A question to forum experts Smiley
I have the following hardware

1x Sentey SDP850-SS 850w http://www.overclockear.com/images/upload/reviews/Sentey%20SDP850-SS%2014.jpg
3x ati 5870
1x intel i3 2120 (tdp 65w)
1x MSI Z77 g43 http://www.msi.com/product/mb/Z77A-G43.html
1x HDD 320gb
1x 2gb ram stick
1x USB wifi

2 5870 will be powered tru pcie cables and the third shoud be powered using molex to pcie cable.


Can the psu stand my Hardware? PSU engine says it will be enough 700w but that sounds wrong.

You should be fine, but I would not add anymore.
I have 3x HD 6970 running overclocked fine on a PCP&C 950w.
5870 power consumption is about the same.
