Is Corsair CX430 enough for this build?

Mithcah · Jun 4, 2013

Intel Core i5-4570 3.2GHz Quad-Core
PowerColor Radeon HD 7750 1GB
MSI H87M-G43 Micro ATX LGA1150
Western Digital Caviar Blue 1TB 3.5" 7200RPM Internal Hard Drive
Samsung 840 Series 120GB 2.5" Solid State Disk
LG GH24NS95 DVD/CD Writer
BitFenix Shinobi ATX Mid Tower Case
Crucial Ballistix Tactical 16GB (2 x 8GB) DDR3-1600 Memory

Is the Corsair CX 430W psu enough? No overclocking (hence the non-k cpu), might add a backup 1TB HDD like a caviar green or something

Thanks for advice!

Yes it is.

DarkSable · Jun 4, 2013

That will be plenty, yeah.

Get this one, at least it's verified Haswell compatible whereas the CX430 isn't.

For a system using a single Radeon HD 7750 graphics card AMD specifies a minimum of a 400 Watt or greater system power supply. The power supply should also have a maximum combined +12 Volt continuous current rating of 20 Amps or greater.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the most critical factor.

The Seasonic G Series 360W (SSR-360GP Active PFC F3), with its maximum combined +12 Volt continuous current rating of 30 Amps and with one 6-pin PCI Express supplementary power connector, is more than sufficient to power your system configuration with a single Radeon HD 7750 graphics card.

That PSU is just fine, but I still recommend getting a 600W PSU so you can have some room for upgrading in the future should you ever find that GPU not satisfactory and want to upgrade.

If you added a 3rd hdd to that setup, the psu would most likely not be enough. Without a 3rd hdd, the PSU should just cover it with around 30W-40W to spare. I'd personally get a slightly higher wattage if you plan on upgrading.

Any particular reason?

H4mmersmith · Jun 4, 2013

**20W-30W rather. Accounting for spin up, not just normal use. Also accounting for the possibility that the PSU doesn't reach its labelled capacity.

How is that possible? The max power draw on the CPU is something like 80W from memory? Taking into account the system being at peak usage, there is no way in hell it'd run at 100W.

From what i can see the GPU uses around 40W when gaming. So at about 120W at around peak levels, not counting all the other components 100 - 150 watt would not cover it at all.

Well that has already exceeded the 100w/150w you mentioned. Add wattage for the 16 gig of ram (as small as it may be) and it keeps pushing the power consumption over what you have stated.

H4mmersmith :

Right... since when do RAMs eat more power than CPU?

H4mmersmith · Jun 4, 2013

Not sure where you're reading that? Never said RAM pulls more power than a CPU?

Yeah your 150 watt guess was fairly close. You do realize although no external power cable may be required for the card, it still draws that power from the PSU? So unless the power that's provided to the PCIe slot is magic, the 120 watts i stated is fairly spot on.

Either way we're looking to much into this haha.

4 watts your grasping at straws my good man, the 7750 is all pcie slot powered no external connector needed. The pcie slot max rating is 75 watts no way it will reach 120 watts as you stated. The 430 is 80+ bronze certified = 344 watts. And your talking ram ?

My 150 watt guess was very close based on the specs given.

Actually, 430w and 80+ certificate means the PSU will draw 430/0.8w from your electricity lines when it reachs its maximum 430w output.

Sounds like your head is running wild from this point.

You do realize when i say 120 watt, i'm also including the cpu wattage?
