With one easy change to its 12VHPWR connector, MSI has made it very apparent when the connector is not plugged in all the best way right into a graphics card or PSU. The bit that is meant to be on the within of the connector is completely yellow.

In the event you see yellow, you must hold pushing.

The compact micro-fit connector is historically all-black, as most are, however MSI has proven off new PSUs over at Computex 2023—together with the MEG energy provide pictured—that change the interior connection plastic to a shiny yellow. Thus, in idea, decreasing the chance of a dodgy connection unbeknownst to you that might kill your card.

It is a surprisingly easy means to assist mitigate what has been prompt to be one cause for melting energy connectors on graphics playing cards. The 12VHPWR connector can ship as much as 600W by way of a single cable, nevertheless it received off to a tough begin with the RTX 40-series graphics playing cards as person experiences rolled in exhibiting clear indicators of harm to the connector throughout use.

A dodgy connection is just a part of the parcel for the 12VHPWR connector, nonetheless. Early investigations prompt that one particular kind of 12VHPWR connector, the so-called 3 Dimple, was extra susceptible to creating an improper connection, leading to temperatures rising and in some instances the connector failing. The choice, 4 Spring, is supposedly extra sturdy. 

That is since been backed up since by Intel, who’s the writer of the ATX 3.0 PSU specification, who beneficial that producers solely use the 4 Spring design henceforth.

However a loose-fitting connection is one positive strategy to make issues worse. One thing as painfully easy as a two-tone connector may nicely do some good for fiddly builds where you may’t entry the cables simply to verify they’re securely mounted. And there is the added bonus that for anybody who hasn’t been stored abreast of the latest melting graphics card incidents could be extra more likely to safe the 12VHPWR connector all the best way with such a visible cue in proof.
