can I keep my 600 watt power supply with this

i5 3450
4gb 1066 ddr3 (2)=8gb
amd r9 280x
Intel dh61bf motherboard
1 hdd
dvd drive
2 led fans
all with a 600 watt coolmax psu with 3 12 volt rails with 51 amps total using a 6 pin and a 2 4 pin molex to 8 pin adapter

an online psu calculator says that i need a minimum of 399 and a max of 449, but thats with everything at max utilization. However It is somewhat of a cheap psu, and wile I plan to upgrade it whenever I get some spare cash; is it possible to run the 280x with it, as it is the new part in my computer that I'm not sure about.

  1. Coolmax? You could run the 280x with it but it would be kind of risky in my opinion.
  2. Best answer
    Coolmax PSUs are bottom quality. Not recommended at all, for anything. If that power supply blows, you run the risk of damaging your components. Technically yes, it has the juice to run your equipment, but I wouldn't recommend it. Get yourself a better quality power supply from Seasonic, Antec, Corsair, etc. Protect your components.
  3. A 600w Coolmax power supply does not supply 51 amps on the 12v rail. Only high end units supply all their power on the 12v rail and Coolmax is in the junk tier. Even if it was a high end unit 12 x 51 = 612 and not a single unit on the market is under labeled.

    Power supply tier list. Hint, start in tier 5 to find Coolmax.

    If you have this unit it supplies 450 watts on the 12v rail. 450 / 12 = 37.5 amps. The individual rails are not additive.

    I knew they weren't the best when I bought it, but that was when I only needed juice for a gtx 650 ti, and it was only $45 at the time at Frys Electronics so I was a good deal, and hopefully next month I will have the spare cash to get a better psu there is an Antec 600 silver rated psu for $80 at frys right now that I have my eyes on
  5. Best deal I see online for a high quality unit is this XFX. All XFX units are made by the best, Seasonic.

    $59 after a $10 rebate from NCIX.

    How about this seasonic 650 watt psu

  7. It's an older unit but it's a Seasonic so it will be a good one. It's cheap.
