PSU wattage ?
I'm considering purchasing a new AIO for my CPU and believe the Lian Li Galahad II Trinity Performance would be ideal. However, I'm wondering if an EVGA 750w Platinum rated PSU provides sufficient capacity for my system. My setup includes: CPU - Ryzen 5 3600 4.5 - 1.275 v with LLC set to mode 2 (using 135W in full load across all cores), GPU - GTX 1080 Ti which typically stays under 250W, RAM - 16GB 3800Mhz @ 1.35v.
The model of the unit is also being asked. The age of the PSU is unclear, and it's not specified whether it was purchased new, used, or refurbished. Additionally, the impact of GPU transient power spikes is being questioned.
The exact PSU model is EVGA 750W SuperNOVA 750 P6 Fully Modular 80+ Platinum. It's almost two years old and I purchased it brand new. I didn't mention that I'm also using a Cooler Master MasterLiquid ML240L RGB V2 AIO. I wasn't aware of the transient GPU spikes and didn't factor them in. Could you tell me about the power consumption of an AIO for the average user? The pump, fans, and total wattage are examples I consider. Thank you.
The EVGA P6 model from Seasonic is a high-quality PSU, ensuring solid build standards. While some users might worry, the reality is manageable.
To clarify the details, you can check the specifications here:

Although it's hard to determine the pump's exact power consumption from the specs, certain brands clearly disclose this information. For example, Cooler Master provides specifics for their AIO models.
Pump output: 2.36W
Fan power: 12V at 0.15A = 1.8W
With two fans combined, it's about 3.6W. Adding the pump at 2.6W gives a total of roughly 6.2W.
As I mentioned earlier, this is not a cause for concern. A helpful guideline: volts multiplied by amps equals watts.
For another reference, the Lian-Li AIO listed is:

The specs don't specify the pump wattage or fan amperage directly. The only power source mentioned is a SATA power connector. USB 2.0 internal connection is also required for data transfer, which provides up to 2.5W.
A SATA power connector can deliver up to 54W, but the Lian-Li model won't reach that level.
To get a more accurate estimate, research the AIO further—check reviews or images of the fan labels. These often list amperage ratings. For fans, looking at photos of the rear side can help identify the rating. Typically, fans under 6W are common, with most running at 12V and less than 0.5A.
I couldn't find any power draw or amperage details for that Lian-Li AIO. However, considering a single fan's 6W capacity, three fans would total around 18W. Adding the LEDs (2W–4W) brings the total to approximately 44–46W.
Overestimating can be risky, but underestimating could lead to issues. It's safer to assume a maximum pump power of 24W. If we add three fans at 18W each, the total would reach 54W, which fits within the SATA connector's capacity. Including LEDs (44–46W) would push it to around 88–90W.
Being conservative is wise, but the numbers suggest it should stay well below the expected range.
What is the model of your device and how is the fans set up?
Why do you believe a better cooling solution is necessary?
Has your existing aio stopped working?
Are you pushing your CPU to its limits?
Usually, your CPU should stay adequately cooled with a good air cooler.
Switching to a Ryzen 5 5600 is more economical and offers better value compared to spending heavily on a high-end power supply! The PSU is adequate.
i'm using a deepcool v3 55 matrexx that supports up to six fans. the aio is positioned in front to draw air, and since i also have a sc2 hybrid liquid cooled 1080 ti with its radiator in front, it serves the same purpose. on top, there are two bequiet 140 fans, and at the back, a thermaltake 120 fan is installed. i'm planning to upgrade nearly everything—cpu, gpu, psu, mb, ram, and case—but my budget isn't that flexible. for now, the best choice is to start from the bottom and focus on improving the cooling system. regarding your question about the aio, it hasn't failed. my ryzen is quite stable with 4.5 ghz and 1.3 v in llc mode 1.
What is your budget for all the upgrades?
What is the expected timeline for completing this?
Current processors offer better efficiency and require less special cooling.
Wait to upgrade your cooler until you have a new CPU or case installed.
It seems your primary focus is gaming.
Check if you need additional computing power or graphics capability.
Play your games, but reduce resolution and visual effects.
This helps the graphics card perform slightly better.
An increase in FPS suggests your CPU can handle improved graphics settings.
Stable FPS means your CPU might be the bottleneck.
If CPU performance is limited, consider upgrading it.
Improved cooling and overclocking will bring minimal gains.
If graphics are the constraint, upgrade your GPU.
Modern GPUs such as the 4060ti should work well with a 750W PSU.
