EVGA 750 BQ 750W 80+ Bronze Semi-Modular Power Supply: specs and fit

The EVGA 750 BQ (model 110-BQ-0750-V1) is a 750-watt power supply for desktop PCs. It converts mains electricity into the lower voltages that a motherboard, graphics card and drives use. It is 80 PLUS Bronze certified, semi-modular, and carries a five-year warranty, according to EVGA.

What 750 watts means

The wattage is the maximum continuous power the unit can deliver to the parts inside the computer. It does not mean the PC always draws that much. A system draws only what its components need, so a larger supply simply has headroom. A 750W unit typically suits a mid-range to fairly powerful gaming PC, but the right size depends on your processor and graphics card. Check the power recommendations from your graphics card's maker and add some margin.

What 80 PLUS Bronze tells you

80 PLUS is a certification for efficiency. EVGA says the 750 BQ reaches 85% efficiency or higher under typical loads. That means that at the wall, roughly 85% or more of the power drawn becomes usable power for the computer, with the rest lost as heat. Higher tiers, such as Gold and Platinum, reach higher efficiency, but Bronze is a common baseline for mainstream builds.

Semi-modular cabling

In a semi-modular unit, some cables are fixed to the supply (usually the main motherboard connector) while the others plug in only when needed. That cuts clutter inside the case and makes airflow easier. Exact connector counts are not in the listing, so check the manual or the EVGA product page to confirm there are enough PCIe, SATA and CPU connectors for your build.

Fan and noise

The unit has a 140mm fan with a Teflon nano steel bearing. EVGA calls the fan quiet and intelligent, and says the automatic fan control gives near silent operation. In general, larger fans can turn more slowly for the same airflow, which reduces noise, and many supplies keep the fan very slow or stopped at low loads.

Built-in protections

The listing names five protections, which are common on quality supplies:

• OVP, over voltage protection
• UVP, under voltage protection
• OCP, over current protection
• OPP, over power protection
• SCP, short circuit protection

These are meant to shut the supply down if something goes outside safe limits. Follow the manual when installing and connecting power, and don't open a power supply, since capacitors can hold a charge.

Power On Self Tester

EVGA includes a Power On Self Tester with this model. It lets you check whether the supply starts and produces power without connecting it to a motherboard, which is handy when troubleshooting a PC that will not turn on.

Who it suits

It suits people building or upgrading a desktop who want a 750W supply with a standard efficiency certification, a quiet fan and a manageable cable layout. It is a general-purpose ATX supply and not a specialist unit for very high-end multi-graphics-card systems.

What to check before you buy

• Wattage: compare your parts' recommended power with 750W, leaving some headroom.
• Connectors: confirm you have the PCIe power connectors your graphics card needs.
• Case fit: check that your case takes a standard ATX supply of this length.
• Mains supply: confirm the unit supports your country's voltage, as listed in the manual.
• Cable length: check the cables reach your parts in a larger case.
• Warranty: read the terms for five-year coverage.

The short version

• 750W ATX power supply, 80 PLUS Bronze, 85% efficiency or higher at typical loads.
• Semi-modular cabling and a 140mm fan built for quiet operation.
• Protections: OVP, UVP, OCP, OPP and SCP.
• Includes a Power On Self Tester and a five-year warranty.
