SeasonicFOCUS PX-750 Fully modular PC power supply 80PLUS Platinum 750 Watt

I bought this (Seasonic PX-750) as an upgrade for my system in preparation for upcoming GPU releases to replace a Be Quiet 500W unit that I have been very happy with. My whole build is silence-focused, so it's important to me that the PSU also be silent or near silent.I inititially picked up a Corsair HX750 for this upgrade but I will be returning it since the coil whine is awful, even under light loads. Under heavy power draw it was obnoxious. I decided to try Seasonic based on brand reputation as an alternaitve and I should have just bought this thing in the first place. It is a superior product in all categories!Pros:* Physically compact fully modular unit. The footprint of the PSU itself is roughly square and quite small. It's similar to the 500W unit I replaced and it is noticably smaller than the HX750 (especially in my mATX case).* Bundled cables are quality but very pliable, making installing them a breeze. The connectors are also high quality and are easy to plug and unplug at both ends for cable management etc.* Zero RPM fan mode. It has a fan (and a switch to disable the fanless mode if you want), but I have yet to hear it. Fanless under low load, and inaudible over other system fans at high load.* ABSOLUTELY ZERO COIL WHINE ON MY UNIT. Your mileage may vary, but even under very high CPU and GPU load my unit has absolutely no coil whine at all (that I can detect).* I bought mine from amazon UK and it shipped with a UK plug in the box.* 80+ Platinum is nice to have for efficiency.Cons:* The PCI cables for the GPU are double-headed (as many are) and the way the connectors are fitted means the "tail" connector is hard to hide if you don't need to use it. This is a minor quibble. The cables themselves are flexible and easy to route and long, simplifying the rest of the cable management.* The ATX cable, while it is well designed (and one of the best/most pliant I have used) doesn't have a great deal of extra slack. It fits just fine in my MicroATX build, but it might be a tricky fit if you have a massive case. It's a compromise due to the thickness of that cable (too much sack in it makes cable management impossible), but it is something to think about if you are going for E-ATX or something like that.Overall I can highly reccommend this PSU. It's compact, silent, has great cables and most importantly to me, has no discerable coil whine at all.

CAUTION - pictures show x5 CPU/PCIE cable connection points on the PSU. Only the 850w & 1000w PSUs have x5.550w / 650w /750w have x4. May not be an issue for all, but if you need x5, amazon pictures are misleading.No specs on amazon page so please see manufacturer's site for details.No other factors considered in rating.
