Antec High Current Pro 'Platinum' 750W

Hi everyone, I'm new here, so please try to forgive any ignorance,



At the start of the week, I thought that between reading a multitude of reviews, I had narrowed down my choice for a new PSU to the Corsair AX760i and SeaSonic SS-760XP2. Alas, after posting on the Linus Tech Tips forums, I was introduced to the Antec High Current Pro 'Platinum' series and now I'm all confused again :wall:...



For some context, I've decided that it's time to upgrade my old Corsair HX650, since I'm also in the market for a GTX780Ti K|NGP|N and it's one PCIe pin-out short. Furthermore, I've just added a RAID 5 array and LSI RAID card to my PC, and I wouldn't mind another 100 Watts of headroom.



Since I'm in the market for a 750 - 760 Watt PSU, price isn't an issue and I'll happily pay £200 if there's some super premium option I've missed, but which has a significant quality advantage. However, it seems that for this power output, prices stop at about £150.



All of the above feature on the Tom's Hardware list of 'Tier 1' PSUs, although quite how objective that list is, I'm not sure. They all feature reassuring 7 year warranties too. Regarding power delivery, different sources say different things and there are no comprehensive reviews of the SeaSonic unit (although the 660W unit has been reviewed here, I'm not sure quite how similar it is in construction to the 760W unit). The impression I've got however, from the reviews of the Corsair and Antec unit's 860W big brothers on this site though suggest that the Antec delivers entirely perfect power on the minor rails whilst the Corsair is slightly better on the 12V rail(s - in the case of the Antec). Similarly, the Corsair has slightly better ripple characteristics.



Nevertheless, I'm leaning towards this Antec unit because it would seem that it is by far the best built, what with Delta being the OEM. I know nothing about electrical engineering and my only experience of capacitors is wiring them backwards and blowing them up in A-level Physics, but even to my eye, the quality of the unit as a whole was evidently much higher. Furthermore, JonnyGuru's use of Delta as a hallmark of quality, would seem to indicate that their manufacturing and design is in all ways more sophisticated.



"Seasonic is still not the best in the world when it comes to build quality. Delta is. Impervio is."



"Excellent soldering, here. Not quite as good as I've seen from the likes of Delta, but good enough that I don't feel the need to pull points for it."



"Flextronics is our OEM for this one, which is no shock to me. It takes a server grade OEM to give us Delta like performance, especially at this power level"



"Delta build quality. Enough said."



My question therefore is, which would you recommend/have I missed another, superior unit?



The other question I have concerns the price of the Antec units. The 750W is a very reasonable £129 on overclockers.co.uk, whilst the 850W is £175. This seems a disproportionate price difference for the difference in power output, and since only one of the two has been reviewed here, I'd just like to confirm that both are built to the same standard.



Thanks very much for you help,



Kind regards,



Charlie
