Be sure to register your PSU straight away, as you will have to disconnect everything to get to the serial number.

I would definitely pay the comparable extra £20 for an extra 7 year warranty over competitors. Less landfill waste too

I'm liking that we don't need to buy 800w+ PSU's anymore. So glad things like SLI/Crossfire have gone and CPU's / GPU's use less and less these days.
Wow 12 year warranty! That's real confidence in your product.

I have this PSU , its absolutely brilliant.
And at a very a good price too, as its at £178.58 on AmazonUK currently..

amazon.co.uk/Sea…SES
What's the bottom on the side do???
It's on preorder now, but at an even lower price at £99.98!

I know right, and it'll continue to drop, meaning PSU's like these won't need to be replaced.

The black one is also at the same price, Seasonic 650 Watt

the seasonic PSU have all went up in price the past couple of weeks, the 850w versions are a joke at the moment apart from the older Focus range which can be had for £130ish but after the new version or prime Plat but there all over priced

At this price I agree it makes sense for the peace of mind and I voted hot. That said, at it's regular price it makes no sense at all IMHO.

Also the whole thing about landfill doesn't always play out that way. PSUs don't necessarily fail when their warranty is up, I'd say provided they are by a reputable manufacturer and not abused they can often outlast their warranty often by several years. Many even far lower tier PSUs than this can last for 10+ years even though their warranty is far less, couple this with the fact a PSU is not really something you upgrade in the same way you do a GPU or CPU, most people will only replace them when they die or move to a whole new system. Of course, self builders might even use the same PSU over several systems to save money to put towards upgrading the other parts....

Well said, my last 3 PC's were budget base units and they all still power up from the last 15 years lol. If you keep good ventilation and don't overload the power rating this is not uncommon...

£105 for just a PSU is wasteful unless your PC build is what £1200 upwards? And since when did dropping that kind of cash on your build make VFM sense in this age of 2019 lol.
WTF is this?... do I need it in my life ?
Now we've stopped using the PSU as the sole exhaust for the computer they rarely fail (assuming you bought a reputable brand). The immense heat from a P4 chip exiting through your PSU wasn't going to end well!
The semi-passive PSUs don't kick their fans in until they hit roughly 50C and given how rarely the fans kick in when you have a correctly ventilated case shows they get very little heat to damage the capacitors etc.

I think you are right about cooling being a lot better now, but I think the Pentium 4 effect has been overstated. P4s produced a fair bit more heat than AMD's CPUs at the time - over 100W TDP compared to about 70W for Athlons. But Intel processors have had higher TDP models than the P4s maximum TDP from the 1st gen i7 all the way to the current gen.
The black looks nice. I'm liking that design.

I'd never heard of Seasonic until I started looking at PSU quality tables, they come up top. I'm not sure how up-to-date they're kept but I narrowly avoided some nasty PSU purchases thanks to the ranking tables. Some of the popular PSUs on Amazon rate very poorly and despite usually working out of the box, should probably be avoided.

You need to factor in the extra you have spent on electricity over the course of those fifteen years due to lower efficiency. A cheap PSU can be expensive in a total cost of ownership calculation.

Seasonic are definitely up there with the best PSUs you can get, although at the top end there's little to separate the companies. 10 years ago when Seasonic were trying to establish themselves there were some fantastic bargains to be had because they were an unknown brand despite being the OEM for pretty much every PSU brand on the market.

Simple test of PSU quality remains to be the weight test, if it weighs close to 2Kg in the 500w range it should be good quality. I've had cheap 650w PSUs that weighed less than the box they came in and significantly less than a 350w Seasonic PSU.
Ordered always wanted a snow machine.

If you like snow, get this. Keep your ski goggles ready
Sound like the Gold EVGA ones, that offer Eco Mode and don't fire the fan up until it reaches a certain power threshold.

True; but in perspective, the heat generated by P4 was nothing compared to some of the high-end cpu's these days...
Such as you correctly mentioned the first gen i7 (130w tdp), and more recently the i7-9800x (165w tdp), and especially the Core i9 series.

Lest I do disservice to Intel, let us also never forget the monstrosity that was the AMD Piledriver FX-series, specifically the FX-9590, which was just a brute-force cpu with a 220w tdp, which was mostly beaten by the i7-4770k (84w tdp)!
Gutted. It’s not actually a snow machine is it? I got really excited for a minute. No idea what it actually is tho
Good quality PSU, hot

GPUs are drawing loads more power than before. CPU probably becoming more efficient over time. But the power drop is not as much as you think.

The main drop from wattage is lack of HDD, CD or DVDs. These mechanical drives need fair bit of power.

To drive the main board (chipset), CPU, Memory etc you need various voltages 12v, 5V Texans they need fair bit of juice. Then add on a top of the range GFX card your 650 is going to be lacking.

Also if people run AIO or custom water cooling loops then there will need to be some power on the 5V line as well.

The closer your system power draw is to the max power rating the more likely the MOSFET will degrade and fail over time. Like all silicons there are built in silicon duty cycles. So probably still good idea to go a bit more than you need.

My rule of thumb is between 1.5X or 2x the actual system draw. But really depend on which volt line you system is drawing most power from. When overclocking CPU and RAM those volt lines need to be rock solid. And thus you probably end up needing 800/850w PSU to satisfy the power requirement on a particular volt line.

Strangely I had an Antec PSU fail just outside warranty. Didn't expect it as I bought it because Antec is a well respected brand. Bad luck I guess, or perhaps my overclocking was taking more of a toll than I thought.

I have the tx 650 psu. Previously I had gtx 1070 gaming edition with 2 x 8 pin connector and 2 fans.

Then I upgraded to gtx 1080 founders edition to find out it only has 1 x 8 pin connector. I feel like its giving me worse performance than the tuned 1070 did.

As it's only 8 pin will it be better to put in my corsair 1050w psu I still haven't used yet? Will it give more power to the 1080 via single 8 pin connector?

If the card only has one 8pin it probably depend on what the max power output the pin can support. What you have experienced may well be the volt lines dropping slightly due to higher amp draw. Have you done some bench marks to compare the synthetic numbers?

No I haven't. Only utility I run is hwmonitor just to measure temps. I do have 3 other PSU's. The corsair HX 1050, a corsair CX 750w psu and a cooler master 500w bronze psu.

My 500 W EVGA failed after 6 months use. Longevity varies depending on how close you are to maximum Wattage. I was close due to overclocked CPU and gtx 1060 gpu, and all those external peripherals pushed it to nearly maximum. As someone else suggested, go over your planned Watts by at least 50% and it'll be fine. Or buy one like this with high Watts and eco mode and you'll be fine.

Or you just got a duff one, even if manufacturers had a 99.9% success rate that still leaves hundreds or thousands of units with manufacturing defects.
PSUs are most efficient at high load so size to leave about 100w of headroom when the system is at full load.
Seasonic are a good brand. I’ve a different one of their PSUs; very quiet indeed.
