Will my PSU be good enough for this? - Page 3

post #21 of 32
He may have 30A and 450W, but how clean is that power? Being a Diablotek I'll be very surprised if it gets anywhere near that power with ripple and/or voltage still in ATX spec.

Plus in your link all I see is 'maximum power 450W', which means it's probably peak power not rated power.

They may not be lying as such, but the phrase 'maximum power' on their website is enough to convince me that the wattage is peak output. Every other manufacturer that makes decent power supplies will either say rated power, continuous power or something along those lines. There's no telling how long that PSU can output that 450W for, a minute, or even a second.

Let's not forget the famous Diablotek RPM-1050W reviewed by JonnyGURU, which failed after just 600W. When tried to pull that power again it blew up and took his $200 Brand 4 power meter with it.

Not the same model exactly, but this is what I see from pretty much ever diablotek PS review I can find.

Some posts have been cleaned here, and you guys need to tone it down in this thread with the personal stuff, or there's going to be some 'formal' discipline being administered.

P.S. Diablotek are pretty much universally regarded as poor-quality power supplies that don't meet their stated ratings. I would avoid them, and if I accidentally got one prior to realizing this, it would become a priority to replace it unless I knew I was running it at WAY lower than the stated wattage specification ... or I just didn't care that much about the PC I was running it in

As aforementioned by myself, there's no need to buy something different; when want enters the picture, it's an entirely different story altogether.
There are a few reviews mentioned in this thread about other Diablotek units that have failed miserably. If a company is known to make pretty bad power supplies, I wouldn't trust my hardware with them.

The power supply department is one where you do not want to "experiment" with cheap units to see how they perform. Especially when your entire rig is at stake.

There's 105 reviews, with a 4.6 average, for the exact PSU in question.

Do any of those 'reviewers' have a load tester? Oscilloscope? Power meter? Or do they just give the unit 5 stars because it works and looks pretty?

For example, JonnyGURU reviewed the Sunbeam BKS580 580W PSU because it averaged 4 stars from more than 370 newegg reviews. Turns out it was a piece of junk that can barely deliver half its wattage before shutting down with ripple and the 12v rail going out of spec by 242W. The unit also had atrocious build quality with laughable quality control.

That is why Newegg/Tigerdirect/*insert online store* user ratings, especially for power supplies, are just pointless.

Corsair makes some of the best power supplies on the market. The CX500 is the best choice of the three options, but I would recommend to sacrifice a bit more on it for future improvements.
