    Default Upgrade time coming up

    So, I've been using Corsair CMPSU-450VX since 2009 but planning some upgrades. Such as first time using a GPU that requires more power than the PCI-e lanes provide.

    Currently have AMD FX 4300 (95w) and AMD Radeon 7750(55w), and 2 SSD and 1 WD green HD. IIRC kilowatt measured under 200w, and even at the UPS that included monitor, speakers, etc was still under 300. (measured under load)

    So first, with upgrading video card that uses 150+watts (AMD RX 480) What are thoughts on power supply?

    And thoughts on Corsair CX series, I know it seams to be hit or miss and it gets snubbed by those "in the know" but its rated well here, and they seam best value.(bought my wifes for ~$20 w/ rebate)

    450VX http://www.jonnyguru.com/modules.php...Story3&reid=64
    430CX http://www.jonnyguru.com/modules.php...tory4&reid=214

    Also planning on upgrading CPU/Mobo/Ram once Zen comes out, and as I pass my parts down the line, could do so with power supply as well. ( have raidmax/roswill/generic PSU's well over 10 years that receive near daily use)

    Why not the newer cx450m? It's much better than both.

    Like others have said.... Don't get the CX430. Get the CX450 instead.

    OH, I linked to the CX430 on this site only because it was only CX w/ a review here.(most review sites give it a "it's ok for being so cheap but would buy better") My understand was its a little bit less of a unit than the VX line.

    I was originally thinking the CX550, but I personally not seeing a reason why to go up, even though ALL online power things say I need 550-650 min...
    If I add all devices max watt it's under 180, which is well within a good 300w. I find odd as I have a power hungry CPU, 2xSSDs + 1xHD and a gaming graphics card. And simply gaming doesn't max that out alone.

    So I guess my question is 2 parts
    1. Watts, 450w really fine?
    2. Thoughts on the CX line from corsair? (modular is a non issue, easy enough to hide spare cables in empty bay)

    Just don't use calculators, easy enough. The CX450M is fine and a good PSU.

    The Corsair product lines get progressively better with each generation, so it makes sense to get the newest version. The x50W versions have been upgraded to DC to DC among other things.

    Here's Mask's review of it: http://www.jonnyguru.com/forums/showthread.php?t=13511

    The new versions are currently only available in the "M" version. If you can wait a few months, the non-M will also be available.

    Any reason for the aversion of CX430 vs CX450M?

    As I mentioned the Modularity is a non issue for me, and my watts max is under 50%.

    I measured again, and got 180's, 80% efficient PSU means ~144 watts. I've verified my kill-a-watt with light bulbs. And for load, I copied from network to an SSD, defraged the HD, while running l4d2 on top of the usual Firefox with 100's of tabs and a virtual box doing it's thing.

    I did have a question for the PSU MAX, is that max input or output? (I've always thought output) And with it's efficiency is output right?

    If our aim is to be close to keep most usage under ideal 50% load, wouldn't a 300watt PSU be better? on paper rounded up max was 178, but reality was 144(minus 20% PSU)
