PSU's for SFF PC's

[Zak33]

I have an Aopen XC Cube, which Sair uses for Il-2,and which has been running a single HDD, a CD Burner, an XP1800 at 2600 and a Radeon 9000 OEM 128mb.

I got a 9500 Proon ebay, flashed to 9700 Pro speeds, for her, but it's very unstable, and the entire PC reboots randomly, from 15 minutes to an hour according to load.

I know the card is OK, as I whacked it into my main rig, Antex 430w zillion hdd etc and its rock solid.

I tried clocking it down to original 9500 Pro speeds and even lower, ( and weirdly got artifacts with ultra slow memory timings) but it still dies and reboots.

Can you get better PSU's for SFF or am I snookered? The 9000 OEM is back in and good as gold again.

Is it power or heat issues? YOu can get replacement/better psu's for shuttles but i don't know about the aopen ones.

could you not use a shuttle silentx psu in there? you can get them cheap and they are very good units.

might have too...its not heat...I took the case off, opened my windows and whacked a fan at it....took longer to reboot, but not much

The Aopen uses a custom SFF PSU I believe, making it next to impossible to replace without heavy mods. If you overclock you may need to consider an external PSU. I like the Monarch Hornet cases because they use a standard SFF ATX PSU and they have quite a bit more volume.

I don't believe your problem is power. You can try hooking up the PSU from your other rig (disconnecting the SFF PSU of course) to make sure though.

what do you think it is chap? I'd love to get it sorted, but its not heat. AGP voltage got upped to the max in an attempt for stability.

It FULLY REBOOTS the PC. Doesnt lock up

and now the original Radeon 9000 is in, its solid again.

(If it is the PSU)

AFAIK Aopen use FSP PSUs for all their normal cases - it's probably the same for the XCs too... Can't find any decent pictures on the net of the XC PSU but it LOOKS like one of these:

Apparently a 'CFX' PSU. The good news is that there's UK office for them and they were very friendly and useful last time I spoke to them (had a 1u PSU blow up in a server at my last company and wanted something beefier... FSP recommended 2 suppliers for what I wanted and said if they couldn't help out to call them back and they'd sort one out direct)

Edit: A bit more googling shows the code for the PSU being FSP220-60CU(PF) and there are a few places that sell them (looking at ~£40 though)... If it's the same size I'd try and find the 275W PSU instead... It's not much more but every little helps and all that...

Sounds like the PSU. Did you try hooking up the other PSU to the XC?
