Cross-Load Tests And Infrared Images

Our cross-load tests are described in detail here.

To generate the following charts, we set our loaders to auto mode through our custom-made software before trying more than 1000 possible combinations with the +12V, 5V and 3.3V rails. The load regulation deviations in each of the charts below were calculated by taking the nominal values of the rails (12V, 5V and 3.3V) as point zero.

Infrared Images

Toward the end of the cross-load tests, we took some photos of the PSU as it was being tested using our modified FLIR E4 camera that delivers a 320x240 IR resolution (76,800 pixels).

    I don't know of Rosewill is any better then it was a few years ago. I had friends with a rosewill PSU and it baked big time. Maybe they are better now. But I would stick with EVGA or another well known good company!!!

    i wouldnt hesitate to replace my ~7y/o antec TP750 with a nice rosewill capstone unit when the time comes. in fact, thats essentially my plan. would i throw any rosewill unit in my rig/s? no i wouldnt, but every manufacturer i can think of has units that are less than desirable. rosewill has a come a long long way the last few years

    Obviously EVGA has amazing brand name and they deserve it because of their level of service. However as far as i know EVGA does not have any PSU making plants, they simply rebrand a unit made by Seaconic or another OEM. Many companies do that, so you can probably buy exactly the same unit from a different brand.

    I am not sure if Rosewill builds or rebrands, but i had their products and they are not bad, i personally have not had any issues.

    Several Rosewill PSUs are build by Super Flower, the same OEM that also makes most of EVGA's offerings.

    I duno if their large ones are as good. But ive had a 550 watt running in this computer for 6.5 years now with no problem. This is the first roswell one i had tried. Thats the longest ive ever stayed on the same power supply.(In the past it was either fry, or had to upgrade the size because of ever increasing component power usage)

    Like every company that wants to do well into this market Rosewill doesn't rely on only one manufacturer. They had strong ties with Super Flower in the past however they decided to go with other OEMs as well, since SF became so popular and cannot meet the demands of all the companies that want their products.

    Does anyone actually do OCP, OVP, OPP / OLP, OTP, UVP, SCP, and
    NLO? (Something of a rhetorical question), short answer from google is no...

    Also, why is the list graphical? I'd like to have a character list to search through...
