AI summary of the Reddit excerpts below — not a quote

The Corsair RM750x is widely regarded by the Reddit community as a gold-standard power supply unit, frequently recommended for its reliability and high build quality. It is often cited as a top-tier choice alongside competitors like the Seasonic Focus GX, with users noting its long-term durability and the convenience of purchasing official replacement cables directly from the manufacturer.

Pros

  • High reliability and build quality, often categorized as a top-tier PSU
  • 80+ Gold efficiency rating provides good power savings and heat management
  • Long-term durability, with users reporting successful use of older models in modern builds
  • Availability of official extra cables through Corsair's website
  • Quiet operation for most users, featuring high-quality internal components

Cons

  • Higher price point compared to B-tier alternatives
  • Occasional reports of high-pitched noises or clicking sounds during operation
  • At 160mm in length, it may be a tighter fit in compact cases compared to smaller units

Caveats

  • While 750W is sufficient for many builds, some users suggest stepping up to 850W or 1000W for high-end components like the 7800X3D to handle power spikes
  • One user noted confusion regarding fan control settings on specific versions of the unit
  • Availability can fluctuate, sometimes leading to long lead times or price premiums

Best for

  • Mid-to-high-end gaming PC builds
  • Builders who want a reliable, 'set-it-and-forget-it' power supply
  • Users prioritizing long-term component safety over initial cost

Avoid if

  • Building an extreme high-end rig that requires a larger power overhead (850W+)
  • On a very strict budget where a B-tier power supply would suffice
  • Building in an ultra-compact case where a 160mm PSU might obstruct cable management

Seasonic Focus GX-750 or Corsair RM750x are both reliable at that wattage.

I've found a few RM750x for under $100USD and would upgrade to that before getting a new GPU & CPU from outside the set budget

Would Corsair rm750x be a better choice? It has 160mm length but cables should be better iirc

That rosewill is B-tier which is better, but if your willing to spend $80 instead you can get a rm750x.

I'm using a 9700X / 4070 ti Super with an RM750X. Similar power draw. Haven't had a single problem.
