Would these components run on a 450w PSU?

Hello everyone, I've got a FSP PSU with a DC output of 450w. I'm looking to upgrade some components, as my PC is getting on a bit and can't run the games I want to play that well.

I was looking at the Asus Nvidia GTX 750 Ti and the AMD FX-6300 as upgrades for my system. But would these run on my PC with a 450w PSU?

:confused:

Here are my current specs:

AMD Phenom X2 II 565 3.40Ghz (Upgrade to FX 6300)
AMD Radeon HD 6790 (Upgrade to GTX 750 Ti)
ASUS M5A78L-M/USB3 Motherboard
4GB DDR3 RAM ( 2x2GB )
1 x WD Caviar Green 1 TB

Hope you can help as I've posted on other well known PC hardware sites and haven't had the best response.

Thanks!
 
Its actually hard to say without knowing exactly what PSU you have - some PSU's are not exactly quiet but that system shouldnt pull more than 350-400w - you may find the unit gets warm or the fan spins up a bit if its one thats not great quality

Not to mention that cheap PSUs cannot always consistently output their advertised wattage. Make sure it's of decent quality and can actually output 450w.
 
you should be just fine, I had i7 4770k ocd and 770 ocd at the time +3 drives, running from 5year old 500w corsair psu.
 
What is the rated 12v rail Amperage? I recently tried to power up a FX-4100 and old AM3+ board with a CiT 600W PSU and while it would boot it always failed at installing windows as the PSU simply crapped out during loads causing BsoD, true testament to "don't scrimp on your PSU" you're going to need 24A minimum on the 12v rail to run a system.

Corsair
XFX
Seasonic
EVGA
Superflower
(all quality PSUs)
 
Ok, I'm thinking of doing the GPU first, then going from there.

Thanks everyone for your help. Much better responses than a well known hardware site. (No names!)
