"Specifications:

Brand: QMAX
Model: LC-8400BTX
Type: 24 pin ATX
Output: 400W
Compatibility: P4"

I bet maybe 250 watts output on it's best day I would "maybe" use this power on a Pentium 3 computer found on the curb.

In other words IMO it's a POS.

This model is from Soly-Tech. The PSU has 65% efficiency at full load. They have an 80 plus model too.

Edit: edit for stupidity =)

So I wasn't that far in my estimation.

65% = ick!

Where did you get the 260W figure? I thought PSU wattage was supposed to be the power that is delivered from the PSU to the computer. So it would deliver 400W to the system, but it would draw 615W from the wall socket.

615W from the wall ===> PSU ===> 400W to computer
400W/615W = 65% efficiency

Reverse numbers is where he got that from I take.

I don't think IMO that power supply has any punch nor puts out with a short lifespan if it doesn't take out computer components first.

Good things come in small but powerful packages thanks to QMax. This 400-Watt power is the most compact, energy efficient power supply in the business!

since i don't know the amps of the rails im gona assume its a single 16 amp rail or mabe dual 12amp ones which if u calculate that out its 192w 12v rail so adding in the 3.3v and 5v rails i would say his 260w calculation is right.

most cheap PSU makers (Most cheap company's in general) put the max load on the psu but u should not use the max for more then a few seconds. Quality company's like corsair, seasonic, so on... their psu might say 400w but that is usually the constant load u can put on it, and it should have a max load of around 100w or so more.
