    At $10 it makes sense as a backup PSU for troubleshooting or if your main PSU dies, but yeah, at $25, I'd still probably suggest people use a rebate and get a CX/m, the only advantage this thing has is +1 connector over the CX450 (Is there a reason for 1 6+2 on the CX? It makes some 1070/Tis unusable, which kinda sucks...
    Just some nerd from 'Straya

    Yeah and why bash the EVGA B3?

    I don't think you've been paying attention; EVGA's MO recently has been selling units way under cost and flooding the market with as many SKUs as possible.



    Likewise, If you think $25 is making a profit on any half decent PSU then you're insane.

    The B3 actually blew during testing; also cost-relative, for $25 I'm not going to expect good protections but at the B3's price point I'd expect it not to blow at least. The 450BT didn't blow during the testing.

    [QUOTE=Tator Tot;149633]In the US it's a different story. As I said, price is too close to a unit like the CX450.




    Yes I know it, but here it is usually half the price of the corsair unit.

    I guess you wouldn't be installing a high-end overclockeable GTX 1070 ti on that anyway, and I think they come with molex to 6/8 pin adapters on the box

    Alright lets do the numbers:

    30A Rectifiers, this unit uses 5, on Mouser you get each for 0.25$ when buying over 10.000 units. 1.25$ total.

    The main switches and pfc switches? There are 4 total, each IPA50R280CE costs 0.68$ in a 500 unit package (very small). so 2.72$.

    Bridge rectifier: 0.54$.

    X caps and 4 y caps: 1.6$

    Primary filter cap, 2$.(And this one is a United chemi-con, I don't see teapos on mouser)

    Bunch of SMD resistors and caps, you get hundreds of those for 1$, so lets just add 1$. xd

    Secondary caps, 0.183$ for each 2200 uF 16V nichicon (again no teapos appea on mouser), this unit has 3, so 0.549$.

    The rest of the secondary caps(7) (are 1000 uF or lower (some with rated voltages under 16v), 0.111$ for each 1000 uF 16V cap, so 0.777$.

    Fa4800: 0.564$

    We are at less than 12$ total. The rest would be the casing, the fan, remaining ICS, the transformer, coils, relay, wiring, the pcb and assembly cost. Might be insane but I see plenty of margin there.

    And this is buying parts from an US supplier, the oem likely has direct contact with the manufacturers.

    So its worse when the PSU blows up under a fault situation than when it kills the rest of the PC??

    Are you implying that the 450 bt could kill a pc?

    Don't dismiss the cost of those components. Likewise, you need to keep in mind that SuperFlower will need to pay the contractor who built the unit, and also make a profit themselves.
