Concerned about whether my PSU can support a GPU upgrade given the numerous drives and devices in my setup
I have a setup that’s a jumble of mismatched components from various sources, and I always intended to refresh some of the older elements when possible, especially the graphics card. When I started browsing eBay for used GPUs, I was taken aback by how affordable the RTX 3080 Tis is—priced between 500 and 600, particularly if you’re lucky at an auction.
I researched the appropriate power supply for a machine like this and noticed several mentions of 750 watts. I assumed an 850-watt PSU would suffice. But since my build includes many other parts as well, I consulted several PSU calculators, which gave conflicting advice—some suggested around 650 watts, while others went up to 1200 watts. Most fell in the 800-watt range, which makes me a bit concerned.
Here’s a link to a PcPartPicker page, though it seems my system is quite chaotic:

Key components I have:
CPU: 11700K (stock)
RAM: 2x32GB DDR4 (potential upgrade to 4x32GB if prices drop)
GPU: EVGA GTX 1070 (planning a possible replacement with a 3080 Ti later)
Fans: 1x 230mm, 3x 200mm, 1x 140mm
Storage: 1x NVME drive, minimum two more, 1x Blu-Ray Burner
5x SATA HDDs connected to a RAID card
Sound card and several USB devices
PSU: Seasonic Prime PX-850 850 Watt
I’m concerned about the power requirements. Even with an 850-watt PSU, the sheer number of components could strain it, especially with the RTX 3080 Ti. I’m unsure when I’ll actually get a replacement or if I’ll end up swapping to something else entirely (the next generation of RTX cards will likely be out soon).
Your PSU is ideal, 750w is the suggested level for regular users. The additional components you have increase power draw but not excessively, making the extra 100w manageable. I don’t think there’s a problem running the system; in fact, I usually suggest a 1000w PSU now. This way, you’re prepared since power-hungry cards can spike, and it adds more stability for future upgrades.
This PSU is adequate for the 3080Ti and its internal design seems solid. I wouldn’t recommend switching to another PSU in the next three years—it’s more than sufficient to remain reliable. You can also continue using a 4080 with this PSU, as it can consistently deliver full rated power and handle short periods of higher load, such as 1000 watts. So there’s no need to worry about the PSU; it’s fine.
Peripherals such as hard drives consume minimal power, around 10w, mainly during startup. You might consider enabling staggered HDD startup if your motherboard supports it. The Seasonic Prime PX850 offers excellent quality power supply. It should work well with a 3080ti. Cards from the 3000 series can experience significant power surges. If your PSU cannot manage one, you may encounter an abend without any damage.
