Manticore Posted October 17, 2010 Share Posted October 17, 2010 Hello I've recently tested my psu with a coolmax ps-228 (similar to 224) psu tester. Some info on test config: 24pin (mobo) and 8pin (cpu connector) are to be attached during testing, plus 1 other peripheral at a time. With a rosewill green 430 (530 peak) my pci-express passes test but my hx1000 will not unless I unplug the cpu connector. This goes for both pci-e and at least 1 blue modular (tested so far). The error I receive is thus: LL (low) for -12v and HH (high) for PG (power gain) the -12 displays -11 to -13v and pg 0ms to 990ms. Does my psu need to be rma or is there a minimal load requirement of some sort for this psu that this tester may not meet. All aspects of pc seem to operate fine so I am a lil confused on this matter, any help is greatly appreciated! Thanks! Link to comment Share on other sites More sharing options...
Manticore Posted October 20, 2010 Author Share Posted October 20, 2010 Bump, well seems with my new pc build with i7 930 I have internet inconsistencies which may possibly be because of the psu... Considering I've gone through 2 rampage III genes now(testing).... Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted October 20, 2010 Corsair Employees Share Posted October 20, 2010 I spoke with an engineer and found that the dual rail nature of the HX1000 may cause problems with some PSU testers. It would be unlikely that the PSU would be the source of software related problems, but to be sure I would test the PSU in a different system and see if the problems follow the PSU. If it looks like replacing the PSU may resolve the probelm then please Request an RMA. Link to comment Share on other sites More sharing options...
Manticore Posted October 21, 2010 Author Share Posted October 21, 2010 Thx, I guess Ill just have to build another system or swap to know for sure. Thx for info. If I were to borrow/buy a multi-meter would there be anything special besides general guides online for testing this psu pci-e? Link to comment Share on other sites More sharing options...
SparkyPSU Posted October 21, 2010 Share Posted October 21, 2010 Actually yes a PSU can cause operating problems in software it is a well known phenomenon with satellite television receivers (and similar such devices that run software and have a switching type PSU) as they also use a similar design of psu to a pc and they run an O/S which can be corrupted by the PSU - a multi meter could show up your problem but it would need to be a true RMS type of meter to be accurate and / or fast enough to spot anything - moving coil/needle pointer meter would be useless - an oscilloscope would find it if you checked it under load and the 'scope was fast enough i.e. MHz.

Wired Posted October 21, 2010 Share Posted October 21, 2010 He didn't say it couldn't, just that it was unlikely. Link to comment Share on other sites More sharing options...
SparkyPSU Posted October 21, 2010 Share Posted October 21, 2010 It is highly likely PSU design can cause operating errors - any ripple on an output will have an effect on any device that relies on clock timing cycles to synchronise data pulses - the real question is how much ripple is present on the output and how tolerant is the device being powered by the psu of the psu's ripple - and if the PSU is faulty or has a design quirk or a design fault you will suddenly find out all about what performance under such and such a load really means in practice not just in theory!
