Choosing pc power supplies & cables is difficult when the decision is not simply about wattage. A compact SFX designation, a named PCIe cable, an ATX 3.0 label, or modular cable routing can each matter more to a particular build. The practical payoff is to sort by the requirement you already know you have, then use price to settle the close calls.
Quick take
Start with the form-factor wording and cable standard named on the unit, then use output labels and cost to sort the close choices. The listed-price range has a USD 65 spread from lowest to highest. These four choices include an SFX designation, two 1000W names, and PCIe 5.0/ATX 3.0-focused models. Treat the different wattage figures as neutral labels rather than a performance ranking.
Listed-price comparison
| Power supply | Listed price | Price scale |
|---|---|---|
| ATX 1000W Full Modular Power Supply with ARGB Fan | USD 86.10 | |
| MSI MPG A1000G PCIE 5.0 & ATX 3.0 | USD 130.00 | |
| Segotep 850W ATX 3.0 PCIe 5.0 | USD 99.99 | |
| Silver Stone SST-ST45SF 450W SFX | USD 65.00 |
Decision matrix
- Need a 1000W name plus an ARGB fan: The ATX 1000W Full Modular Power Supply puts both details together.
- Shopping specifically for PCIE 5.0 and ATX 3.0 wording: MSI MPG A1000G carries both in its name.
- Seeking a named Native 12VHPWR Cable: Segotep calls this out directly.
- Starting with an SFX designation: Silver Stone SST-ST45SF is the direct match among these four.
Product notes
ATX 1000W Full Modular Power Supply with ARGB Fan
The attraction here is the combination of a 1000W label, full modular design, and ARGB fan in one unit. Its modular layout is also presented around cleaner cable management, which makes it a sensible direction for a shopper who wants to organize the interior of an ATX-oriented build. The listed connectors include 20+4 Pin and 4+4 CPU. Its limitation is the form-factor distinction: it is marked ATX, making it a different format choice from the Silver Stone unit that explicitly carries SFX wording.
MPG A1000G PCIE 5.0 & ATX 3.0 Gaming Power Supply - Full Modular - 80 Plus Gold
MSI MPG A1000G is the direct pick when PCIE 5.0 and ATX 3.0 language is central to the shortlist. It combines those labels with a full modular design and an 80 Plus Gold designation. The named connector selection is broad, including 4+4 CPU, 4 Pin Peripheral, 6+2 Pin PCI Express, 24 Pin, and SATA I. This is also the highest-listed-price choice at USD 130.00, so its specific connection list and named standards need to be meaningful to your build plan rather than incidental preferences.
Segotep 850W ATX 3.0 Gaming Power Supply PCIe 5.0 Full Modular 80 Plus Gold PSU
Choose the Segotep when a Native 12VHPWR Cable is a key requirement. It explicitly identifies that cable and says it can provide up to 600W to PCIe 5.0 graphics cards; it also pairs ATX 3.0 and PCIe 5.0 wording with flat black cables and a full modular layout. That creates a focused cable-and-standard proposition without requiring a jump to the highest listed price. For shoppers with a Gold color preference, however, the finish is a limitation: this Segotep is listed in Black, while the MSI is listed in Gold.
Silver Stone SST-ST45SF 450W SFX 80 Plus Bronze Power Supply
Silver Stone SST-ST45SF is the clear starting point for a shopper whose decision begins with the SFX designation rather than an ATX or ATX 3.0 label. Its 450W and 80 Plus Bronze wording are straightforward, and its USD 65.00 price is the lowest in the comparison. Condition is the important trade-off here. This unit is listed as used, and the item description notes signs of scratches from prior use. That makes it a distinct choice from the three new-condition supplies, rather than a direct like-for-like substitute based on price alone.
Final recommendation by use case
Choose the ATX 1000W Full Modular Power Supply with ARGB Fan when 20+4 Pin and 4+4 CPU are the named connections you are choosing around. Pick the MSI MPG A1000G when a 1000W designation paired with 80 Plus Gold matters most. The Segotep fits a USD 99.99 target for a PCIe 5.0/ATX 3.0-focused supply. Select the Silver Stone SST-ST45SF when USD 65.00 and the SFX designation outweigh the used condition.
