It wouldn't just struggle, it'd outright fail given my 4 slice toaster is 1.8kw. Thankfully a PC power supply is only required to deliver power to computing components not burn bread until it's toasted so the power requirements are much lower. Say 90w for the CPU and 200w for a GPU + other components can happily suffice with a 430w PSU. If you want to make toast as well it's probably better to invest in a separate toaster.

As for future proof power requirements if anything are coming down.

I'm confused - is this the same PSU that's £19.50 on the Today only Deals page? This one says it's part of a bundle but I can't work out what that bundle is. Also you have to add delivery. (It's early so I may have missed something!)

Im not sure about the bundle thing, but i just bought one to replace a failed corsair cx unit in a friends pc and it went through fine by itself.

Cheapest delivery is 4 quid

OK looks like a good deal - I think this is nearer £40 normally! Some forum members can get free delivery if they spend 20 before VAT.

how strange, why does it come with only one PCI-e connection?? I know can be added by there must be a good reason for this, almost all cards in the market got 2 for single card

Low and some mid-end GPU's just have 1 connector as this was probably designed for those types of users.

so, how much is this designed for gamers?? despite the higher consumption, would this still be efficient to run a gpu with 2 pci-e connections in a proper manner? by adding an extra adaptor of course

You could run an Intel + GTX 970 build with this. You'd need a Molex to PCI-E connector though.

450w would struggle to run a toaster. You want 500W minimum, 600-650 is better, 750 if you want to future proof. Look for a long warranty too. Evga do a 10 year on some.

If you're paying 20 quid for a PSU, i don't think you're gonna have a parts requiring over 500 watts, let alone a care about future proofing.
430's perfectly acceptable for a lower or well-chosen mid-range.

You are wrong I am using the new corsair 650rmx psu and its running a 3770k and 2x 970s and the fan has never turned on as yet. A good psu at 230v should be able to run well beyond its specs as these are tested at 115v

Psu's are at their most efficient when at 50% load. If your PC is drawing 350 watts at full tilt a 700w power supply would be most ideal
rev6 to washer010
6 Feb 16 #21
With 80 Plus, it's very similar. 50% and 100% load will be at 80% efficiency, give or take 1/2%.

Cannot, just re-tested my gtx970 with a platinum AX1200i. Does use up to 370w (520w sli)and 300w with a gtx 660. Would destroy this psu in short time and possibly damage other components.
. the only O.C applied is on the 3770k at 4400mhz. Note that I got a device that measure any wattage up to 13amp. So, a minimum required would be at least a good 80plus 500watts to be on the safer side and 550w for an amd 290 the very minimum.
I must add , for the people using top of the range older cards, to use something better than this or an higher wattage or you will damage your components too.

COLD. Anything under 500w should no longer be manufactured!
BigYoSpeck to zworld
6 Feb 16 2 #26
Totally! The system I've just built for instance that only needed a 250w PSU I could just have sawn a 500w unit in half for and then had a spare I guess.
jewelie to zworld
6 Feb 16 #27
Given that PSUs can be quite inefficient at low power, I disagree.
Weenie Beenie to zworld
6 Feb 16 #29
Utter nonsense. Why would you need 500w for example on an office use computer with no dedicated GPU or anything else power demanding? Even with dedicated GPUs not all of them have huge requirements, many are less than 100W and with everything else that means 400w is usually perfectly sufficient.
keepitonthelow to zworld
6 Feb 16 #36
Another one who has no clue so your telling me a platinum rated 350w psu is worse then a 80 plus pow psu I know which one I would pick.
bobo53
6 Feb 16 #28
not my type but at £19.99 inc. postage I would have bought it just to keep as a spare and mainly testing. For a rated low power GPU, max 100/120w, this is the ideal for the people that do not care about efficiency and energy savings
zworld
6 Feb 16 #30
Surely I didn't mean the light office users. They can do with a 200W PAU
Weenie Beenie
6 Feb 16 #31
Ok, how about an i5 build with a GTX 750ti, with a power usage of just 60W? Why would that need 500W, 400w would be fine.

Good find - is it powerful enough to run this set up?

CPU
Intel Core i5 3330 @ 3.00GHz

RAM
8.00GB Dual-Channel DDR3 @ 799MHz (11-11-11-28)

Motherboard
MSI B75MA-P45 (MS-7798) (SOCKET 0)

Graphics
1024MB ATI AMD Radeon HD 7800 Series (MSI)

Are any of the cheaper (eek!) standalone cases on Scan worth buying? I'm thinking about rebuilding my PC and donating the innards of my current build to my Sister. Many thanks :smiley:
bobo53 to ValiantSaint
7 Feb 16 1 #42
just about but I would recommend a 550w to be on the safe side 500w at worse. A system cannot be run to the limit or near at all times.

I just use a psu that works i had one that got so hot i had to wait to touch the case because the fan wasn't always spinning then just chucked another psu in and carried on dont see what the big deal is just buy a psu.

7 Feb 16 #41
Millions of PCs in the world are powered by cheapo PSUs. If they didn't work, the failure/return rate would make them uneconomical. I'm a bit bewildered by PSU elitism, but at the same time, you can buy apparently decent quality units at cheap prices - like this one - so probably better to be safe than sorry?
ValiantSaint
7 Feb 16 #43
Thanks for the reply. I've just popped everything into a PSU wattage calculator and it's given me a needed wattage of around 370w - http://outervision.com/b/91Lqmd (Can this be trusted?) :smiley:
bobo53
7 Feb 16 1 #44
No in my opinion and if you O.C. it will jump up another 10-15%, on the top of that you need to add another minimum 10% for safety. This psu will do it but it is just a standard basic non quality 80 plus PSU, do not expect much but you can still run your system until it might start to get faulty and drop frames until it will burn. I tested my system yesterday with a corsair ax1200 platinum psu (top quality), it does use up to 370w with a gtx970 and I would expect this psu to use over 410W in comparison (the difference in efficiency) Your card is also rated at 175watts against mine at 150watts, so, add another 12%. remember that platinum or 80 plus is all about efficiency and not assurance of quality and do not expect much at £20.
If you are desperate to spend a little just go for it but will be a false investment in your situation, with £35-40 you got a wider better choices with more capable basic PSU's apart from the fact that you also get extra cables and surely a second proper PCI-e connection, this one only got one, so think about it as a non proper gaming PSU. If it was postage free I would have bought one for testing and keep as a spare.
this could be a much better option https://www.scan.co.uk/products/600w-evga-100-w1-0600-k3-80plus-atx-psu-single-plus12v-rail-120mm-quiet-fan?utm_source=google+shopping&utm_medium=cpc&gclid=CODg8bm45coCFUn4wgod2moI4g
still not a superior quality but it will feed your pc in a proper manner, also remember you change it once for all of your future needs and as an investment I would take a good quality better when it comes to the psu. People does not think twice to spend 100's of pounds every few years on a GPU or even a new system but they forget that without a good psu the system sometime does not give the best. A psu suppose to be for life, virtually the only thing that does not need any upgrades at all, for the rest we all know we always want the upgrades when they come out and the market is very tempting.

7 Feb 16 1 #45
This would Be ok though I would go for 500w to be safe.
I ran an i5 2500k and sapphire 7770 on a 400w potato no problem
ValiantSaint
7 Feb 16 1 #46
Thanks again for the amazing replies. All I need is a PSU (and a case!) so I can throw in the listed components for my Sister, who's without a PC at the moment. No OC'ing etc. All she plays is point-and-click adventures! :smiley:

7 Feb 16 #47
Thanks for the advice
Yes I know wattage is only one consideration, as some cheap PSUs (Ace, etc) may advertise higher max wattage but give you less in reality
