Will my 550w power supply suffice for a Ryzen 7 3700X along with the RTX 4060?
Will my 550w power supply suffice for a Ryzen 7 3700X along with the RTX 4060?
A big one (sorry I didn't verify it before 😅) I'm not sure about my feelings
I just discovered after taking apart my PC that it's a Cooler Master MWE 550w 80+ White PSU. It's not a Gigabyte 500w 80+ Bronze model, which confused me because of my old system. It should be paired with my current setup.
R7 3700x and 1060 3GB GPU. My PSU should handle the RTX 4060, right?
Since the 1060 is a 120W card and the 4060 is 115W.
Other parts include:
- 2 SSDs (1 M.2 + 1 SATA),
- RGB mouse, keyboard, and mousepad,
- 3 x 120mm fans (2.6W each),
- a drawing pad
PS: don't blame me for the 4060
The power ratings are sufficient, but I'm curious about how long you've been using it and the various loads it's handled. Since it's a bronze model, a higher-quality gold option might be preferable.
If your PSU is the P550B reviewed on Tom's, it represents an older, lower-quality "group regulated" model. This implies that when you heavily load the +12V rail with the CPU and GPU, the +5V and +3.3V rails will deviate from their specifications. The Gigabyte P550B is available at a reduced price, which is its primary benefit. Besides minimal EMI emissions, its compact size and correctly configured OPP are its main strengths. However, there aren't many significant positives to highlight for this product. It appears Gigabyte simply adopted an outdated platform from MEIC and applied its label without sufficient testing or optimization. Still, it's unclear whether the numerous issues with this model can be resolved given its aging design. Apart from poor overall performance and low efficiency—particularly under light loads—the fan speed curve is very aggressive due to the need to cool subpar capacitors. The bridge rectifier lacks a proper heat sink, and the FETs sourced by MEIC raise concerns about quality. We were taken aback that this unit passed our tests, but pushing it further would likely cause failure, especially without over-temperature protection. Performance claims shouldn't be relied upon solely based on advertised output. Just because the P550B can deliver a 3700X and support the RTX 4060 doesn't make it an ideal choice. The +12V ripple is significant, regulation is weak, efficiency is low, and so on. Even a Corsair CX550 Bronze PSU outperforms the P550B, while the CX550 itself is hardly recommended. A better alternative would be a Corsair RM650 Gold PSU. Nevertheless, you might still extract several more years from the P550B before it fails, even though the 5-year warranty is no longer valid. The decision rests with you.
it's not the P550B, sadly, 😅 i believe upgrading to something better would be a good idea. it's almost been four years now, and the ATX power cable on the motherboard is really tricky to remove and reinsert.
Do you enjoy playing games? The 3-year warranty marks the PSU as intended for an office computer.
Poor low-quality unit, especially if it's the 230v model—it's even worse. I recommend replacing it with a much better one.
i would highly advise against attempting that psu if it has been running for a while—it’s likely to fail eventually, and i strongly suggest removing it from use. there are many reliable power supplies available that will last longer, such as the sonic focus, corsair rm series, depending on your budget. buying poor quality equipment could result in a spectacular firework display while damaging your pc. for better options, consider the links below:
