What is the best PSU for an RTX 4090 build?

Question

What is the most reliable PSU for a 4090 that wont randomly shut down on me? My current unit keeps tripping during heavy rendering work in Blender and Im honestly fed up. I need something stable ASAP because my project deadlines are coming up and I cant afford another crash. Budget is around 250 bucks maybe?

Just catching up on this thread. Honestly, do not mess around with cheap units if you are running a 4090 for work. I had issues with another brand cutting out during renders, so I switched to the Seasonic Vertex GX-1000 1000W 80+ Gold and it has been rock solid. It is built like a tank and handles those power spikes perfectly. Trust me, it is worth paying a bit more to avoid the headache.

Honestly, grab the Corsair RM1000x 1000W Gold. Its rock solid. I render all day and never had a single crash. Seriously, its a lifesaver for my 4090 builds.
