This is the first SFX platform from Helly Technology I have seen, and I am impressed. With some changes, this platform has the potential to face off against Great Wall's excellent SFX design used by the Corsair SF Platinum and Gold models. For starters, I would suggest providing inrush current protection, which won't affect performance, but will increase production cost, and tune the EMI filter to lower EMI emissions. The hold-up time should be close to or above 17 ms, but there is no space to install bulk capacitors large enough in such small units with increased power output, so users should be willing to compromise in this regard. Even Corsair's top SF750 Platinum cannot exceed 12 ms hold-up time.

The brushed aluminium housing and individually sleeved cables make for a visually nice exterior. Speaking of the modular cables, I would like to see dedicated cables for the EPS connectors since they can draw lots of power, and this PSU can deliver 1062 W of power before OPP shuts it down. There are four 8-pin sockets for EPS and PCIe cables, so I don't understand why Lian Li chose to only utilize three and doesn't provide dedicated cables for the EPS connectors. The odd PCIe connector count might look weird, but with the maximum number of PCIe connectors for today's graphics cards being three, this cable configuration makes sense. The SP750 can even support an RTX 3090 as long as you don't use an HEDT CPU with as much peak power consumption as the GPU.

At $140 in the US and a price close to €130 in the EU, the Lian Li SP750 is a very good choice. With some changes that wouldn't affect its price tag dramatically, this platform would offer increased usability and higher performance, forcing Great Wall to update its excellent SFX platform which has for quite some time now been the performance king in my charts. I expect to see more by Helly Technology, and kudos to Lian Li for cooperating with this capable OEM.
