and causing power surge and over current.

The TX550M is good enough for my current rig:

• Core i5 4670k
• 4x 4GB DDR3 1600MHz
• GTX 1070
• HOTAS Warthog
• Pedals
• TrackIR
• 3x MFDs Cougar
• Headset
• Keyboard
• Mouse
• etc.

I intend to purchase a new rig next year or 2023, so, if this power supply doesn't work with new GPUs, I'll need to upgrade the PSU too.

PS: Like everything in Brazil, it's too expensive one TX650M, TX750M or TX850M. I purchased the TX550M because runs my current rig. In the end, I'll need to invest more money in the PSU anyway.

TX550M will work on the limit.

If you somehow find yourself in the need to run some stress tests to find an error you will be happy if the 650w holds what it says. I can, if need to be, push this system with a 1080ti north of 600w under full load. You dont want to do this with a 650w Gold PSU if you paid big bucks for GPU and CPU/Mobo as if it fries, chances are it fries it all.

Sure, everyday computing is way below that and even gaming with full power on the GPU is +/- 375w with this 5900X/1080ti combo but 550w sounds borderline to me, knowing many lower end PSU with Bronze or Gold don't hold up to their rating when tested and just explode, go up in smoke and flames, etc.. many many articles and YT vids about that.

 

[Bossco82]

Ok I can admit that I am wrong about the fact I did not read the OP's first entry on this thread. I missed the fact that he already has a recent Corsair TX550m gold rated PSU.

However while the components in the Corsair TX750m and TX850m are of a higher quality. The lower rated versions are not quite as robust. I am not using a PSU calculator, I am sitting here with a watt meter plugged in between the wall and my PC. If I run Cinebench R23 with PBO enabled using motherboard limits on my 5600x it pulls 205 watts out of the wall. If I do the same stock without PBO about 180 watts. 

SilentSierra I appreciate that your TX550m is a recent purchase and under regular gaming conditions you "should" be ok. However I would not let something like DCS run without a framerate cap or without using V-sync at something like 60hz. For example if I run DCS with a 60fps cap it draws between 290-380 watts. If I dont and I run it as fast as my PC can go its knocking on the door of 500 watts. That is using a 6800xt though. Please bear in mind that a 3070 running at full load can draw 250 watts plus. If you run that hardware on a regular 100% load it could potentially lead to problems in the near future. 

Look mate its your system, just be aware that if those components start to draw close to full load you could be asking for problems so run your games with a framerate cap.

[edmuss]

Running my 3600 and 3070 on a 5 year old antec 550w without any issues. The CPU is undervolted and overclocked but never had any problems with it.

Peripheral wise I have 3 SATA drives (1xSSD, 1xSSHD, 1xHDD), pcie nvme SSD, 3x140mm fans and every USB port filled.

I say suck it and see, unless you start getting instability is leave it for now but look at it being the first port of call if things do start to go downhill.

edit: @Bossco82 I thought the 3070 was 220w max? Or is that just the FE?

I suspect unless you're heavily benchmarking then it's not going to rear it's head. Don't forget that DCS is never going to pull that load out of the CPU in it's current form.

Edited December 21, 2021 by edmuss

[Bossco82]

Edmuss, I dont know which 3070 it is mate, the aftermarket ones can draw over 250w at full load. I'm giving advise so I always go on the side of caution when its about another persons system. I appreciate that with undervolts and tuning it could be fine. I'm just not taking that for granted.

If it was me and considering the power supply is so recent. I would probably risk it too. However I would have a eye on a watt meter to check how often it was drawing close to 450 watts.

First of all, if you're measuring at the wall, then you have to multiply by PSU efficiency, which is at best 93% in your case. So that 500W on the meter is more like 460W of actual PSU load (output).

Second, a typical 6800XT pulls 60-80W more than 3070 under full load. https://www.techpowerup.com/review/amd-radeon-rx-6800-xt/31.html

So both your observations and the calculator posted by @SilentSierra align pretty well, estimating around 400W for a system with 5600X and 3070. Well within capabilities of his current PSU, with a good margin for error. 

 

[BitMaster]

Ehhhh, wrong way round pal !

 

The 500w it draws from the socket is what goes INTO your PSU. Take that x 0.93 and you get what is leaving the PSU towards the board, the other 7% end up as heat in your PSU.

So the 500w is the real deal, that's the load that the PSU has to deal with in order to get the said 93% left to the board.

 

Once you have repaired a dozen of those "it made a loud noise, smoke and shut off..." you tend to get cautious with PSUs, marketing specs and 1000w for 99€ offers.

Your GPU will almost always draw full tilt power while you game, if it doesnt then something is wrong elsewhere or you play at low LOD and 1080p with capped fps etc..

Lol, nope, you're mistaken. Here's the actual efficiency verification report, from Wikipedia of all things. As you can see the power supply rated at 2200W actually takes 2370W from the wall at 100% load, to output 2240W at 94.6% efficiency. 

Power supplies are rated in output power, meaning the current * voltage they can actually deliver to the hardware. The excess heat is not included in the rating. Just like it's not included in the power rating of your car's engine. 

And please don't clutter the topic with your stories about cheap 1kW for 99$ power supplies. Everyone here has a decent PSU that can maintain its rated power, including the OP. 

[Bossco82]

There is a pointless argument here over something that should come down to common sense. I agree with the advise from Hector, Bitmaster and Lurker. Some1, I genuinely agree with your calculations about the capacity of a power supply at full load and what it should be capable of. The facts you present are correct and accurate. The advise from the rest of us is that running something on full load while possible is not recommended. My own rule of thumb is to look at what the maximum power draw of a system and then buy a power supply that is a good 20% above that, simply for safety. If a power supply is running at over 80% it will get hotter, that can "potentially" lead to problems.

Now the OP is in a different position he already has what he as and it would be uneconomical to make a change for him now. All we have done is confirmed what he already suspected, it could be on the edge if those components ran at 100%. For absolute safety the power supply should have more capacity. However if he is aware of this and keeps an eye on it. He should be ok. I have done this myself in the past. Doesn't make it a good idea though.

Silent Sierra you will be ok if you know what your doing but it is on the edge mate. Your PSU calculators are slightly out. Check with the 5600x at 4.2-4.4ghz and a more realistic voltage of 1.2-1.25vcore, The 3070, some have boost clocks going over 1850mhz possibly account for an overvolt of 10% too. Those calculations come out at around 550w. Under regular condition and under gaming with a capped framerate you wont get close to that though. All I am saying is be aware of it.

If you look closely at your own evidence, yes it states full load is 2367w input and 2240w output. Then look what it states for "typical" usage. Frankly I dont care if anyone wants to run their computer using a gerbil on a wheel. It is simply not "good practise" to use something like a power supply under condition where it can regular pass 80% of its capacity. Again I am not arguing that it is possible, it obviously is. It is simply not recommended. That rule goes for anything that produces heat while it is producing power from computer power supplies to car engines and everything in between.

Threads like these become misleading, everybody's comments and replies are correct from their own perspective. However what would be good practise.

For a system that comes out at 400-450W, and that's with a decent overclocking, a 550W power supply is exactly that. A good 20% above required power under full load.

No, they don't.  That's around 450 according to the linked calculator, and I agree with that estimate based on my own experiences.

[SilentSierra]

I found this site. I don't know if it's a good source. They recommend a 500w PSU for Ryze 5 5600X + RTX 3070:

I'm sorry. It was not my intention to create a bad discussion.

If TX550M isn't good enough, I'll sell it and purchase another with 100w more.

Best regards.

[Bossco82]

Hi SilentSierra,

Straight off let me apologise for not reading your first post properly. I didnt think you already had a power supply, I thought you were shopping around for one to power your new parts.

I dont think you need to sell your power supply and buy a new one with 100w more capacity. I think you should be aware you could be on the limit. I own a 5600x and know what it does playing DCS at 1440p. I have also fitted three different 3070's for friends and friends of friends since they were released. The power draw of the 3070 depends on which model you have bought. The power supply calculators you posted were a bit off when calculating "Full Load" meaning both your CPU and GPU are running 100%, which is unlikely but still possible.

If you run your 5600x with PBO enabled using motherboard limits and you have something like the MSI 3070, this could be possible...I adjusted the one you posted...

https://outervision.com/b/bX0RXZ

So if you game without V-sync or any kind of frame limiter this is what could potentially happen. If you do run with V-sync or a framerate cap of 60fps for example. I know for a fact that you will be drawing about 280-350watts from the wall during gameplay in DCS. In this case your absolutely fine. If you dont and you also like running benchmarks for the best score possible your on the edge of what you power supply can handle.

Please check this review of your power supply...it sums up its a robust unit...

Corsair TX550M Gold Power Supply Review | KitGuru- Part 6

If you have any concerns and if you can but a watt meter and check your own usage. I play DCS with a 60fps cap using a 5600x and a 6800xt, my usage varies between 300-440 watts, only because I use a framerate cap though.

Best of luck and take it easy mate...

[SilentSierra]

Thank you for your advice.

I purchased the TX550M recently. It's still on shipping.

I don't know. I can cancel the order and pay a little more for the TX650M.

The TX750M and TX850M are sold out here.

I think it is safe for my future upgrade.

Depending on the US dollar, Brazilian currency value, politics, etc. in the near future, I'll never see a RTX 3070 soon.

Best regards.

some1, I am sorry to say but you are far from hardware reality here.

If you intend to run a System at 400-450w for a long time, often, then you would never ever buy a 550w "Gold" PSU. Whoever does this doesnt know what he is doing or the guys who sell that don't know what they are doing. The quality of the DC current delivered is FAR from ideal at 80% load on Gold rated PSU's. There is a lot more to it than just raw wattage.

You should read up some reviews from HardOCP about PSUs. It's eye opening how quick some fail, some catastrophically.

 

SIlentSierra,

you won't regret selling it for a better device. The trend is still going UPWARDS in wattage, both for CPU and GPU on desktop parts. Rather buy 100w more than less.

HI Silent Sierra,

That is not a problem mate. If I am giving a quick reply to advise I always go on the side of caution. That being said I appreciate that parts supply might be more limited for you in Brazil over me in the UK. I dont know what financial and political restriction are effecting all that. 

If you find yourself having to work around having a TX550m its not the end of the world, far from it. This is a general guide from my experience fitting these components over the last 18 months. Lockdown here in the UK was pretty strict and a few people turned to PC gaming that didnt have much experience, so I have built a few systems as favours since the start of 2020. 

For the 5600x whether your motherboard is X570 or B550. You can go in the bios and enter some manual adjustments to PBO that should work for almost all 5600x CPU's

Manual limits, PPT=95w TDC=75a EDC=105, these are slightly over stock so use aftermarket cooling, or check your temps. You can also set the temp limit manually to 85 degrees C, then the CPU will auto downclock to stay super safe. Run Scaler x1, run 50Mhz overide and an all core -15mv. This should give you around 4400Mhz on all cores at 1.25v and a stable single core boost of 4.7Ghz. Plenty for DCS in single player.

For whatever 3070 you get, use the curve in MSI Afterburner and aim for 1900-1950Mhz sing 0.975-1.0Mv. Should be plenty for 1080p and also work for 1440p

These settings are just a starting point but it should keep your power usage and temps down a bit without sacrificing any performance in gaming.

Ive fitted a 3070 from Asus, MSi and Gigabyte and I must have fitted about 6 or 7 5600x's. These settings worked in all systems

Its an educated guess but this should keep you around 450w even at full load.

I concur with both the last two posters.

In one hand you will need more power sooner than later, on the other, Bossco82 suggested a suitable solution if you're stock with one type by lack of availability.

 

If possible at all I'd suggest a Corsair 750W (or another make but making sure you get continuous 750W output guaranteed), this should leave you with enough headroom for future upgrades.
