Cooler Master Elite Gold 850 — fully modular ATX 3.1 80 PLUS Gold PSU

850W ATX 3.180 PLUS GoldFully modularPCIe 5.1 12+4-pin

The Cooler Master Elite Gold 850 (MPX-8505-AFAG) is an 850W fully modular ATX 3.1 power supply with 80 PLUS Gold efficiency, designed for gaming PCs built around a PCIe 5.x graphics card that need clean cable management.

It supports PCIe Gen 5.1 with a native 12+4-pin GPU cable, uses flat black modular cables and a 120mm rifle-bearing fan, accepts 100–240V input with active PFC, and is protected by UVP, OVP, OPP, OTP and SCP. Cooler Master quotes at least 90% efficiency at typical load.

Before you order: Storage connectivity is modest: 4 SATA and 2 Molex. Most current builds use M.2 SSDs, but a PC with several 3.5" or 2.5" drives may need more SATA connectors.

What's in the Box

  • Elite Gold 850 power supply
  • Modular flat cable set
  • AC power cord and mounting screws (box contents not itemised by Cooler Master)

What It Means in Practice

  • Fully modular means you fit only the cables you use, so small and mid-tower cases stay tidy.
  • The native 12+4-pin cable connects RTX 40/50-series cards directly.
  • 850W leaves headroom for a high-end GPU plus a strong CPU in a single-GPU system.
  • Wide-range 100–240V input.

What Will Not Work

  • Only 4 SATA and 2 Molex — multi-drive builds may run short.
  • Do not mix modular cables from other PSUs.
  • It is ATX, not SFX — it will not fit small-form-factor cases.
  • Cooler Master does not publish the +12V amperage on the product page.

Frequently Asked Questions

Is 850W enough for an RTX 5080?
For a single card of that class with a mainstream or upper-mid CPU, yes. Send us your parts list to confirm.
Are the cables sleeved?
They are flat black cables, which are easier to fold and route than round sleeved cables.
Singular Expert Insight · Buyer's Guide
The Elite Gold 850 is the tidy-build choice: fully modular, ATX 3.1 and a compact 140mm length that fits most mid-tower cases. If you run many SATA drives, look at an 850W unit with more SATA plugs in our PC power supplies range.
✓ Buy it if you want a compact, fully modular 850W Gold unit for a modern gaming PC.
✕ Skip it if you need more than 4 SATA connectors or an SFX unit.
→ Also consider the Inter-Tech Argus HA-850BA4 if you need 8 SATA connectors.
Send us your CPU, GPU and case model and we will confirm fit and headroom before you order.
