Hi all, I was wondering if anyone could help me - My build is roughly 6 months old, no problems until today. I've tried to power my PC on and the PC boots for around 0.5 seconds and then turns immediately off, upon doing such as re-seating RAM, trying one stick, ensuring all cables are working, ensuring Fan header is connected etc etc I decided to try my old PSU from an older build and have found the PC boots from this, upon re-connecting the 650GS i've tried other wall outlets to ensure it isn't the connection to the PSU, however this also results in the PC booting for 0.5 seconds and shutting down. Before I look into how to get a replacement, is there anything else that could be causing the PSU to have this issue that I'm not aware of? Thanks in advance

Welcome to the EVGA Forums As your old PSU works correctly when you swapped it back in - it seems to be an issue with your 650GS or its cables Clearing the CMOS is about the only "test" that comes to mind with the limited information that you did post Some MB will cycle their BOOT several times - when adjusting themselves for various reasons, including OC failure, RAM testing ....... Would be nice to have more details: MB & BIOS version ? CPU GPU OS If the PSU is shutting down it could be a "safety feature" that is being tripped and your old PSU may not have this "feature" Disconnect the PSU and test if it will start & run by its self https://www.evga.com/support/faq/afmviewfaq.aspx?faqid=59582

Hi Cool GTX, Thanks for the reply, I Have a Z370-I - unsure as to the bios as i've removed the old Power supply as i don't trust it in my newer system CPU - 8600K GPU - 1060 2GB Win10 - 64 Bit The system isn't currently running an overclock, I'll find a paperclip and run the test now and let you know the results. Thanks for all the help.

Ok so, I've reset the cmos - no boot I've followed the paperclip test - there is a noise that happens very quickly and then nothing happens, no fans spin. Thanks, xtz

A very quick web search, did not see any in depth reviews for that OCZ PSU Not sure if I'd want to "risk" my new PC build with that .... (found this on jonnyguru) OCZ GameXstream 700W (excerpt from link above) "The Bad.... Ripple that exceeds tolerances documented in the ATX specifications"
If you do not have a friend with a quality spare PSU, it might be worth the advanced RMA fees if that is an option ... ask EVGA Customer service. Otherwise: - you ship your PSU (from where & Christmas shipping delays & schedules.....) - EVGA gets your PSU & add about 3 or 4 business days for the item to be inspected (but nothing during announced shutdown ) - then the shipping back to you .... however many days that takes
