    ebuyer.com/pro…561

    I want a power supply that is future proof, but im not sure whether to go with this, the OCZ gamextreme or somewthing else...

    Thanks in advance

    (Rep for any good answers )

    Your best bet for information and recommendations is probably [url]www.tomshardware.com[/url] although, bear in mind, it's mostly US.

    If you want UK advice, try [url]www.avforums.com[/url]. I think that you're likely to be better off asking on a specialist forum rather than here.

    Better Power Supply for what? The AOpen one only has 40A on the +12v line and just four PCI-E connectors so I guess it's not for an ultimate gaming PC but it does have hefty +5v and +3.3v lines so maybe you're planning some sort of server?

    Dont really know much about Psu's, but this isnt going to be powering a server, im not in the market for one just yet.
    This is looking to power, a quad core AMD, a tb hdd and a gtx 275 xxx.

    I just want to future proof my pc, just in case i decide to get another gtx ;).

    and my current psu keeps being overloaded.

    Then why are you looking at 1000W PSUs? That's the sort of thing you'd need if you wanted to add three more GTX 275s, not just one.

    Your system right now would be fine on a 450W PSU and a 550-650W PSU will give you plenty of room for adding another GTX 275 and any other bits you want.

    As for top quality I've heard the Seasonic X-650 is very good but if you don't want to splash out on that then you should be able to find something good in that power range for £60-70, or a bit more if you want a modular one.

    Im on a 550watt right now and it keeps cutting out under load mate. 1000watt to power three sounds fairly far-fetched in my state.

    I might go for the 850watt Gamextreme Ocz, although its not modular, it definetly has the quality and the power to keep me going, just this thing's cheaper, modular and seemingly more powerful...

    A good 550W definitely shouldn't be failing with load. It's either failing for another reason, providing the power on the wrong lines or is just a poor quality PSU.

    How much power does it provide on the +12V line (combined if it's got multiple lines)? From a modern 550W PSU I'd expect at least 400W (33A) as that's the line that the power hungary parts of a modern system mostly use. Something like the very popular 520W Corsair ]HX-520 provides 480W (40A) on the +12v line, which is the same as that AOpen 1000W PSU (that particular one wouldn't power four graphics cards, it's designed for other types of power draws).

    As for cheap PSUs, there's nothing enforcing standards unfortunately so the lesser reputable branders use all sorts of tricks to up the wattage like using peak power instead of sustained.

    If you don't believe me try the various power supply calculators out there, most of them will give you around a 400-450W rating, after a generous safety factor, and I'd be very surprised if any of them recommended a higher than 550W PSU.

    EDIT: Of course if you've overclocked the components up the wazoo and have an exotic cooling system you may actually be exceeding 550W, but I guess you're not running at 4Ghz+?

    i was gonna go for this ]http//ww…104 but it's way more than i need (or wanted to pay) but if you're happy spending that sort of cash this will run pretty much anything (its got 4 6+2 pci-e connectors), is modular and has got a 7 year warrranty.

    I guess i was just under the impression that because my 550watt psu was failing i thought i needed a much more powerful one, but if you guys are right, then these reputable makes, should do the trick.

    But, as im not a big fan of corsair, and have had trouble with a few of their products in the past, i think i may go for this: ebuyer.com/pro…047.

    What you guys think to power and future proof my system?

    Thanks and rep

    No, just 3.5 ;P

    The top tier of PSU manufacturers (in no particular order) are Enermax, and Antec(top range models), both produce their own power supplies and due to their fantastic quality build and stable volt lines have the best reputation. Next is Corsair and Tagan who have now been in the market for around ten years and have an excellent reputation that some class them as top tier manufacturers. In the second tier is OCZ and silverstone, and slightly below this is Hiper, Coolermaster, Zalman, and the newer manufacturer Be Quiet. Then we have Akasa and Maxpower (part of the Tagan Group). All are good quality PSUs, some slightly better than others but you get what you pay for!

    This is only a guildeline and subjective list, but will help you select a good quality power supply.

    Given how much power supplies from the same manufacturer vary I'm not sure ranking them in that way is very useful. For example based on Behardware's latest ]returns report Coolermaster is excellent in general and produces the least returned power supply in the 500-550W range but also makes the 6th most returned power supply overall.

    I looked at a couple of reviews and it seems to get some decent comments so it should be fine.

    Ranking the power supply units was only a guideline to help suggest which was probably the best power supply units available. Further research is always needed when investigating which component that are appropriate for the users requirements, though recommending what are the best manufacturers in the industry or market can help avoid most some pitfalls or problems. The main reason is those brands have acquired a following due to their build quality (components, internal electronics etc) after sales and services (technical support and guarantees), value for money, and other factors (rail stability, noise, expansion, future proofing, history, etc).

    Concerning Coolermaster for example whilst the company have improved over the years, their build quality and rail stability varies from power supply to power supply, unlike Antec and Enermax for example where the voltage tolerance is well within the acceptable levels on all their PSU's. That is part of a difference between a top quality and an good manufacturers. Past and present reviews can be easily found to back this up. Yes returns does provide a helpful guideline for identifying which component is reliable, but other factors described above is the reason why the professional or enthusiasts choose one manufacturer over the other.

    Yes, but I think your ranking is far too fussy; unless you're just rating the top range for each manufacturer they're too variable for average standings to mean anything.
