Hey all, here is the system that I'm working with:

Quad-Core Q9550
GeForce GTX 260
4GB G-Skill 1066
Creative X-Fi
Western Digital 250GB
4 Case Fans

Will this power supply be enough for safe play?

Actually, I'm reading all the reviews and some of them are pretty scary. What would you recommend in terms of safety? I'm sort of tight on funds, but would rather my gear not be put at risk.

Don't do it! If "max" is part of the name of the PSU, it is either a reference to the number of components it will take with it when it dies, or the extravagance of the pyrotechnic display.
Something like an Antec Earthwatts 650 would be good, or something from Corsair, Seasonic, or PC Power & Cooling.

Sorry there was a delay between writing and posting (I'm at work). My reference was to your OP. What is the PSU requirement given for your graphics card?

Oh, btw unless you are planning on an extreme overclock, get DDR2-800 that will operate at its advertised timings on the JEDEC standard 1.8V.

Enermax could well be the exception that proves the rule. They are also generally well-reviewed, especially their latest models.
Sites that do quality, competent technical reviews of PSUs (including load testing, waveform analysis, etc) include,,, and All use high-end equipment for load testing. Jonnyguru and Hardwaresecrets also disect them to tell you Why they got the results they did.

Hey peoples,

I am getting a new psu after losing my last one to a storm.Heres my system:

AMD Phenom II 940 black edition 3ghz quad core
Asrock K10N780SLIX3
4Gb Crucial Ballistix RAM
320gb western digital hdd
Nvidia GTX 260

I also have 6 fans, a fan controller ,a couple of dvd drives and neon lighting. Can anyone recommend a decent psu for me. I am trying to be on a budget of about $450 but a bit over is fine. Thanks

Here is a link to a power supply calculator:

Fill in the blanks as best you can to come up with a rough estimate of power requirements for your particular configuration. Please bear in mind the results will be overestimated because there are a lot of cheap, low quality psu's of questionable reliability that people insist on buying.

Seasonic, Corsair, and PC Power & Cooling offer high quality power supplies that are very stable and reliable. They consistently earn high marks in technical reviews and comparisons. They're also the three brands most often recommended by veteran posters at this forum. My personal preference is Corsair.

I was going to say "Not Raidmax". But the rest of the regulars beat me to it. So never mind. :)
