Enough Power?

[jonclancy]

Hi All,

I've got a Haswell 4570 to bung into a box to make an economic system for home. I'm re-using a Cooler Master case which come with an Elite Power PSU. It's a 460W unit.

We'll be using the onboard HD4600 graphics for the time being, and an SSD, DVD Writer, mouse, kb, etc.

I'm tempted to build in a bit of future-proof by splashing a few more quid on the mobo - having just read Stulid's excellent review of the GA Z87-D3HP.

Might be used eventually for overclocking a Broadwell chip!

The Gigabyte D3HP manual states:

"To meet expansion requirements, it is recommended that a power supply that can withstand high power consumption be used (500W or greater). If a power supply is used that does not provide the required power, the result can lead to an unstable or unbootable system."

Seeing as there isn't going to be a dedicated GPU in this build initially, and the 4570 has a TDP of 84W, will running 10% under-powered really be an issue?

Maybe go for a cheaper mobo and a new PSU, perhaps?

Any suggestions gratefully received!

The PSU did not get a great review, but as you mention your using onboard gpu the PSU should cope without issue, even though your not meeting the power recommendations from the manufacturer your PSU is still a lot better the than £10 - £ 15 cheap versions!!

Seems pretty safe, I'm on 430W for a 95W TDP processor with discreet graphics (86W peak draw gfx card)

Edit: Maybe worth mentioning though that I'm considering getting a higher wattage PSU at the moment to allow me to upgrade my gfx card, as at the moment I could do it but wouldn't be able to overclock.

Thanks guys. I'll get the mobo ordered and see how I get on.

I didn't realise that the D3HP also has onboard graphics, too - just chuck in a processor, SSD and some RAM and you're off!
