Thanks people. Shall aim for the best I can afford with a minimum of tier 2.

pimpMe

And £42 from a store thats closing down, therefor no warranty, isnt cheaping out but is considered a bargain? Okaaay..

Josh_Graham

If you're slowly putting it together you'd be gutted if the system blew because of that old power supply, always try to get the best power supply you can it's simply not worth 'cheaping' out on

Kulaak

I don't see why lower tier psu's shouldn't work just as well as higher ones. You'll just be buying something that doesn't have as good a regulation, higher ripple noise, lower voltage stability, cheaper electronic parts (eg, capacitors) & probably will get warmer hence the need for a fan, a noisier one of course. Most of this won't matter tho' as it'll still or should perform within the specification guidelines but because it's built to a certain budget it may not last as long, however that's not to say it won't give many years of faultless use.

Careful there are some EVGA products in Tier 5 down to 7. Some people will have a nervous breakdown. Tier 1 for me and a 2 I think.

My point is you make it sound like not to buy one on offer and im sure there are plenty of bad psu's that cost £10 per 100w so thats why to me that rule of thumb is pretty pointless, it could just as easy lead someone astray.

HedgyHoggy

It makes perfect sense, if you are paying less then this then it means corners have been cut on components or manufacturing. Your PSU can kill everything else in your PC so why risk it for £10 a year more over a five-year lifespan? £10 per 100W is a rule of thumb that's been true for over a decade.

Not if your running a power hungry setup. Besides U NEVER EVER, run your PSU AT FULL LOAD !!!!!

delboyd

A PSU runs most efficiently at 50% load. My PC is around 400w full load (OC 4790k, OC 980ti, sound card, 3 HDD). Makes this the best choice. Anyone who gets this calibre of PSU is going to be building with substantial components, 250w GPUs etc.

zakkyb

This is the best deal for a PSU around £50 right now

Djrxx

power wise it may be over the top, but really you shouldn't scrimp on a psu.. Plenty of decent psu's in the £50 range, whatever your requirements, below that the saving just isnt worth it.. this is 60 odd percent more in price, seems a lot. But it sells elsewhere and until recently on amazon at nearly 300% of the price of one of those cheap psu's.. compared to anything at all on the market sub £100, this blows it out of the water. for a small increase you are getting a far far better psu than anything in that price range, 10 year warranty alone would be worth that, then add on the energy savings due to the platinum cert, and the fact this would cover nearly any future upgrades... HOT!

Unless you select discrete packaging or what ever they label it. I had a GTX1060 6GB turn up in the original sealed box and a sticker.

Going with the 2400g with build in graphics cant afford the gfx card atm maybe in the future also need more ram so money will likely go into that first. Excited with my first build so much choice out there its mind blowing appreciate the advice

taras

PS and LR, are not core hungry. I'd either look at the 2600 and a dedicated gfx card (photoshop does love gpus) or go for the 2400g and then upgrade next year (with the 2400g). The 1600 looks good too price wise .. I'd look at a low to midrange dedicated gpu with as much vram as possible (for ps & lr) Also the the 1700 maybe worth getting as that should sink to 200 shortly Depends on your budget

any VR good to run at least Full HD games yet? any idea? (cheeky) I have heard of Project Santa Cruz...maybe on market street I could invest some money,but not sure how to :{

EndlessWaves

I'm not an electrical engineer so I've no way of judging whether a flash is expected or not. From an outside perspective the different effects of the two failures could simply be due to different components failing. Where it mattered - not damaging anything else and failing cleanly instead of intermittently - it seems to have done it's job. For what it's worth I've owned both expensive and cheap power supplies. My current one is the Caseking/OcUK own brand version of Sirtec's SFX platform because the more recognised brands were taking the silly decision to equip their supposedly small form factor PSUs with cable braiding, which makes the cables less flexible and harder to get past the many obstacles in a tiny case. Said case cost me £170, so I wouldn't particularly call myself a cheapskate. I just don't buy into the whole 'buy it because the individual components are better' mentality. There have been many examples where such a mentality has developed and manufacturers have exploited it by over-speccing stuff past the point where it serves any function. Jewels in watches, overdrive systems on monitors, refresh rate on TVs and so on.

SpaceChip

I don't know much about VR, but as I understand it you need a decent gfx card (gpu) to power a VR set? Unless it runs off other hardware such as the PS4 version.

7fink7

do you recon peops could give up buying latest graphic cards if they would have virtual reality set? (skeptical) (pirate)

psycho_terror

it's not completely clear cut, but a good rule of thumb is that if a PSU can achieve higher efficiency, it's made with higher quality components. though it does depend on your usage, the efficiency gain of a gold or platinum certified PSU is almost definitely not worth it, but the quality it implies is. didn't actually see this linked anywhere, but this is the PSU Tier List that you'll hear mentioned in any PSU discussion.

Pure_Evil

Had the green one a while back. Clicking fan drove me mad. I had to open to replace. Could of just been mine though, but i seen quite a few posts when i googled. But thats the world i guess.

AngryCoffeeTable

each to their own, but a few years ago I had a client come to me with a faulty 'fresh' machine that he had owned for 6months built by one of the big UK etailers. It had a faulty CX750M. He contacted their RMA department and they sent him out a fresh factory sealed CX750M which also turned out to be faulty when I installed it for him. I offered to deal with the RMA service on his behalf but he didnt want to bother with the etailer so replaced the faulty power supply out of his own pocket with an EVGA SuperNova G1 650w which retailed for the same price as this current deal. The clients PC with the EVGA power supply is still going strong today although Its CPU is a few generations old. Googling the the CX750m at the time when i was seeking an alternative showed there were similar horror stories floating around so I just put it down to CWT doing a bad job rather than a retailer receiving a bad batch. At the same time, I have spoken to people who have had great success with the CX750M so for that reason I wont be voting on this deal. There are better power supplies that can be had for the same money which i would trust powering a high-end PC.

QwertyZzzz

Got this, soon will be 6 years, no problems so far. Great PSU.Super quiet and reliable +++

plewis00

Grey label CX750M was the only Corsair PSU I had to fail on me and it was the low-grade fan with a sleeve bearing that failed causing thermal shutdowns under moderate load. I would never buy this again... for not a lot more there are better EVGA Gold-rated models and a little more than that buys the vastly better RM series.

avoid budget psus because any possible problems will be invisible and could have very bad physical consequences, rather than just crashing. you want to a psu that's basically overcapacity for what you're doing. Personally I go for EVGA these days because of good warranty, my PSU came with a 10 year warranty.

Woodzta

Even a starving hamster could feed a 1050 Ti! The 1050/1050ti cards are ideal for just plugging into many cheap pre-builds because of the low power-draw, simple connection, cheap prices, and huge gains. You won't be proving much by successfully running it on a CX500 "500w" PSU. At least not unless it kicks the bucket shortly after. It's a good brand with a decent reputation selling a budget quality product. However, for you, with a 1050 Ti, your risk is low, and really what it comes down to. If you plan on doing anything intensive with well-performing hardware, then the majority of PSUs under £30 aren't just "budget", they're dangerous.

ScotBoy

My power supply arrived today. Someone earlier in the thread described it as a lightweight supply. Believe me, it is anything but. First impressions are it is a quality build. The cables are plenty long enough and they provide a cable tie kit for management. I chose to avoid budget, sub-£30 power supplies. But, I could not justify a £80+ supply. First impressions are that this fits my needs perfectly. It really does look like a quality bit of kit. But, i haven't used it yet. As I said before, if it doesn't stand up to the demand, it will go back and I will learn a lesson. Based on what I have seen so far, it is pucker!

Krytten

Having worked at a major PC component retailer, and seeing the amount of cheaper PSUs that got returned after going bang (even from big brand names). Believe me there's a reason they are cheaper.

Far better ripple suppression which results in more reliable overclocking, not to mention making the unit itself more reliable as the caps have to do less work.

There's an APC for £50 that is possible smaller although probably not much in it. https://www.ebuyer.com/703990-apc-back-ups-300-watts-500-va-3-x-c13-input-bx500ci Just check as to whether the model you're after supports some form of alarm or notifications... this one above doesn't have notification but the one I first listed comes with a usb lead and basic software that allows a PC to pop up an alert if power cuts or fluctuates. but I don't think it can send email alerts or such like. The cheaper UPS tend to be quite basic in what alerts they offer.

Exactly what I had thought: just buy either Schuko power cables or travel adapters. As an expat immigrant about half my devices have a Schuko plug or power cable.

So if a platinum 400W PSU is £100, and a gold 400W PSU is £60, then you run them both at full power continuously... It will take 7 years for the platinum power supply to make up the difference in price. (89% efficiency at 100% load for gold, 90% for platinum so about 5W difference at 100% load, 15p/kwh) Now extra warranty length? That may be worthwhile.

codnan

That’s recomended by nvidia , the 1080ti would never draw more than about 350-400w and much less most the time . still voted cold tho as you could get a decent 650w Seasonic psu for less than this and psu noise has never bothered me at all (never even noticed it over system fans

Felicitous

if you're building anything that would require modular PSU I would be surprised to see a build need as little as 400, I think im pushing my luck running 600 D:

Tiny25

Unless I'm mistaken, the power requirement for a 1080ti is 600w? That's taken from the Nvidia website http://www.nvidia.com/content/geforce-gtx/GTX_1080_Ti_User_Guide.pdf

GAVINLEWISHUKD

But high power PSU's are far less efficient when run at low loads. Personally 396w on the 12v+ rail is plenty for somebody wanting a low noise system. It's enough for a i7 with 1080ti system. You are paying a premium price for a premium product. If you are paying over £1k for your system I don't see spending 10% on a PSU as a massive ask. You would spend that on a £400 system?

I just retired my Coolermaster psu last year after 9 years of trouble free service and at the time it was powering a high end quad core 9550. Only had to change due to a GPU upgrade but they are decent budget power supplies in my opinion. Only cost £30 back in 2008. Got a modular Corsair with a 10 year warranty now which is silent but would recommend Coolermaster powers supplies if funds are limited.

Was this price at eBuyer when I ordered two on Saturday. Not available any more so perhaps a brief price match?

Gkains

But aside from the EVGA badge (and if something goes wrong their customer service which is meant to be quite good), this GQ supply has nothing to do with your G3 Supernova. Yours is made by the top-notch SuperFlower. This is made by FSP. Who can be okay, but I would never compare them to SuperFlower or Seasonic.

pogux

Just a warning to anyone looking to potentially upgrade their PSU, make sure you use the cables that come with the new PSU! Modular power supplies don't have standard pinouts - I wasn't aware of this and blew up all of my hard drives and LED fans a few weeks ago by leaving in the cables that came with my previous Corsair power supply ;(
