850 W ATX 3.1 Power Supply
The ASRock PRO-850B is an 850 W ATX 3.1 compatible power supply with 80 PLUS Bronze certification. It uses a single 120 mm fan and measures 140 mm in length. A full suite of protections including OCP, SCP, OVP, UVP, OTP and OPP is built in. The unit carries a three-year manufacturer warranty.
For Value-Focused Builds Needing PCIe 5.1
This unit suits builders who want a native 12V-2x6 connector for modern graphics cards and dual-colour cables that confirm a secure fit. It is not for systems that require more than one EPS 12V CPU connector or more than two 6+2-pin PCIe connectors. Buyers needing higher efficiency ratings or additional peripheral connectors should look at other options.
Check Clearance and Connector Counts
Verify that your case accepts a power supply up to 140 mm long and 150 mm wide. Confirm the motherboard needs only one 4+4-pin CPU power connector. Ensure the graphics card can run from a single 12V-2x6 connector or the two 6+2-pin leads provided. Count SATA and 4-pin peripheral devices against the four and two ports available.

Küsimused selle toote kohta
Does this PSU include a native 12V-2x6 PCIe 5.1 connector for modern GPUs?
Yes, it ships with one PCIe 5.1 12+4-pin dual-colour cable rated for the 12V-2x6 standard.
Will the 140 mm depth fit inside my existing ATX case?
The unit measures 140 mm deep, so any case that accepts standard ATX power supplies up to that length will accommodate it.
How can I confirm the 24-pin and EPS cables are fully seated after installation?
The motherboard and CPU connectors use ASRock Classic Green housings that make a visible colour change when the latch clicks into place.
