Chieftec VEGA M 850W ATX v3.1 PSU Review

Box & Bundle

The box features a photo of the product on its front, accompanied by several small badges that depict various features. Internally, the protection is good, with packing foam surrounding the PSU.

The exterior design is interesting, thanks to the punched fan grill, which allows for good airflow due to its large perforations. The power specifications label is on the bottom side, covering most of the space there.

The modular panel has nine sockets, including a native 12V-2×6 header.

Modular Cables
Description Cable Count Connector Count (Total) Gauge Cable Type
ATX connector 24 pin (600mm) 1 1 18AWG Tinned Copper
8 pin EPS12V (650mm) / 4+4 pin EPS12V (+150mm) 1 1 / 1 18AWG Tinned Copper
6+2 pin PCIe (650mm+150mm) 2 4 18AWG Tinned Copper
12+4 pin PCIe (610mm) (600W) 1 1 16-24AWG Tinned Copper
SATA (400mm+155mm+155mm) 2 6 18AWG Tinned Copper
4-pin Molex (400mm+155mm+155mm) 1 3 18AWG Tinned Copper
AC Power Cord (1370mm) – C13 coupler 1 1 16AWG

The cables are long enough, but unfortunately, it is not good to see dual EPS connectors on a single cable, especially with 16AWG gauges up to the first connector. These connectors can draw a lot of power, so having a pair of them on the same cable is a hazardous idea.

The number of peripheral connectors is sufficient, and the distance between them is sufficiently high.

It is great to see all cables using the proper conductor (tinned copper) and not the cheap Copper-Clad Aluminum (CCA) solution.

  1. Hello which PSU would you recommend if you had to pick from : Chieftec VEGA M PPG-750-C, Corsair RMe Series RM750e , Cooler Master MWE Gold V2 ATX 3.1 750W. They are priced the same and I am looking for a PSU to pair with my 5070 TI…

    1. I would get the one with the better support in the region, because performance differences are not that dramatic among these. Check for their noise output also (average noise) output.

  2. I’m curious how worried should I be for the inrush current this model has. It is quite competitively priced where I live, and I’m inclined to get it if it is not a big deal in terms of long-term reliability or safety on the secondary side.

      1. Thank you, Aris!
        As I see, the inrush is similar on Cybenetics as well. There is also an option to have the Cougar GEX Pro (650W which is not rated at Cyben) for similar price as well. Although Chieftec’s Vega M seems more reviewed than the Cougar. Which one would you recommend?
        PS – It is amazing to get guidance from professionals like you!

        1. Just retested the Chieftec PSU for inrush current, as expected values are way lower. I cannot say about the GEX Pro 650 since I haven’t tested it or at least I don’t remember doing so, my team 🙂

          1. Thank you for your guidance and updated information! I do not have any second thoughts about the Chieftec then! 🙂
