    PSU Recommendation

    Well my 480W Thermaltake PSU emits a nice high pitch noise. Thats without the PC on. In fact it won't even turn on. So I guess its dead. So I need a new one. I would like a modular one and quiet. As for power usage, it is powering an Intel E6600, 4GB RAM and an ATI 4770. 1 SATA Hard drive and a DVDRW. So nothing fancy. However I would like it to cope should I go for an i7 build and a slightly better graphics, although I can't say I would opt for anything more than 'mid range' whatever that is at the time.

    So fire away your suggestions.

    Re: PSU Recommendation

    I got a seasonic 750-x, there is a 650w model as well which will be more than enough, even with the potential upgrades.

    It modular and really quiet.

    I'd stretch to £100.

    Catch is though Amazon has to stock it. I have vouchers to part pay for it!

    Re: PSU Recommendation

    A decent 450w psu is all you should need (ps did you have a thermaltake TR2 ?? if so it was not a very good psu)
    For up grade potential depends on what you class as "mid range" graphics

    If Amazon only.
    http://www.amazon.co.uk/OCZ-600W-Mod...0160750&sr=1-3

    http://www.amazon.co.uk/OCZ-500W-Ste...0160750&sr=1-2

    http://www.amazon.co.uk/Cooler-Maste...0160809&sr=1-2

    Or a corsair http://www.amazon.co.uk/gp/search/re...rnid=365489011 (although they are not cheap on amazon)

    Antec truepower new http://www.amazon.co.uk/Antec-TruePo...161581&sr=1-15
    These are semi-modular, ie not all cables are modular, made by seasonic and have 5 year warranties

    Re: PSU Recommendation

    This would do the job for the current setup the OP has:

    http://www.amazon.co.uk/Seasonic-S12...0163216&sr=1-3

    The PSU even has a pair of 6 pin PCI-E power connectors.

    If the OP wants a PSU which has more power then one of the following should do the job:

    http://www.amazon.co.uk/Corsair-Powe...0163351&sr=1-1

    http://www.amazon.co.uk/Corsair-Powe...0163351&sr=1-2

    Re: PSU Recommendation

    Stringent is willing to spend £100.00 for a modular power supply with room for future upgrades. Where are some of these recommendations coming from?

    Cheers

    Re: PSU Recommendation

    There is very limited choice from Amazon itself for modular PSUs unless the OP goes with a private seller. TBH,I would stick with Amazon itself as it should be better for warranty purposes.

    The OCZ ModXStreams are OK but tend to cheapo capacitors.

    The Coolermaster Silent Pro range tends to be better. It seems from the reviews that they use Japanese capacitors(Nippon Chemi-Con) in the primary and Taiwanese capacitors(Teapo) in the secondary.

    One of these units are worth looking at:

    http://www.amazon.co.uk/Coolermaster...168439&sr=1-11

    http://www.amazon.co.uk/Cooler-Maste...168439&sr=1-16

    http://www.amazon.co.uk/Coolermaster...168439&sr=1-18

    The reviews seem positive. Hardware Secrets and Jonnyguru seem to rate the 600W version quite well. The 500W and 700W versions seem to get favourable reviews as well.

    Re: PSU Recommendation

    Hmm I am a bit dubious about private sellers. I have a Corsair Modular 620W in my work PC and its ace. I would like modular though. I had forgotten all about Coolermaster, tend to associate them with just fans. Hehe. The old PSU I had is a Thermaltake Purepower (Pure Power-480APD). It kinda did the job.

    I'll keep those options in mind, but I'll release you from the Amazon tide, which would be the one to go for then? I am thinking either Corsair again or Be Quiet?

    Mid range graphics would be about the £150 price tag.

    Re: PSU Recommendation

    I would look at one of these Antec PSUs:

    http://www.scan.co.uk/Products/650W-...-80plus-Bronze

    http://www.scan.co.uk/Products/750W-...-80plus-Bronze

    Both are made by Seasonic AFAIK and have got good reviews.

    There is also the Seasonic made Corsair HX650W:

    http://www.scan.co.uk/Products/650W-...-Certification

    The PSUs have 4 PCI-E power connectors which will be useful for a dual graphics card setup.

    OTH, if you intend to run one card only then one of the following Seasonic made units are worth looking at:

    http://www.scan.co.uk/Products/450W-...-year-Warranty

    http://www.scan.co.uk/Products/520W-...-M-B-connector

    Well that's strange seeing as the current ModXStream's use Teapo capacitors on both primary and secondary and Teapo are the one Taiwanese brand that is currently rated as good as japanese capacitors.

    http://www.hardwaresecrets.com/article/936/4

    It is a bit weaker than the coolermaster slient Pro, however it can supply it's stated load, just not higher than the stated max wattage, the cm can take more than it's max spec which is one reason the cm is rated higher.

    The 500W ModXStream uses "Trec" brand capacitors in both the primary and secondary:

    http://www.bit-tech.net/hardware/psu...w-psu-review/4

    The same capacitors are seen in the primary with the 700W version:

    http://www.hardocp.com/article/2008/...power_supply/3

    If the ModXStreams now use Teapo capacitors this would be an improvement as I have no idea about "Trec" capacitors.

    Also Teapo capacitors for the primary seems more of an economy measure.

    You can probably get away with cheaper capacitors in the secondary.

    All of the industrial PSUs I have seen only have Hitachi,Panasonic,Rubycon or Nippon-Chemicon primary capacitors(these are Japanese companies). Skimping on the primary capacitors is not necessarily a good move. The same goes for the voltage regulation sections of many motherboards(including those of many OEM motherboards I have seen) which also tend to use capacitors from Japanese companies for such critical parts.

    Re: PSU Recommendation

    That's the old one based off the FSP epsilon design, heat sinks are a give away, this is the new one http://www.hardwaresecrets.com/article/936/2


    Also capacitors are not the be all and end all, as has been seen before, let me see if I can find the review

    PS thoes are the standard heatsinks used by CWT

    EDITl: Damb I cannot find it now, there was a review of one of these flashy, unknown make psu's it made a big thing of "all japanese capacitors" on the box, and while it did indeed use all japanese capacitors, the transient filtering and Rectifiers where a joke, which ended up with some hidious noise one the rails, voltages getting close to min ATX specs and the slightest power surge would of killed it and fed through onto the rails.

    So basically you don't know if you are getting an old or new version of the ModXStream. At least Antec add "new" to their latest designs. It does not really instil any confidence TBH!

    Like the fact that "Trec" brand capacitors are still being used,right??

    Also modd1uk knows someones who works for a company who distributes OCZ PSUs and it seems that there have been some issues.

    If industrial and OEM components use Japanese capacitors for critical parts (these are NOT marketing driven decisions BTW) then I think they are a safer choice. Even the industrial mini ITX motherboard I got recently only seems to use Japanese made capacitors. Again this is not a marketing driven decision. This ties in what I have seen in other non-computer areas too.

    Well of course the basic design has to be good enough in the first place!! An EZCool with capacitors made of unobtainium is still an EZCool!

    The fact is that it is the long term reliability of using cheaper components which is the main sticking point IMHO. A good design with cheaper components will tend to have more issues in the long term than a good design using decent components.

    If companies are using Japanese made capacitors in their OEM and industrial motherboards and PSUs for critical parts then this is a choice dictated more by reliability than anything else.

    Anyway this is my viewpoint and I am sorry to the OP if I derailed the thread.

    Re: PSU Recommendation

    Stringent, if you're still looking..

    http://www.scan.co.uk/Products/625W-...EE-TWISTER-FAN

    This is a brilliant PSU, mine's utterly silent and it have 4x 8pin PCI-E's on it.. and the 88% efficiency is just amazing.

    Or there is the 525w version, for the same price I paid for the 625 2 months ago..
