Unboxing was fine - everything nicely packaged, and all looked good. But plugging in and getting it charged up (before hooking it up to anything) was a bit of a surprise: the small fan runs it quite a speed and is very, VERY noisy. It's like an old-school CPU fan running at full tilt - it sounds like it wants to take off. It's not noisy like the fan bearings have failed - it's just "fan noise": as I sit here writing this I'm in a different room with a corridor between me and the study (with my door and study door open), and I can hear the UPS from here. If I closed both doors, then I'm sure all would be well - but I'm not sure how easy it would be to actually work in the study with the UPS sitting on the desktop. I can't imagine having this in the lounge - the fan noise would be a major distraction while watching TV or a film. Maybe mine has a faulty fan??I'll update the review at a later stage - the UPS needs to charge for at least 4 hours according to the instructions (or 8 hours, according to the website) after which I'll hook it up to my QNAP NAS. Maybe after charging the fan speed will drop and it'll quieten down... Or maybe once I've hooked it up to the software I can configure the fan to calm down a bit. We'll see.EDIT 08/04Increased to 4 stars. The fan is still very noisy, but it seems to be only when the internal battery is charging. When plugging in for the first time, the fan ran for hours into the night; the fan was silent the next morning and I thought everything was fine... When I plugged my NAS in and switched on the UPS< the fan kicked in again - and it ran for quite some time (leading me to worry that it would run whenever the UPS was actually on). It's quite again now, so I guess it only runs when the battery is being topped up. There's no mention of this in the documentation, however - I went as far as trying to log a support call with Salicru to ask about the fan.Another poing worth noting: if/when you register with Salicru, there's more than one type of "SOHO+". If buying the one I bought (2000VA) then you need to choose the 2nd one listed in the drop-down. It's listed as "SOHO+ (black front)" or similar.. Only then will you be able to find the correct documentation.So - dropped a star for documentation making no mention of the fan operation (and for it being a bit of a faff to actually find the documentation!) Also it's a minor annoyance that the 'feet' of the UPS aren't rubber, so it slides around like crazy on my desktop (I'll have to get a rubber mat to stand it on). Other than that, it seems to do the trick. ### ⭐⭐⭐ Check the age.... *by N***E on Reviewed in the United Kingdom on 19 May 2020* Ordered one of the 1000VA/600W for the home study, and running an HP z600 workstation and 42-inch screen etc. I charged it for 2 days and then tested it. Battery dropped straight to just over 50%, but lasted about 20 minutes before sharply dropping again and I reconnected the mains. Checked the review by Andy, and assuming the serial numbering is the same format, figured this was a 2018 build, so as expected from the test the batteries are a bit 'old'. I logged a support call, and had nothing back in two weeks. ### ⭐⭐⭐⭐⭐ Reasonable budget UPS *by A***M on Reviewed in the United Kingdom on 8 September 2020* I've had the SPS ONE 700 version of this for about two years now, connected to a mid-range desktop PC and 21 inch LCD monitor.It's very compact and has dealt with several power cuts over that period. My machine will run for at least five minutes on the UPS, more than enough time to save everything and shut down.Since UPS batteries have a habit of failing after a couple of years, I recently decided to replace it. If you have a minimal level of technical know-how, this is very simple. The only tools you'll need are a cross-head screwdriver to remove the four screws attaching the top portion of the case to the bottom and a knife or thin-edged flat-blade screwdriver to ease open the clips attaching the front fascia to the main body on the underside. Once you have the thing apart, disconnect the two spade connectors on the old battery and remove it, put the new one in, reconnect the two connectors (paying attention to polarity, of course) and reassemble. The battery in the box was a brand I didn't recognise, so I decided to replace it with a Yuasa NP7-12 AGM S65 12V 7.0Ah (currently available on Amazon for a price that's about a quarter of this UPS) which is the same voltage and current spec as the original, and it fit perfectly.The only downside of this product is the awful monitoring software. Every time it starts, Windows 10 asks for admin permission to run it, and I couldn't figure out a way around this. In the end, I removed it from the list of start-up programmes and ran it manually occasionally to check the state of the battery. The only disadvantage of this is that the software couldn't be used to automatically shut down the PC in a power cut, but Windows 10 copes with improper shutdowns well. Everyone with any sense should have the habit of saving their open work before walking away from their machine, and the UPS software wouldn't deal with this in any case. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/65226353-salicru-sps-one-500-series-line-interactive-uninterruptible-power-supply](https://www.desertcart.sg/products/65226353-salicru-sps-one-500-series-line-interactive-uninterruptible-power-supply) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-09-25*
