Read those reviews before purchase !
Agreed. Per the SPL PSU Tier List[google.com], it's rated A-, which is very good. However, what is odd about it is the following:

:
Mediocre load regulation on the minor rails, and poor excursion response in the 200% test. The OCP and OPP triggering points are set too high on all rails. 1000W model has high inrush currents. Good performance otherwise.
Not sure I would trust this with a high current GPU (basically anything that uses 12VHPWR).

Agree. For a lower tier system with a x050 or x060 card it might be fine, but I would shy away from this for anything with a x070+ GPU (or equivalent intel/amd card). Best to go with the tried and true titans to protect the most crucial and pricey part of your build.
let me sum them up the 2 one stars were some poor guy that got an opened unit and the other was a moron that didn't wire his system correctly or overloaded a rail and got it to send some smoke signals the rest were fine I have put PSUs from this supplier up against the best and it's comparable. Also Cybernetics doesn't Platinum certify garbage... if you spend too much time reading them this will be gone they are low on stock from what I understand (may or may not have insiders in purchasing at Amazon) bottom line if you have a 5080 or 5090 I would feel comfortable using this brand but let's be realistic if your looking for a budget power supply with a $1500 GPU I think you have more problems than just this decision. just my . 02c as a professional PC builder with 25 years doing it! Thanks everyone!

Inrush current has nothing to do with how much power/current a GPU is drawing from a PSU.
Inrush currents only exist when the the power switch on the PSU is turned on (not the computer power button). When you turn off the power to your PC with the regular power button, it's actually not fully off since the capacitors inside the PSU stay charged and it draws (very little) power from the outlet to keep them charged. When you turn your PC on again using the PC power button there is no inrush current. When you actually turn your pc off from the PSU and then turn it on from there, that's when "inrush currents" happen, that current refers to the current between the AC plug in the power supply through whatever circuitry it goes through up to the capacitors inside. High inrush current means that's high when turning it on while it charges its capacitors. The worst it can do is fry some internal psu components if you do it a bunch of times in succession I guess, but that is not something that should happen.
Also the really high inrush currents are when this PSU is on 230V at 70 Amps. At 115V it's only 32 Amps. For reference A-tier MSI MAG A1000G has 25A inrush current at 115V and 52A at 230V.
Unless you continously use the psu power switch, inrush currents are not something to be worried about. The warranty is the more important part, so if you think this PSU is a bad deal, base it on the warranty period.

How to show to the world you know nothing about power supplies or building a system.

Yes — a Cybenetics‑certified PSU is more trustworthy than one that only has 80 Plus, because Cybenetics tests far more than efficiency.
Here's the short version:
> 80 Plus = efficiency only
> Cybenetics = efficiency + noise + ripple + thermals + real‑world load behavior [How-To Geek](https://www.howtogeek.com/what-ar...ey-matter/) [LinkedIn](https://www.linkedin.com/pulse/80...afiz-zfxic)
---
# ✅ Why Cybenetics is more trustworthy
Cybenetics certification is considered the most rigorous PSU testing standard available today because it measures:
### 1. Efficiency (ETA rating)
- Diamond, Titanium, Platinum, Gold, Silver, Bronze
- Tested from 5% to 100% load, not just 20/50/100% like 80 Plus
- Tested at realistic temperatures (30°C) instead of the cooler lab temps used by 80 Plus [darkFlash](https://www.darkflash.com/article...cybenetics)
### 2. Noise (LAMBDA rating)
- A++ (silent) down to Standard (loud)
- Tested in a 6 dB silent chamber for accuracy [darkFlash](https://www.darkflash.com/article...cybenetics)
### 3. Additional electrical behavior
Cybenetics also evaluates things 80 Plus completely ignores:
- Voltage ripple
- Transient response
- Power factor
- Standby efficiency
- Vampire power draw
[How-To Geek](https://www.howtogeek.com/what-ar...ey-matter/) [Reddit](https://www.reddit.com/r/hardware..._the_next/)
These are critical for GPU stability — especially with modern GPUs that have huge transient spikes.

# ✅ Why 80 Plus is less trustworthy today
80 Plus:
- Only measures efficiency, nothing else
- Uses outdated test methods
- Does not test ripple, noise, thermals, or transient spikes
- Can be "gamed" by manufacturers using cheaper components while still passing efficiency tests
[LinkedIn](https://www.linkedin.com/pulse/80...afiz-zfxic)
This is why many brands have been quietly downgrading internal quality while still advertising "Gold" or "Platinum."
[Reddit](https://www.reddit.com/r/hardware..._the_next/)

# 🔥 Bottom line
If a PSU is Cybenetics‑certified, it means:
- It was tested more thoroughly
- It passed stricter standards
- It gives you real data about noise, ripple, and stability
- It's harder for brands to fake or cheat
So yes — Cybenetics certification is more trustworthy than 80 Plus.
The reactions are amusing to any brand that is not well-known when in fact SAMA (the actual manufacturer for many "big" brands) has a Platinum cert.
If slapped a Corsair sticker and listed it for $50 more, they would consider it a better deal. They don't know that SAMA builds for Lian Li or Fractal. They don't know that SAMA is an "OEM powerhouse."
The "intel" is clear: they are a manufacturing giant that has provided the physical logistics, regional agency, and OEM pipelines for brands like Lian Li and Fractal Design.
SAMA is the manufacturer for brands. They are simply cutting out the middleman. When you buy SAMA, you are buying the hardware without the "Big Brand" marketing tax.
The SAMA XP/P-Series is already landing in Tier A/B on high-fidelity lists (like Cultists) and getting Cybenetics Platinum certs.
The Slickdeals nodes will happily pay a $50–$100 "tax" for a sticker, but when you show them the SAMA XP Platinum (the raw, high-fidelity source code), they downvote it because they don't recognize the name.
They think they are buying "elite" engineering from big names, they are often just buying SAMA's hardware with a different "render" (label) on the box.
SAMA is a massive OEM/ODM powerhouse.
1. SAMA is not a boutique case shop — they're an OEM/ODM backbone
They've been a manufacturing node for:
Lian Li
Fractal Design
Multiple regional white‑label PSU lines
Various chassis and PSU suppliers in APAC
This isn't speculation — it's how the industry works. Most "brands" are marketing, logistics, and support layers sitting on top of a handful of factories.
2. Their XP/P-Series PSUs
The XP Platinum units:
Use 105°C Japanese capacitors
Have Cybenetics Platinum ratings
Land in Tier A/B on independent lists
Are built on platforms comparable to mid/high-end Corsair and Seasonic units
This is not what a "random case brand" produces. This is what an OEM with real electrical engineering capability produces.
3. People confuse "brand identity" with "engineering capability"
This is the real psychological choke point.
To them:
Corsair = safe
Seasonic = safe
EVGA (back in the day) = safe
SAMA = unknown = unsafe
But the engineering reality is:
Many "big brands" outsource to the same factories
The PSU tier lists are based on platform quality, not logos
SAMA's high-end units are objectively competitive
They're reacting to branding, not hardware.
