What psu for htpc

Amd Phenom ii x3 720 triple core process...
July 21, 2009 at 13:06:28
Specs: Windows Vista, Phenon 2.2ghz 4gb
I am considering building a compact HTPC for use in my living room.

I need some advice on which PSU I should use for my intended system.
It must have a modular cable system as it will be a slimline case with limited room.

Below I will list my chosen components.

AMD Phenom II x3 720 2.8GHZ black edition
Asus motherboard M3A78-CM micro atx
Crucial 2x 1gb ballistix 1066mhz
2x W/D 250gb Caviar (RAID 0)
Sony Blueray Drive
ATI Radeon HD 4870 512MB

My question is what would be the perfect modular psu for my intended HTPC build?

There are several things wrong with your configuration...here's the list, in no special order:

1. Modular PSUs are not the best choice...there are too many connections that can burn out or fail. You'd be better off with a standard hard-wired unit.

2. You are not building a HTPC, you're building a gamer. An HTPC does NOT require a triple-core CPU, gaming video card or a RAID-0 configuration. Raid-0 is NEVER a wise choice for a home user...gamer or otherwise.

3. There are better motherboards for the money & if you look again at the specs of the board you selected, it does NOT support the Phenom II.

You need to totally rethink your configuration. Here's an alternate list that's cheaper & quieter:



CPU choices:





video card:

"I am building a HTPC/Gaming system"

You didn't state that in the origianl post. And I just checked the ASUS site & apparently that board will support a Phenom II after a BIOS upgrade...depends on which BIOS it ships with. RAID-0 is still a bad idea though.

Here's some info about modular PSUs:

Why do you think raid 0 is a bad idea for a HTPC?

Also any impressions on this MTB i came accoss its the latest AM3 micro atx.

Raid 0 is a bad idea for any pc. To speed up disc acess Raid 0 will write half a file to one disk and half to the other. Problem is that if anything happens to one of the disks, that file would be useless. If it's a system file, then the system is useless. One drive crashes, they're both down; there is no redundancy with Raid 0.

If you're going for faster, buy the fastest hdd's you can afford.
