It isn't just the psu in isolation; how much are your other components drawing?
#3
that is a very cheap and basic psu, be nice to your pc and give it a new lung, lol
#4
Get a new PSU would be my advice.

Cheapest 4870 512MB is £85 @ OCUK unless you know of a cheaper one? Not sure about the 1GB.
#5
New PSU time
#6
so it won't run with this cheap psu, the other specs for my com are 8gb ram, 500gb hard drive, quad core phenom,
#7
Buy a decent 600w PSU and when you sell your PC You can remove it and put it in your next PC,That way you should never have to buy anothe rand your PC will be quieter and there will be a lot less chance of frying your HDD with all your data on,

ATI recommend a 500 Watt or greater power supply with two 75W 6-pin PCI Express® power connectors. Yours is not really close enough - its supposedly 450W but only 240W on the 12V rail which nearly all the current is drawn from these days. It looks like it might not be an ATX size power supply though - so you may struggle to find a suitable PSU for the case you have. Also the card will dissipate a lot of heat and if its a very small, compact case it may cause overheating problems...

any cheap psu, dont want to spend alot...
#11
my case is the normal size so don't think i have a problem there, just need to look for a good psu. Anyone know any for £40 max
#12
there are cheap ones on ebay won't they do? They are 600w

Biggest & most common mistake people make building PC's is putting in a crap PSU. Do you really want to risk a crappy PSU from eBay taking out all those expensive components?

I wouldn't personally consider anything less than an Antec or equivalent.
#14
PSU's aren't the sort of thing that you want to go cost cutting on TBH, I can appreciate budgets but by buying a decent PSU for a bit extra gives you piece of mind that it's very unlikely to take out your whole system.

Wattage is never an indication of how a PSU will perform; looking at how many amps it has on the 12V rail is an indicator though.
#16
Cheap psu's are the route to 90% of all issues with pc's. Get a good branded one. Cleaner power will make ur components last longer too, NEVER skimp on a psu!

You sure? Really doesn't look like a normal PSU to me from that pic, the orientation of the sticker is weird - but could just be a deceptive picture... Is the back of the case (where the power cable goes in) the bottom of the picture?

Yes think it is. Think its one of the cases that has the structure on to a flat case side and the other side and top is all in one in a sort of upside down 'L' shape.

Cool, I think I know what you mean! Worth considering that most high-wattage PSU's these days have the fan on the bottom, not usually a problem but it can be in some cases. Finding high-power PSUs with fans on the rear is very hard these days, had to source a dozen recently and it was not an easy or cheap job!

There are quite a few decent PSUs for around the £50 mark, I'd be wary of spending any less unless its a special sale price. Its well worth getting an 80plus one if you can, they produce significantly less waste heat (a 70% efficient will produce 150W of waste heat at 500W output, an 85% will only produce 75W..)
#20
i don't know what you mean but will post pics, the fan comes at the rear of the case

Its fine, ignore me, any ATX PSU should fit and work fine in your case from those pics... :thumbsup:
#23
thanx for all the help, what about this psu:http://www.ebuyer.com/product/102994. I know its cheap but has over 100 good reviews

Or should i get tonys recommendation:http://www.ebuyer.com/product/167200
#24
Ignore the reviews - look at the ratings. 12V = 20A, no better than your current PSU, not enough to power the GPU and CPU comfortably (a Phenom quad will happily drink over 120W (10A on the 12V rail) at max load - leaving only 10A for the graphics card, drives, fans and rest of the motherboard. Not enough to run stably.)

The second option is quite a bit better, but still not as good as other high-efficiency options (70% efficiency = 150W waste heat at 500W load remember - thats like adding two old lightbulbs worth of heat to the case). If you pay for electricity, thats basically getting close to 1p extra per hour to run over a 80plus PSU - might not sound that much but if the computer is on 24/7 it would be well over £50 per year extra in electricity costs!
#25
just read your efficiency...so not the 1st one then
#26
reccomend me one please
#27
Just having a look now. Personally I'd be looking for at absolute min 25A on combined 12V rails (ideally 30A or more), a recognised brand and 80+ certification, but you probably won't find all that for less that £50... That said, building a PC is a balancing act and its daft spending hundreds on a graphics card and not having adequate power for it...
#28
upto £60 then

what about OCZ:http://www.ebuyer.com/product/127861

still 18A...

cant find 25A

Nope, thats got 4 different 12V rails, each of which can provide upto 18A, so that would be more than enough... Lots of PSUs have more than one 12V rails, splitting the workload so to speak (usually one powers CPU, then one or more powers the graphics and other peripherals). Other designs just have 1 rail (like your current one).

is this perfect for my system

just saw a youtube video of it seems very loud

Here's the acoustic graph from anandtech (not for that actual model but for others in the series)
http://images.anandtech.com/reviews/psu/2008/enermaxpro82modu82/acoustics.png

Seems they are pretty silent up to 50% or so of load, then ramp up to a moderate volume. I'd guess when you're not gaming your system should fall below 50% (200W or thereabouts) so its only likely to be noisy when you're gaming - and in those circumstances the graphics card fan will also likely be pretty loud anyway.

Unfortunately high-end graphics and silent operation are two things that don't really go hand in hand and compromise has to be made - there are probably quieter PSUs for a bit more but I'd also expect the cheaper, lower efficiency models to be noisier than this (the less efficient the PSU is, the harder the fans have to be run to disperse the heat so the more noise will be produced...)

No worries just bought the ocz for £60. Anyway thanks for everything. The deal i was talking about for the graphics card is an XFX HD 4870 1GB DDR5 for £90. Here is the link: http://www.hotukdeals.com/item/473929/xfx-hd-4870-1gb-ddr5-84-99-delivery
