Apevia Prestige 800W 80 Plus Gold ATX Power Supply: specs and fit

The Apevia Prestige 800W is a standard ATX power supply for desktop PCs. It is rated 80 Plus Gold, uses a 135mm fan and has the connectors a gaming build typically needs. Because the power supply feeds every other part, it is worth understanding its figures before you match it to a build.

What 800W and 80 Plus Gold mean

The 800W figure is the total power the unit is built to deliver. A system uses only what its parts draw, so a bigger number doesn't mean more electricity is always consumed; it means more headroom for a powerful graphics card or several drives.

80 Plus is a certification of efficiency, showing how much of the power drawn from the wall reaches the computer as opposed to being lost as heat. Gold is a higher tier than Bronze or Silver. In general, a more efficient unit wastes less energy and runs cooler. Apevia lists this model as 80 Plus Gold certified and RoHS compliant, meaning it follows restrictions on certain hazardous substances.

Design and power delivery

Apevia describes a DC-to-DC converter design that it says provides stronger dynamic response, greater system stability and better use of the 12V DC rail. In modern PCs, the processor and graphics card draw mainly from 12V, so the strength of that rail is the figure that matters most. The listing says the unit supports a single 12V output for higher power use, and active PFC (power factor correction), which makes the unit draw power from the wall more efficiently.

It supports dual-, quad- and multi-core CPUs.

Connectors

The listed connectors are:

• 1 x 20/24-pin main power
• 1 x 4/8-pin 12V (for the CPU)
• 2 x PCI Express 6+2-pin (for graphics cards)
• 7 x SATA
• 4 x peripheral

Apevia says the 6-pin and 8-pin PCI-E connectors support all GPU platforms and multi-GPU technologies. Two PCI-E connectors are enough for many single-card builds, but a card that needs three should be checked against this count.

Cooling and protections

A single 135mm fan, which Apevia describes as auto-thermally controlled, adjusts its speed to temperature. Larger fans can generally move air at lower speeds, which usually means less noise. The listing says "all protections" are included, without naming them. Check the manual or the manufacturer for the exact list.

Size, weight and warranty

The unit measures about 6.2 x 5.9 x 3.4 inches (15.7 x 15 x 8.6 cm) and weighs about 4.7 lb (2.1 kg). Apevia lists a three-year warranty.

Who it suits

It suits builders and upgraders putting together or refreshing a mid-to-high-power ATX desktop who need an 800W unit with Gold-tier efficiency and a conventional, non-modular style set of connectors.

What to check before you buy

• Power needs: add up your CPU and graphics card requirements, with some headroom.
• Graphics card connectors: confirm the 6+2-pin count matches your card.
• Case fit: check that your case takes a standard ATX power supply of this size.
• Cabling: the listing doesn't say whether cables are modular, so check that the cable lengths reach your parts.
• Model name: the listing shows both PR800W and RP800W, so confirm the exact model.
• Fitting: switch off and unplug before installation, and follow the manual.

The short version

• 800W ATX power supply, 80 Plus Gold and RoHS compliant, with active PFC.
• Single 12V output and a DC-to-DC converter design.
• 2 x PCI-E 6+2-pin, 7 x SATA and 4 x peripheral connectors.
• 135mm auto-thermal fan; three-year warranty.
