HI Guys
I recently posted a thread PSU Not working after clicking sound: http://www.tomshardware.co.uk/forum/318777-10-working-clicking-sound#t2400566, it seems my PSU is dead so i need to purchase a new PSU

old PSU (not working/dead): Alpine 600W, :http://www.tekheads.co.uk/product/600Watt-PSU-120mm-Red-Fan-2x-SATA-Alpine-Retai-Boxed_36228.html

(2) Ace 650w PSU: http://www.ksn-online.co.uk/components-power-supply-unit-psu-ace-650w-black-psu-with-12cm-red-fan-pfc-p-10478.html

  1. Complete shite!
    You're going to have to spend some dosh mate!
    Instead of spending 15 quid on another unit that'll blow up.
    Spend @£40 on something that's reliable and carries a 3yr warranty.

  2. could you recommend a good psu?.....
  3. its recommended that you post full specs of your system.
    5770 isn't a demanding card , consumes under 100 W on full load.

    problem with second link is it doesn't like specs of PSU i.e. current on different voltage rails.
    P.S. i wouldn't recommend either of two because
    a) I'm not familiar with brands
    b) 14~20 pounds for 650W PSU? i have not heard of such
  4. Specs

    Packard bell Ixrtreme X5620 (M3720)

    Core 2 Quad Q8300 2.5GHz

    4GB RAM

    640GB WD Caviar Blue

    Broken/Dead 600w Alpine PSU

    motherbaord with Onboard Nvidia Geforce 7100 Graphics (Upgrading to XFX/ATI Radeon HD5770)
  5. any more suggestions for PSU's as i need a good PSU around £35-£40

  7. is this any good Evo Labs 650w Modular 80+
    http://www.airetechit.co.uk/e-shop/products.php?21574&livemode=1

    (1) 80+ efficient
    (2) independent Double 12v rails
    (3) Modular

    would you recommend this?
  8. Stick with brand names that have a 3yr warranty.
    Any one i suggested will power your specs just fine and are well-known and reviewed units.
    Cheap brands that boast 650W seldom can deliver a 350W continous load.
    I noticed the unit you link includes no details = red flag!
  9. Every PSU that wasn't linked by you in this thread will rn that HD 5770, if you low on cash you can get sometime like this CoolerMaster GX-450 80Plus Bronze PSU which supplies more power than the Corsair CX500V2 and has a 5 year warranty vs the (3)? of the CX500.

    in north america (could be different in the UK) the CX has a one year warranty and the CX v2 comes with a three year.

    frankly an antec earthwatt 380w would power a system with a 5770 with no issue

    some other budget series besides the earhtwatt and corsair CX

    antec neo eco
    antec HCG

    Thanks for suggestions on those two PSU I'll have a good look at them, also for that PSU I stated above i should use roughly

    95W core 2 Quad Q8300 95w=7.9A
    ATI HD5770 (100W)/108W=9.0A
    others: (Motherboard, RAM, Hard drive etc) 3-4A

    Total=19.9A/20.9A

    Graphics card 9.0A
    95w core 2 Quad Q8300 7.9A =16.9 on one 18A Rail (1st Rail=1.1A spare)

    others: (Motherboard, RAM, Hard drive etc) use 3.0-4.0A one 18A Rail (2nd Rail=14-15A spare)


    1st Rail= 18A
    2nd Rail=18A
    Total (each) 18A= Shared 36A


    this is what i worked out (roughly)

    Even though with your system you should be around 250w during gaming, it's doubtful the PSU you linked can provide stable power on it's 12v rail. I doubt that unit can provide 300-400w power. A solid 650w PSU will provide 50a+ on its 12v rail. On that unit, the 12v rail (its one rail with a split) is highly underpowered which is a dead give away of a bad (and dangerous )PSU. here are some articles that may help you.

    difference between three units with the same "stated" power

    @ dirtyferret thanks for the links

    im quite new to working out PSU specs such as 12A Rails ect, but i think im now getting the hang of working out all this stuff :D also those links you provided are really useful & also get that cheaper psu's wont always supply the full 600watts such as a proper quality PSU maybe 400watts or so

    the reason im quite new to working out PSU specs is because i just had normal desktops and didn't have to consider the Power requirements for Graphics cards ect :)

    thanks
  15. What about this PSU: Coolermaster eXtreme Power Plus 500W

    http://www.coolermaster.com/product.php?product_id=3738

    http://www.ebay.co.uk/itm/NEW-ATX-COOLERMASTER-EXTREME-POWER-500W-SATA-PCI-E-PSU-/260846296832?pt=UK_Computing_PowerSupplies_EH&hash=item3cbba69f00#ht_3235wt_1002

    (1) only £35.00
    (2) 70% efficiency at full load (not quite 80% efficency/80+ but its pretty good 70%?)
    (3) Good brand name of Coolermaster
    (4) Two year warranty
    (5) As its a good brand should deliver full 500 watts
    (6) also states: With a life-time of 100,000 hours and protection for OVP/OCP/OPP/SCP, these power units are made to last

    is this a good PSU to power XFX/ATI Radeon HD5770?

  17. you won't get a good PSU under the price of the antec i linked, including that CM 500w for $35 and 70% efficiency is rather bad. Also, CM makes plenty of crap along with their decent PSU.

    if you simply want to but a cheap junk PSU then go ahead, it's your PC
  18. Hey i know CoolerMaster may not be the best when it comes to Manafacturing best quality PSU's But why are they a Crap brand, they make good cases e.g. HAF X & also make some very good case fans

    what makes you say its junk?, anyway i think i know all i need to buy a good psu ;)
  19. here is a review of that PSU, it becomes out of ATX spec after 80% load

    http://www.hardwaresecrets.com/article/Cooler-Master-eXtreme-Power-Plus-500-W-Power-Supply-Review/728/10
  20. ok thanks for the link now i understand why not to buy that psu :)
