The Lian Li SX1000P is quite an impressive power supply, while the choice of white and black models will also appeal to a wide audience. Finishing quality on the external unit is very high and I especially like the various height angles of the top mesh panel. I don't think I have ever seen that before. It is subtle but effective.

Lian Li are working with OEM Zhong Yuan Power for this unit and likely the 850W and 1000W in this range as well. While this is not a company we see very often, they are more of a background operation, rather than a front facing manufacturer like Seasonic or CWT. They are a Chinese outfit that have built their own units for brands such as Darkflash in the past.

Technically the unit performed well. Load regulation was very tight and it handled the cross load test without a problem. The adoption of high-grade Nippon Chemi Con and Rubycon capacitors in the primary and secondary stages helps reassure that it is a serious design. The primary 105C-rated Nippon Chemi Con capacitor is powerful @ 420V 1010uF.

I appreciate that they opted to include a high-grade Hong Hua fluid dynamic bearing fan in the unit, these are good fans we have seen in products from other leading brands such as Seasonic and DeepCool. Under most load situations it remains inaudible, or almost inaudible, and only at close to full load will you hear it operating.

I was a little surprised that this unit didn't ship with Cybenetics certifications on the box, and when I enquired with Lian Li about this, they said they were currently working with them to get certifications. The unit currently has 80 Plus Platinum certification, and we hope Lian Li will update their data if and when Cybenetics give them approvals.

The price of this unit is very competitive, considering this is a 1200W Platinum rated PSU. At the MSRP of $159.99 it delivers great value for money. The 850W and 1000W versions will be priced at $119.99 and $149.99, respectively. We currently don't have any links or pricing yet for Europe or the UK, but we could imagine this product will cost around £150 in the UK and a similar amount in euros.

All in all, Lian Li have delivered a quiet, high wattage 1200W power supply that uses premium Japanese capacitors and delivers stable power at Platinum levels of efficiency. It is fully modular, well put together and is competitively priced with a 10-year warranty. It goes without question it should be on your final shortlist for a new system build.

Pros:

• Fully modular.
• PCIe 5.1 and ATX 3.1 compliance.
• Platinum levels of efficiency.
• White and black colours available.
• 105C-rated Japanese capacitors from Nippon Chemi Con and Rubycon.
• Quiet fluid dynamic bearing Fan.
• Ripple suppression is good.
• Load regulation is tight.

Cons:

• A lot of competition in this sector.
• Availability will likely be a problem in various countries (for a while at least).

KitGuru says: The Lian Li SX1200P delivers high-grade power at Platinum levels of efficiency. It is fully modular, quiet and the quality of the modular cabling is super. With a 10-year warranty, we rate this product very highly.
