Questions about this item

Will this unit fit a standard ATX case and connect to a modern motherboard?

The power supply follows the ATX12V / EPS12V form factor with a 24-pin main connector, a 4+4-pin CPU connector, two 6+2-pin PCIe connectors and four SATA power connectors for drives.

What does the 80 PLUS Bronze rating mean for daily power use?

The unit is certified to reach at least 85% efficiency at typical loads, so less electricity is wasted as heat and the fan can run more quietly.

Is the +12V rail strong enough for a dedicated graphics card?

A single +12V rail rated at 35A delivers up to 420W on the 12V line, which is the rail that feeds the GPU and CPU.
