well imo I love this thing, modular, was $80 for 550watts, 20amps on each 12v line. Looks great too. How come this thing doesn't get any praise around here? Instead people just want to pay $100-150 for the same deal?

That is because it exhibits very poor voltage regulation, unacceptable low frequency ripple and isWhatTheSchmidt said:How come this thing doesn't get any praise around here?
Why should they when a Zeus ST56ZF or a Corsair HX520 can be had for the same price?Instead people just want to pay $100-150 for the same deal?

I think this PSU might have been the cause of some random reboots(when playing flash games and when running 3dmark) and the black screening during the flash games? The game would freeze up then the screen went black for 3 sec then all back to normal.
Anyone know if that's the cause then? If so I'm gonna sell/return this PSU and get a different one.

That said, the XP units are halfway decent. They're the closest things at Mushkin to an old Powerstream, and about the best Topower built units out there (that's not saying much). Problem is, the HP stuff isn't Topower's finest. Topower is infamous for old unreliable designs, and the HP-550 is a shining example of that.

it's a new build and it's in sig...hard drives 74 gig raptor and 250gig WD are from old rig.
If I were to run 3dmark a few times(I know 05 caused a reboot when I ran it for the first time) it would probably happen.
When comparing the cold load to the same hot load, we see that there's as much as a .06V drop during test two and .07 during test three. The performance score just dropped to 6.
Just when you thought it could get worse... the crossload tests cometh! With a 3A load on the 3.3V rail and a 4A load on the 5V rail and 14A on each 12V rail (all within specification) the 12V dropped to 11.24V! It took taking the 3.3V up to 5A and the 5V up to 8A to get the 12V rail back up to 11.40V.
This power supply has a pair of +12V rails, each set to do 20A. The combined 12V capability is 336W, or 28A.
WhatTheSchmidt said:it has rail fusion and max combined is like 34A i think...can't rem don't feel like looking
