Check if a 1000w power supply is enough for the RTX 3090 and i7-14700K with an AIO.
Check if a 1000w power supply is enough for the RTX 3090 and i7-14700K with an AIO.
Hello, I recently purchased an i7-14700K to replace my i7 7700K due to a good offer.
I have an EVGA Super Nova P6 1000w power supply, and I’ve heard the RTX 3090 can experience significant power spikes when under load.
Will the 1000w PSU be sufficient for both the new CPU and my GPU?
I don’t have the funds to upgrade to a 1200w unit at this time.
I haven’t installed anything yet, but I’m hoping it will perform adequately without reaching its power limit.
I also have an AIO Corsair H100x water cooler for the CPU if that would be helpful.
Thank you in advance.
Because you already have a 1000W power supply, why not give it a try and find out what happens?
With a 14th generation processor, ensure your BIOS is up to date and avoid messing with voltage settings or overclocking.
Current processors offer limited room for overclocking, making it not worth the effort.
You're experiencing a significant boost in computing performance.
Because of sudden load increases, consider a power supply with at least 1.2KW capacity and solid construction. Gamers Nexus shared a video on this topic.
I own an EVGA Super Nova P6 1000w PSU, but I'm unsure how old it is. Even if it's brand new, I wouldn't recommend using it.

Yes, they are. Each PSU's management of those spikes varies significantly. The 3xxx RTX cards experience substantial power surges. The 3090 can reach 550w without issue. Some Seasonic PSUs struggle with this, while others perform well. The same applies to Corsair. The P6 is a solid PSU. It's not the top choice, but it's quite good. It has certain limitations: If I were you, I wouldn't upgrade just yet. It might work fine for your setup, or it might not. If it doesn't meet expectations, opt for a better PSU.
Before I checked, the PSU was rated at 1000W, which exceeds 550W. Going over 550W would create more problems for the motherboard than the PSU itself, especially since the 3x8 connectors can only supply 450W and the PCIe slot adds up to 525W. A small 25W increase is manageable for a PSU but not for the PCIe slot.
