Hi guys, I wanna build an HTPC for my family ( they gave me a budget and I do the dirty work...). I've got most of the components sussed out.

But there is one thing I'm hesitating about. I've chosen a case which is the Antec NSK2480, it comes with an Antec 380W PSU (I'm assuming it's an Earthwatts, as it's an 80). The question is will that PSU power an ATI 4650 (and the rest of the rig) for HD playback on my TV or is that (gfx power) overkill and I should just stick to a 785 chipset mobo (AM3) with an integrated HD4200?

Thx in advance Mojito

Yes. The 380w is plenty for your system, with or without the 4650.

I got a antec neopwer 550 and it does well with a 8800gtx so with you ea385 you will do fine and have room to upgrade later on. PS the ea650 isn't that great.

Plenty of power for a HTPC.

Hell my E6600(not all the power efficient) + 8800GTX(same here) system runs on a 450 watt Smart Power(this thing only has a MAX of 32 amps on 12 vs 27 on the EA380).

You should not have any problems at all. The ATI Radeon HD 4650 video card is an energy efficinet card. During stress testing which is much more power demanding than home theater use, a system with the 4650 peaked at a maximum power draw at the wall outlet (mains) at 185 watts. That's for the entire system.

Here is a link to a power consumption chart:

It's quite annoying, when manufacturers say that you need atleast a 400W.

Video card and power supply manufacturers overestimate power supply requirements because they know people insist on buying low budget power supplies of questionable performance and value.

About to a 4850 or 9800gtx.
