Hi, I currently have a areocool intergrator 500w with a gtx 1060 6gb and i5 8400

Is this a good enough gpu for higher end graphics cards?

Will it be able to handle any of the new RTX graphics cards?



Also it says this on the side of the psu what does this mean?

Dc output +3.3V +5V +12V -12V +5Vsb

Max current 18A 16A 38A 0.3A 2.5A

Max combined 110W 456W 3.6W 12.5W

It says this on the side of the psu what does this all mean?

Watts = Amps x Volts
Watts / Volts = AMPS
the DC Voltage output is fairly self explanatory.
max current is the Amperage for each voltage level or rail. the 3.3V rail, the 5V rail, the 12V rail, etc
max combined is the the answer to the equation W=VA and is the wattage each voltage rail can sustain.
the important one is the 12V rail, that is the true wattage of the PSU, cheaper units will put all the wattage on the minor rails (3.3v and 5v) your PSU is 456 Watts.

the video card will eat the most power and it only eats 12V, if the PSU has all the power on the 5V, the GPU will get no power.
knowing how much wattage each rail can sustain is important for your needs. if you are running a machine with 127 USB ports you want as much power on...

knowing how much wattage each rail can sustain is important for your needs. if you are running a machine with 127 USB ports you want as much power on the 5v rail as you can get and just enough 12V to get by.
if you are running a gaming machine the 3.3 and 5v are almost useless.

a quality PSU will rate the wattage on the 12V rail alone. an example:

649.2W on 12V the PSU is rated 650W

Sort of. Modern PSUs using DC to DC tech to power the minor rails will show ~99%+ of the output available on the 12V rail like you linked. But there are still many quality older units that use group regulation. They will have an output similar to what the OP linked. But just because it does, or doesn't show, 99%+ output on the 12V rail doesn't mean it's a quality unit. It's just an indication of what's inside the PSU. For example, here is a recent review from Jonnyguru.

Notice this PSU can do 648W of it's 650W on the 12V rail. Quality? Turn to page 4.

But that's not why I'm bringing this up. This was my second sample. The first sample did this too... to the tune of 300mV. It was also out of spec most of the time on the standby rail, something this unit didn't have an issue with. Efficiency at the time was atrocious, ruling out newer designs that could have produced this effect in order to comply with some of Intel's latest low load efficiency demands.

The second unit showed the same flaw, but only to 35mV, not part killing 300mV. Quality is who made it and their track record. I'd rather take an older group regulated PSU from Seasonic than a newer PSU like this that seems to have issues here and there. (And bad/suspect secondary caps.)
