Like most any other product anywhere, manufacturers build products for various price niches ... forget about brands and base your decision on the product's model / series number and what platform it's on. Most PSUs are OEM'd and the same PSU with minor differences mat be sold under numerous brand names. While the Seasonic Focus Gold + is our 'go to" model series here in the US, availability and affordability are limited in other countries. Seasonic and Superflower focus primarily on the upper market tiers ...tho some of their lines might be considered low to mid range, don't see those too much in US, can't speak to UK. EVGA aslo makes some great products, but hey also cater to the the budget conscious.
Won't argue about you preference for full modular. but itn must be recognized that, unless you are resleeving your cables, modular has 0 advantages and some disadvantages over semi modular.
1) Every build will require that certain cables MUST be connected. The advantage of modular is that you don't have to connect unnecessary cables, but there is no advantage using modular for cables that must be connected system can not be turned on. Two identical PSUs in modular and semi-modular format will have a proce difference favoring the modular. So you are paying extra for something that returns np value other than pyschological.
2) Each modular cable introduces a potential failure point ... faulty pin / connector point, loose cable.
3) Slight increase in resistance / slight loss of efficiency.
4) There's a reason trouble shooting staps incluse disconnecting all cable, remocing all components from slots ... cleaning the contact points and cleaning them
So yes, if it's something you just "like", go ahead and pay the extra money. But there's is 0 upside here so if budget is important worth considering.
has included elevated procing and further back, limited availability. This has improved significantly of late.
At £89.99, the Seasonic and SF are a step above the G1
The Focus Gold Plus series has been very well reviewed:
Seasonic FOCUS Plus 850 Gold Power Supply - Performance 10 / Build Quality 10 (9.8 Overall ... lost points for cable capacitors)
Seasonic FOCUS Plus 750 Gold 750W - Performance 10 / Build Quality 9 (9.6 Overall ... lost points for some sloppy soldering .. perhaps a "one of" thing)
Seasonic FOCUS Plus 550 Gold - Performance 10 / Build Quality 10 (9.8 Overall ... lost points for cable capacitors and documentation)
The 650 watt unit was reviewd by PC perspective and here's the link
Seasonic FOCUS PLUS Gold (FX) 650W PSU Review Introduction

Leadex III has a 7 year warranty / Seasonic has 10
The Super Flower Leadex III with 650 W performs very well in all areas: load regulation, ripple suppression, efficiency, and transient response. On top of that, it is one of the quietest PSUs money can buy today and has two EPS connectors for power hungry CPUs and mainboards.
