I am going to buy a PSU and it is lot of types to look at but i found one wich i somehow find to look trusthworthy and it is a good trademark in cooling solutions but i have not heard anything about their PSU but it is heavyweight and somone here says more weight more quality but below here is table of numbers of what it deliver of watts and volts. ZM460-APS AC Input Range Voltage 100VAC ~ 240VAC ±10% DC OUTPUT Frequency 47Hz~63Hz Output V.

Zalman's PSU's aren't as easy to find, and that seems to be a bit pricier than similar power supplies. If you're into silent, or near-silent computing, that might be worth a look. The specs are quite decent, and while I personally don't have any experience with Zalman's products in general, what little I have seen and read has been positive. On the flip-side, you can get some equivalent or more powerful unit's for less or equal pricing from the likes of Antec and Enermax. Newegg lists some very inexpensive Fortron (FSP Group) AX400-PN and AX450-PN units for $39.99 & $49.99--respectfully-- that provide nearly the same specs (450W in particular). From personal experience from the FSP Group's Sparkle brand, if you want a cheap, but solid power supply in that wattage range, I'd would definitely look at the Fortron AX450-PN. Now, I don't know if it's going to be as quiet as the Zalman, but outside of the probable lower noise output, I'm finding it very hard to find a good reason to recommend paying $100 for that power supply. If you can find it for, say $60-70, I'd go for it, but the prices seem to be closer to $100, and I can't recommend it over power supplies that are just as good, if not better, that you can find for nearly half the cost.
