Antec HCG1000 Pro Platinum 1000W PSU Review

Rating: 9.0.

It has been some time since we last looked at a power supply from Antec, however today we analyse a new unit from the company – the HCG1000 Pro Platinum. This is a fully modular, ATX 3.1 Platinum rated power supply currently on offer via Scan for less than £180 in the UK. Today we will find out if you should be shortlisting this power supply for a new system build.

When speaking with Antec they told us ‘The Antec HCG Pro PSUs are crafted to deliver unmatched performance, reliability, and efficiency. Available in various wattages, these PSUs are ideal for powering the latest gaming rigs and high-end PCs. With a focus on quality and innovation, the HCG Pro line stands as a beacon of our dedication to supporting your passion for gaming and technology.'

Marketing speak aside, when we asked Antec who the OEM for the PSU was initially, they told us that it was Seasonic. To get the latest technical data, I asked Seasonic directly about the new ATX 3.1 update and they said the following:

‘Regarding the new HCG PRO Platinum series (1200W/1000W/850W):

• The series is manufactured by Seasonic and is based on the latest version of the VERTEX PX, which is ATX 3.1 (as detailed on our website).
• We plan to roll out this new version from Seasonic in the coming weeks for our own VERTEX Series.
  • This is why our website has been updated
  • A note shown regarding 12VHPWR or 12V-2×6 cables – as both will coexist on the market while the latest version take over.
• Antec has already received this new version for their own PSU. It is similar to the VERTEX PX ATX 3.0, with the primary difference being the new 12V-2×6 connector/cable.'

Hopefully this helps to clear up any confusion people may have, as this is a very recent update (at time of writing).
