Capacity and certification

The TOPOWER TOP-700WB1 delivers 700 W of continuous power through an ATX12V and EPS12V design. It carries 80 PLUS Bronze certification and uses Active PFC across a 100-240 V input range. The unit suits mid-range gaming PCs and workstation builds that need reliable output without modular cables.

Connector and clearance check

Verify that your motherboard accepts a 20+4 pin main connector and that the graphics card requires no more than one 6 pin and two 6+2 pin PCIe leads. Eight SATA power plugs are provided for drives and peripherals. The power supply measures 160 mm in depth, so confirm the case allows at least that length.

Non-modular upgrade path

This model replaces older non-modular units that lack 80 PLUS Bronze efficiency or sufficient PCIe connectors for dual-card SLI and CrossFire setups. The jump is worthwhile when moving from a lower-wattage design that cannot sustain 700 W or lacks Active PFC and Haswell-ready standby support.

Questions about this item

What cables come attached to the TOPOWER TOP-700WB1 and what must I add?

The unit has a fixed 20+4 pin main connector, one 6 pin and two 6+2 pin PCIe connectors, and eight SATA power connectors. No modular cables are included because the PSU is non-modular.

Which version of the TOP-700WB1 should I pick for a build that needs 700 W?

This model is a single 700 W ATX12V/EPS12V unit with 80 PLUS Bronze certification and active PFC; there are no alternative capacities or versions listed.

What does the 700 W rating mean when the PSU is installed in a PC?

It can deliver up to 700 W of continuous DC power across all rails while meeting 80 PLUS Bronze efficiency at 100-240 V input, protected by over-voltage and overload circuits.
