700W to 850W PSU Group Test - Bit-Tech roundup

A pretty well written round-up, with an interesting selection of power supplies. Not as deep as we are used to seeing around here though, but a good read for those "stuck" in the UK. :p

Not sure I entirely like the methodology when both Seasonic and Etasis get somehow rated below Tagan and Enermax :p

Etasis would have thought of the hotspot issue and chosen appropriate components... I would have pulled it apart to make sure of that before recommending against it just for running hot.

I'm surprised the 5V dropped out of spec on the Hiper when it was loaded. It's not like it was a crossload and they didn't overload the 3.3V+5V combined. And AFAIK that PSU has independent regulation.

[Oklahoma Wolf]

I'm not too surprised - they had it 2A away from the max spec on that rail it looks like.

The X-Pro did that too when I pulled the two drives out of the HTPC, but then again it really was badly crossloaded at the time. I wonder if the Hiper would stabilize with just a bit more 12v.

[jonnyGURU]

Yeah. And I just checked Matt's review and noticed he didn't do a high 3.3V and 5V crossload test like I try to do. :(

Odd, no one else is getting a HTTP 403 Forbidden message from that site? No matter where I am, I can't get onto it.

[Oklahoma Wolf]

Still working for me. Just realized there's no mention of the equipment used or methodology either.

No, Matt did the same tests that you had already programed into the SM268 when you sent it to him ;) If you want though I'll start doing six tests with a crossload test after the first five static tests are done. Lower the 12V on test five and raise the 3.3V and 5V rails to maximum.

[Oklahoma Wolf]

I'd be interested in that - my X-Pro was fine with the 5v based motherboard and 4 hard drives, but as soon as I took two of the drives away the 5v rail tanked hard. You could see the power LED on the front of the case flickering. Probably had less than 2A on the 12v rail at the time.

No. But it's definitely a Chroma. :D Looks like a series of 8xxx tester. Just on a bench instead of in a rack.

Up to you man. Until I'm actually cutting my guys paychecks, I can't be too demanding. ;)

I have melted power supplies at lower temps than that. :eek:

[Oklahoma Wolf]

lol - I know, but Etasis designed those things to run full out in hot environments... I have to believe internal temps were carefully considered in the design stages. They probably measured at a 125 degree rated MOSFET or something.
