PC Power Supply Stress Test

[HAVOC]

UPDATE:
They have completed testing on 3 units.
PCP&P Turbo Cool 510w - Passed - Loud, Solid, Efficient
Antec True-Power 2.0 550w - Failed - Highly unstable in 12v rail
Be Quiet's BQT B5-520W-S1.3 0 Failed - Blown fuses

hmm crazy....neat little boards that have places for the 20pin and 24pin main connector and just suck all that juice out

I think something will blow.

Anyone wanna make any friendly TF bets on which ones stand the test?

I'm betting the house on the PCP&P 510 & 850.
Antec will probably will be close...

# Coolermaster RealPower 550W
# Hiper Modular HPU 4B480MU
# Fortron Group (FSP) Zen
# HEC AcePower 480W
# Antec TruePower 550W
# Antec Phantom 500W Hybrid
# OCZ PowerStream
# PC Power & Cooling Express/SLI 510W
# PC Power & Cooling 850W SSI
# Enermax Noisetaker 600W

PCP&C will win, but between Antec and OCZ its gonna be tight. Ennermax will prolly come in after those. Everything else is crap


EDIT: LOL we sound like were discussing sports lol

 

[HAVOC]

lol - yeah... That's what I think too dhw200.

PC Power will win by one touchdown

PCP&P Turbo-Cool 510 was their first candidate. It survived 24 hours of abuse at full load without failure. Although very loud, it's efficiency was 78.8%. Which is pretty solid for the 500watt class.

Why are they not gona do silverstone? It's a really good brand! Read the reviews! It's kinda new so not as many people know of it, but I will say that mine is just as good if not better than the 520W OCZ modstream! It's also a bit pricy, and the actual PSU is very heavy, which is good (i think). Rock stable voltages even OC'd. from 2.2 to 2.7 with ram at DDR492 @ 3.3V !CPU at 1.525V.

I don't think the ModStream will perform very well under this stress test. Modular Power supplies are trendy and pretty cool looking, but they have a flaw.

The fact is, modular plugs limit power by adding to electrical resistance. The voltage drop can be as much as would occur in 2 feet of standard wire. Worse yet, modular plugs utilize delicate pins that can easily loosen, corrode, and burn, creating the potential for a major system failure.
