Manufacturer description

The Gigabyte P650B (model GP-P650B, part 28200-p650b-1eur) is a 650W ATX power supply built for mid-range gaming and workstation builds where you need headroom for a single mid-tier GPU plus a modern CPU without overspending on the PSU.

SpecPicks Verdict

SpecPicks scored Gigabyte 28200-p650b-1eur using a rating × review-volume × price-fit model applied to published specs and reviews across the power supplies category. GIGABYTE's power supplies lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Frequently Asked Questions

Is 650W enough for my gaming PC?

650W suits most builds pairing a mainstream 6-core or 8-core CPU with a single mid-range graphics card. If your GPU maker specifies a 750W or larger supply, step up instead of stretching this unit.

What exactly am I buying under all these part numbers?

This is the Gigabyte P650B, 650W ATX, in black. Gigabyte's model code is GP-P650B, the distributor part number is 28200-p650b-1eur, and the EAN barcode is 4719331550295.

Will this fit my case?

It is a standard ATX power supply unit, so it mounts in any case with a conventional ATX PSU bay. Confirm your case is not SFX or TFX-only before ordering.

Is it modular, and what warranty does Gigabyte offer?
