Question 1

ASUS Prime AP-750G vs Corsair RM750e: which should I buy?

Accepted Answer

Choose the ASUS Prime AP-750G when you want a native 16-pin PCIe cable, an 8-year warranty, and a 150 mm ATX power supply at a competitive price. Choose the Corsair RM750e when a shorter 140 mm unit, zero-RPM fan operation, or additional SATA and peripheral connectors are more important. Both provide 750W capacity, full modular cabling, and 80 PLUS Gold efficiency.

Question 2

Should I buy the ASUS Prime AP-750G or the ASUS Prime AP-850G?

Accepted Answer

Buy the AP-750G for a mainstream gaming PC that fits comfortably within a 750W power budget. Choose the AP-850G if you are pairing the system with a higher-power graphics card, a power-intensive processor, or want 100W of additional capacity for future upgrades. The two models use the same 150 x 150 x 86 mm chassis, similar connector layouts, ATX 3.x support, and 8-year warranties, so the main difference is available power headroom.

Question 3

Is the ASUS Prime AP-750G a better upgrade than a 650W Gold PSU?

Accepted Answer

The AP-750G is the better upgrade when your planned graphics card or processor needs more power headroom, because it adds 100W of rated capacity and includes a native 16-pin PCIe cable for compatible modern GPUs. A 650W Gold PSU remains suitable for a lower-power system when its continuous load and graphics-card requirements are comfortably within 650W. The upgrade is most useful for newer or upgrade-focused gaming PCs rather than systems with modest, fixed power demands.

Question 4

Is the ASUS Prime AP-750G suitable for a small-form-factor PC?

Accepted Answer

Choose the AP-750G for a compact ATX or microATX build only when the case accepts a standard ATX power supply with 150 mm of clearance. For an SFF case designed around SFX power supplies, choose an SFX model such as the Corsair SF750 instead. The AP-750G provides 750W and full modular cabling, but its standard ATX dimensions are substantially larger than an SFX unit.

Question 5

Is the ASUS Prime AP-750G worth choosing over a premium 750W PSU?

Accepted Answer

Choose the AP-750G when price, ATX 3.x support, full modular cabling, quiet operation at low and medium loads, and an 8-year warranty are the priorities. A premium 750W model is the better fit when independent testing shows tighter ripple suppression, higher-end internal components, or a longer warranty at a price you are willing to pay. Tom's Hardware measured strong voltage regulation and Gold-level efficiency for the AP-750G, while noting that its ripple performance and component selection were not at premium-tier levels.

Question 6

Is 750W enough for a gaming PC or workstation?

Accepted Answer

It can be suitable for a system whose total power requirement fits within 750W. The ASUS Prime 750W Gold provides up to 62A on the +12V rail and includes one native 16-pin PCIe cable for compatible newer graphics cards. Check the processor, graphics card, and system manufacturer's recommended PSU wattage before buying; high-power GPUs may require more capacity or additional headroom.

Question 7

Does it support newer graphics cards with a 16-pin PCIe power connector?

Accepted Answer

Yes. The power supply is ATX 3.0 compatible and includes one native PCIe Gen 5 16-pin cable, plus an additional 16-pin-to-dual-8-pin cable. This can simplify installation for graphics cards that use a compatible 16-pin input, but the graphics card's required wattage and connector configuration should still be verified.

Question 8

Will it fit in my PC case?

Accepted Answer

The ASUS Prime 750W Gold measures 150 x 150 x 86 mm and uses a standard ATX12V form factor. It should fit cases that support a standard ATX power supply with at least 150 mm of PSU length, but case-specific clearance can vary because of drive cages, cable space, and mounting design. Confirm the case manual or specifications before purchase.

Question 9

Does it include all the cables needed for a new PC build?

Accepted Answer

Yes. It includes a 24-pin motherboard cable, two CPU cables, one native 16-pin PCIe cable, one 16-pin-to-dual-8-pin PCIe cable, one additional PCIe cable, SATA cables, a peripheral cable, and a power cord. Because modular PSU cables are not universally interchangeable, use the cables supplied with this power supply rather than cables from another PSU.

Question 10

Is it quiet and suitable for a long-term build?

Accepted Answer

It is designed for durability and airflow rather than guaranteed silent operation. The unit uses a 135 mm Axial-tech fan and dual ball-bearing construction, which ASUS states can last up to twice as long as sleeve-bearing designs. It also includes an 8-year warranty. Actual noise depends on system load, room temperature, case airflow, and fan behavior; no specific noise rating is provided in the supplied specifications.

Question 11

Is the ASUS Prime 750W Gold enough for a modern gaming PC?

Accepted Answer

It is suitable for many mainstream gaming PCs, including systems using mid-to-upper-range GPUs, but 750W may provide limited headroom for high-power cards such as the RX 7900 XTX or some RX 9070 XT configurations. Check the complete system power estimate; an 850W unit is the safer choice for demanding GPUs, overclocking, or future upgrades.

Question 12

Can the ASUS Prime 750W Gold power a graphics card with a 16-pin connector?

Accepted Answer

Yes. The power supply is ATX 3.0 compatible and includes a native PCIe 16-pin cable for compatible PCIe Gen 5 graphics cards. Use the supplied ASUS cable, connect it fully, and avoid mixing modular cables from another power supply.

Question 13

Is the ASUS Prime 750W Gold worth buying over another 750W power supply?

Accepted Answer

It can be a reasonable choice when priced competitively, especially if you want full modular cabling, 80 Plus Gold efficiency, ATX 3.0 support, and an 8-year warranty. If competing models such as the Corsair RM750e or MSI MAG A750GL cost less, community discussions commonly favor comparing platform quality, warranty, noise, and included connectors rather than choosing the ASUS solely by brand.

Question 14

Will the ASUS Prime 750W Gold fit well in a compact PC case?

Accepted Answer

The 150 mm PSU length is standard for many ATX cases but may leave less cable-routing space than a 140 mm model. Its fully modular design reduces unused cables, but you should verify the case's PSU-length clearance and available space behind the motherboard tray before buying.
