I just bought the FSP HEXA+ 500w.

Motherboard = Z170A Pro Carbon MSI
CPU = I5 6600K
RAM = Corsair LPX vengeance 16gb
GPU = GTX 1070.
CPU cooler = NOCTU U-14S CPU cooler.

I currently don't have the 1070 (I have been saving up money), and I have been running on that PSU for 3 days straight downloading from steam and playing some of the games downloaded (with fans maxed out including the CPU cooler, to test the PSU). I am now getting my graphics card in 6 days. Will I have any overclocking limits on that PSU? Should I try overclocking my CPU right now?



Thanks for all help!!

I'd suggest if you plan on keeping that psu, leave your system at stock clocks and shy away from anything that's seriously cpu / gpu intensive enough to go past 50% usage on both

given the review of the 400w version it is a budget psu

no overclocking of any kind



save for a good 520w or better psu from seasonic, antec, evga, or xfx before getting the 1070

This is the one, right?

That's a kinda sketch power supply for the components you'd be powering with it. You have two weaker 12v rails at 18A each, which is something you'd typically find in a low end 450W power supply, not 500W. My Antec VP450, which cost $35, has the same 12v rail set up. You'll have to be pretty damn careful balancing the load between both 12v rails, because during the momentary power draw peaks, you'll be pulling pretty much spot on the maximum power this PSU can supply through the 12v rails. Even without looking closer into the specs and what components go inside this power supply, I can tell you, it's probably pretty garbage.

I wouldn't overclock on that PSU. I'd be afraid to run a GTX 1070 on it, let alone overclock on it. Remember that overclocking draws exponentially more power the faster you push clock speeds. I'd say return that thing ASAP before anything does go wrong, and find a higher quality unit. Refer to this here list and pick out a PSU within the 550-650W range. If you can find a steal on a good 750W unit, sure why not. My recommendation would be something on that tier list that's got a solid single 12v rail. Dual rails get kinda fishy sometimes (more potential points of failure).

Recommended wattage for a gtx1070 is 500w and 30A. The 500w Hexa+ has 2x 18A rails for combined total of 432w,or 36A (not sure I believe that, usually split rails do not add as equal, 2x18A rails is usually 32A or so). So pretty much what you have is bare minimum recommendation psu with questionable numbers. This is enough to see some OC on cpu, but it'll be risky at best.

Unfortunately, it isn't the bare, bare minimum. You're kind of under that, which is why I recommended you get a better one. Overclocking aside, knowing the kind of torture a computer goes through while it's rendering anything, I doubt that PSU will hold up very long, if at all.
