Excellent
Consensus
Compare
Ranked #1 based on expert reviews, user sentiment, and value analysis.
Pros
- Native 12VHPWR cable included
- Zero-RPM fan mode
- 10-year warranty
Cons
- Gold efficiency, not Platinum
- Cables are stiff and hard to route
Don't buy this if…
- The included 12VHPWR cable is proprietary to Corsair; do not use cables from other PSU brands as they have different pinouts.

9.2
Excellent
Consensus
Compare
Ranked #2 based on expert reviews, user sentiment, and value analysis.
Pros
- Compact 140mm depth
- Tight voltage regulation
- 10-year warranty
Cons
- No native 12VHPWR cable
- Fan can be audible under full load
Don't buy this if…
- Does not include a 12VHPWR connector; you will need an adapter for RTX 4000 series GPUs, which adds cable clutter.
#3
9.0
Excellent
Consensus
Compare
Ranked #3 based on expert reviews, user sentiment, and value analysis.
Pros
- Platinum efficiency saves energy
- Near-silent operation
- Native 12VHPWR connector
Cons
- Premium price
- Large 160mm depth
Don't buy this if…

8.7
Excellent
Consensus
Compare
Ranked #4 based on expert reviews, user sentiment, and value analysis.
Pros
- Compact 150mm depth

#5
8.5
Excellent
Consensus
Compare
Ranked #5 based on expert reviews, user sentiment, and value analysis.
Pros
- ATX 3.0 with native 12VHPWR
- Competitive pricing
- Zero-fan mode under 30% load
Cons
- Fan noise noticeable at full load
- Cable quality feels average
Don't buy this if…

#6
8.3
Good
Consensus
Compare
Ranked #6 based on expert reviews, user sentiment, and value analysis.
Pros
- SFX form factor for compact builds
- Platinum efficiency
- Excellent voltage regulation
Cons
- Limited cable length for ATX cases
- Expensive for 750W
Don't buy this if…
- SFX cables are shorter than ATX standard; if used in a full-size case with an SFX adapter bracket, you may need cable extensions.
#7
8.1
Good
Consensus
Compare
Ranked #7 based on expert reviews, user sentiment, and value analysis.
Pros
- Dual 12VHPWR connectors
- Digital power monitoring
- 1300W headroom
Cons
- Very expensive
- Overkill for most builds
Don't buy this if…
- 1300W is far more than most single-GPU builds need; a 850W or 1000W unit is sufficient unless you are running extreme overclocks.
#8
7.9
Good
Consensus
Compare
Ranked #8 based on expert reviews, user sentiment, and value analysis.
Pros
- 850W in SFX form factor
- Semi-fanless operation
- Fully modular
Cons
- Fan can whine at high loads
- Short cables for larger cases
Don't buy this if…
- SFX cable lengths are designed for compact enclosures; in a standard ATX mid-tower, you will likely need extension cables.
