650W PSU
Reddit take
AI summary of the Reddit excerpts below — not a quote
A 650W power supply is widely considered the standard 'sweet spot' for mid-range gaming builds, providing ample power for modern CPUs and mid-tier GPUs. While generally sufficient for most users, the consensus emphasizes that unit quality and brand reputation are critical, as lower-tier 650W units may not handle transient power spikes as effectively as high-quality models.
Pros
- Sufficient for mid-range configurations including Ryzen 7 CPUs and RTX 3070/4070 or RX 7600 class GPUs.
- Cost-effective entry point for reliable power without the premium price of 850W+ units.
- Commonly cited as 'more than enough' for builds with a total load around 400W-500W.
Cons
- Limited 'wiggle room' for future upgrades to high-end, power-hungry components.
- Quality can be inconsistent among budget brands at this wattage level.
Caveats
- Users strongly advise against 'cheaping out' and recommend sticking to known, high-quality brands to ensure stability.
- While some users successfully run high-end cards like the 5070 Ti on 650W, others suggest 750W+ for peace of mind with similar hardware.
Best for
- Mid-range gaming PCs.
- Budget-conscious builders using components with a combined draw under 500W.
- Systems where efficiency and cost are prioritized over extreme future-proofing.
Avoid if
- You plan to upgrade to top-tier GPUs (e.g., XX80 or XX90 series) that recommend 750W-850W minimums.
- You are building a high-end workstation with multiple power-intensive peripherals.
This summary uses balanced time weighting with about a 6-month half-life. The evidence is based on Reddit discussions from early 2026, primarily within PC building communities, reflecting hardware standards of that period.

650w psu (I know I need 750w)
If you build it yourself, this is roughly what you should target: - PSU: 650W from a known brand (don’t cheap out here)
Pretty sure they don’t make those, so 650W it is. Could you get away with less, sure, probably but a 650W PSU isn’t absurdly expensive either.
I vote that if you’re not seeing any instability to stick with the 650W you have.
Finally the PSU is fine. I have a 650 with a 5800xt that pulls like 120w plus a 6700xt and don’t have any issues.
For psu, 650W is sufficient future proofing. Probably less than $100 as well.
My current build is a B650M plus wofi mobo, ryzen 7 8700G (to game while the gpu arrives), 16gb ddr5 6000mhz, 1Tb nvme 2.0 SSD, all that with a 650w psu
650w is 5k
UPDATE: I bought the Arc B580 and a 650W PSU. Will be installing them soon!
Just upgrade the psu, I wouldn't be super comfortable running over the rated spec of the psu unless your psu is good quality. And I don't think many 650w are.
