Quick take
The first decision in pc power supplies & cables is easy to miss: are you choosing the power supply itself, or solving a graphics-card cable-routing problem? The Segotep 650W, Segotep 850W, and MSI MPG A1000G are ATX power supplies, while the HUHOU cable is a PCIe extension with a GPU-specific connection layout. That makes the cable the wrong category of purchase when an entire PSU is needed, and makes a full PSU excessive when the immediate issue is routing an 8-pin GPU connection.
Among the three PSU choices, the key distinctions are the open-box versus new condition, non-modular versus full-modular layouts, and the different 650W, 850W, and 1000W configurations named in their titles. Start with the kind of component your build calls for, then narrow by those concrete differences.
Listed price comparison
The listed endpoints are separated by $116.01, with the GPU extension at one end and the MSI 1000W PSU at the other.
| Item | Listed price | Position within range |
|---|---|---|
| Open-box Segotep 650W PSU | USD 52.99 | |
| Segotep 850W ATX 3.0 PSU | USD 99.99 | |
| MSI MPG A1000G 1000W PSU | USD 130.00 | |
| HUHOU GPU PCIe extension cable | USD 13.99 |
Decision matrix
- Need a complete ATX power supply: Focus on the two Segotep units or the MSI MPG A1000G; the HUHOU item is an extension cable rather than a PSU.
- Prefer a new-condition component: The Segotep 850W, MSI MPG A1000G, and HUHOU cable are listed as new. The 650W Segotep is open box.
- Want a full-modular PSU layout: The Segotep 850W and MSI MPG A1000G fit that description.
- Need a GPU cable with one female end and two male ends: The HUHOU cable is the item with an 8 Pin PCI Express female connector and dual 6+2 Pin PCI Express male connectors.
Product notes
Open-Box Segotep 650W Non-Modular ATX PSU
For an ATX build that calls for the named 650W configuration, this Segotep GN-650 gives a straightforward route. Its 80 Plus Gold designation, 120mm fan, and 20+4 Pin connector make the intended setup clear without adding a cable accessory to the purchase. The important trade-off is explicit: it is open box and non-modular. That combination makes sense for a shopper comfortable with that condition and fixed cable layout. It is less suitable for someone whose build plan specifically calls for a new-condition unit or a full-modular arrangement. Choose it when the listed 650W ATX specification is the target.
Segotep 850W ATX 3.0 PCIe 5.0 Full Modular PSU
The Segotep 850W is aimed at a build choosing an ATX 3.0 and PCIe 5.0 power supply with a full-modular cable layout. A native 12VHPWR cable and flat black cables are both named, giving it a concrete appeal when those cable details matter to the build plan. It is also listed as new and 80 Plus Gold certified. Its limitation is price placement: USD 99.99 sits above the open-box 650W Segotep. Select this configuration when its named standards, native cable, and modular design are more relevant than the lower listed price of the 650W alternative.
MSI MPG A1000G PCIE 5.0 & ATX 3.0 Gaming Power Supply
The MSI MPG A1000G is a direct match for a shopper seeking the named 1000W ATX configuration with a full-modular layout. Its connector list includes 4+4 CPU, 4 Pin Peripheral, 6+2 Pin PCI Express, 24 Pin, and SATA I, while the description also names Japanese 105°C capacitors. Those specifics give a clear reason to choose it for a build planned around that connection set and its PCIE 5.0 and ATX 3.0 designation. The limitation is equally clear: USD 130 is the highest listed price of the four. Choose it for the stated configuration, not merely because its wattage figure is numerically larger.
HUHOU GPU 8-Pin to Dual 6+2 Extension Cable
Pick the HUHOU extension cable when the job is specifically to route one 8 Pin PCI Express female connection to dual 6+2 Pin PCI Express male ends. Its GPU-to-GPU splitter description and black-and-yellow finish distinguish it from the three ATX power supplies, and the USD 13.99 listed price keeps it in a very different purchase category. Its concrete limitation matters just as much: it is described as a GPU 8-pin-to-double-PCI-E splitter extension, not a CPU 8-pin cable or a complete PSU. It addresses a graphics-card cable-routing requirement, while the other choices address selecting the main system power supply.
Final recommendation by use case
Choose the open-box Segotep 650W for an ATX build planned around its fixed-cable, 650W configuration. Choose the Segotep 850W when a new, full-modular ATX 3.0 and PCIe 5.0 setup is the priority. The MSI MPG A1000G is the fit for the named 1000W configuration and its listed connector selection. Choose the HUHOU cable only when the requirement is a GPU PCIe extension with its specified female-to-dual-male layout.
