Intel Arc A750 power connector: what does it need?
The Intel Arc A750 needs 1× PCIe 8-pin + 1× PCIe 6-pin from the power supply. At about 225 W board power, here is what to know before you plug it in.
Recommendations are planning estimates, not electrical or purchasing advice. The hardware figures behind them are vendor-published; your exact board-partner model and build can still differ.
Power connector
1× PCIe 8-pin + 1× PCIe 6-pin
Reference power input.
GPU board power
225 W
Vendor TGP/TBP — a conservative ceiling, not typical gaming draw.
PSU minimum (typical build)
550 W
Assumes a 125 W-class CPU + standard accessories.
PSU comfortable (typical build)
650 W
Standard headroom for spikes and future room.
Board-partner note
Intel Limited Edition reference design (shown); many partner cards use 2x 8-pin.
ATX 3.x advice
A classic multi-8-pin quality PSU works for this card. An ATX 3.x unit is still a sensible buy for its transient-load headroom, but it is not required.
Safety notes
- Run a separate PSU cable to each 8-pin input on the card rather than one daisy-chained (pigtail) cable, keeping per-cable load conservative.
- Never mix modular cables between different PSU brands or models. The PSU-side pinout is not standardized — a mismatched cable can destroy hardware.
- Do not exceed a cable's rated load with splitters or adapters, and replace any cable with damaged or discolored connectors.
- Before buying, confirm the connector layout and PSU guidance on the official pages of both your exact card model and your PSU — board partners change designs between variants.

How to check this figure
Intel's ARK page for this card publishes a Total Board Power but no PSU figure. The 600 W comes from Intel's Arc Desktop Quick Start Guide (support article 000091128), which names the A750 Limited Edition alongside the A770 Limited Edition on one line: "Minimum 600W power supply with two PCIe power connectors - 1x8-pin & 1x6-pin".
