    Need a PSU

    Just slapped my new rig together on a borrowed PSU. Put it through a monitor and it's drawing ~120Watts.

    Spec is: Asus P5Q-EM, Intel E6300, 4Gb RAM, 2 x SATA HDDs, DVD burner, PCI TV Tuner.

    I was thinking of getting a Corsair but I've also heard good things about Enermax PSUs from a mate.

    What are the thoughts on these 2:

    • 400W Enermax LibertyECO PSU, 86% Efficiency, 2x PCI-E 6+2P, 5xSATA, 2x12V 32A, PeakPower 440W @ £58.39 inc

    • 450W Corsair CMPSU-450HXUK, Modular, Sli, ATX, EPS12V PS/2, 20/24 pin, 5 year Warranty @ £58.64 inc


    Cheers.

    Re: Need a PSU

    What GPU are you planning on using? That might have a big impact on the PSU you need.

    Of the two you list I would go for the Corsair one, if only for it's modular nature.

    Re: Need a PSU

    Hi - I'm only planning on using the onboard gfx.

    I don't mind spending more on the PSU to get a more efficient one though as ultimately I'll save on power costs.....

    Re: Need a PSU

    You'll need to hit 50% rated consumption to get the peak efficiency. Having said that the drop in efficiencey vs load is probably equivelent between PSUs.

    What the wattage at peak power and idle?

    Re: Need a PSU

    Oooh - just worked out the efficiency difference and it'd take ~7.5 years for a more efficient one to pay back. Will probably have a new rig by then. That OCZ looks like the boy then.

    Thanks all.

    It's probably a bit late but yeah, I'd also say that OCZ.

    Re: Need a PSU

    Too late - have got the 400 now - running nicely though. Going to put a power monitor on it later but from memory I think it was running about ~120Watts so glad i didn't get a more expensive one.
