Hi guys, recently my old P55 motherboard died so I decided to purchase a haswell build. I bought an Asus Z87-pro and an i5-4670k.

My current PSU is an OCZ Modxstream Pro 700w, and I've heard they have a reputation for crapping out after 3-4 years (bought it about 3 years ago). My concern is that am I risking my new motherboard by hooking it up to this PSU incase it decides to short out? I'd hate for these parts to fry because I didn't want to spend the extra cash on a new PSU as well.

I don't know if I need a 700w PSU, I'm not planning on running SLI GPUs, but I do plan on lightly overclocking my CPU.

Thanks for the suggestions.

Btw, if I were to replace my PSU does anyone have any suggestions?

The GeForce GTX 770 consumes the most power out of the three card models you've listed.

For a system using a single GeForce GTX 770 graphics card NVIDIA specifies a minimum of a 600 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 42 Amps or greater and that has at least one 6-pin and one 8-pin PCI Express supplementary power connectors.

XFX P1-750X-XXB9 750W
• OEM: Seasonic
• maximum combined +12 Volt continuous current rating of 62 Amps
• four (6+2)-pin PCI Express supplementary power connectors
• 80 PLUS BRONZE Certification
• 5 Year Limited Warranty

It's currently cheaper than the 650 Watt version.

Am I going to be ok if I use my current power supply for the time being, and just get a new PSU with a new graphics card later on? Or am I pushing my luck with this OCZ? I just don't want to fry my new components..

You should be fine for now since you're not overly stressing that PSU.
