850W PSU Planning for RTX 5090 Builds in SA
850W for RTX 5090 needs a full-build check, not a simple yes. Review GPU guidance, CPU draw, transient load, connectors, PSU quality, and upgrade plans before deciding.
Read moreMarvel Rivals on the RTX 5090 at 1440p should be judged by refresh target, settings balance, CPU pairing, and thermal stability. For SA gamers, the best result comes from matching the GPU to a capable 1440p display.
Short answer: Marvel Rivals is comfortable on the RTX 5090, landing near 240 fps at 1440p on maxed or near-maxed settings.
At 1440p the RTX 5090 pushes 240 fps in Marvel Rivals on high settings, with 1% lows staying smooth enough that you never feel a hitch in normal play. Turning on upscaling such as DLSS or FSR Quality lifts the average further and leaves headroom for ray tracing where the game offers it. If you target a high-refresh panel, the card has the grunt to keep frames above your monitor's comfort zone, so the limiter becomes your display, not the GPU.
To keep Marvel Rivals rock-steady on the RTX 5090, set the in-game preset to High rather than chasing every Ultra slider, then enable Quality-mode upscaling. Cap your frame rate just below your monitor's refresh, for example 138 fps on a 144Hz panel, to remove tearing and reduce input lag. Keep your GPU driver current and drop shadows one notch; those two changes alone often add 10 to 15 fps without a visible quality loss.
Drop to 4K and expect roughly 120 fps, while at 1080p the card climbs toward 360 fps, so there is plenty of overhead for a faster display. For Marvel Rivals specifically, a CPU bottleneck only appears at lower resolutions, so a current Ryzen 7 or Core i7 keeps the GPU fed. That balance makes the RTX 5090 a sensible match for a high-refresh monitor rather than overkill that sits idle.
Yes, DLSS or FSR Quality typically lifts the average by 20 to 40% with minimal image loss. On the RTX 5090 that pushes Marvel Rivals comfortably past your panel's refresh in most scenes.
Because the RTX 5090 holds around 240 fps, a high-refresh panel makes the most of it. A 1440p 165Hz or 4K 144Hz display turns those extra frames into a visibly smoother experience.
A current Ryzen 7 or Core i7 with 16GB or more RAM keeps the RTX 5090 fed at 1440p without bottlenecking. Pairing it with an older quad-core would cap your frames in CPU-heavy scenes.
Run Marvel Rivals on High with Quality upscaling and cap frames just under your refresh; the RTX 5090 then holds 240 fps at 1440p with no tearing.
