## Questions & Answers

**Q: Is this sfx psu ok for lian li 011d mini and a rtx 4080 ? or which one is best which comes with cables (ideally white). thanks**
A: The PSU should be powerful enough, and you may be able to get cable mod cables to complete that white PC aesthetic.

**Q: Can you use normal hard drives? What connectors do i need or dose this power supply come with them**
A: I'm assuming that by "normal hard drives" you mean a 3.5" HDD (the older spinning drives). If that's the case then yes, this PSU will be able to provide power to that drive and it'll come with the cables that you need.

**Q: How long is the 24pin ATX cable? I had to replace the one that came with the SF750 as it was too short.**
A: ATX 24 pin - 300mm
12V EPS - 400mm
12VHPWR - 400mm
PCI-E - 400mm (daisy chain +100mm)
SATA - 100mm 1st, with 3 daisy chains adding 115mm each
Molex - 100mm 1st, with 2 daisy chains adding 115mm each

## Customer Reviews

### ⭐⭐⭐⭐⭐ unbelievably superb!
*by T***R on 15 August 2024*

I have this PSU for around 3-4 months now. I can say it is the beast. The quality and the cable selection is good. The best part is, even in the tiny ITX case with, Ryzen 7700X, 96 GB ddr5, 3 x NVME Drives, 5 Sata SSD's and 1 Sata 2.5" 7K2 disk + Nvidia RTX 2080Ti, PSU fan is not even turning fir the all idle and most of the workloads. To be honest, I am not a gamer, but the system pulls around 110W idle and 370-400W during the high workload and 150-170w(Fan is not even making single spin AMAZING!) during standard working times. The efficiency is also good. Definitely suggesting.

### ⭐⭐⭐⭐⭐ A Compact & future proof little powerhouse.
*by J***N on 2 September 2024*

What can I say I love this little PSU, so much so I've brought an additional few more. But less about my purchasing habits & onwards to my review.This small-form-factor power supply packs a surprising punch. With its 1000W output and fully modular cables, it's perfect for high-performance builds in compact cases.The SF1000L's quiet operation and 80 PLUS Gold efficiency make it a great choice for anyone who values both performance and energy efficiency. Its zero RPM mode ensures near-silent operation under low loads.If you're looking for a reliable and powerful power supply for your compact PC, the Corsair SF1000L is definitely worth considering.
