Hello 

I’m building (or upgrading) a system that will require serious power — specifically, a 2500W to 2800W power supply. This is for a multi-GPU workstation / mining rig / server environment, where stability, continuous operation, and efficiency are non-negotiable.

What I’m looking for:

• Enterprise / server-grade quality (redundant designs are plus)

• High efficiency (80+ Platinum or Titanium preferred)

• Exceptional stability and lifespan under heavy sustained loads

• Excellent cooling / low noise under full load

• Robust build, solid capacitors, good protection (over-current, over-voltage, etc.)

Top candidates I’ve found so far:

1. Super Flower Leadex Titanium 2800W – modular, premium build, top efficiency

2. FSP Cannon Pro 2500W – ATX3.0 design, popular among multi-GPU builders

3. Cisco UCSB-PSU-2500ACDV (2500W) – server rack unit, enterprise usage

4. Dell R7625 2800W PSU – reliable, though typically used in server chassis

5. Dell 15G/16G 2800W Titanium – high-end titanium unit, built for heavy workloads

If you’ve tried any of these in real world builds — especially under heavy GPU loads — I’d be grateful for your insights (thermals, longevity, ripple, actual delivered load, etc.). Also, if there are even better options I’ve overlooked, please share.

Bonus points if you can suggest retailers or suppliers in the EU / Greece that stock these units, or help me source them.

Thank you in advance — every recommendation helps a lot. Let me know if you need more specs or context from my end.
