Choosing between pc power supplies & cables can come down to a deceptively simple question: do you want the lower listed price and a cable-focused setup, or more detailed connector and component callouts? The Segotep 850W and MSI MPG A1000G both target ATX 3.0 and PCIe 5.0 gaming builds, but their emphasis is different enough to make the choice clearer.
Quick verdict
Pick the Segotep 850W ATX 3.0 Gaming Power Supply when the listed flat black cables, cable-management focus, and native 12VHPWR cable are central to your build plan. Pick the MSI MPG A1000G when its more detailed connector list and Japanese capacitor specification matter more to you. The listed price gap is $30.01, so this is a decision about the features you want called out rather than two completely different types of power supply.
At-a-glance comparison
| Detail | Segotep 850W ATX 3.0 | MSI MPG A1000G |
|---|---|---|
| Listed price | $99.99 | $130.00 |
| Shared platform details | ATX 3.0, PCIe 5.0, full modular, 80 Plus Gold | ATX 3.0, PCIe 5.0, full modular, 80 Plus Gold |
| Listed connector entries | 24 Pin | 4+4 CPU, 4 Pin Peripheral, 6+2 Pin PCI Express, 24 Pin, SATA I |
| Cooling entry | 1 fan | 1 fan |
| Listed color | Black | Gold |
Where each one wins
Segotep makes the stronger case for cable presentation. Its flat black cables are specifically positioned to support cable management, which is a practical draw for a build where the internal appearance matters. It is also the lower listed-price choice at $99.99.
MSI stands out for specification detail. The MPG A1000G names several connector types rather than only a 24 Pin entry, and it calls out 100% Japanese 105°C capacitors. That is a concrete component detail for shoppers who prefer a more extensively specified configuration. The Gold color is also the listed finish for anyone matching that look.
Product notes
Segotep 850W ATX 3.0 Gaming Power Supply

Segotep is a natural fit for a build that calls for the named native 12VHPWR cable to PCIe 5.0 graphics cards. That cable is specified up to 600W, which is a raw listed cable figure rather than a broad performance claim. The full modular configuration also includes flat black cables, with cable management explicitly part of the design focus. Its limitation is aesthetic rather than functional: the listed color is Black. Shoppers who specifically want a Gold-colored power supply will find MSI better aligned with that preference. For a black-focused build where the cable callout is the priority, Segotep is the more fitting choice.
MSI MPG A1000G PCIE 5.0 & ATX 3.0 Gaming Power Supply

The MSI MPG A1000G is the better match for shoppers who want several connector types expressly named, including 4+4 CPU, 6+2 Pin PCI Express, SATA I, and peripheral connections. It also identifies 100% Japanese 105°C capacitors, giving component-focused buyers a specific construction detail to weigh. The limitation is straightforward: its listed price is $130.00. That higher entry point is worthwhile only if those named connector entries, the capacitor callout, or the Gold finish fit your intended build. If none of those details influence your choice, the Segotep's lower price may be the more direct route.
Final choice by use case
Choose the Segotep 850W for a black build where the native 12VHPWR cable is the deciding feature. Choose the MSI MPG A1000G if you want an ATX 3.0, PCIe 5.0, full modular, 80 Plus Gold unit with a more detailed connector specification and a Gold-colored finish. Both cover the same core platform standards; the deciding factor is whether cable emphasis or MSI's more detailed component and connector callouts better suits your build.
