What happened
Tom's Hardware reviews the Phanteks AMP GH 750W power supply, priced under $90, noting strong 12V regulation, low ripple, and Japanese capacitors, but flagging a 450W cap on its 12V-2x6 connector as a limitation for high-power GPU setups.
Why it matters
Only relevant if you are building or upgrading a local AI workstation or homelab with a power-hungry GPU; the 450W cap on the 12V-2x6 connector means this PSU may not support upcoming high-end graphics cards that draw more than 450W via that connector, despite the 750W total rating.
Discussion angle
Whether the 450W 12V-2x6 cap matters for local AI inference rigs running consumer GPUs like RTX 4090/5090, or if builders should just avoid this PSU for future-proofing.
