    Default Cheapest PSU which will not damage hardware

    What is the cheapest PSU I can buy which will definitely not damage my hardware or start a fire?
    I have been lurking on PSU forums for a while, but I've never seen that question asked (apologies if I've missed it).
    The answer will obviously depend on the power requirements of my system - so I would appreciate suggestions for 400W, 500W, 600W

    Corsair Builder Series
    Rosewill Green Series
    FSP Vital Series
    Silverstone Strider Essential Series
    Antec Basiq Series
    BeQuiet System Power
    CoolerMaster GX Lite Series
    Enermax Triathlor
    Enermax NAXN ADV
    Fractal Design Integra R2
    Thermaltake Smart Series

    There's most likely some more lines that I'm forgetting, but at the end of the day, you're still going to be paying around $40-80 for a decent PSU in those wattage classes.

    If you're in the US and are patient you can often find Corsair's CX430 on sale for ~20, or for $40 with a $20 mail in rebate card.

    I second Tator Tot's list, also. I can't think of any others that I'd recommend.

    The cool thing about the Corsair CX lineup is they offer modular versions for just a little bit more. I'd seriously consider that - once you go modular, you'll never go back...if you can help it! Good luck!

    Well, anything that's insanely cheap (say like $20) without a rebate is pretty much always trash. Then again, trash has been sold at premium prices (I know, I bought a couple, although that was many years ago). Luckily, most PSU brands today have learned to use good OEMs for their products.

    Rig 1: Core i5 6600K - Asus Z170 Pro Gaming - Corsair Vengeance 16GB PC2666 RAM - MSI GeForce GTX1070 - Samsung EVO 850 500GB SSD + 2TB Seagate SSHD - Corsair RM550x - Fractal Design R5 - Win10 64

    Rig 2: Ryzen 1700X @ 3.9 GHz - Gigabyte X370 Gaming 5 - Corsair LPX 16GB PC3200 RAM - Gigabyte GeForce 1070 - 250GB Samsung EVO 850 SSD - Corsair RM650i - Win10 64
    HTPC: AMD A6-6400k - MSI FM2-A75IA-E53 mITX - 8GB Kingston HyperX 1866MHz - 3.5TB storage - Silver Power 460W passive - CM Elite 120

    I'm actually based in UK, but I think I should be able to get most models here.

    I'm a bit surprised that so many people are recommending Corsair CX PSU's, I'd got the impression that quality was thought to be not so good of late.

    It seems to me that you want a PSU with a long life, but actually it's more important that your MB etc is protected in the event of the PSU failing. Is there some kind of circuitry which I should be looking for?

    Pshaw! I try to "right size" PSUs these days, and have surprisingly few cables left over (if any).

    I scored some Enhance 500W PSUs from Geeks for... I want to say... $14 shipped per unit.

    But yeah, generally speaking you are right.

    Nothing branded "Enermax" is cheap . LEPA uses the same layouts and they are way cheaper.
    I'd add also the XFX Core Edition and Super Flower Amazon.

    Not strictly true, ENP450AGT is quite decently priced, about on par with CX430.

    Triathlor units are also quite reasonably priced vs what they offer (I have 550W one now)

    Ok, so maybe it depends on where you are. Here in Germany, NAXN are hardly available and a 300 W Triathlor costs about as much as a 450 W XFX Core (V2, though) or Corsair CX430.
