    Hi there


    As people have requested it here is a guide on what PSU's should help to reduce mild/low coilwhine issues.

    Key Points
    • Sometimes even the best PSU on the market will not eliminate coilwhine
    • Coilwhine is not a fault, it is how electricial devices work and any card can suffer it, particular high-end cards, such as dual GPU solutions
    • OcUK stance on coilwhine is if you have a quality PSU and the card has audible coilwhine on an open test bench, we will replace it.
    • Does 970 suffer from whine more so than other cards, well return rates cannot be conclusive of this as we are seeing nothing unusual in return rates but the majority of returns are related to whine issues.
    • Whether a PSU is 80+ Gold does not necessarily mean its a good quality PSU, it is down to the internal components used and frequencies etc.














    No money no object, best quality PSU's ideal for Tri/Quad SLI that I/8 pack recommend

    Summary on premium Power Supplies


    In short myself and 8 Pack have our favourites when it comes to having the highest quality PSU, we both are very happy with the Superflower Leadex models, EVGA P series are also exceptional as they too are built by Superflower. Another firm favourite is the Antec HCP 1300W Platinum and of course the Corsair 1500i is a great unit but the price is very high and in short the EVGA 1600W Superflower units are superior. When it comes to these power supplies Superflower and EVGA are giving the best quality but also at a lower price point than competing brands.

    Summary

    In this area if you want quality and at a good value for money price both EVGA and Superflower are kings here, the engineering quality is undeniable and they are fairly priced. Also again Antec quality is unquestionable. Also anything that is built by Seasonic should also be fine, XFX for example.















    Lower cost PSU that are still built using quality internals


    This is a list of PSU's suitable for those who are building a gaming PC but cannot quite afford a quality PSU, this is where it becomes quite a mindfield as there are so many 80+ rated PSU's but the ratings are not a guarantee of quality components.

    For example here is an 80+ Gold certified PSU I'd not touch with a barge pole, its built to a price point and as such we do not recommend it and it would whine like crazy potentially as well.

    Summary


    Please bear in mind this is a personal recommendation by myself and what me and 8 Pack would use in our own home systems, recommend to friends or use on our overclocking attempts. We might work for OcUK but when it comes to power supplies we get very personal as we've come across so many units that have all the labels, certifications and marketings to make them sound good, OcUK even sells many such PSU's but we'd not touch them. Above are our recommendations on getting the best build quality for your money and without a doubt both Superflower and Antec are our favourites. For those who are concerned how Superflower only goes upto 1300W, well in the new year we shall have models going upto 2000W and Titanium specification.

    So the above is what we would use personally and our first port of call is always Superflower, they have simply out shown all other brands when it comes to using the highest quality components and this shows in reviews that do ripple test, Superflower are normally always King for lowest ripple results, this is why some users have reported Superflower units reducing or eliminating coil whine for them. But bear in mind some cards are beyond help no matter what PSU you use.

    When it comes to power supplies, remember if your building a high-end gaming PC that is like a sports car engine and anyone here old enough and lucky enough will know highly strung engines only run to their full potential and optimal ability when fuelled on premium fuels such as Shell Vpower/Nitro for example, run a high performance car on supermarket fuel and they can run terrible.

    A high performance PC is no different, the power source needs to be of very high quality to ensure not only stable running but to try and keep noise levels to a minimum, especially electrical noise.

    Of course the PSU cannot cure cards with coilwhine beyond help, but in short if your buying Superflower OEM built power supplies or Antec and then going with say a graphics card that is built around reducing coilwhine you will be very unlucky if you experience any whine.

    So if your building a gaming PC then please do not try to save money on buying a PSU with cheap internals, it is simply not a good idea and our recommendations are as per above.







    In short anything Superflower HX and Leadex are very high-end internally. Antec are also a good shout and also Seasonic OEM built units as well. I personally will not recommend anything else, though we do sell many other models so you are free to chose but you asked for my recommendation and well you have it. :)

    Much appreciated Gibbo. I am going to pull the trigger today on getting a new PSU as my coil whine is pretty unpleasant... just to confirm, if I get one of the recommended PSUs and it whines, then its okay to send to RMA?

    I'm looking at the sub £70 models...

    Hi there


    OcUK has taken moves to try and completely eliminate any kind of coilwhine by designing cards which incorporate coil whine reduction technologies on the 970 series.

    Here are both those cards designed by myself and exclusively available from OcUK and www.caseking.de


    OcUK GeForce GTX 970 "NVIDIA 970 Cooler Edition" 4096MB GDDR5 PCI-Express Graphics Card **WorldWide Exclusive** @ £319.99 inc VAT

    [​IMG]

    nonl2br

    This very special NVIDIA GeForce GTX 970 is the only one of its kind designed by our in-house VGA Guru Gibbo making this the worlds ONLY genuine reference 970 available in the world. Gibbo's design request were very specific, genuine NVIDIA 970 cooler, yes the crazy expensive one just like the 980 cooler and a NVIDIA BGA Board using all original NVIDIA components with absolute zero cost down in the design.
    <br>
    <br>
    Infact Gibbo improved the design by changing the containers in which the inductors are located for better quality items to help reduce and eliminate any possibility of coil whine. We also instruct our factory to only build these cards with Samsung memory. So why buy this over any other 970, well it is most likely the quietest whilst under load (gaming) due to having the NVIDIA cooler and any chances of coil whine have being pretty much eliminated with the design changes Gibbo has had implemented.
    <br>
    <br>
    So this card is ideal for those seeking as little noise as possible and the other major advantage is the NVIDIA cooler which offers much better cooling performance in smaller enclosures or when running in 2-way or 3-way SLI.
    <br>
    <br>
    Finally of course this card is perfect for when Half Life 3 is finally released at some point in the future and of course the latest GTA V game which is now confirmed!
    <br>
    <br>
    The GTX 980 is the worlds fastest GPU and the GTX 970 offers the most advanced performance in its class. Each delivers 2x the performance of previous-generation card, bringing new gaming experiences to virtual reality, and ultra resolution 4k displays.<br /><br />

    Enable the detail of 4k monitors, on a 1080P display. DSR produces smoother images by rendering a game at a high resolution, then downscaling it to the native resolution of the display using advanced filtering.<br /><br />

    GeForce GTX 980 and 970 cards support tear-free, super-fast NVIDIA G-Sync monitor display technology including 4k. Together, these technologies provide the most immersive and competitive gaming experiences possible.<br /><br />

    GALAX GeForce GTX 970 OC Silent "Infinity Black Edition" 4096MB GDDR5 PCI-Express Graphics Card **WorldWide Exclusive** @ £299.99 inc VAT

    [​IMG]

    Since Overclockers UK introduced our Infinity system range, demand for high performance zero compromise systems has exploded. Our Infinity brand represents performance hardware coupled with a unique and stylish aesthetic.

    Since the release of high end Maxwell architecture, the hardware game has changed. The new GeForce cards offer revolutionary new technologies and class leading performance alongside low operating temperatures and impressive power consumption.

    The GALAX GeForce GTX 970 OC Silent "Infinity Black Edition" is a collaboration of one of the largest Nvidia board partners worldwide, Overclockers UK Graphics Specialist: Andrew Gibson and Overclockers UK Technical Specialist & Overclocking World Champion, Ian ‘8Pack’ Parry.

    Originally the Galax 970 EX OC Black Edition was intended as a high performance option for customers looking for the ultimate gaming experience with class leading performance. Our close partnership with Galax allowed us to specify a list of important modifications that would make the GALAX GeForce GTX 970 OC Silent "Infinity Black Edition" a real show stopper.

    Primarily, to fit the Infinity aesthetic, we demanded that the external design of our Black Edition card was sleek and stealthy. Adding to the already imposing look of the Galax design, this new, aggressive appearance really highlights the intent behind this product.

    Additionally to the colour change, we included a nickel plated I/O plate, heatsink and heatpipes to compliment the premium nature of the product. The already impressive backplate on the card has been accented with a stylish "Infinity: Inspired by 8 Pack" decal.
    The imposing looks of the card would be nothing without the ‘go’ to back up all the show.

    Building on the already impressive performance of the GTX 970 platform, world class overclocking expertise from 8Pack has been implemented to fine tune the BIOS of this card to achieve maximum safe, reliable performance from the GTX 970.

    As an industry leading gaming and high end hardware specialist, Overclockers UK understands the importance of offering a product that meets a customer’s expectation. A major worry for any enthusiast is operational noise under load. We have used this knowledge to reduce coil whine by using higher quality components and also using glue to attach the inductors to the PCB to help reduce electrical vibrations which help reduce whine.

    This collaboration with Galax has allowed us to build what we believe to be the finest example of a GTX 970 on the market today.

    This product is exclusively available from Overclockers UK and Caseking group throughout UK and Europe. We suggest European customers visit www.caseking.de to purchase this card in Western Europe and Eastern European customers purchase from http://www.kellytech.hu/

    The first card is built using no cost down methods whatsoever and is why it is built on a 980 PCB which is way beyond what a 970 required and we had the inductors placed in higher quality containers to keep any noise to a minimum and then had insulating pads between the inductors and genuine NVIDIA cooler.

    The second card was built again using highest possible quality inductors and containers, but we then also had them attached to the PCB using glue which can be very clearly seen as the glue used is red.

    These steps help to reduce and eliminate coilwhine completely! :)

    Yes, the PSU will not always cure it but me and 8 Pack have used and tested so many and the ones above are what we both recommend, we personally would not buy or recommend anything else.

    Of course OcUK as a store sells many other models and brands, they are just simply brands neither myself or 8 Pack would use in our own PC, so take that as you see fit. :)

    Couple of reviewers have been discussing with me about the EVGA G2 series almost surpassing the Sea Sonic Gold units in tests and performance as wel as general build quality. Definitely a new contender. The digital Corsair series are also one of the few 1KW+ PSU's to get immensely high scores, on par with the Sea Sonic units.

    I'll also reiterate after doing tests on the CiT gear, they're one of the most dangerous PSU's available on the market. Managed to get one to go pop after 12 minutes of a stress test.

    This, long long time ago used to have a 600w cit. it literally blew up (nothing died though), this is from a single 560ti and a phenom 955.

    Well 8 Pack proved this, he took a Superflower 1200W Platinum and a Corsair 1200i Platinum.

    The Corsair was struggling to power three 290X cards whereas the Superflower unit powered four 290X without struggling. Huge difference on internal quality.

    Also as a bit of insider info, the Superflower Platinum units were actually built and engineered to meet Titanium specification and that is why they tend to do so well.

    Yes that is why next to the CiT unit I put a massive warning saying I DO NOT RECOMMEND, but its a perfect example of how ratings mean absolutely nothing, it is an absolute piece of junk! But there is a market for junk unfortunately........

    No coil whine on the PC I've just built with this PSU, it is powering a 2500K/GTX760 gaming rig & its for my nephew, it will be him that will be gaming with it & if it did have CW he wont hear it as he uses headphones.

    For 50 quid (black friday deal) first impressions of the golden green hx550 are good, considering I've bought a fair few Seasonics over the years.

    Very informative post here Gibbo, I like it. There are many brands on the market that claim to be the best, sadly most of these are ok, but not the best.

    I think you have summed up the best of the best out there on the market today. I would use any of the above PSU's personally (except that CIT lol). I was the buyer of PSU's at OcUK for almost 6 years as well so I know what kind of return rates all PSU brands have, including some of the other brands that are considered "good" - (NOT naming any of them though)

    Great post and further proof that if you skimp on the PSU in your build, you end up buying twice. You can't go wrong with a Superflower/Delta/Seasonic made PSU!

    Good info here, it does baffle me why people spend £600+ on there build then stick a cheap Chinese 600w PSU in it for £20 then it blows killing some of that money!

    Good to know my 1000W platinum Super Flower is on the approved list. I bought it to future-proof my power requirements and bought it while on offer, so sounds like a made a good investment :)

    Can I ask what "coil whine reduction technologies" means....is it actually new technology or is it just marketing speak for "we used other components" to make it sound like something special....or is it an actual researched and designed technology you have spent time and money on?

    Yes we had the factory try several different solutions for trying to reduce it, which they spent about a month doing and place the cards under sound testing. After researching several methods the best solution is what we have now.

    So yes we have invested money and the cards cost us more because so. :)
