should I use a cheap china psu on my htpc?

post #1 of 10
Thread Starter 
i know, i know....i have read all the horror stories, so i am building this little htpc for watching movies and 720p and 1080p playback with a entry level AMD 6000 GPU and a midrange intel dual core. its actually an upgrade from my old athlon 3000 build and the whole system will consume under 250W at load. It will have a single hard drive and a dvd player slash burner, a sound blaster card and thats it. I dont have any psus at home but this EXCEL 400W PSU (pos no name made in china). its been running my athlon for the past two years without any issues. So I was wondering if I should go for it and use it on the new build? I got the parts for almost next to nothing and wasnt planing to spend ~$50 on a better "branded" PSU.

need some advice redface.gif

I don't see why not.

Do you have a clear picture of the label?

Anyway, if it ran another system for two years, it should do okay with another low-power system. I mean, worse thing that can realistically happen is that the thing decides to die and kill everything else in the computer, but if it's just cheap stuff and probably no important data in there, it's not a huge deal?

If it's not too noisy for your tastes I'd just run it. Rosewill Green Series 430W is going to be quieter and probably considerably more reliable though, for $38 shipped:

Ya, i can read it, it doesn't say a lot tho, here's what it says,

EXCEL
Model ATX 400W
Max output power is : 400W

INPUT
115 VAC
10A MAX
60HZ
230VAC
5A MAX
50Hz

OUTPUT
+ 12V 18A MAX
+ 5V 40A MAX
+ 3.3V 28A MAX
- 5V 0.5A MAX
-12V 0.5A MAX



the most my system will pull at peak 90% - 100% load will be around 250W. But i really wouldn't want to have my components destroyed since they will have some data but I understand that there is a chance. i mean i did get a bargain from my friend since I got them pretty cheap but the components are pretty decent imo. I mean its a nice sata hdd, a nice mini atx mother board some decent ram and a nice dual core cpu along side a entry level amd 6000 gpu, so wouldn't just want them to die on me. the PSU itself is quite with a 120mm fan and has a 24Pin Adapter, a 4 Pin mobo power cable, and 4 molex connectors(no sata) but I have a molex to sata connector. So I am still not 100% sure what to do.

I wish I could grab that rosewill, but where I live atm (nz the down under crap hole) everything is scarce, triple priced. Cant get a decent used 500W PSU such as coolermaster, antec, silverstone or crosair for under $50 + shipping. frown.gif

Oh, NZ, sorry. That seems like an ancient design since the +5V / +3.3V output is relatively high compared to +12V, which is...hardly recommended to run a modern system. You're essentially crossloading it out of its comfort zone in terms of operating conditions, most likely. That's not to mention that the -5V rail was abolished in 2003. rolleyes.gif

You can try searching the UL number (if listed) to see if that leads to who the real manufacturer is.

Even if you're talking HD 6670 (entry level is technically like 6450, right?), I wouldn't expect more than about 125W power draw under load btw. It's just not good to use such a power supply.

A Corsair 430v2 for $17 after rebate and discount code... I wouldn't risk it.
