Apevia vs ASRock PSU Comparison
Form factor and size
The Apevia TFX-AP300W uses a TFX form factor, measuring 3.23 x 2.5 x 6.75 inches. This compact design fits small form factor cases. The ASRock Phantom Gaming PG-750G follows standard ATX dimensions at 5.91 x 3.39 x 5.91 inches. You must choose the shape that matches your case. TFX units save space in tight builds. Standard ATX units fit most mid-tower and full-tower chassis. Your case determines which physical size works for you.
Wattage output
The Apevia unit provides 300W of total power. It delivers +3.3V at 12A, +5V at 12A, and +12V at 20A. This output suits low-power systems or basic office builds. The ASRock unit offers 750W of total power. It is designed for high-performance components. You need significantly more wattage for gaming rigs or workstations with powerful GPUs. The ASRock provides more than double the power capacity of the Apevia.
Efficiency rating
The ASRock PSU holds an 80 PLUS Gold certification. It claims 90% efficiency, which is 2% higher than the standard Gold requirement. This means less wasted energy as heat. The Apevia specifications do not list an 80 PLUS efficiency rating. Without this certification, you cannot verify its energy conversion performance. Higher efficiency reduces electricity costs and operating temperatures. The ASRock clearly leads in verified energy efficiency standards.
Modularity
The ASRock Phantom Gaming is a fully modular power supply. You connect only the cables you need, using individual braided pattern cables. This reduces clutter inside your case. The Apevia TFX-AP300W is a standard non-modular unit. All cables are fixed and permanently attached. You must route all cables even if you do not use them. Full modularity offers cleaner builds and better airflow management. The ASRock provides superior cable management options.
ATX version and PCIe
The ASRock unit supports the ATX 3.1 standard. It includes a PCIe 5.1 cable with a 12V-2x6 connector. This supports modern graphics cards with direct power delivery. The Apevia specifications do not mention an ATX version or PCIe connector type. It uses standard output rails. If you have a new GPU, the ASRock provides the necessary native connection. The older Apevia may require adapters for latest hardware.
Warranty coverage
The ASRock Phantom Gaming comes with a 10-year global warranty. This long coverage period indicates manufacturer confidence in component quality. The Apevia TFX-AP300W specifications do not list a warranty duration. You cannot confirm the length of support or replacement policy from the provided data. A decade of coverage protects your investment against early failures. The ASRock offers a significantly longer and clearer warranty term.
