Great for my first time gaming build R9 390
One of my friends help me chose this modular power supply and I must say it's really useful, especially for me being my first build. You can use only the wires that you need and it's excellent for cable management from this point of view. It's really intuitive and looks really well made and sturdy. Even though it was shipped with an EU power lead rather than an UK one, still giving it 5 stars. But amazon support was really prompt and got back to me on a Sunday (!) with a resolution. I definitely recommend this for first time builders as myself and you can't go wrong with this and it gives 5 years solid warranty hence your expensive parts are insured.

Built like a tank, 520w powering my AMD Vega
That's right, you don't need a 600-700w PSU for a Vega, a rock solid quality PSU of this calibre with 520w will power Vega 100% with no risks, just undervolt your Vega 56 as it nets you an insane 9%-14% FPS increase in 4k and thus make it basically equal to a stock non overclocked 1080! Imagine that, that's literally a whole GPU tier. Been using this PSU and my Vega for around a year and powers my Vega at full power and wattage for hours no problem. Bought it for 50 quid at the time so was a steal.

Great for my R9 390 gaming build.
Very good psu, it is my first full modular psu, but for the price it could be somewhat cheaper as this is classed as a type 2 psu (on tomshardware forum site) according to the quality. The reason i took out a star is because for its price, the cables shouldnt be so difficult to remove from the psu, especially the motherboard cable. Once you connect the cable to the psu end, you have to really jerk it out of the psu if you plan on taking it out again. Otherwise the psu is very good quality, comes with loads of cables, and is ample for my pc.

Perfect
This is the first time i've bought a modular power supply as i haven't built a PC in quite some time. Seems very quiet and stable and to be able to only use the cables for what you need and not have any excess wiring it really helps with cable management/cooling. Well worth the buy.

Quiet and functions as advertised
Previous customer of Seasonic PSU in another system build running 4yrs+. Did not disappoint in buying another Seasonic PSU. Happy with first time purchase of modular design, although motherboard connector cable is stiff and difficult to manage for aesthetics.

A trustworthy brand for arguably your PC's most critical part.
Seasonic is basically the only brand you can absolutely trust for PSU's unless you spend ungodly amounts on 1000W Gold Rank power supplies. Their electronics are just quality. There's not much to say about PSU's in a review. It gives your PC power. But of course, that's a critical job, and its one area you never skimp on. A budget one erupting in flame and fusing your entire motherboard is not a good idea.

Amazing power supply
Very reliable power supply. Incredible modularity for the price and comes with a wide range of different cables. The manual is very helpful when it comes to wiring in everything. Would recommend.

This part was delivered well and put into son’s new PC and works well over the past 3 months hence deserves a 5 star for now. Hope it lasts too.
