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


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


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


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.

EVGA 600 W1, 80+ 600W Power Supply 100-W1-0600-K3 – £30.64 @ Amazon (£25.64 possible)

Extra £5 off possible using this: Amazon Assistant £5 off £25 spend This is an excellent price for a good brand of PSU. Lowest price since October 2015:

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.


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.


Full features here I always check the number of SATA connections and it has 6 (y)

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


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.


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


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.

And not the Vega 64?! Who you trying to kid!

This is a BARGAIN !!!! Best VFM in this 1000 watt psu bracket, going buy cost.


We use similar for mining machines for clients - I think there are GPUs available still like the RX series coming to a reasonable price again. I miss the days when I had just 12 GPUs as a test platform (only lowly and hot R9 290s, one per machine with low-tier PSUs) and was mining like 5 ETH a month, now you need like 5 times as much compute power just to match it!

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


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


Kinda. You can get the Mobo and Board for 176.99 and the PSU and Case for 79.96 so only a squid in it, and there's a load of other PSU/Casew combos. All under Today Only on the same linky

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 :{


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.


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.


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


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.

Cx750m corsair power supply on clearance £62.99 in maplin

Nice price for 750w semi-modular 80 plus bronze power supply
Get dealGet deal

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.


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.


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


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.


Can't seem to add to basket and no local stock shame

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.


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.


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!


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.

I've been looking at these, reviews say it can get quite noisy at high loads can anyone that has one confirm this?


Have the exact one. bought for £82 on Black Friday with free delivery. You won't go wrong with Seasonic - it's among the top brands in terms of quality and reliability


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.


Odd - this is showing up as "pre-order only" from Amazon with Prime - it is available from others already at a higher price, which doesn;t make much sense to me...!


cold - the picture quite clearly shows that these units are all upside down. no wonder they're flogging them cheap.

There's an APC for £50 that is possible smaller although probably not much in it. 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. I have plenty of UK and EU cables lying around. It's really not a problem to be honest. I usually order these things at cpcfarnell, which has free delivery on orders >5£:


Do you know of anything slightly cheaper and smaller? I only want mine to power a small router and a Raspberry Pi (basically so I can get notified if there is a power cut)


Complaining that it's got Schuko sockets? Consider this: edit: spelling


eek, thats a hell no for me then. thanks for the heads up :D

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.


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


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:


Unless I'm mistaken, the power requirement for a 1080ti is 600w? That's taken from the Nvidia website


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.


Have the 850w version, lucky people who got one, great psu and probably the best you'll get for 60.


Damn, too late and OOS


Been using this for a few months now, had a Corsair PSU which died on me, it's been fantastic so far - easy to install, quiet and cheap. Highly recommended.

"Currently Unavailable" Sounded like a good deal while it lasted!


You're welcome! I knew it this is a good deal. I received mine too, just about to put it in my secondary rig (i5-750,GTX 570:))


anyone received it? I received the first one today , the other was purchased under a different screen name. So far so good, testing it and I cannot spot a minimal fault and cannot hear any noise at all. Testing now with gtx 970 sli and also rx480 crossfire. Max current draw is no more than 560 at the highest peak and on gaming. Thank you once again OP for spotting this


It's been £70 or above most of the time - then a sudden drop to £60 a week or two ago (at just one supplier), then to £40. I'm still bemused by the fact that the 'top comment' in this thread is fiction and lies.


This could have been just a faulty one, doesn't mean all will be noisy.

I wouldn't. This EVGA is a SuperFlower SuperNOVA. Top tier OEM up there with Seasonic and Delta. That Corsair is some CWT made supply.

Best advice I've seen on here in ages.


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


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.


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 ;(
