Kill a watt question question

[zalazin]

System Specs:
Gigabyte GA-945GCM-S2C, Celeron E1200 Dual core, 2Gigs 0f DDR2800,Samsung DVD burner and HD4850. WinXP/VISTA Dual Boot. WD320 HD

Athena Power MP4ATX400 SFX MicroATX PSU Specs ARE:

+3.3V@12A,+5V@19A,+12V@20A,-12V@0.8A,+5VSB@2.5A

On my Kill a watt when running 3d mark advantage I see 318 watts peak. How does that relate to the power supply? Since the PSU is not 100% efficient about 65% is it only putting out only around 206 watts? So far the athena psu is holding its own. I don't fully trust the athena PSU there are mixed reviews about it.

It is hard to say. How do you know the PSU is 65% efficient?

Sadly Kill-A-Watt's are more inaccurate than most people think. I have a Watts-Up-PRO and I can say its far more accurate than my Kill-A-Watt is. Often get deltas between the 2 nearing 40 watts or so at the worst times. Get what you pay for I guess. Just make sure its a newer model, I heard old ones suck.

^ That Watts-Up-PRO is also way more expensive. I think the Kill-A-Watt is designed to give you a rough estimate.

Rough estimate is an understatement.
