Newegg sent me a coupon for 10% off Antec PSUs so I'm wondering if I should upgrade from my NeoHE 500 to the TruePower New TP750. I've had intermittent instability problems for years and the only components in common between builds are my PSU and my X-Fi. Although I think the cause is my X-Fi, I am nonetheless faced with the opportunity to get a better PSU for $90 ($10 less than my Neo was back in 2006) and virtually assure myself that power quality is not the issue. Plus, I'd be future-proof for the new build/upgrade I may do this summer.
