Actually I think that there are better values in the Fortron/Sparkle line than the XClio now that the XClio no longer has any PFC as they did before (passive). There are some new models with the "TH?" suffix that I'd be looking at closely. I've never heard of a real dog in the Fortron Group's line - even in the budget "Q" lines.
. Just make sure it's not too heavy - don't know how much that tin-can Powmax case can take. Certainly not the 6 pound and oversized Delta 465 Watter I have here...

. But if you're interested, a guy (Totski) has a bunch of clean used ones for sale for $41. shipped (perhaps less if you want to chance a bid - lots have been won at the minimum bid). But you do have to rearrange the wires in the 24-pin ATX shell to the standard pinout and probably lengthen the wires for the P4 connection. It is also oversized at about 3 7/8" high and 6 1/4" deep (it is the standard 5.9" wide) - and it has a 92mm fan... In any case, it's magnificent at 39A between the two +12 outputs, full range input voltage control and active PFC (.97-.99 as measured here)!. They have plenty of useful life left in them.
. I got mine (in new condition) off ebay from somone else - and I won't tell you how much I paid as you would cry... HP sells new replacements for $150. and judging from the guts of these things, they are worth every bit of that.
Here are a couple of pix:
. These are the
PCBs of the DPS465AB-1A which was made for the HP X4000 dual Xeon workstation. The one on the left is the AC side and covers the entire top of the PSU. Full range voltage control and active PFC. The one on the right is the DC side which covers the bottom side of the PSU - 22A of +12 for the CPU(s) and 17A of +12 for the ATX and drive connections (they call it the I/O side) - 39A total +12! Above the PCBs you will see part of the chassis with the 92mm Delta dual ball fan and the IEC filter housing - most PSUs just use the connector, not the full filter unit.

Testing my rewiring job on my own main system - guts or insane, you decide
