PC Power Supplies & Cables: Pick a Full PSU or a Tesla Cable

Compare three ATX 3.0 power supplies with a separate PCIe-to-CPU cable by first deciding whether you need a complete unit, then narrowing the PSU choices by stated power rating, appearance, modular cabling, and connector details.

Last updated Aug 24, 2026

Selecting pc power supplies & cables gets confusing when a component cable appears beside complete ATX power supplies. The first decision is simple but important: are you replacing the PSU itself, or adding the named PCIe-to-CPU cable? Make that split before looking at price. For complete PSUs, the useful differences here are the stated power rating, colour and lighting, modular cabling, and connector terms.

Quick take

GAMEMAX, Segotep, and MSI MPG A1000G are complete power supplies; the Dual PCIe 8Pin to CPU 8Pin entry is a cable. That distinction matters more than comparing all four as like-for-like hardware. The three PSU titles all use ATX 3.0, PCIe 5.0, and 80 Plus Gold wording, so those shared labels do not separate them. Focus instead on each unit's specific presentation and cable details.

Decision matrix

  • Complete power supply rather than a component cable: Start with GAMEMAX, Segotep, or MSI MPG A1000G.
  • White ARGB build direction: GAMEMAX is the match.
  • Flat black, fully modular cabling: Segotep is the focused choice.
  • Fully modular PSU with detailed connection terms: MSI MPG A1000G is the relevant option.
  • Cable-only purchase: Choose the Dual PCIe 8Pin to CPU 8Pin cable rather than any of the three PSUs.

Product notes

GAMEMAX 1050W PSU

GAMEMAX 1050W ATX 3.0 PCIE 5.0 ARGB Smart 80+ Gold Power Supply UNIT (PSU) WHITE

Pick the GAMEMAX when a 1050W designation and white ARGB presentation fit the look and power-rating target of your build. It is one of the three complete PSU entries in this comparison. The limitation is visual: the title explicitly calls it white and ARGB, making it a narrower aesthetic match for a black-focused build. Its USD 119.99 listed price sits between the Segotep and MSI units. Choose it when the stated 1050W wording matters more than having flat black cables in view.

Segotep 850W PSU

Segotep 850W ATX 3.0 Gaming Power Supply PCIe 5.0 Full Modular 80 Plus Gold PSU

Segotep is the route for a build where flat black cables and a native 12VHPWR cable are stated priorities. Its fully modular description makes the cable-management angle particularly explicit, while the title identifies an 850W PSU. The limitation is its explicitly black colour direction, which may not fit every build plan. Its USD 99.99 listed price is lower than the other complete PSU entries. Select it when flat cable routing and the native 12VHPWR cable are more important than lighting-focused presentation.

MSI MPG A1000G Power Supply

MPG A1000G PCIE 5.0 & ATX 3.0 Gaming Power Supply - Full Modular - 80 Plus Gold

MSI MPG A1000G is for shoppers seeking a fully modular PSU with a particularly specific connector list: 4+4 CPU, 4 Pin Peripheral, 6+2 Pin PCI Express, 24 Pin, and SATA I are all named. Its ATX form factor is also stated. The limitation is straightforward: USD 130.00 is the highest listed price in this group. Select MSI when those connector terms are central to the build plan, rather than treating the model name alone as the deciding factor.

Dual PCIe 8Pin to CPU 8Pin Power Cable

Dual PCIe 8Pin to CPU 8Pin Power Cable for NVIDIA TESLA K80 P40 P100 (12.5CM

The Dual PCIe 8Pin to CPU 8Pin Power Cable serves a much narrower purchase: a cable titled for NVIDIA TESLA K80, P40, and P100, with a stated 12.5CM length. That clear model wording is the reason to choose it when those names are central to your cable search. Its key limitation is categorical, not a performance judgment: it is a cable rather than a complete power supply. The USD 9.90 price belongs to that cable-only role, so it should not be weighed as an alternative PSU.

Final recommendation by use case

If you want a complete PSU whose stated 1050W designation is the deciding factor, choose GAMEMAX. For a PSU choice driven by a native 12VHPWR cable, Segotep is the direct match. Select MSI MPG A1000G when its named connector assortment is the deciding detail. Choose the Dual PCIe 8Pin to CPU 8Pin cable only for a cable-focused purchase, with the TESLA K80, P40, and P100 wording in mind.
