    Try this one:
    http://www.amazon.co.uk/Corsair-CMPSU-500CXV2UK-Builder-Series-CX500V2/dp/B005851O16/ref=sr_1_26?s=computers&ie=UTF8&qid=1333974124&sr=1-26
    or at least get a "good" name brand - Antec - corsair - OCZ -etc. (at least it you want to keep your friend). :)
  2. CX series is made by CWT.it may not be the worst but i am sure it's not the best.seasonic is definitely far better than CWT.the one i listed is rebranded seasonic unit by xfx.and for 40,it's a good deal.

    Im considering the XFX now but these are cheaper and are they as good
    OCZ CorexStream 500w £31 OCZ StealthXStream 2 £37 Coolermaster GX Lite £39

    The OCZ CorexStream 500w has a combined 45 Amps on it's 12v rails which isn't bad. (2 - 12v rails)
    The OCZ StealthXStream 2 (500w) has 36 Amps. (2 - 12v rails)
    The Coolermaster GX Lite (500w) has 36 Amps. (1 -12v rail)
    You'll find that the Amps are what's important. Multiple rails are also a plus.

    i have the 600w version of this and it’s a good psu no problems and modular cabling to.

    So is the XFX as good as the two OCZ's because they are a lil bit cheaper.

    The XFX has a single rail with 34 Amps. (1-12v rail)
    Like I stated the Amps are whats important and multiple rails are usually better. Seasonic like OCZ is a "good" name PSU and if it made the XFX I imagine the quality would be good. Specification wise I'd prefer the higher Amps/Rails of the OCZ's.

    I would hope CWT is not THAT bad, Corsair uses those for the higher end HX power supplies as well.
    Many of the OCZ's are FSP based, some people do not like FSP, but i have never had a problem with them.

    It is hard to have 45 amps @ 12 volts on a 500 watt power supply... very good catch Delluser1.

    45*12=540

    So is the Stealth better than the Core as the Stealth is coming tommorow and I could easily trade it for rhe XFX or Core.
  16. From what i see, they are within 1 amp(12 watts) of one another.

    That said, ebuyer is listing the CoreXtreme as a 45 amp unit. so that is why you had some misinformation.

    The XFX is lower, but expected for a 450 watt unit.

    But the XFX is probably better quality though as it it as rebranded Seasonic and a Seasonic in build 3 and it has been the most reliable psu. The OCZ Core I still don't know about as its not 80+ and I cannot find anything on it and the XFX shouldmbe fine for the build as 450w is probably perfect for the gtx550ti
  18. With hardwarecanucks.com having your card with a faster cpu they only pulled 262(anand got to 275) watts. So yeah, i think you are good :)

    ....and yes Seasonic power supplies ARE better then FSP(i almost guess that anything in the ...Xtreme line are FSP based units.)

    Either way, I personally have had good luck with BOTH companies power supplies in the past.

    The XFX looks to have 34 Amps(408watts).

    It is hard to find info on both units. Many power supplies go under a slightly different number in different parts of the world. Just adds confusion for nothing.
