Ideal for fleets needing a reliable spare that supports mid-tier GPU upgrades and multiple SATA drives without case modification. Not for builders using standard ATX cases, proprietary small-form-factor chassis outside the listed models, or systems requiring modular cabling.

Sustained 500W output

Thermally regulated fan and industrial-grade capacitors maintain stable delivery during 24/7 operation. Built-in OVP, OCP, SCP and OTP circuits protect components under continuous load, while universal 100-240V input ensures consistent performance across regions.

Questions about this item

Will this 500W SFX-L PSU fit the existing mounting holes in my Optiplex 5070 MT?

Yes, it matches the original SFX-L dimensions and mounting points for Optiplex 5070, 7070, 5080, 7080, 5090, 3650, 3670, 3671, 3260 and 3681 MT towers.

Can I keep my current motherboard and CPU power cables when swapping to this unit?

No, the PSU has a fixed cable set with a 6-pin motherboard connector, dual 4-pin CPU connectors and 6+8-pin PCIe leads that plug directly into the board.

How do I verify the PSU is delivering stable power after installation?

The system should boot normally, the fan will run at a low speed under idle load and the built-in OVP, OCP, SCP and OTP circuits protect components from surge or overload.
