Pros & Cons

Pros

✓ Native 12VHPWR cable pushes 600W to one RTX 40/50 Series card, no adapter octopus
✓ ATX 3.1 spec handles 300% GPU power excursion, so transient spikes don't trip OPP
✓ 80 PLUS Gold at 91.8% typical-load efficiency cuts case heat
✓ Japanese electrolytic capacitors on a full-bridge LLC + DC-DC topology
✓ Fully modular cabling: run only the 2x PCIe 4.0 and 1x PCIe 5.1 leads you need

Cons

✗ 750W ceiling is tight for an RTX 4090/5090 paired with a high-TDP CPU
✗ Only 3 total PCIe outputs, limiting multi-GPU or heavily split-rail builds
✗ Segotep has less North American RMA presence than Corsair or Seasonic
✗ 120mm FDB fan is smaller than the 135-140mm fans on rival Gold units

Manufacturer description

Its native 12VHPWR cable delivers up to 600W to a single PCIe 5.1 graphics card, so an RTX 40 or 50 Series GPU runs off one clean cable instead of a three-headed adapter. Segotep rates the platform to absorb 200% total power excursion and 300% GPU power excursion, which is what keeps a modern card's transient spikes from tripping the over-power protection mid-benchmark. The 80 PLUS Gold certification translates to 91.8% efficiency at typical load, so less of your wall draw turns into case heat. Inside, Japanese electrolytic capacitors handle the ripple; outside, a 120mm fluid-dynamic-bearing…

SpecPicks Verdict

SpecPicks scored Segotep 750W Power Supply using a rating × review-volume × price-fit model applied to published specs and reviews across the power supplies category. Segotep's power supplies lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for power supplies of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

Is 750W enough for an RTX 4070 Ti or RTX 5070?

Yes. Those cards sit well inside a 750W budget, and the native 12VHPWR cable feeds them directly at up to 600W. For an RTX 4090 or 5090 alongside a high-TDP CPU, size up.

Does it include a 12VHPWR cable or do I need an adapter?

It ships with a native 12VHPWR cable rated to 600W for PCIe 5.1 cards. No 8-pin-to-12VHPWR adapter is required for RTX 40 and 50 Series GPUs.

Will it work with older RTX 20 and 30 Series cards?

Yes. Two PCIe 4.0 ports cover NVIDIA RTX 20/30 Series and AMD graphics cards, in addition to the separate PCIe 5.1 port for newer GPUs.

How loud is the 120mm fan under gaming load?

It uses a fluid-dynamic-bearing 120mm fan, which runs quieter and lasts longer than sleeve-bearing designs. Segotep does not publish a dBA figure, so check the listing for current acoustic specs.

What does ATX 3.1 with 300% power excursion actually mean for me?

Modern GPUs draw brief spikes far above their rated wattage. This unit tolerates 200% total and 300% GPU excursion, so those spikes don't trigger a protection shutdown mid-game.
