ASRock do not send out many power supplies for review, so I was interested to see what they were releasing in 2025. The Phantom Gaming PG-1000G is certainly no slouch and has held up well during the last week of testing in our labs. I can't say I am a huge fan of the branding and having a massive ‘PG' sticker on the sides of the unit, but they are minor quibbles.

Technically this PG-1000G is capable of coping with high power demand and would be an ideal partner for a new Nvidia RTX 50 series GPU in 2025 – perfect for something like an overclocked RTX 5080. Let me digress a minute …

… The Nvidia RTX 5090 Founders Edition can demand close to 600 watts under heavy load (Source: HERE) and recent testing at KitGuru has highlighted that some third party partner cards currently under review can consume more than 620 watts. Therefore if you are pairing this up with an overclocked high end Intel or AMD processor I would personally aim a little higher – potentially at a quality 1200 watt to 1650 Watt power supply. Remember you do not want to be hitting close to 80% or more power demand on a sustained basis as it puts more strain on the capacitors and will cause the fan to operate at higher speeds which has the downside of creating more noise.

The PG-1000G passed our cross load test and ripple suppression was well within industry rated parameters. The 5V boost feature improved some of the minor rail readings a little, but I can't help but feel that ASROCK should have just enabled it out of the box – most people may not even see the little button, or understand what it does. Effectively it seems like somewhat of a gimmick to me – and just ‘another button to press for a cool new feature'. In the real world, whether the button was ‘off' or ‘on' , the unit performed perfectly fine so I don't think it deserves a lot of attention regardless.

Sadly I am unable to find the ASRock Phantom Gaming PG-1000G for sale anywhere as I publish this today and I have not been given any idea of UK or even European pricing. Making an assumption on pricing from my point of view is tricky, but I can assuredly say that if the price is right then this unit will be definitely worth buying.

Obviously if ASRock price the PG-1000G out of the market then it makes little sense considering it, but knowing the competitive nature of the brand generally I cannot see this happening. I really have a lot of power supplies to review and I can't hold this review any longer while I wait for pricing updates. If I get any updated information on this – I will update this page ASAP.

Pros:

• 105c rated capacitors.
• 10 year warranty.
• Great build quality.
• fully modular.
• primary rail ripple suppression.
• Cybenetics certifications in place.
• High quality cables.
• good PSU protections.
• quiet in operation.

Cons:

• ASRock can tend to suffer from availability issues.

Kitguru says: The ASRock Phantom Gaming PG-1000G may have one of the longest PSU names we can remember, but under the hood it is a very capable power supply that delivers great power for a myriad of high demand use cases.
