Reccomend me a PSU for under £80 in UK - Page 3

It says "System Wattage with GPU in FULL Stress = 307W".

 

Study it a little more carefully with an open mind to the possibility that I might be right.

 

 

Edit:  The reason why they recommend 550W minimum is they are taking into consideration the purchase (or ownership) of 550w PEAK-rated power supplies.  These kind of PSUs would have a continuous capacity of 425-450w at the most.

i would say only one thing a 450w would be ok if as wat you claim but a 500w is atleast required in my suggestion for some overhead thumb.gif

It sounds to me like they should be avoided.

Anyway, here are some PSU's that I can recommend.  I am using Scan.co.uk because it seems they always have the best selection and prices (all prices include VAT):

Sorted by 300 - 530W (non-modular):




Sorted by 550W - 580W (non-modular):




Sorted by Full Modular 550W - 900W:




Sorted by Hybrid Modular 300W - 500W:




I admit that I would be overwhelmed if I were faced with all of these choices and I would even want someone to just tell me which one to get.  For me, I would definitely prefer a modular power supply because they are easier to install, and cable management is much easier as well.  Of course, I would also want one that has at least two PCI-E cables because many video cards require at least two 6-pin cables connected to it.

Out of the 5 modular PSUs here, there are three that I would prefer to consider because they have two 6+2-pin PCI-E cables (it's compatible with both 6-pin and 8-pin connectors)  The PSUs I'm talking about are the 480W Be Quiet! Straight Power E9 CM, the 500W PC Power & Cooling Silencer MK III, and the 530W Be Quiet! Pure Power L8.  Out of these 3, my choice would definitely be the 480W Be Quiet! Straight Power E9 CM.

If I were going for a non-modular PSU, then my first choice would be the 550W NZXT HALE90 because I know that it is a top-of-the-line unit, and I also noticed that it has two 6+2-pin PCI-E cables, and two 6-pin PCI-E cables!  Yeah, 4!  Of course, it would be better if this were a modular PSU with this many cables.  My other choices would be any that have at least two 6+2-pin PCI-E cables because that makes it compatible with both 6 and 8-pin connectors.

I could have recommended a larger number of "smaller" PSUs than this, but I am trying to keep it open for big future upgrades.  So, the 380W SeaSonic S12II can really only be purchased if you know that it will always be enough in terms of power capacity and connectors.  Based on what you said so far, I think it would be, but then of course I'm not you so I can't really know for sure.

I'd suggest a semi-modular approach as it saves money (or in this case gets you a better PSU), that and you generally use all of the cables or all of them minus 1. I'd suggest the Seasonic MK12II 520W that is semi modular in this case. The extra connectors and ability to remove them is nice and it has enough power for the time being and a bit to spare.

There's plenty of overhead in a quality-made 450W power supply, even a quality-made 400W unit.  How?  Because they are able to continuously deliver 400 and 450W 24/7 if need be.  However, they would never need to because again, that 388W figure is unrealistically high.  Plus, it's a calculation for having a full load on both the GTX 680 and the CPU at the same time.  How often does that happen?

 

So again, a more realistic maximum power draw would top out at around 350W, maybe 375W - and you'd have to put some effort into getting the power draw that high.

 

The most I have ever seen my sig pulling from my PSU is about 360W (about 425W from the wall, and I have a GTX 580 which requires a bit more power than the GTX 680!  In order to get this power draw, I had to run Furmark using its most intense settings.

 

So, I hope you are beginning to see why I can confidently say that a quality-made 400W power supply would be enough to power a system that has one GTX 680 in it.  Get a good 450W power supply if you intend to overclock the GTX 680 in addition to CPU.

Out of those modular PSUs, the 520W SeaSonic M12II is the worst in my opinion in terms of connectors.  I mean, I'm mostly concerned about the number of PCI-E cables:

 

 

 

Not only that, but the +12V capacity of the 480w Be Quiet! Straight Power E9 CM is only 24W less than the 520w SeaSonic M12II (456W vs. 480W).  The +12V capacity of the Silencer MK III's +12V capacity matches the Be Quiet's of 456W, and the other two are 480W (for both the 530W Be Quiet Pure Power L8 and the 520W Antec NEO ECO Cable Management Series).

 

So with the 480W Be Quiet Straight Power E9 CM, you get a high quality modular PSU that has two 6+2-pin cables, and a nice +12V capacity of 456W.  For future build plans if never having more than one mid-range video card, this should last "forever".

The Silencer MKIII 500 and E9 480 (suggested by TwoCables above) make excellent options, the G-550 from Seasonic even more so (provided it's not considerably more expensive)... but looking at your list, the ZT 550 seems to be the best deal (not the quietest solution though... if silence is your main concern than you should probably go for the E9 from BeQuiet!).

List further whittled down to

PC Power & Cooling Silencer Mk III Series 500W £60
be quiet! Pure Power L8 CM 530W Power Supply (PSU) £60
be quiet! Pure Power L8 CM 630W Power Supply (PSU) £63
PC Power & Cooling Silencer Mk III Series 600W £70
Seasonic G550 £77
be quiet! BN197 Straight Power E9 CM 480W Power Supply (PSU) £78


How does the E9 Be Quiet! compare to the Seasonic G550?
post #29 of 32
It's inferior in all regards except looks (subjective) and noise output (it's by far the quietest on the list).

So if you were to rank the psu's, how would you rank the list from 1 to 6?

Thanks for your input.
