Does Dell 500W PSU 5K7J8/Y7R0X compatible with Dell G5 5090?

Discussion

Hi everyone,

I’m currently looking to upgrade my Dell G5 5090 i5-9400, GTX 1660,32GB Ram for renderering with Blender. I’m planning to install an ZOTAC RTX 5060 Ti 16GB.

I found a Dell 500W PSU on Dell Canada for $139.99 CAD, but the site only lists compatibility for XPS 8940 and OptiPlex 7080. ChatGPT said these share the same proprietary 6-pin/4-pin pinout but I need to be 100% sure.

The Plan:

  • System: Dell G5 5090 (currently 360W PSU).
  • Upgrade PSU: Dell 500W PSU (Part # 5K7J8 or Y7R0X).
  • Upgrade GPU: RTX 5060 Ti 16GB (180W TDP).
  • ZOTAC RTX 5060 TI length ~220.5 mm length,
  • Primary Use: Long Blender render
  • Note: This is not a gaming build.

My Questions:

  1. Can anyone confirm this specific PSU fits the G5 5090 chassis and motherboard?
  2. Is 500W sufficient for a 180W card, with a i5-9400 CPU or am I pushing the limits of this Dell unit too far?
  3. Are there any known issues with the 5K7J8 (Delta) vs the Y7R0X (Chicony) versions ?
