What sort of spec for my brother

Surveyor · 20 Aug 2011 at 23:37

FYI for anyone considering the BeQuiet Pure Power L7 530W '80 Plus' Power Supply.

Custom PC have just had one of their big PSU tests.

The BeQuiet has two 12V rails with a quoted maximum combined output of 35A.

In the test the maximum combined output they could draw from 12V rails was 28.5A so they weren't impressed.

Possibly a bad sample but it doesn't look good.

it was almost certainly a bad sample. for a company like bequiet its highly unlikely that they'd get their power figures wrong

Cheers for the info, thats another item to scratch of the list

what about the three reviews (albeit in german) that have had no problems with the PSU :confused:

even a truly pants reviewer would notice if the PSU doesnt deliver all of its rated power

Nah, I sure theres something better for the money.

Like I said, it possibly is.

I've reported the test results and you can make whatever use you want of them.

They also reported a 5V rail only just within ATX spec at 4.78V at full load and a mediocre ripple test of 29.2mV. The best PSU of 400-599W had a ripple test result of 8.1mV.

Nah.

you really think that someone wouldnt notice that it wasnt delivering all the power it claimed to on a 100% power test. (which these reviewers did)

Any idea what was good for the money? around £50?

hmm, this is another problem i dont have with my PSU. yes i can only load it to ~310W but the 5V rail is pretty steady according to ASUS's monitoring software. the 12V dips to ~11.8 but theres nothing wrong with the 5V

You're unlikely to be using anywhere near the full load on the 5V rail.

soooo, wheres the problem with it not being so steady on the 5V rail when maxxed if you arent ever going to max it out? surely its like saying a mobility scooter is unsteady at 60mph

They didn't really test much around that sort of price.

Unsurprisingly the best PSU was the Seasonic X-560 but it's £100.

The Corsair Builder Series CX430V2 came out quite well but it only has a 28A 12V rail and a single PCI-E connector.

The only other £50 PSU of mention was the Thermaltake SP-530PCWEU but this isn't sold by OcUK and is another one without braided cables.

Ok, Thanks for that.

I'm not arguing with you about it, I'm just telling you the results of the tests.

Just pretend I never said anything and carry on as you were.
