Lian Li SP850 850W Power Supply

The power supply is cosmetically nice and the cables are nice as well. The deal breaker is the sound it is producing. We returned our original purchase as we thought the volume and vibrations coming out of the unit was a fault. The second one has made exactly the same noise. It may be silent at 40% load, but that dosen't last long and it sounds terrible above that. PB Tech were faultless in this one star rating, in fact they swapped the first one without a fuss. However I promise you it is so bad you will not want to buy it. Reviews can be found highlighting the same fault on other sites. Shame should be a nice item.

It's really small and quite and was perfect for my itx build. It's really small and quite and was perfect for my itx build.

Runs wonderfully and quiet in my sff build. Runs wonderfully and quiet in my sff build.

Was surprised to see how small SFX actually this. Fit into the o11 mini with no worries - and it is very quiet. Was surprised to see how small SFX actually this. Fit into the o11 mini with no worries - and it is very quiet.

Runs my High-end build with no performance problems, but the fan is a little loud for my liking. Runs my High-end build with no performance problems, but the fan is a little loud for my liking.

I got this to power my upgraded rig (added an rtx 2080ti and ryzen 5800x). It handles the load fine, and the cables it came with are really nice.

Installing it in my itx case was a little tricky as the ports are close to the bottom of the case. But i managed to get everything in.

I wish there was a way to disable the 'silent below 40% load' feature. In practice, with a low load (just using a web browser etc) the fan starts up randomly for a few seconds, sounding extremely loud, before switching off again. And under heavy load (like a demanding game), the fan might switch off during load screens or when paused.

This fan switching is far more irritating than the sound level itself. (Which is also very loud.)

Clean white tables great psu for the price running a 3070 with 3700x cpu and runs quiet not over the top fan noise Clean white tables great psu for the price running a 3070 with 3700x cpu and runs quiet not over the top fan noise

I bought this Power supply to swap out the 650 in the NZXT H1 Case fits like a glove and was one of the only PSUs i could find with a 2x PCIE splitter for my 3090 as it needed 3 8 Pin it does get a little loud under load but its unnoticeable when gaming or watching videos Amazing buy for the Price.

Love the full modular, lets you do a real tidy job of the cable management - Fits Perfect in a O11 Mini - Good enough power for a 3060TI and 9 fans, AIO etc. No Spikes or fluctuations. And As Always PB Tech -Bang on with freight and service.

Price point is good for a high watt SFX model, really small unit. Can hear the fan whine during heavy loads but its not that bad, to be expected from a small fan. Silent during idle. I did need to buy an extension cable for the 24pin ATX as I'm still using a mid tower case - it would be fine in an SFF case Price point is good for a high watt SFX model, really small unit.

This unit is well built, small, and it does what it should. It fits nicely in tight spots as it is very (obviously) small. Don't expect too much of it though as it's meant for small builds including one "normal" sized gpu. It is currently powering an x79 build with a 12 core xeon and a 780ti in a huge server case (tight area for psu in this case). This unit is well built, small, and it does what it should.
