Pc crashes and restarts when under heavy load
Pc crashes and restarts when under heavy load
PSU performance is often reflected in the warranty duration they receive.
In summary:
- Up to 2 years – very poor reliability
- 3 years – weak reliability (e.g., Corsair VS/CS)
- 5 years – average reliability (e.g., Be Quiet! Straight Power 11, Seasonic G12, Corsair CX/CXF)
- 7 years – decent reliability (e.g., Seasonic Core/Focus GM, Corsair TX/AX)
- 10 years – solid reliability (e.g., Seasonic Focus GX/PX, Corsair RMx/HX/HXi/AXi)
- 12 years – excellent reliability (e.g., Seasonic Vertex/PRIME)
Between the three PCs I own, I have two Seasonic PRIME PSUs and one Seasonic Focus PX to supply power. Both PRIME units (12-year warranty) are handling our main systems, while the Focus PX (10-year warranty) is running my older AMD build. Detailed specs and images are available in my profile.
Regarding power requirements, a 650W unit works well for RTX 4070 and its Super variant. If you intend to use an RTX 4070 Ti (or Ti Super), opt for a 750W model. For RTX 4080 (Super variant), you’ll need a 1000W (1kW) PSU, and for RTX 4090, a 1600W (1.6kW) unit is recommended.
I understand. I was considering something similar to a 4060-4070 and think 650w should be sufficient for me. I've already selected one of the GPUs from the A tier on that list and plan to purchase it soon to test if the problem persists, thank you very much for your assistance.
I purchased an MSI MGP-80 Gold with 80+ Gold. It was listed as the top option, which seems to have resolved my issue. The LEDs are no longer malfunctioning, and the PC didn't crash when I ran three games simultaneously (previously it would crash within 15-30 minutes). Thank you for your assistance!
