There are three important priorities in a good quality PSU:

1. Voltages that are all within spec and remain there under all loads

2. Full advertised current capability, especially on the 12v rail(s), with low electrical noise and ripple

3. Quality PSU components that will last years under 24/7 use

Everything else is of far lesser importance such as how pretty the box is or if the cables are modular, etc. The trivial items may be importance to some folks but your PC could care less about this stuff as long as the three criteria above are in place.

The UL code on the PCB suggests that the PSU is manufactured by Yi Li An Electronics (Shenzhen) Co. Ltd, but I couldn't find any detailed info about it.

Looks like Sirfa: http://www.hardocp.com/ar...er_mkii_950w_psu_review/3

Scythe uses Sirfa, so yeah. I'd say it is. The heatsinks are typical of that company.

what UPS did you use? if you mentioned then I must have missed it since I did not read the full article.

I have the Antec Neo Eco 520 and sure enough it too will not work on the batteries with my UPS. I have the CyberPower CP1000PFCLCD UPS 1000VA / 600W PFC compatible pure sine wave UPS.

so who do I need to complain to since I have no protection under load? Cyberpower will blame Antec and Antec will blame Seasonic. in the end I paid 150 bucks for a UPS that is worthless if the power goes out under load.

I'm guessing the "compatible pure sine wave" is the issue so if true then the issue is the UPS not the PSU. The transition time can also be the issue if it's 8 milliseconds or more.

I discussed this with APC and they have three series with pure sine wave that does not have issues with PCF PSUs.

Low cost UPS units typically do not have true sine wave and that's what typically causes the issues.

I would be glad to hear if you use any double conversion online ups like surt10000xlt ? Thanks for introducing 600 to 850w psu, very good
