Can my PSU handle newer GPU's?

[Orazz]

I have a 4yr old pre-built computer from IBP. The rig is as follows:

i7 930 (1366 LGA) @ 2.8 Ghz [not OC'd]
Asus P6t SE Mobo (x58 chipset)
3x2GB DD3 Ram
Asus Radeon HD 5770 GPU
XION PowerReal XON-700P14N 700W ATX12V / EPS12V SLI Power Supply

I am looking to upgrade my gpu to handle upcoming games such as GTA V when it comes to PC. The problem is that my PSU only has 2x6pin connectors whereas many newer GPU's require 8pin or 6 AND 8pin connectors. I am trying to avoid upgrading my PSU and RAM at the moment, but plan to do so in about a year, possibly less.

Question: Can my PSU be safely used with cards like the Geforce 670 which require 6pin+8pin? I could maybe go 6pin to 6pin and then use an adapter for 6pin to 8pin?

Question:Is the 760 a better option? The asus one im looking at requires just an 8pin connector so I could go 2x6pin to 1x8pin adapter? Dangerous? Doable?

I'm concerned that my PSU may not handle the load and I don't understand all the intricacies regarding continuous wattage/volts, 12V rails on my mobo, etc.

I appreciate any help, suggestions. Looking to take advantage of Black Friday/Cyber Monday sales!

Reviews - Xion PowerReal 700W
considering that you have it for quite some time now and that your cpu can really benefit from overclocking, i would suggest an upgrade.! is there a budget you have?

As above, worth upgrading regardless.

A 760 is a good upgrade but its been around a while now and uses the old GK104. May be worth waiting for the GTX 960.

I hear you and I know my immediate plan is not the best approach per se but I figure I need at least 450/500$ for new GPU, PSU and ram. I can only spend about 250$ at the moment so I was hoping I just get a GPU for now. I don't think I'll be at the point of affording a 970 any time soon...

Is the bigger risk that my PSU is older or that it won't, based on its stats, handle the continuous power output (could die) that newer cards require? I'm not knowledgeable when it comes to doing the math required in calculating the output all my computer components require. Would my originally listed adapter ideas work?

Another draw back is I have a mid sized rig so physical size of components is a consideration and my mobo (P6t Se) is the smaller version of the card...basically I don't have a huge amount of room in my case. I can't afford a new rig so I'm trying to make this one work.

It may be fine as its been fine for so long, but its not a good quality unit.

you can run 2x6pin power pcie cables through adapter to 1x8pin . 2x75w(6pin) = 150w(8pin) however as you cannot prevent electrolytic capacitors from aging, still not recommended. for a gpu upgrade i would suggest though an r9 280, as it offers better performance and has a better price, than gtx 760 if you have a midi atx tower would still do just fine!

Figured as much. I appreciate everyone's input.
