As I wrote: «http://www.amazon.co.uk/dp/B00J01K3E8 is more probably that not the most affordable option».
If you want a PSU which is not noisier than your current CP850, those are the candidates I'm aware of.
doveman wrote:The closest in price is the Corsair RM750. If the RM series are good, maybe the 650W would be an option? It's not much cheaper than the RM750 or the EVGA though, so probably better to spend an extra few quid to have 750W rather than 650W http://skinflint.co.uk/corsair-rm-serie ... 00826.html Which would you say is the better choice out of the SuperNOVA 750W and the RM750?
The eVGA is a FAR BETTER unit than any Corsair RM: the first is in the same league of Seasonic Platinum/X-series, the second is more similar to Seasonic G-series. The Corsair RM650 is inferior to both (it's a different platform than its larger brothers).
On the other hand, given that they all are hybrid (semi-fanless) units, noise-wise they are comparable.

As I already pointed out to you several posts ago, the L8 is a low-end unit with an enough-low-speed fan (Silent Wings Pure, with a rifle bearing) which is not comparable to the SuperNOVA G2-series.
You may read something about the SuperNOVA G2 in several reviews on Anandtech, TechPowerUp!, JonnyGuru, HardOCP and many others.

Are you kidding, or do you really want to compare an about-1-year-old-10-years-warranty-semi-fanless-80+gold-platform @ £82 (& Amazon Customer Service), with an about-4-years-old-3-years-warranty-fully-fanned-80+bronze-unit @ £76 (& Lambda-Tek Customer Support)?
The 630W model is pretty cheap so it offers a better value than the 730W unit, but it does not offer a better value than the SuperNOVA G2.
Whether you'll draw >300W (and probably less than 450-500W), I don't think the L8 can run as quiet as the hybrid (semi-fanless) EVGA, while if the power draw were around 230W (gaming figure, like a Core i5 + GTX 760-class card) YMMV (it depens of enclosure, placement and so on: but it would still be a clearly inferior PSU, performance-wise).
Check the above mentioned reviews (AFAIK at least JonnyGuru usually measures cables length).doveman wrote:One nice thing about this CX750M I'm using as a temporary measure is that the SATA cable is very long with the headers spaced far about, so I might be able to just use one to power both HDDs and the X-Docks (which only use one power connector for both), keeping cable clutter down, so if any of the SuperNOVA or the L8's have the same, that would be useful to know when choosing between them.
