PSU manu and watts, input needed?

I need to upgrade my power supply. I have a antec 300w now, need more juice, uncertain what manus are good? antec, thermaltake, enermax? I'm thinking 430w and above? Any input is welcome, Watts and Manu??!! Thnx Obi

OK, I am in a good mood today (rare!), so this is what I posted....


Well, all of the above are good PSU's. I have an Antec TruePower 480 (futureproofing!) and it's superb. Enermax seem to be the PSU of the discerning THGC member tho! As a UK resident tho, they're rarer than rockinghorseshit!

430w should do you, but when I asked pretty much the same question on these boards, the advice I got was "Get as big a PSU as you can". And it's good advice. If you got the cash to go higher, do it!

Enermax is slightly better than average and not worth any price premium. I don't know who makes Thermaltake. Antec is very good, and you get a 3-year warranty, but they're not better than Sparkle/Fortron, and the latter is available from www.directron.com and www.newegg.com for low prices. Tom isn't the only person who's found that Antec Truepower and Fortron/Sparkle are much more powerful than most 400-450W supplies, so be skeptical of manufacturers' ratings.

Another vote for the enermax....sparkle/fortron were good power supplies back in day...but they do NOT supply enough +12V power for most high end systems...you do the math...a 400watt sparkle power supply according to their website only supplies 15A on the +12V rail....Hell a p4 2.8 consumes at least 8A alone not taking into account case fans, harddrives, etc...that would be taking a chance on instability

Antec switched suppliers from HEC (Heroichi) to Channel Well Technology today, I believe starting with their Smartpower and Truepower series. But HEC has been known for good supplies, and some Truepowers blew high voltage filter capacitors, either because the capacitors were defective or the surge reduction (thermistor, soft start) turned on the supply too quickly.
