[SOLVED] How big is the power supply on a dell optiplex 790 with a i5 2400 in it?????

[cmangorham]

I was going to upgrade this system im going to buy of ebay and I want to know the power supply wattage because im going to get a strix rx 560 of ebay for 90 bucks and get a molex to 6 pin power connector. Im going to get a strix because i have heard of problemes with dell optiplexes and rx 560s that draw all there power from the pcie thanks

It should be noted on a sticker on the side of the power supply, but I'd advise upgrading that either way.
