The estimated TDP after overclocking for I3 8350k is 8350k.
Hello everyone! I'm just starting out with overclocking and would really appreciate some guidance. I plan to purchase an i3 8350k and will be overclocking it, while also running a gigabyte g1 970. I'm curious if the 450 Watt power supply I have now is sufficient to run both an overclocked i3 8350k and an overclocked 970.
Finstar suggests it's unlikely, even with a high-quality power supply. On regular speeds it works, but overclocking reduces efficiency. The system probably draws under 250w during games, so 450w seems excessive.
Experience suggests it's unlikely, even with a high-quality power supply. At stock speeds it works, but overclocking would reduce usage below 250w during gaming. A 450w unit wouldn't suffice considering the system's overall power draw and the PSU's aging.
Uncertain where you got your details from, but a well-optimized 970 consumes only about 190w during gaming.
An overclocked 8350k draws around 70w while gaming.
The rest of the system would likely use roughly 40w.
Overall, it's about 300w during moderate to high overclocking.
A top-tier 450w model could handle it.

Experience shared some thoughts on the power usage details. A well-overclocked GTX 970 consumes around 190w at full gaming load. The 8350k runs about 70w under similar conditions. The rest of the system would likely use roughly 40w, bringing total gaming consumption near 300w with moderate to high overclocking. A top-tier 450w unit could handle it.

I'm curious about what you were using when you thought about those figures. The 190w rating for the GTX 970 applies only at stock speeds; the average at your usual speeds matches the one in the linked review, which is 168w plus a 22w boost—bringing it to 190w. In another post, the i3 8350k at 4.8GHz while playing Total Warhammer uses 71.34w, not just "my 70w." The power readings from the wall can be misleading because they don't reflect the total system load or PSU efficiency. Also, those tests were done under full CPU usage, which is why I used "gaming load" terminology. I'm not sure how reliable the overclocking data from BitTech really is, since other reviews suggest the CPU power increase isn't that significant. For instance: Lastly, TDP doesn't measure actual power consumption.
