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

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.

For the second or third time, please stop cluttering this thread with horror stories about exploding poor quality PSU's and vague comments with no substance.  The poster already has a brand new, solid quality model with 7 year warranty, that is recommended at HardOCP and gets good reviews like

It won't blow up from simply running at 70-80% of its rated power. The measured AC noise/ripple at this load level is also perfectly fine, the efficiency stays around 91%, which is well above "Gold" or even "Platinum" standard requirements. In fact, both reviewers pushed it high above 600 watts in their testing.

Sure, I wouldn't want to use this PSU with RTX3080, 5950X, or any high-end Intel CPU, but that is not the topic of this thread. For a setup like 5600X with 3070, it's perfectly adequate.

Always easy to spend somebody's else money on things he doesn't need.

Horror stories about exploding PSUs ?  Just google it up, it's no secret.

Aiming at a constant 80% load..... please do your homework before you give false and dangerous advice.

80% is peak load in some gaming scenarios, and even that's assuming solid OC on both CPU and GPU. Not constant load 24/7.

Anyway, that's another post with no merit on your end, just ad personam. The tread starts to spin in circles so I'm done, my first answer in this thread still stands. 

Merry Christmas everyone and happy New DCS patch

To Silent Sierra,

I dont want you to be mislead by anything in this thread so I will make very clear why I gave the advise I have. Under no circumstances do I think you are at risk of having a power supply go bang, smoke or catching fire, no explosions mate I promise.

This is what your at risk of and its a very slight one. So all this is said with a very big "IF"!

Say you get a really nice 5600x a cherry pick, and you put it in something like a higher end X570 motherboard and your cooling it with a better quality 240 AIO. Then you go and enable PBO with motherboard limits, 200mhz overclock over-ride and leave all the voltages on auto. Then when your in a game or a benchmark it loads up and gives the CPU +30mv without any limits on the TDC or EDC and a temperature limit of 95 degrees C. That is going to just pull current and wattage until it potentially reaches its temp limit. What could happen is you would get crashes and problems that are because its a 550 watt PSU and not a 650 watt. Not because you have a bad CPU.

Then for the 3070, if you have a founders edition, then no worries really. If you buy a MSI 3070 Gaming X Trio for example. I fitted one in September. That thing literally tried to reach for the moon in clock speed. The one I tested pulled about 280 watts and was hitting 2070Mhz with 1900Mhz on the memory. It was peaking over 1.1vcore and never reached its temp limits it just pulled and pulled wattage. Now like Bitmaster and Thinder advised a higher wattage power supply would simply manage the load. The system I worked with did have a 650-750w and everything worked just fine. Even when it was pushed to its limits.

Put these two rare scenarios together with a 550w power supply and it could/might be the perfect storm for crashes and restarts. Simply because if both reach for their highest clock speeds together during gameplay or a benchmark and there is not the juice there for both of them in that scenario. This could then lead you to believe you have a CPU, GPU, Dram or Mobo problem when its actually your power supply.

Please refer to this PSU Calculator simulating that happening, https://outervision.com/b/XZIGKs I think this is why Nvidia advises a 650w to cover a worst case scenario like I have described.

Now like Some1 said and is correct in saying so. This is unlikely. I agree that if you take precautions and your aware of what the worst case could be, you will be fine. I offered advise in this thread regarding voltages etc, as a way to avoid this potential perfect storm. However that does not mean that the opposing advise given is incorrect, to cover yourself for any potential scenario you need a minimum 600w capacity. Just be fully informed its to cover you in case the above was to happen. 550 watts is on the edge of what these components could potentially require.

All this is said with a very heavy dose of the word "IF" 

Always try to pick your power supply for the very worst case scenario for the exact components you have and with any potential upgrades in mind. I have not personally come across a PSU going bang, not in 20+ years. I have come across a few systems where an upgrade, usually a GPU has caused a system to begin crashing and restarting because spikes in power draw have overwhelmed a PSU not quite up to the job. I hope I have shared enough information from both sides of the fence so you can make an informed decision. 

Merry Christmas to everyone and I hope you get your system set up very soon. Take it easy.

I canceled the Corsair TX550M order and I paid a little more for a XPG Core Reactor 850W 80 Plus Gold.

I expect this one to be a good PSU for high end GPUs.

Thanks @Bossco82 and @some1 for the fight.

Merry Christmas and Happy New Year for everyone.

Best regards.

Done.

Now I have a overpowered PC.

Now, I just need the other devices like Mobo, CPU, Memories, SSD M.2 and RTX 3080 ti.

Looking good man, well if you changed to a 3080ti, trust me you will need that one. Hope you get your setup how you want it soon mate. Best of luck.
