Titus Posted February 17, 2008 Share Posted February 17, 2008 I will be doing a complete system upgrade next week and was deciding between the HX520W and HX620W PSU's...I see the HX520W uses a 12v rail rated at 40A while the HX620W uses a 12v rail rated at 50A I thought a 40A 12v rail was the minimum recommendation for high end systems these days...is it OK for me to go with the HX520W or should I go for the beefier HX620W? (taking ito consideration that I might later upgrade to quad GPU's and a quad CPU) also the TX line uses non-modular PSU's...is that better to use then modular? (PC Power and Cooling makes a big deal about this saying that consumers should only use non-modular PSU's) my planned system specs: E8400 8800 GTX Ultra ASUS Maximus Formula (X38) 2 Western Digital Raptor 150 in RAID0 DVD-RW Creative sound card Cooler Master CM-690 case Link to comment Share on other sites More sharing options...
EliteKiller Posted February 17, 2008 Share Posted February 17, 2008 If you can afford all of that fine hardware in your sig then surely you can afford the HX620. ;): PCP&C (eg. Doug Dodson) voices opinions thru their website and interviews. Keep in mind they offered multi-rail psu's for years, but now all of a sudden they are taboo. They also shun modular designs claiming "voltage losses". Funny thing is now that they are part of O©Z I wonder how they feel about O©Z's modular & multi-rail psu's. Obviously a single 12V rail is a good thing, especially if you are a fan of Corsair psu's. The HX1000 will be hitting the review sites soon, and we'll be able to see how much those modular connections are contributing to voltage loss on a "high power" psu.

Titus Posted February 17, 2008 Author Share Posted February 17, 2008 is a 40A 12v sufficient for even the highest end systems nowadays? Link to comment Share on other sites More sharing options...

No, and keeping your future upgrades (C2Q + 3-way SLI) in mind you should consider the TX750 at a minimum. It's capable of handling a 900W load. :D: Read more: http://www.hardwaresecrets.com/article/505/1 This unit also has all the basic stuff everyone is looking for nowadays: high efficiency, active PFC, excellent cooling solution, enough power to feed high-end video cards, five-year warranty and the best of all: it can really deliver its rated 750 W at 50º C. Not only that. During our tests we could pull up to 900 W at 45º C. So you will be basically buying a 900 W power supply paying the price of a 750 W one. What is sweeter than that?
