Endorfy Supremo FM5 HPWR
While Endorfy still doesn’t have ATX 3.x PSUs, it is releasing a cable for powering high-performance GeForce graphics cards directly (without an adapter) even with an “older” ATX 2.xx PSU. The Supremo FM5 HPWR cable has a 12+4-pin, or a 16-pin connector on one side, and connects via two PCIe eight-pin connectors on the other side, on the PSU side. In addition to the high current carrying capacity, Endorfy also emphasized installation convenience.
Endorfy Supremo FM5 Gold PSUs get native support for the latest GeForce RTX 4000 graphics cards with 12VHPWR/12V-2×6 connectors. That is, after buying the new Supremo FM5 HPWR cable. However, even with it, the Supremo FM5 Gold PSUs come out cheaper than models that already have the 16-pin PCIe cable included.
The Supremo FM5 Gold PSUs are also cheaper in their category (80 Plus Gold with modular cabling) because, of course, they don’t support the ATX 3.x standard. As you know, PSUs don’t acquire this only by meeting the 12VHPWR or 12V-2×6 power cable requirement, but there are also other requirements (for electrical characteristics) placed on them. Anyway, the main thing that causes users to tend to shy away from older ATX power supply standards, is elegantly solved by Endorfy with the Supremo FM5 HPWR cable. It has a direct 16-pin PCIe connector on one side and on the other side are two 8-pin PCIe connectors, which have long been used for external graphics card power supply.
Officially, it is a “600-watt” cable, which means it is rated for at least 50 amps. This is determined by the gauge of the wires, which is above standard for the power part – 1.31 mm2 (AWG 16), and also by the hollows inside the connector with a large contact area to minimize the transition resistance as much as possible. You don’t have to worry about the fact that the cable connects to the PSU with “only” two 8-pin connectors (instead of the four that are on the adapters for the GeForce RTX 4090). Endorfy made sure the 8-pin connectors are prepared to handle high current loads without getting into critical temperatures. This, of course, might not always be the case, and there is some dependence on the design characteristics of the 8-pin connectors themselves.
If mutual support is claimed and this cable is bound to a single model series of PSUs – Supremo FM5 Gold – everything should be suitably optimized for stable and safe operation. So, Supremo FM5 Gold PSUs are supported in performance variants of 1000 W (EY7A010), 850 W (EY7A008), 750 W (EY7A009) and 650 W (EY7A007). However, for the model with the lowest labelled sustained power (650 W) in combination with a very powerful processor, you can’t count on the maximum “capacity” of the cable, because it no longer works out on the 12-volt rail (CPU + GPU). Theoretically, a combined load of a RTX 4090 with a powerful Core i9 or Ryzen 9-class processor (probably mainly gaming load, which is lower in terms of the CPU…) could be withstood by that 650 W PSU, but that’s already out of the optimum efficiency range, which will also be the case for the 750 W variant. For GeForce graphics cards with relatively lower power consumption, such as the RTX 4070 Ti Super, however, the Supremo FM5 Gold PSU variants with lower sustained power (650 and 750 W) are already suitable.
To make management as easy as possible, the cable is up to 600 mm long (and reaches where it needs to go even in larger cases), and to prevent the cable bundles from coming apart in different ways, there are plastic clips on the insulation. The “type” of the cable is flat, so with the wires stacked in a single row next to each other.
The Supremo FM5 HPWR cable should be available in stores for about 14 EUR (this is its suggested price by the manufacturer). You can also find it under product number EY0P001.
