Seasonic FOCUS Plus Platinum 650W (80+Platinum, ATX 12V) PSU/Power Supply - Black

I bought a new graphics card (Sapphire Pulse Vega 56) which didn't work with my old PSU (PurePower 680W). The card needs newer style 8 pin PCI power cables (x2) which my old PSU didn't have. I tried with the x2 6 pin power cables but no joy. Nothing to do with lack of power, the card is just fussy.This Platinum 750 was a breeze to install. I think the cables are great - all covered with flexible braided black material and both ends are labelled so you can't really go wrong. Many are x/y (or x+y - same thing) meaning a block of x holes for older motherboards and a decoupled one (2 holes) for newer motherboards, so you can use just x holes or x+y holes. eg the PCI cables are 6/2; use just 6 or plug the other one in for 8.To untangle my old PSU I simply unplugged one cable from the motherboard and replaced it with the corresponding cable from the new PSU. Repeat until all replaced - no mistakes can be made and no need for the motherboard manual thinking "where's that connector?!".When doing motherboard work remember to pull the mains cable out first, then press the power button on the PC to drain away residual current stored in capacitors. Mine had enough left to spin up the CPU fan and graphics card for a second.It is really quiet. The fan hardly comes on. Even running Folding At Home using both my new graphics card and my Intel i7 6700k 4Ghz the fan rarely comes on and when it does it's more for a waft than a hovercraft belt of air. My system is typical with a few SSD drives, one HD, a DVD, and the new graphics card (running 95% doing the F@H work). I honestly don't need 750W but it had a price reduction at the time.There's a button on the unit which makes the fan run idly at all times if you wish.It all feels very well made and is well packaged and presented. The PSU comes in a black drawstring bag nestled in sturdy a foam tray. Comes with a manual which I haven't read yet. Unhelpful I know, but helpful in that you don't need to read it to get your system up and running.It came with a UK power cord and plenty of cables for me (I had a few left over). Importantly it had 6/2 pin PCI (x2) cables and x2 SATA cables (each with 4 heads).6 pin PCI was designed for 75W. 8 pin PCI are rated for 150W. You can buy adapters to convert 6 pin to 8 pin but they wont magically increase your PSU electronics to deliver 150W.That's why my new graphics card wouldn't come on - it knew my PSU couldn't deliver more than 75W so refused to budge even though it doesn't need all that juice when idle. A sensible strategy - it needs a horse not a pony.I love the modular style. Having only the cables you need inside the PC makes it less cluttered and helps with the air flow. My old PSU in contrast was an explosion of cables to cover really old motherboards and (at the time) newer ones.For full spec and list of cables I suggest going onto seasonic dot com into the focus-plus-platinum path and you'll find detailed information including easy to understand cable schematics - technical drawings rather than hard to fathom photos of curled up distant cables.I'm impressed with the quality of this PSU and their website; it's the latter that made my mind up, knowing exactly what cables I was getting. 10 year warranty too.

Buying a cheap PSU for your PC build makes about as much sense as buying retread tyres for your car. In both cases you're trusting something valuable to a critical but cut-price component. Seasonic may not be the cheapest make out there but, unlike other well-known brands, the name on the box is the name of the manufacturer.This PSU has a 10-year warranty, which encourages confidence in its quality. It's fully modular, so you can power your build with the minimum number of cables. You can choose the fan profile by means of a switch, choosing whether to have the fan stop at low temperatures or run continuously. It's so quiet that I've chosen to run it all the time.Checking the voltages with CPUID's HWMonitor reveals that they are all extremely close to their rated values.In summary, I'm very pleased with this PSU. It really shows that you get what you pay for.

Haven't been able to finish the build using this PSU yet, I've found the build quality to be great and a lot of care has been taken with the packaging and cables using a hard cardboard box and cloth bags.I am however quite disappointed that the power cable that came with the PSU was in fact a European plug and not a UK plug, I know its only around £5 to buy a new one but its still a price I was anticipating, I assumed that because it was being sent from the UK to the UK it would be packed with a UK plug. I feel like the plug type needs to be specified in the product description.Ill probably post an updated review once I actually get it running.

Pleased with this power supply! Props to the seller for delivering this power supply much earlier than scheduled!Things that I like about this power supply;Fully modular power supply, meaning that there's going to be better airflow within a case and less messy in general.Very quiet, in fact, don't hear it at all.Love the hybrid feature that keeps the fans off until a certain load is met.The only downside would be that the 24-pin ATX cable was quite stiff, a bit challenging to adjust it as you want it to be, but hey, apart from that, great!

I bought this to replace my perfectly functioning 10 years old Seasonic M12 750w due to upgrading my GTX1080 to a 1080ti and the PSU running a little noisier at load than preferred (I have a very low noise PC).It was between this and the Corsair 850w RMX. Either one of these PSUs are capable of almost silent operation up to and over 500w+, so both would have achieved exactly what was required with ease. I simply went with this one as I hold a little more trust in Seasonic's Platinum designs over the CWT OEM built Corsair. But it was a close call. The fact that my old Seasonic PSU is still going strong is probably the bias that swayed me.

I had this drive upgrading from a cheap >£20 Chinese power supply I had before because I wanted to be sure I won't one day fry my computer parts and I also wanted the modularity so I can reduce cable clutter in my new case. This does both of the above. The 10 year warranty makes me confident that Seasonic really are sure about this power supply, and it's done me well so far. Not heard anything bad about this company from anyone else either.

I brought this because my corsair psu started making a noise really annoying so I upgraded to this one, personally I wanted the 700w gold but amazon had sold out so brought this one.. Great psu very energy efficient love the hybrid feature however I keep the fan on as it really will get hot in hybrid mode!! Even with the fan always on I can't here anything it's silent 😶.

Mine came with a UK plug which was nice.It has a Hybrid Mode option (push a button on rear to switch modes) which only spins up the fans when it's drawing over 40% power or there abouts, so its totally silent otherwise for most of the time.Enough cables and stuff to get my machine all hooked up so i'm happy. :-)
