Looking for a new PSU that's quiet, high-quality, modular, and around 500W?
Looking for a new PSU that's quiet, high-quality, modular, and around 500W?
I'm currently running a Ryzen 7 with a TDP of 65W and an RTX 3050 6GB with a TDP of 70W. I don't really intend to upgrade much further. I prefer quieter, stable, and energy-efficient systems rather than full-size gaming setups.
In short, my Corsair HX520 is likely around 15 years old now. It still works perfectly. BUT: The PC has spent a lot of time in a smoky room, and the fan has become noticeable over the years. Since I don't think it will remain silent or efficient after 15 years of smoke, I should probably start thinking about a replacement.
What should I look for? I checked the forum here and the pinned threads, especially those discussing Corsair quality. However, I noticed most high-quality options seem to exceed 500W, which is clearly too much for my setup. I think even 500W might be excessive. I'd really like another Corsair since this one has been reliable, but it seems top-tier models aren't available in this power range.
Any suggestions?
It's quite accurate. You might have to accept a 650 rating.
In the past three months, I came across several suggestions for better low wattage power supplies, but I didn't record them. Surprisingly.
Typically... I'd consider Seasonic and Super Flower options. Could other users have more detailed advice?
Perhaps the Seasonic Focus GM 550 is worth looking into—it seems semi-modular, though you might prefer a fully modular design for some reason?

Above Corsair is likely around 750 watts, but it has a good reputation and is frequently discounted.
I'll keep following this discussion for my own needs, as I might require a replacement PSU soon.
You made a wise choice by purchasing a PSU with a solid warranty.
A robust warranty serves as an indicator of product quality.
Consider Corsair RM and Seasonic focus/vertex as good examples.
Strong performance is essential, especially since future graphics cards often require upgrades, which are typically the most demanding parts.
The PSU should operate efficiently in the middle portion of its power range, allowing it to run without excessive noise.
Modern graphics cards can experience high demand spikes, far exceeding their standard power consumption.
A difference of around 10 watts usually represents a minor price increase.
For initial recommendations:
Seasonic Vertex GX-750 with a 10/12 year warranty: [link]
Corsair RMx 750x with a 10 year warranty: [link]
The decline in quality 400-500w PSUs stems from production costs matching those of 650w units, while consumers anticipate a $10 discount per 100w reduction. Manufacturers struggle to profit from lighter models.

Just because a PSU claims 650W doesn’t guarantee it will draw more power from the mains.
If efficiency remains similar at a certain output, it will still draw the same current.
Review the datasheets for the PSUs you’re evaluating. If prices match, pick the one that fits your needs.
I’d prefer a reliable 650W over a 500W mainly for extra margin. The advantage is the extra capacity means the PSU isn’t under strain as much. Under similar conditions, it should last longer and produce less internal heat, reducing wear and tear.
I’m revisiting this issue again. I tried delaying the purchase of a new PSU as long as possible, but the HX520 fan was still quite noticeable. Eventually, I upgraded to a Corsair RMx 750W model from 2024.
The situation has changed: my PC is near the bed and runs almost nonstop. The RMx model starts showing coil whine after several hours of inactivity. I often wake up hearing it. Disabling C-State didn’t resolve the problem.
Google also mentions that the RMx series tends to have this issue, so I won’t be replacing it with another identical unit.
There hasn’t been any change in system performance—likely drawing about 200W max. At this point, I’m uncertain if a 750W unit is truly excessive and could be making the system less efficient overall.
