Is the Corsair 550 Gold sufficient to power an RX 6800?
Is the Corsair 550 Gold sufficient to power an RX 6800?
Hey, I just purchased a nearly new system (if I could trust a very reliable store in my country) with an RX 6800, after which I’ve been using the 1660 Super. I’ve heard that the Corsair cm550 PSU should suffice, but after installing the card and SSD first, I encountered an issue with the RDR2 driver—specifically, it reported a missing latest driver even though I had one. I thought it was a common problem, so I decided to launch the game without the FSR option in settings. After about 15-20 minutes, the game crashed to desktop.
Next, I tried it on Detroit: Become Human; it lasted roughly 10 minutes longer before crashing again. Then I reduced the graphics to Full HD mid and it didn’t crash for two hours. Based on this, can I reasonably assume the problem is with the PSU and should I replace it?
I’m running low on funds after the purchase, so I’d like something decent but without needing room for future upgrades. My setup includes:
- B450 motherboard
- Ryzen 5600G
- RX 6800
- 2x8GB DDR4 RAM
- 1 x HDD
- 2 x SSDs
- 2 fans (in case)
- Stock CPU cooler
- 1 CD-ROM drive installed.
I’d appreciate any advice or suggestions, and thank you in advance. Good day to you all.
Corsair recommends a 650 for that CPU and GPU setup.
You can test it yourself via the provided link.
The two SSDs and HDD increase power consumption, so a 750 offers more flexibility.
Don’t go low on the PSU quality—consider purchasing another Corsair model.
Which Corsair PSU do you currently own?
Corsair 550 Gold isn't a Gold rated PSU. When it comes to your PSU, consider how recent it is—ideally a 750W unit with solid reliability. Aftermarket AIB and overclocked setups demand more power, so recommendations from AMD should be adjusted accordingly. Just a thought: you're investing well in components, so protecting that value makes sense by using a robust PSU with extra capacity for better performance and longevity.
Thank you for your message. I’m writing about a small phone used at work and suspect there might have been some errors. After checking, I believe the Corsair was CS after confirming it had a gold certification. I’m not at home, but it’s definitely a Corsair 550. I want to protect its components, but first I need some general confirmation that it really looks like a PSU issue. I’m on a tight budget, so I’m hesitant to take it to an official service store. However, I think it would be safer to purchase a good gold + 650/750 depending on the current safety needs for those parts and possible voltage spikes. I assume you’d prefer recommending 750 over 650 since the latter might be too risky. I’ve had my PSU for about 3-4 years, and currently, in my country, around $100 is the maximum I can afford. Before buying, I’d like to know if it’s a good idea, as the PSU is just based on my calculations. It crashes at 4K in games but runs fine in Full HD. Thank you for your thoughts!
I think it's likely a CS550 model with Corsair and gold certifications. I'm planning a clean install, removing the HDD and CDROM after purchasing the PSU, but first I want to double-check if my assumption about a PSU fault is correct based on the symptoms. Should I still recommend a 750 PSU over a 650 for handling potential spikes? If 650 seems possible, I'd prefer something better, but 750 would require more investigation. Most importantly, I need to confirm the reliability of my belief that it's probably a faulty PSU, not just a damaged GPU or CPU. The new paste installation might be the issue, or the HDD could be old and causing problems since the system won't start without it. What do you think?
Actually, the 6800 model is produced by a third-party board manufacturer, MSI Gaming Z Trio. It suggests an 850W minimum power supply, whereas other MSI 6800 models are smaller in size.
Remember the golden rule of PC building that the power supply is the lifeblood of your computer if you don’t allow for power spikes ETC ETC.
You might be surprised if you damage components or encounter problems using older under-wattage PSUs.
Looking back at the PSU is arguably the most foolish and significant error in PC building!
If you can afford a good PSU, then why build the PC?
It's a valid concern about the gigabyte RX 6800 gaming OC, but I've noticed those official requirements can often be too detailed. After some research, most opinions suggest it should work fine. Still, there seem to be issues, and I'm trying to figure out if it's my mistake or if the PSU is handling everything well.
Yeah, what U said is true, however keep in mind i did not plan to upgrade psu at all, and im not building anything just wanted to buy new gpu after confirming however i could for my limited knowledge that it should work and i need to know before buying new psu if that is probably the mistake i made There. So i would really appreciate any thoughts , but especially something saying "yea the psu with this behaviour seems to be too weak if it crashes games under higher needed performance " . I have no problem in admitting my mistake and i assume 750 would be needed and 650 might not cut it after the input i received here, however i still dont know if i should buy better psu or this may be influenced by something else. I know it can be any part, but all of them worked perfectly before, and my limited knowledge tells me its psu, but i would rather have someone else with broader knowledge tell me to gry nad buy new psu, or idk do sonething else, test it , anything really. Thank You for Ur thoughts on this tho.
You could visit the repair shop and share your thoughts, especially if you believe there might be an alternative solution.
I purchased a 7900xt last year without intending to upgrade my PSU. At the time, it wasn't certain whether my PSU would suffice for the device. However, I upgraded because it became uncertain at that moment. Now, considering the additional components I've added to the PC since then, it's very close to reaching the maximum capacity of my old PSU to run the current setup.
Having more than what you currently require allows for future expansion without needing a new PSU.
