I've been surprised by how quiet the power supply is. It was easy to install - undo the screws on the old PSU, unclip all the cables (new ones are excellent quality), plug everything back in and off you go! In terms of performance, I've had this installed for 9 months now and it's not missed a beat. Very happy. Review: Well specced and works well slightly noisy - After having a Corsair fail after only a few months I did some research and found this one to be well specked and it works well so far! It is a bit noisy so I have converted the fan to 5v using a drop down converter for £5 and it’s quiet enough now. ## Features - 700W ATX Power Supply With 120mm Cooling Fan For Desktop PCs. - Single 8-pin (4+4 pin) 12v rail provides more stability and safer power output. - Power Factor Control (PFC).

If you use all the voltages at their optimum level then yes, it's 700 watts+. However, since about 570 output watts of that is allocated to the +12V supply and so If you are heavily loading the 3.3V or 5V supplies I'd expect it to struggle. **Q: Will this work for a amd rx 580 graphics card and does it come with cables such as the 230v power cable and an 8 pin pcie?** A: A qualified "yes" to the AMD card which recommends a 500watt power supply (and consumes 185watts). The qualification, of course, is what else you have in your system and there's not easy way apart from working out your expected total power needed. Cables, PCI-E 6+2 = 8 so yes it does - read the specification. As for the mains cable, to be honest, can't remeber, but it's a standard IEC. **Q: I'm buying this to replace my old psu as it got burnt. i need to buy new computer cable for this, so does it matter if i get 5a \ 250v or 10a 250v?** A: When you say computer cable, assume you mean the 3 pin mains cable to the power supply. In which case, no, it doesn't really matter. The 5 amp version would do for a 1200 watt power supply assuming it is from a reputable source. That said, I'd always go for the 10a version because they are usually physically stronger. **Q: My graphics card and motherboard both need a 6pin connector, will this power supply work ?** A: You'll need a 6-pin splitter cable (available on Amazon ...) but otherwise no reason why not. ## Customer Reviews ### ⭐⭐⭐⭐⭐ A good, economical replacement PSU *by E***V on 7 September 2025* Bought this to replace a 650W PSU that was struggling after I'd installed a more power hungry graphics card.

It is a bit noisy so I have converted the fan to 5v using a drop down converter for £5 and it’s quiet enough now. ### ⭐⭐⭐⭐ 4 star power supply *by M***S on 1 November 2020* Its a fairly decent power supply with a hefty output. As you can see in the photo its not modular and the leads aren't sheathed but it is good value for money. ## Frequently Bought Together - JUSTOP Black 700W PSU, Switching Power Supply, Computer Desktop PC ATX 120mm Fan 8-Pin 12V, 6+2 Pin PCI-E, 6x SATA (700W) - Corsair VENGEANCE LPX DDR4 RAM 16GB (2x8GB) 3200MHz CL16 Intel XMP 2.0 Computer Memory - Black (CMK16GX4M2B3200C16) - MSI PRO B760M-P DDR4 Motherboard, Micro-ATX - Supports Intel 12th & 13th Gen Core Processors, LGA 1700 - DDR4 Memory Boost 4800+MHz/OC, PCIe 4.0 x16 Slot, M.2 Gen4 Slots, various --- ## 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/174840133-justop-black-700w-psu-switching-power-supply-computer-desktop-pc](https://www.desertcart.sg/products/174840133-justop-black-700w-psu-switching-power-supply-computer-desktop-pc) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-05-15*
