Computer has been shutting down randomly while playing BF4, i assume my PSU is the culprit, however it never did this up until a few weeks ago. Anyways, dont have a lot of cash on hand right now so i need a cheaper but good quality 650+ PSU that has 2 8pin PCI pins and 2 6 pins or just 4 8pins. (each 760 has a 6 and 6+2 (8) pin)

Specs:
i7-4770k OC 4.4Ghz
2 760's in SLI
2x4GB 1600mhz
128gb SSD
2TB and 750gb 7200RPM HDD
H80
Shit ton of fans.
RAIDMAX RX-735AP PSU*****

appreciate the help, ive never been big on PSU's (obviously) and am not sure what one are of decent quality and whatnot.

NOTE: the calculators say i need a 560w psu. but with the OC and my bay fan controller im sayin 600w minimum

I'm surprised the calc only said a 560W. Are you sure you specified SLI and 2 x GTX 760? A 650W PSU will be minimal for those two cards in my estimation. I'd rather see a 750W good quality unit for some overhead. Here are some 750W units. 650W are hard to find with 4 x 6/8 pin cables, because they are usually not intended for that kind of +12V load.

These are the brands I've come to trust from personal use. I'll leave it up to you to verify the PSUs have the necessary 6/8 pin you need. The first Corsair in the list is out.

You've got a Chokemax, so yes most likely your PSU isn't able to hold up its end of the log.
About the cheapest I've found you might consider is this FSP-built EVGA: http://www.newegg.com/Product/Product.aspx?Item=N82E168... for $88 shipped.
The few I saw that were cheaper were built by CWT, which is fast developing a reputation for using substandard parts, like capacitors that can't take heat.
I believe a much better choice, for $93 shipped, would be this Rosewill Capstone: http://www.newegg.com/Product/Product.aspx?Item=N82E168... which is built by Super Flower, one of very few companies in Seasonic's league.

That system when overclocked will only pull around 550-575w, so the wattage of your power supply is sufficient. The problem is RAIDMAX is a crappy brand that puts out very poor quality power supplies. The reason it would have been fine before but not anymore is that it degrades MUCH faster than quality brands.

This Antec would be perfect for you:
