Review: Amazing SFX-L PSU. - I was wary of buying this after many complaints about noise for the V1.0 but it seems like they've done away with the hybrid mode and just have the fan constantly on but it spins at such a low RPM you cannot hear it over anything else. I'm all about low noise computing and this is definitely the most silent in my system (well apart from my SSDs). I have an i7-4790K paired up with a GTX970 and they draw a little over 250W from the wall at max load and this PSU never breaks a sweat and doesn't feel hot and never spins up, even in my lovely looking but poorly ventilated Jonsbo UM3X case.
Review: Easy install and as 'silent' as you would reasonably need - Office pc had a very noisy psu fan so thought I'd give this a shot looking for as close to silence as possible on a budget. Straight forward fitting, came with a plate which my case needed as the old psu was larger (as well as whooshing like a hoover). Switched on and I have to admit that I initially thought it wasn't powering as there was no sound at all but pc booted and works perfectly. The thing is genuinely silent - at least within reasonable parameters. Highly recommended for modestly spec'd pc's.

## Questions & Answers

**Q: Will this fit into a hp elite 8300 sff case?**
A: You'd have to check the dimensions and measure the space in the hp.  It's likely not to follow standard sizing.

**Q: May i ask to comment on the amount of noise under high cpu load?**
A: Its depepends on what CPU you are using as well as total system load. I have a i5 4590 and it becomes audible under load.

**Q: Will this fit into the silverstone sst-rvz03b - raven?**
A: It should be fine. Mine was a mini itx build and that fit perfectly. My rig is small enough to fit in a medium size rucksack. Hope this helps.

**Q: Would this fit a hp s5653uk? and motherboard ms-7613?**
A: depends on the age of the other equiptment, modern power supply outputs have to cope with more stringent standards imposed by the lower voltage demands of modern CPU which need less fluctuation of that voltage than order CPUs could cope with. The different specification require by moder CPUs mean that modern power supplys are nolonger backwards compatible.

### ⭐⭐⭐⭐⭐ Amazing SFX-L PSU.
*by U***I on 5 October 2016*

I was wary of buying this after many complaints about noise for the V1.0 but it seems like they've done away with the hybrid mode and just have the fan constantly on but it spins at such a low RPM you cannot hear it over anything else. I'm all about low noise computing and this is definitely the most silent in my system (well apart from my SSDs).

### ⭐⭐⭐⭐ Solid and powerhouse of a SFX PSU
*by P***B on 11 February 2018*

Picked up the SST-SX700LPT to go into a mini-ITX build and thus far doing the job perfectly fine. With 700w the unit is capable of feeding most CPU and GPU combinations around and for most the at much less then its rated capacity for typical parts so works fine in that regards. This unit is of course the slightly longer SFX-L and the extra housing is used to accommodate a larger 120mm fan. For most the part under low loads the fan does not spin at all (provided it also has adequate airflow) and only when it gets hotter under a load such as gaming, will the fan spin up, though to be honest even then, its fairly inaudible to me. There are plenty of cables included of the flat ribbon variety and thankfully this time unlike my last purchase of a SFX silverstone PSU, they actually include a UK model kettle lead. Oddly unlike with the 500w SFX-L unit from Silverstone also, they have not included a SFX to ATX power bracket, so you will need to buy one if you plan to eventually put into a ATX case, something that would make more sense with a 700w supply over a 500w supply to be honest. Anyways, it does what it says on the tin. If I did not have the custom sleeved cabled, I think I may have looked at the 600w corsair SFX unit to be honest, as its much cheaper yet looking at online review's (JonnyGuru) and the like performs even better in area's like ripple and 600w is adequate for most builds.
