Is this PSU enough?

[mgsolidus]

Hey everyone.

 

I intend on upgrading my computer soon, and I'm wondering if an XFX 450W 80+ Bronze PSU is enough to power this,

 

i5 4690k overclocked to 4.3GHz

Nvidia GTX 760

MSI Z97 Gaming 5

 

I currently have an i5 4570 + Radeon HD 7790 which works just fine.

An online PSU calculator estimated 435w at 95% load and 10% capacitor again, but I'm not sure how accurate they are.

 

Thanks!

it doesnt hurt to try the computer just wont work if there isnt enough power

Linus said to get a PSU that will give you some headroom. So I think a 550 or 600 watt will be good enough. IMO

The brand is good, XFX is from Seasonic, but 450W isn't enough.

 

550W is the minimum without overclocking, 600W is recommended and you can overclock a little (4.3 GHz is fine), and 650W is with overclocking and if you have a lot of expansion.

Yeah, it should. I still recommend a 500-750W PSU so there is overhead room for upgradeability.

Also, when a PSU is at around 90% load, the efficiency drops like crazy.

if your PSU has a 6-pin and a 6+2 pin (or 8-pin) GPU cable it should be fine

Pretty much this.

What XFX is it specifically? Generally if it's a good quality PSU then 450W is just perfect for those specs

450W is plenty >.> Even for overclocks on the CPU/GPU.

34amps on 12V rail. There's only one model from XFX thats 450W with bronze efficiency.

It has a 6+2 pin.

I would suggest going for a 500w PSU at least, never ever aim for the lower wattage PSU that will suit your system (albeit there's no way you're ever going to use it @100% load either), there are just too many contra-indications. You should always leave some room for future upgradeability or should anything happen to one of your components and you have to replace them with ones that need more power. Also lower wattage PSUs tend to have their fans spin generally faster even at low power consumption and that unit is not really a very high quality one. Please do not cheap out on such a crucial component.

 

Also, if that is the PSU that is powering your current system I would suggest to upgrade it anyway.
